Проект создан!

Дорогие друзья,

В предыдущем письме я немного коснулась проектов на платформе iNaturalist и его роли в мобилизации данных о биоразнообразии Югры. Сейчас хочу остановиться на этом вопросе подробнее.

Дело в том, что краудсорсинг (= любительская, или гражданская наука, citizen science) стал в последнее время одним из основных инструментов в сборе данных о находках видов. Это произошло в том числе благодаря появлению таких платформ как iNaturalist, где возможен быстрый сбор регистраций организмов по фотографиям и используется их машинное определение до вида. Роль краудсорсинга в экологии и изучении биоразнообразия хорошо описана в ряде статей, опубликованных на сайте GBIF https://www.gbif.org/citizen-science.

Сам GBIF является доказательством успешности этого подхода, где около 70% данных поступают из источников citizen science (iNaturalist, eBird и другие). В России можно привести пример проекта "Флора России", собравшего за один год более 200 (!) тысяч точек находок растений на территории нашей необъятной родины https://ru.wikipedia.org/wiki/Флора_России_(интернет-проект). По результатам этой работы коллеги сейчас готовят хорошую статью, соавторами которой станут активные участники проекта на iNat. Другой проект - наблюдения за биоразнообразием в Алтайском крае http://altainature.org/projects, где натуралисты (школьники и все желающие) с помощью iNaturalist активно участвуют в сборе данных о редких видах и подготовке издания Красной Книги.

Вдохновившись этими примерами, мы решили что пришло время активнее пропагандировать и развивать это направление в Югре. Мы создали зонтичный проект и внутри него - проекты на каждую природоохранную территорию Югры, а также общий проект биоразнообразия на всей территории и по отдельным группам организмов. Все эти проекты позволят нам вести отчет об успехах сбора данных на той или иной ООПТ и в рамках всей территории. Адрес проекта на iNat: https://www.inaturalist.org/projects/bioraznoobrazie-i-oopt-yugry-biodiversity-and-conservation-in-yugra-region

На настоящее время на территории Югры мы имеем около 3,3 тысячи находок организмов, сделанные примерно сотней участников. Из этого количества наблюдателей, постоянными iNatерами (т.е. сделали больше 50 наблюдений) являются только 10. Большое спасибо за работу bolotoved, entomokot, marasmius, nikolai_nakonechnyi, ana_lu, elenabutunina, usiaz, cavlp и всем, кто уже вступил в наши ряды!
Кроме собственно загрузки наблюдений, большую роль в проекте играют определяющие (эксперты). Здесь приняли участие 410 человек со всего мира, но только два эксперта из Югры сделали больше 50 определений (спасибо marasmius!).
По числу находок в разных таксономических группах, у нас лидируют грибы и растения (каждая по 36%), затем идут насекомые (16%) и птицы (7%).

Сильно отличается вклад природоохранных территорий в общее число данных. Сейчас активно поступают находки с трех территорий природных парков: Самаровский Чугас (131), Кондинские озера (75) (спасибо elenabutunina) и Сибирские Увалы (54) (спасибо nikolay_nakonechniy).

По статистике проекта "Флора России" - Югра находится на 49 месте из 85 регионов нашей страны. По-сравнению с некоторыми другими Сибирскими регионами, в Алтайском крае - 12,8 тысяч, Омской области - 7,3 тысяч, Новосибирской области - 5 тысяч, в Югре - 0,9 тысяч.

Я надеюсь, что созданный зонтичный проект и другие виды активности в этой области помогут использовать ресурс краудсорсинга для изучения и сохранения биоразнообразия региона. Что может сделать каждый:
1) стать активным участником iNat
2) распространять информацию об iNat среди сотрудников, студентов, СМИ, в соцсетях
3) ввести использование iNat в практику работы отделов эко-просвещения, на студенческих практиках, и других мероприятиях в Ваших организациях.

Со своей стороны я буду вести регулярный обзор проекта и сотрудничать с отделами эко-просвещения и другими научными и образовательными организациями для распространения информации о проекте.

До скорой встречи на iNat!

a day at Telford garden 30.10.2019

Telford garden is just a shopping center and private housing estate of Hong Kong. However, some flowerbeds become a paradise of migrants! Why? I think it is because the flowerbeds grow a lot of worms and flies. These are food for birds. Some grasshopper warblers are difficult to observe in the wild.They hide at the bottom part of grassland. People can only hear the sound. However, they are very easy to observe. When you look down the plants, you can see some warblers. These are grasshopper warblers. Most of them are pallas grasshopper warblers as they are the most common grasshopper warbler of Hong Kong. Another grasshopper warbler is lanceolated warbler. This spice is more rare than pallas. Three warblers and one lesser shortwing were observe together. A black browed warbler was hide in the bamboo. We need to preserve Telford and let it be a paradise of migrant forever.

Looking for new ideas related to iNaturalist? Part 3: Explore places

As mentioned many times, the objectives of our regional CNC projects are to encourage our entire community, old and young alike, to get outdoors, to explore, and to observe nature. Too often we think that we have to leave the Maritimes in order to go on an adventure. We hope that as part of the CNC you will learn that you don’t need to venture far from home.

Do you know exactly what lives just outside your door? Are you prepared to go outside and explore? What plants/weeds are growing in your yard? What lives under the rocks, behind the bushes, in the trees? What is growing next to the street and/or in cracks in the sidewalk?

Do you have a favourite park or green space in your neighbourhood? Plan to go on a solo adventure or get a group together and see if you can find as many species as possible. Challenge your relatives, friends, neighbours, coworkers, fellow dog walkers, anyone with a pulse …

Do you want to find new areas to explore? If you live in the urban Halifax area when was the last time that you explored local parks, gardens, and trails such as Point Pleasant Park, the Dingle (Sir Sandford Fleming Park), Fort Needham, the Public Gardens, or the Frog Pond? Have you ventured over to Dartmouth and visited Birch Cove Park or gone to Admiral Cove Park in Bedford? For more ideas of HRM places to visit click here.

Are you aware of the many trails in your area? Have you walked/hiked/biked/paddled any of the sections of The Great Trail? Check out the following iNat Great Trail umbrella project made for the 2020 CNC.

It isn’t necessary to have a car to get to many locations – perhaps you have access to a bicycle or perhaps you can hop on a bus.

During the CNC we hope that you will have many opportunities to observe nature in many different locations. It is not necessary for everyone to upload photos of every plant/animal that you see to iNaturalist. By signing up to iNat and sharing at least one observation you will help increase the #participants count. If you drag others along to keep you company encourage them to signup as well!

If you are out biking or hiking, consider looking around and observing nature at the start and end of your trip as well as during breaks. If you are keen take a few photos. Remember, photos don’t need to be uploaded to iNat immediately – wait and upload to iNat when back in a free wifi zone.

By sharing observations from many different locations, researchers will have access to a large pool of data required to study local, regional, national, and global geographic variations.

By exploring any location, you personally can gain an appreciation for the biodiversity all around us.

Although the CNC is restricted to a 4-day period following Earth Day we hope that you will enjoy using iNaturalist and will incorporate sharing observations of nature into your regular day to day routine. By exploring locations over periods of time you can/will observe seasonal and climatic changes. By sharing these observations with iNat, researchers (and the public) will have access to the data that they need to manage resources and study climate change.

Encourage others to come explore our Maritime provinces – We are lucky, we simply have to open our door, step outside, and an adventure can begin.

Looking for new ideas related to iNaturalist? Part 2: Explore online

Generally, when we talk about the Maritimes City Nature Challenge, we state that our objectives are simple – we wish to encourage people of all ages to get outdoors; to explore; to observe nature; to share observations; and to have fun. We have skipped over another important component of iNaturalist – the one where you can stay indoors and explore content already posted to iNat.

At this time of year many avid gardeners are indoors pouring over seed catalogues and making plans for spring. iNatters can also take advantage of inclement weather or long dark evenings and browse iNat content.

April and the City Nature Challenge will be here before we know it. Take advantage of free time now and use the iNat Explore feature to view observations from areas of interest. Perhaps come up with a list of places that you might wish to visit during the CNC. Perhaps there is a list of species that you want to find or gaps in species distribution that you wish to fill. Perhaps there are iNat projects that interest you that you didn't know existed - perhaps share a few of these in the comments section below!

To view iNat content from the six Maritime CNC areas we have set up an umbrella project – this project isn’t restricted to the CNC April time period. All observations ever shared from the 6 Maritime areas can be viewed here.

If while you are exploring iNat you stumble across a few observations of species that you recognize take a moment or two and provide a name – iNat works because the community assists with identification.

a day at Yuen Long park14.12.2019

Yuen Long park is located at the northwest of Hong Kong. There are many trees and grassland. These habitats are good for birds, especially thrushes. Common blackbird is the most common thrush in the park. 30 birds can be seen for a day. Another common thrushes are grey backed thrush and Japanese thrush. Up to 10 birds can be seen for a day. When I was walking along the grassland, a white's thrush appeared for a sudden! It is an uncommon winter visitor at Hong Kong and first time for me to meet it. Away from thrush, 20 of yellow billed gosbeak flew over trees. daurain red starts and oriental magpie robin played together. A good day!

South/Aldercroft side - 1/24/2020

Coverage: Aldercroft Heights Road intersection to stop sign.
10:24am - 12:22pm

Weather: Rather warm (70F when I returned to my car), partly cloudy. May have rained 3 days previously (not sure though - weathercat says yes, but that was in Santa Cruz, and I know that it also rained in Loma Prieta and Scotts Valley but it did not in Campbell.)
Rainfall: MTD 2.79in, YTD 15.141in (per http://www.weathercat.net/wxraindetail.php)

Vehicles: 13
Bikes: 5
Pedestrians: 0

178 dead newts, around 38 of them fresh
4 dead jerusalem crickets

Definitely 1 juvenile newt, 2 others that were more like "teenage" newts - do the teenage ones count as juvenile? I posted 3 that include my finger for scale. The one that's definitely juvenile I'll tag as such.

There were a lot more dead newts, particularly fresh ones, on the east-ish side of the road (further from the reservoir) than the west-ish side.

Check out this cool project taking place in the Pacific Northwest!

Hi TNBRC:

Take a look at this story board documenting wild-harvested plants in the northwest US:
https://www.fs.usda.gov/pnw/science-stories/northwest-huckleberry-and-other-nuts-and-berries

The USFS in that region is interested in conserving and restoring traditionally used plants, like huckleberry, salal, and hazelnut, to provide harvest opportunities for Native American tribes and local businesses, as well as provide forage for native pollinators and other species that depend on these food sources!

The TNBRC is taking a first step towards such an initiative by documenting where and with what frequency traditionally used plant species occur on federal lands in Arizona. With this knowledge, we can target species or regions for conservation and restoration projects in order to ensure that these resources persist for future generations. You are a part of that amazing effort - Thank you!!!

--Sara

Established Non-countable Birds in the Continental ABA-Area

Ever since seeing my first Great Tit visit at suet feeder in a park in Sheboygan, I have been fascinated by the fact that there are many established introduced birds in the ABA area that aren't on the checklist or in anyone's field guide (unless you own The Sibley Guide to Birds). After much research, here are some short profiles detailing all of the non-countable established introduced species in the Continental ABA-Area I could find:

Mandarin Duck - Aix galericulata
Mandarin Ducks were first noted in California in 1970, when hundreds were noted on a ranch in Healdsburg. This species was formerly found throughout much of the state, but it now seems to be restricted to the Los Angeles-San Diego area, the Sacramento area, and Sonoma. The species seems to be dependent on Wood Duck nest boxes in order to successfully breed.

A population of Mandarin Ducks also exists in Utah, in the Salt Lake City area. The first eBird record of a Mandarin Duck in Utah is from 1994, and they were first documented breeding in 2015.

Indian Peafowl - Pavo cristatus
Populations of Indian Peafowl exist in Florida, Texas, and California. It is found throughout much of California, but is best known in the LA area. According to local legend, the California peafowl were introduced by Elias “Lucky” Baldwin, who released the birds (imported directly from India) onto his property in 1880 (this land later became the Los Angeles County Arboretum). This is probably true, but peafowl are widespread enough that they probably came from a series of introductions around the state.

In Florida, Indian Peafowl are found throughout the peninsula. The earliest eBird record of a peafowl in Florida is from 1970. They were probably introduced separately to all of the major cities by homeowners as a yard decoration. This is somewhat ironic considering they are now viewed as a pest that destroys gardens and poops everywhere. In Miami (which has one of the largest populations) it is illegal to harm peafowl or their eggs. The Florida population actually consists mostly of hybrids with the Green Peafowl (Pavo muticus), (these hybrids are known in aviculture as Spalding Peafowl) but no pure Green Peafowl exist wild in the state.

In Texas, Indian Peafowl occur in Austin, Houston, Dallas, and Midland. The earliest of these is the Austin population, which were released around 1930 on private land that is now known as Mayfield Park. A small percentage of the Austin birds are Spalding Peafowl. The Houston population was introduced by homeowners in the 1980s. All of the Texas populations are slowly spreading into more rural areas, it seems likely that in a few decades the species could exist statewide.

Rose-ringed Parakeet - Psittacula krameri
Rose-ringed Parakeet populations exist in Florida and California. In California, the species exists in the Los Angeles area, San Diego, and Bakersfield. The Bakersfield population has been extensively studied by Ali Sheehey. They became established in 1977 after a large flock of them escaped from an aviary. The LA area and San Diego populations likely derive from escaped pets. The earliest LA area eBird record is from 1977, and the earliest San Diego record is from 1988.

In Florida, the species is found in the Naples area and probably came from escaped pets. The earliest eBird record of this species in Naples is from 1990.

Mitred Parakeet - Psittacara mitratus
The Mitred Parakeet exists in California, Florida, and possibly New York. In California, well-established in the Los Angeles area, which has been there since the 1980s.

In Florida, the species is present in the Miami area. The earliest eBird record of this population is from 1985.

This species is possibly present in Queens, New York. The birds were first documented around 1985 feeding in trees on a neighborhood in Queens. They showed up there every fall, then disappeared each spring. Juveniles would turn up every year with the rest of the flock, proving they were breeding, but no one knows exactly where they were breeding. I haven’t been able to find any online reference to this population since 2011, but I am not sure if this is because they no longer exist or because no one has been documenting them.

Red-masked Parakeet - Psittacara erythrogenys
Red-masked Parakeets are present in Florida and California. The first record of this species from California is from 1983, although it is likely that they were there before that and were confused with the very similar (and much more common) Mitred Parakeet. They occur in the Los Angeles, San Francisco, and San Diego areas.

In Florida, they are found in the Miami area, with the first record eBird record being from 1985.

This species will hybridize with Mitred anywhere they both occur.

Lilac-crowned Parrot - Amazona finschi
Lilac-crowned Parrots are present in Florida, California, and Texas. In California, they were first documented in 1976 and occur in the Los Angeles and San Diego areas. Unlike other introduced parrots, this species is actually spreading into more rural areas, including both lowland and mountainous regions.

In Florida, this species is present in small numbers in Miami, with the first eBird record being from 1983.

In Texas, Lilac-crowned Parrots are established in the Brownsville area. The first Texas eBird record of this species in Texas is from 1987.

This species will hybridize with the Red-crowned Parrot (Amazona viridigenalis) anywhere they both occur.

Black-throated Magpie-Jay - Calocitta colliei
The Black-throated Magpie-Jay is established in the San Diego area. It is a popular pet species in nearby Tijuana, Mexico, and the population is likely descended from escapees from there. It was first documented here around 2000.

Orange-cheeked Waxbill - Estrilda melpoda
The Orange-cheeked Waxbill is established in the Los Angeles area. It is quite a common pet species in the area and the population likely came from escaped pets. The first eBird record of this species from the LA area is from 1982.

Pin-tailed Whydah - Vidua macroura
The Pin-tailed Whydah is a well-established introduced species in the Los Angeles and San Diego areas. The earliest eBird record of this species from the southern California is from 1996. The species is a brood parasite, and it parasitises the nests of estrelids. Interesting, although some of its native hosts- most notably the Orange-cheeked Waxbill and the Northern Red Bishop (Euplectes franciscanus) - have been introduced to southern California, the only species it uses as a host in North America is the Scaly-breasted Munia (Lonchura punctulata), a species introduced from Asia. This proves that it can change hosts to a species they wouldn’t encounter in the wild in their native range. There are worries it may move on to native species.

This species is occasionally sighted in and around Houston, Texas and there may have a population there, but more research is needed.

Great Tit - Parus major
This species is established in the vicinity of Sheboygan, Wisconsin. They originate from a series of illegal bird releases outside Chicago in 2004. The species initially moved north to Milwaukee, where they were found until around 2010, when the entire population moved north to Sheboygan. Despite the amount of invasive European plants in the area they seem to prefer native forest and dune habitats.

European Goldfinch - Carduelis carduelis
The North American population of this species originates from the same release of the Great Tit. Unlike the Great Tit, however, this species originally stayed in the Chicago area, but quickly moved out into more rural areas. It is now found throughout much of northeastern Illinois and southeastern Wisconsin. They are not believed to be a threat to native species as they seem to feed almost exclusively on invasive European plants.

Red Junglefowl - Gallus gallus
Populations of the domestic form of the Red Junglefowl (AKA Domestic Chicken or G. g. domesticus) exist in Florida, California, and Texas. A population of the Burmese subspecies (G. g. spadiceus) exists in Georgia.

In California, a small population of Feral Chickens exists in Lincoln. I could find no other information on this population other than a couple of anecdotal reports of lots of chickens being there from a few birders.

In Texas, Sam Houston State University and the surrounding areas are also home to a population of Feral Chickens. I could find no history on this population other than that it is relatively large currently.

In Florida, populations of Feral Chickens exist in the Tampa area (the first eBird report being from 1979), the Miami area (earliest eBird report from 2007), and the Keys, being most common on Key West (first eBird report from 1993).

The Georgia population of wild-type junglefowl (known locally as Burmese Chickens) exist in the town of Fitzgerald. They were introduced by the state in the 1960s in a failed attempt to introduce the species as a game bird. Thousands exist in the town (more than 10 for every resident).

Blue-and-yellow Macaw - Ara ararauna
A population of this species may be found in Miami, where they have existed since the 1980s. They were increasing in numbers until quite recently, however they are now under intense stress from “legal poaching”. The effects of this species on the local ecosystem are not currently understood, so whether this a good thing or not is entirely unclear.

Common Hill Myna - Gracula religiosa
A small population is present in Miami, they were first recorded nesting there in 1973. Formerly common but is now seen only in small numbers.

Red-vented Bulbul - Pycnonotus cafer
Red-vented Bulbuls have existed in Houston since the 1950s. They are now common in many areas. They probably originated from released pets in the Woodland Heights area, although some biologists believe they may have been ship assisted.

Graylag Goose and Swan Goose - Anser anser and Anser cygnoides
These two species (as well as hybrids between the two) make up the common domestic geese of farms, zoos, and private collections. Escapees are incredibly frequent across the continental ABA-area, and it’s very difficult to tell where they are established and where they are simply frequent escapes. As far as I can tell there is population of A. anser in the Los Angeles area (it’s hard to tell if A. cygnoides is involved there or not) and population in Houston made up of A. cygnoides and hybrids.

Yellow-headed Parrot - Amazona oratrix
This species has populations in California and Texas. In California, where it was first documented in 1973, it is found in the LA and San Diego areas.

In Texas, it is found throughout the Rio Grande Valley. The earliest eBird report from the region is from 1960. It is possible that this population actually includes some wild vagrants, similar to the local populations of Red-crowned Parrot (Amazona viridigenalis) and Green Parakeet (Psittacara holochlorus).

Red-lored Parrot - Amazona autumnalis
The Red-lored Parrot has feral populations in the Los Angeles area and the Rio Grande Valley. In the LA area it was first seen breeding in 1997. The population is relatively small and it is usually found in mixed flocks with other amazons.

The earliest Texas eBird record is from 1985.

Blue-crowned Parakeet - Thectocercus acuticaudatus
This species has introduced populations in California and Florida. In California, the species is uncommon and local in San Diego, with the first eBird report being from 2007. A population formerly in the LA area appears to be gone.

The species is much more common in Florida, where it exists in the Miami, Tampa, and Melbourne areas. The first Miami area eBird report is from 1985. The first Tampa eBird report is from 1993. The first Melbourne area eBird report is from 1998. Single birds are occasionally seen elsewhere throughout the state, whether these involve escapees or wandering birds from the established populations is unclear.

White-fronted Parrot - Amazona albifrons
The White-fronted Parrot has been established in the Rio Grande Valley since at least 1982.

Orange-winged Parrot - Amazona amazonica
This species is established in the Miami area. The first eBird is from 1978.

White-eyed Parakeet - Psittacara leucophthalmus
Established in the Miami area. First eBird report is from 1987.

Chestnut-fronted Macaw - Ara severus
This species is established in the Miami area. The first eBird report is from 1978. It has declined in recent years but is still present relatively large numbers in certain areas.

“Japanese White-Eye” - Zosterops species
A species of white-eye in the recently-split Japanese White-Eye complex is established in the Los Angeles and San Diego areas as well as Santa Catalina Island. The species present is currently identified as Swinhoe’s White-Eye (Zosterops simplex), although this is tentative. Despite being introduced only as recently as 2009 they are currently one of the most common bird species in southern California. Based on the effect the introduction of the Warbling White-Eye (Zosterops japonicus) in Hawaii it is worried they may become quite a detrimental invasive species.

This is the only species on this that is not eligible of the ABA Checklist as it has not yet been present for 15 years.

You will note that many of these profiles lack much information. That's because birders don't seem to pay attention to these birds - so many seem to be in the mindset that if they aren't countable they should care. I suspect many are not added to eBird checklists, which makes finding info hard. I know for a fact that many of these species get marked as "not wild" on iNat.

You will also note that all of these bird (except the white-eye, as noted above) are eligible for the ABA Checklist. So why aren't they countable? I have no idea. Part of the reason I wrote this is to raise awareness for these birds.

I appreciate any information you might have on any of these birds, or even some populations of these species or others I may have missed in my research. I also recommend you go out searching for some of these birds, including uploading them to iNat and making sure to add them to your eBird checklists.

I plan to publish more posts on similar subjects in the future (like maybe looking into Hawaiian introductions) so stay tuned!

Welcome! A Quick Guide to Identification

Hi everyone! Welcome to the 2020 Brandeis Bioliteracy Project! This project will document any and all observations of wildlife found on and around the Brandeis campus during the spring semester. This is Isaiah, the curator of the project and a TA for Conservation Biology. As the semester starts up, many of you will be using iNaturalist for the first time. As such, you may have some initial difficulty with identifying the species that you document. Do not worry! It will take time and practice to recognize the plants, animals and/or fungi that you see. While iNaturalist has a built in identification feature, it is not always accurate. At times, it can be completely off, suggesting plant species when you photographed a bird. As such, do not rely on it entirely and take its suggestions with a grain of salt. Below is a short guide of tools and resources that you can use to help you identify the species in the observations that you make.

First and foremost, a great resource to consult is last year's project. The 2019 Brandeis Bioliteracy Project is a complete list of all observations made last spring. If you go to the species tab, you can see a breakdown of the most commonly found species. Using search, you can break it down into categories like birds, plants, mammals, etc. With lots of high quality observation photos, this is a great place to look if you are unsure of a species' identification.

For plant identification, Go Botany is a really helpful website. They have a breakdown guide where you can enter some basic characteristics and it will give you a list of potential candidates. By answering more questions in the sidebar, you can narrow it down further.

For identifying birds, the Mass Audubon Society has some great resources on the common bird species of Massachusetts. The site also breaks it down by fall/winter and spring/summer birds. In general, they also have some great resources on other forms of wildlife like mammals, reptiles & amphibians, insects & arachnids, and more.

Cornell's Lab of Ornithology also has some great birding resources. They created an app called Merlin that is available on Android and iOS that is a fantastic resource for bird identification. You can enter some basic characteristics and location of sighting and it will give you some suggestions with great accuracy. Their website also has some high quality photos you can browse if you have some idea of what you are looking at.

The library also has some great naturalist guides that can be checked out. I am a big fan of Roger Peterson's field guides, but there are a lot that all focus on different groups of species (trees, birds, butterflies, etc.). They have full color illustrations and detailed notes on descriptions as well as similarities and differences from other species.

Finally, if you have any questions on iNaturalist, the project, an identification, or just want to say hi, you can reach out to me at ifreedman@brandeis.edu. I would be happy to talk or answer any questions that you have. I look forward to seeing all of your observations over the course of the semester!

Looking for new ideas related to iNaturalist? Part I: Explore indoors

It is 6am, the sun isn’t up yet, and it is very dark outside. I am spending a few days at our cottage and early mornings here are very peaceful - the fire is glowing nicely, and I have few lights on as I upload observations to iNaturalist. But I know that I am not alone – I can hear the resident mouse as he is rustling around in the bin of kindling in the corner by the wood stove…

Yesterday I found a weird (i.e. new to me) ‘bug’ in the bathtub. I knew that it wasn’t a spider nor was it a tick. To help figure out what it might be of course I took a photo…and posted this to iNaturalist.

After a couple of cups of coffee my mind started to spin, and this lead me down a new rabbit hole which has led to this blog.

I fired off the following question to an iNat City Nature Challenge group: ‘If a beetle/spider/insect is found indoors should it be flagged as 'captive?' (We have lots of bugs inside as we bring in wood for the fireplace…)

I received the following reply: ‘species are still considered wild unless we intentionally bring them indoors.’

I was also sent a link to a very relevant iNat project: Never Home Alone: The Wild Life of Homes.
Info on this site incudes a great video where they explore someone’s house looking for spiders, etc. I quite enjoyed it – it did help knowing that the video was created in the States and our Canadian homes are less likely to have quite so many spiders… To view the movie click here.

Last evening, I went off to explore our basement…bad timing as the cottage had just been vacuumed earlier in the day but I did find a couple of spiders!

If from time to time you find critters indoors and you upload your observations to iNaturalist then consider joining the ‘Never home alone’ project. This iNat project does require that observations are Research Grade so you will have to put in a bit of effort to get your observation identified.

Below are a few recommendations if you post ‘indoor’ content.
1. Add an observation field: ‘Habitat’ and then populate this field with ‘dwelling’. (It will indicate that they were not observed outdoors in a natural setting.)
2. Add a tag: ‘indoors’ (This will facilitate filtering out this collection of critters – useful for identifiers)
3. Add observation to the Never home alone project (you must join this project first and then your observation must be Research Grade)
4. Encourage spider/insect/bug experts to monitor iNat and assist with the identification process.
5. Encourage others to explore indoors!

Here is a link to a few of my iNat indoor observations – if you recognize any please help identify!

Here's why 30 sea lions are popping up around San Francisco this year.

Sea lions have already invaded Pier 39 more than three decades ago, waddling and barking in a perpetual blubbery mass that became a fixture of the Embarcadero’s sun-faded docks.

Birds in California's desert are dying.

The world is heating up. According to NASA's Global Land-Ocean Temperature Index, 19 of the past 21 years have been the hottest on record. This dramatic increase in temperature and other more subtle climate changes have been pronounced in the California desert, where temperatures have increased almost four degrees in the past 100 years.

Приветственное слово

Дорогие друзья и коллеги, добро пожаловать в проект, посвященный самым интересным находкам видов животных, растений и грибов, включенных в Красную книгу Республики Татарстан!
Не успел проект появится, как в нём уже значится почти тысяча находок редких видов. Надеюсь, что проект будет ежегодно пополнятся новыми встречами и позволит еще более эффективно собирать сведения об охраняемых видах нашего родного региона.
В настоящий момент в список видов проекта внесены не все виды, включенные в Красную книгу. Это связано в первую очередь с тем, что большая их часть попросту отсутствует в базе iN. Эту проблемы мы будем впоследствии решать. Есть и еще один дискуссионный момент - вносить ли изменения в состав охраняемых видов (в проекте), которые произошли уже после издания Красной книги, а именно - по решениям (а таковых было уже несколько) комиссии по ведению Красной книги? Думаю, да, но об этих изменениях я обязательно сообщу в виде очередной новости. Ну а пока желаю нам всем плодотворных путешествий и интересных находок!
С ув., админ.

The Western Monarch Mystery Challenge

The Western Monarch Mystery Challenge is a campaign running from February 14th to April 22nd, to collect more records of where western monarchs spend the spring in California, after leaving the overwintering sites.

Western monarchs are at less than 1% of their population size in the 1980’s and the situation is alarming. The Western Monarch Mystery Challenge is a campaign to find out where western monarch butterflies are in early spring. We know they spend the winter months (November to February) in groves along the California Coast, and start breeding in central California as early as February. However, we know a lot less about where they are and what they’re up to in February, March, and April. Solving the mystery of where western monarchs spend the spring is central to conserving and restoring the phenomenon of monarch migration in the West.

How to participate is simple:

-If you see a monarch outside of overwintering groves, take a picture! (don’t worry, it can be far away and blurry)
-Report it to iNaturalist OR email it to MonarchMystery@wsu.edu
-Be automatically entered to win a variety of prizes every week you report a sighting

If you upload a monarch photo - from outside the overwintering sites - you will be automatically entered in a weekly prize drawing. We will choose winners every week from Valentine’s Day (Feb. 14) to Earth Day (April 22). Prizes will range from gift cards to REI or Patagonia to other goodies.

By reporting an observation, you will be adding to our community science program, the Western Monarch Milkweed Mapper, a great way to see our knowledge of western monarch grow.

Here’s how the entry process works:

Each photo is an entry. So if you submit 3 photos in a week, that is 3 entries for the prize that week.
Each week you are eligible for new prizes, even if you submitted sightings and won prizes the week before. (No duplicates of the same monarch in the same place in the same week)

If you want to participate but do not see a monarch, you can be entered to win prizes by becoming a monarch ambassador. To be an ambassador:

Share the Western Monarch Mystery Challenge on social media
Use #monarchmystery and tag our accounts listed below
OR be a neighborhood ambassador through NextDoor - anywhere in California, particularly in the coast range and Central Valley where we suspect monarchs are most active in the spring.

*Please do not submit sightings from monarch rearing projects. They skew data and could jeopardize the quality and legitimacy of conservation plans. Only “wild” monarchs are to be reported.

Media accounts, hashtags, and contacts:
(bolded hashtags are necessary)

Western monarch butterfly population still at critical level

PORTLAND, Ore., January 23, 2020—The Xerces Society today announced that the number of monarch butterflies overwintering in California remains at critical levels for the second year. The monarch population during the 2018–19 winter was an all-time low. Unfortunately, this year’s Western Monarch Thanksgiving Count numbers are no better.

The total number of monarchs counted this year was 29,418. Although this is 2,200 more than last year, it comes as a result of greater survey effort, with volunteers visiting more sites. There is no meaningful difference between the western monarch population this year and last.

In addition, in both years the population has been less than 30,000 butterflies, the threshold below which the migration may collapse.

“We are disappointed by the numbers of year’s Western Monarch Thanksgiving count,” said Emma Pelton, the Xerces Society’s Western Monarch Lead. “We had hoped that the western monarch population would have rebounded at least modestly, but unfortunately it has not. The silver lining is that the population didn’t shrink any further. There are still thousands of monarchs overwintering along the coast, so we can take heart that it’s not too late to act.”

Identifying Mexican and Central American Red-tailed Hawks

Recently, I've made several posts in regards to Red-tailed Hawks and it's subspecies. In my first journal post, "Identifying US and Canada Red-tailed Hawks", I explained in thorough detail the differences between Red-tailed Hawk subspecies in that area. I've had thoughts to do a similar post for countries not mentioned above as well and now I'm doing it. But also note that Mexican, Caribbean and Central American Red-tails are very ill-studied and future research may prove invalidity of subspecies or more depending on what researchers find. INaturalist is a great platform to find out the variety of the species so perhaps a little description of each subspecies may help users. All information used here is gathered from photos on iNat/ebird and research papers (usually the describing paper) in regards to the subspecies. Here we go!

Non-Migratory Caribbean Subspecies

The Red-tailed Hawk lives on nearly every island in the Greater Antillean and are vagrant to the Lesser Antillean (probably US migrants though). There are 2 subspecies.

Jamaican Red-tailed Hawk (Buteo jamaicensis jamaicensis)

Range: Jamaica, Hispaniola, Puerto Rico and norther Lesser Antillean Islands

Head: Normally rich brown with no markings. Throat is dark.

Upperparts: Same brown as head with blackish-brown mottling. White scapular mottling light.

Underparts: Bellyband variable from lightly to heavily-marked. Bellyband is normally blackish and often has barring. Rufous wash often occurs on the sides of the breast. Legs are typically unmarked. Breast and legs are white but can have a buff wash.

Wings: Patagials very thin and often has white markings encroaching on it.

Tail: Tail lacks tail banding and subterminal band is very thin. White uppertail coverts.

Morphs: Only light

Juvenile: Heavily marked below, white breast and considerable amount of white in the face.

Notes: Nominate subspecies, described in 1788. Comparing photos on iNat and eBird, I believe there's a good chance there might be geographic variation in the subspecies. I noticed individuals in Jamaica had very thin patagials and lightly to moderately marked bellybands. However, Hispaniola and Puerto Rico hawks, nearly every individual had incredible heavy bellybands, some where the entire belly was black. Patagials were also thicker and breast had rufous, not buff, tones. Subterminal band also appears broader in Puerto Rican individuals. I suspect some research needs to be done.

Photos: (1) Lightly-marked Jamaican Red-tailed Hawk -- Jamaican form (2) Moderately-marked, thick patagial Jamaican Red-tailed Hawk -- Hispaniola form (3) Heavily-marked, thick patagial Jamaican Red-tailed Hawk -- Puerto Rican form (4) Juvenile Jamaican Red-tailed Hawk -- Hispaniolan form

https://macaulaylibrary.org/asset/55235571#_ga=2.25765437.1609460285.1574228334-1175263981.1555651889

Cuban Red-tailed Hawk (B. j. solitudinis))

Range: Cuba, Bahamas and Isle of Pines.

Head: Quite variable. Most common head pattern is a rich brown unmarked head with dark throat but can have a darker malar or white throat. Some Bahama individuals have very pale, "washed out" heads.

Upperparts: Variable but is usually a shade darker than the head. White scapular mottling light to heavy depending on the darkness of the upperparts/head.

Underparts: Light to moderately-marked bellyband with rufous (Cuba) or white (Bahamas) breast. Rufous wash can occur on the sides of the breast. Rufous wash is usually present in the bellyband. Barring uncommon and does not occur on flanks.

Wings: Moderately prominent patagials, white unmarked underwing coverts.

Tail: Subterminal band moderately thick and red tail is usually lacks banding.

Morphs: Only light

Juvenile: Moderately to heavy bellybands with black markings on the sides of the breast making an incomplete breast band.

Notes: Appears to differ from jamaicensis by having thicker patagials, broader subterminal band and lighter bellybands. They are also darker dorsally and head coloring is more variable. Also keep in mind that Bahama individuals appear to be more variable than Cuban individuals and it may suggest geographical variantion but the variations are not nearly to the extent of jamaicensis on their islands.

Photos: (1) Heavily-marked, rufous-breasted Cuban Red-tailed Hawk -- Cuba form (2) Moderately-marked, rufous-breasted Cuban Red-tailed Hawk -- Cuba form (3) Pale-headed Cuban Red-tailed Hawk -- Bahamas form (4) Moderately-marked, bellyband washed Cuban Red-tailed Hawk -- Bahamas form (5) Heavily-marked, incomplete breast-banded juvenile Cuban Red-tailed Hawk -- Bahamas form

Non-Migratory Central American Subspecies

Central American hosts 7-8 different subspecies of Red-tailed Hawk and the variation between them is amazing. Also note that most non-migratory Central American subspecies are residents of the mountains and highlands. If you happen to see a Red-tailed in the lowlands, it's probably a migrant from the US.

Western Red-tailed Hawk (B. j. calurus)

Range: Resident and breeder to Baja California. Winter visitor throughout Mexico but recent evidence suggests that they migrate and winter all the way to Panama.

Head: Throat mostly dark, some have streaked, collared or white throats and these variations seem to occur more often in northern Canadian breeding areas or southwestern US deserts.

Upperparts: Very dark brown, white scapular mottling is light and barely visible comparative to other subspecies, however it is visible enough to use as an id feature to distinguish from other Buteo species.

Underparts: Perhaps the most variable subspecies in terms of underpart markings. Bellyband can vary from a few streaks and barring on the flanks to a thick black band across the belly with barring extending into the breast. Though typical bellybands have barring on the flanks and belly.

Wings: Almost all individuals have tawny or rufous underwings that contrast with the whit remiges. Patagials are dark and noticeably thick, making a huge "U" shape cut on the humerus region. If the bird is in wing, these two features are key to whether your Red-tailed is Western or not.

Tail: Incredibly variable from the "classic" all red-tail with thin subterminal band to a thickly banded tail with no distinct subterminal band. Also note where the wingtips end on the tail. Eastern/Northern Red-tails have wingtips barely extending past the uppertail coverts while calurus can extend from midway across the tail to the tail tips.

Morphs: Light, Rufous, Intermediate (only juveniles) and Dark. However light morphs dominate other morphs and from a compilation of photos I did for research about 96% of all calurus Red-tails are light morphs and 3% are rufous morphs.

Juvenile: Throat usually dark but younger individuals may have white throats that resemble borealis or abieticola. To distinguish light morphs from other subspecies, look for heavily marked bellyband and underwings. Only subspecies that have intermediate and dark morphs which is heavy markings on the breast (intermediate) or black underparts with white streaking, similar to Harlan's juveniles (dark).

Photos: (1) Dark-throated moderately-marked light morph calurus. (2) Tawny-breasted heavily-marked light morph calurus. (3) Lightly-marked calurus. (4) Dark morph juvenile calurus. (5) Heavily-marked rufous morph calurus. (6) Lightly-marked rufous morph calurus. (7) Flying molting very lightly-marked light morph calurus -- note thick patagials. (8) Flying typical light-morph calurus. (9) Flying dark morph calurus -- note that this was a breeder I observed all season and if you see something like this in the field and this is your only shot, best identify it as rufous/dark morph. (10) Dark morph calurus with very thick subterminal band.

Fuertes or Southwestern Red-tailed Hawk (B. j. fuertesi)

Range: Throughout northern Mexico with the range limits believing to be Durango and Tamaulipas.

Upperparts: Light to moderate whitish or buff scapular mottling.

Underparts: Very little to no bellyband and if markings do show, it's only two or three streaking marks. Western Mexican (aka Arizona) individuals appear to have more streaking (more being visually similar to a very lightly marked borealis) and even barring on rufous washed flanks.

Wings: Underwings completely white with the exception of thin but dark patagials and "chevrons" where the primary coverts end.

Tail: Tail is pale red with a thin subterminal band.

Morphs: Only light morphs.

Juvenile: Similar to borealis but with longer wings and bellyband has a distinct "V" shaped patterning where borealis is just streaking.

Notes: It is disputed if this is even a subspecies or just another form of borealis.

Photos: (1) Arizona fuertesi -- note slight rufous wash. (2) Arizona fuertesi on the far end of markings. (3) Flying Texas fuertesi on the far end of markings. (4) Flying Arizona fuertesi.

Sutton's Red-tailed Hawk (B. j. suttoni)

Range: Sierra de San Lazaro of Baja California

Head: Rich brown with dark throat or white throat.

Upperparts: Richly mottled upperparts with white scapular mottling light to moderate.

Underparts: Very little markings to the bellyband or can be absent overall. Typically has a rufous wash to the breast.

Wings: Dark, thick patagials with slight rufous wash to underwings.

Tail: Appears to be variable from brick red with very thin subterminal band to maroon with dense tail banding.

Morphs: Light and possibly dark.

Juvenile: Probably similar to calurus.

Notes: This is an incredibly understudied subspecies and perhaps not a subspecies. Neither iNaturalist nor eBird recognize the taxon but Avibase and Handbook of Birds of the World (HBW) however too. It is possible the subspecies is not well recognized because it was described by Dickerman (1993), quite some time after the American Ornithological Society (AOS) stopped doing assessments in their taxonomic updates. In a nutshell, the description of the subspecies was morphically intermediate between calurus and fuertesi, and measurably smaller. You can read what Dickerman said here -- https://www.jstor.org/stable/30054375?seq=1

Photos: (1) Possible Sutton's Red-tailed Hawk, note almost no bellyband. (2) Possible Sutton's Red-tailed Hawk, note rufous-washed breast. (3) Flying possible Sutton's Red-tailed Hawk.

Mexican Highlands Red-tailed Hawk (B. j. hadropus

Range: Varies by source. Presumed to be Mexican Highlands from Jalisco and Veracruz to Oaxaca. See notes.

Head: Rich rufous-brown with darker malar. White throat normally with collar.

Upperparts: Moderate to heavy white scapular mottling. Upperparts are a strong gray-brown.

Underparts: Light bellyband with dark teardrop-shaped streaking, though an absent bellyband (see notes) is not unusual. Flanks are very contrasting rufous compared to buff or white underparts.

Wings: Dark but thin patagials with rich buff underwings coverts. Banded remiges are well visible both dorsally and ventrally.

Tail: Variable in tail banding and color but it appears the main feature is, is that the 'subterminal band' is actually the tail tips with no visible red or white below the band.

Morphs: Light, rufous and dark. Differs from calurus rufous/dark morphs with white scapular mottling and black terminal band. See notes.

Juvenile: Unknown. See notes.

Notes: Incredibly understudied subspecies. The only published paper on the subspecies is the description paper (Storer 1962). He describes the range as being Jalisco to Oaxaca. Avibase and HBW claim the range goes to east coast of Veracurz. However no ebird photos of breeding Red-tails in hadropus purpose range show any of the features Storer claimed to be diagnostic. The individuals photographed in Jalisco, Guerrero and Socorro looked very much like kemsiesi or perhaps fuertesi. However a photo in Veracruz shows a Red-tailed that shows every feature Storer described in his paper and the features appeared to be consistent with all Veracruz and Puebla individuals. It is possible that hardropus is an eastern Mexican subspecies not western. However, a breeding dark morph individual was photographed in Guerrero and a rufous morph in Veracruz. Storer reported both hadropus and kemsiesi having dark morphs and we know fuertesi only occurs in light morph. So assuming that western Mexican Red-tails are not hadropus, it can be hypothesized that kemsiesi is not geographically separated by the Isthmus of Tehuantepec as originally believed and is the subspecies breeding from Jalisco to Nicaragua. Also in support of this hypothesis is the fact no hadropus individuals were photographed in western Mexico and vice versa for eastern Mexico. In southern Mexico, only one juvenile has been photographed in Puebla, subspecies undetermined but it may possibly be hadropus. The individual showed a heavy bellyband, dark throat, broader patagials and barred flanks. You can read Storer's paper here: https://sora.unm.edu/sites/default/files/journals/condor/v064n01/p0077-p0078.pdf

Kemsies Red-tailed Hawk (B. j. kemsiesi)

Warning! Theoretically, there is no "common name" for this subspecies but every other subspecies besides this one does and Kemsies is the Latin translation of the scientific name (Kemsies was a Yellowstone park ranger). I'm wondering if a better name can be applied such as the Sierra Madre Red-tailed Hawk to describe it's range.

Range: Chiapas, Mexico to northern Nicaragua. Though photographic evidence suggests that the Isthmus of Tehuantepec is a geographic "break" in their breeding range and they may live all the way up into Jalisco. See notes.

Head: Dark brown. Differs from other subspecies with dark auricular and cheek, not malar.

Upperparts: Light to moderate white scapular markings. Very dark charcoal-brown upperparts.

Underparts: Buff or white underparts with little or no bellyband. Whatever streaking they may have will be more prominent on the flanks. Belly can have a rufous wash that forms a "bellyband".

Wings: Patagials dark and moderately thick. Buff unmarked underwing coverts. Remiges are prominently banded both ventrally and dorsally.

Tail: Variable from brick red to pale chestnut-red. Subterminal band broad and prominent. Tail banding not uncommon. Uppertail coverts are whitish including bases to interior rectrices.

Morphs: Light, rufous and dark. See notes.

Juvenile: Variable, not studied hard so differences from other subspecies is uncertain.

Notes: Photograph evidence suggests that the subspecies range is not restricted the Nicaragua lowlands and the Isthmus of Tehuantepec and it may very well breed in western Mexico. Second issue about range is that most authorities claim kemsiesi range ends in Nicaragua but ebird reports that subspecies costaricensis is the expected subspecies for Honduras, El Salvador and Nicaragua and kemiesi being rare. However I cannot find any individuals photographed and identified as costaricensis appearing similar to "real" costaricensis in their breeding range in Costa Rica and Panama. Most of the reporting are probably misidentifications. They are variable in morphs and there appears to be quite a few rufous and dark morph breeders in their range. However it has been undetermined how dark morphs differ from hadropus. Dark morphs do differ from calurus with white scapular markings not buff or solid brown. Rufous morph differences are unknown as well. Juveniles are hard to place on subspecies especially when most juveniles photographed in the subspecies range are in spring, suggestable that some may not be resident birds. Further study is needed to determine differences.

Costa Rican Red-tailed Hawk (B. j. costaricensis)

Range: Though all authorities (including the Clements Checklists) claim this subspecies range to be Costa Rica and western Panama, ebird reports having this subspecies being the expected subspecies throughout central America from Honduras and El Salvador to Panama, though it is expected that most if not all the sightings north of Costa Rica are actually kemsiesi.

Head: Solid rich brown-rufous. Collared throat, often with brown streaking on the white throat. Throat can be almost solid brown.

Upperparts: Light to almost no white scapular mottling. Very dark charcoal-brown upperparts with dark feather tips, giving a mottled appearance.

Underparts: Unique to the subspecies. White breast and very rufous-pink (like rotisserie chicken color, there I said it) belly. If a bellyband is present, it is lightly marked and the markings on the contrast line of the white breast and rufous belly.

Wings: Dark, thick patagials with rich rufous underwing coverts, identical in color with belly and in flight, makes the white breast more distinctive. Remiges are prominently banded.

Tail: Not quite as variable as other subspecies, seems to be relatively consistent for the tail to be between rotisserie chicken rufous to slightly redder but not quite the classic brick red. Tail normally has no subterminal band but a broken or thin subterminal band can be present in some individuals.

Morphs: Light

Juvenile: Like adults except throat is whiter. Bellyband can be heavy but the markings are pale. There is prominent streaking dribbling into the sides of the breast.

Notes: This is perhaps the most unique-looking subspecies in the entire Red-tailed spectrum.

Mexican Island Endemic Subspecies

There are two subspecies of Red-tailed Hawks that are endemic, meaning they live nowhere else, to offshore Pacific Islands in Mexico.

Tres Marias or Smoky-colored Red-tailed Hawk (B. j. fumosus)

Range: Tres Marias Island chain off the coast of Nayarit.

Head: Dark brown overall, including throat.

Upperparts: No scapular mottling. Dark brown upperparts the same color as the head.

Underparts: Dark brown-rufous mottled breast with rufous barring belly and flanks.

Wings: Dark, thick patagials with heavily marked underwing coverts.

Tail: Fairly consistent, rufous tail with thin or no subterminal band.

Morph: Rufous

Juvenile: Like adults except throat is white and collared and tail is finely banded.

Notes: Understudied subspecies as very few photos have been obtained (ebird has none). It may be possible that light or dark morphs exist but because of it's range isolation it is hard to obtain photos. To our current knowledge, only "rufous" morphs exist and is explanatory to the secondary name Smoky-colored Red-tailed Hawk.

Photos: (1) Adult Tres Marias Red-tailed Hawk. (2) Flying adult Tres Marias Red-tailed Hawk. (3) Juvenile Tres Marias Red-tailed Hawk.

Socorro Red-tailed Hawk (B. j. socorroensis)

Range: Socorro Island off the coast of Colima

Head: Solid brown, best described in my words as the discoloration in old milk chocolate.

Upperparts: Solid brown like the head with no scapular mottling.

Underparts: Bellyband lightly-marked with smoky-tawny underparts.

Wings: Unknown in rufous morphs. Dark morphs have solid dark underwing coverts.

Tail: Unmarked brick red tail with very broad subterminal band. Uppertail covert color unknown.

Morph: Light morphs (only juveniles), rufous and dark, though dark appears much more common.

Juvenile: Much more variation than adults. Intermediate morphs appear most common and have a arid dirt color with pale spotting on the marginal coverts. Light morphs are very heavily-marked with only a small patch of the breast white. Some appear to have very heavy upperpart spotting while others show scalloped marginal coverts.

Notes: Understudied subspecies and only photos of the subspecies occur on iNat. It's possible that light morph adults exist but range isolation and sensitivity limit a person's ability to study them.

Photos: (1) Adult dark morph Socorro Red-tailed Hawk. (2) Adult lightly-marked rufous morph Socorro Red-tailed Hawk. (3) Flying adult dark morph Socorro Red-tailed Hawk. (4) Juvenile intermediate morph Socorro Red-tailed Hawk. (5) Juvenile spotted Socorro Red-tailed Hawk

Migratory Subspecies

There are several subspecies that migrate into Mexico and Central America but do not breed in area. There are three migratory or wintering subspecies.

Eastern Red-tailed Hawk -- Buteo jamaicensis borealis

Range: Confirmed sightings includes several in Costa Rica, Tamaulipas, Quintana Roo and Cayman Islands, but probably migrates throughout Central America, eastern Mexico and Greater Antillean.

Head: White supercilium is common. Throat is usually white, streaked or collared; dark throat is rare. Malar/cheek region usually dark.

Upperparts: Scapulars are moderately to heavily mottled white.

Underparts: Lightly to moderately marked bellyband. Barring occurs often on the flanks, rarely anywhere else. Breast almost always white but tawny does occur.

Wings: No rufous on the underwings. Patagials are thin or dull. Limited underwing markings.

Tail: Nearly all individuals have white uppertail coverts. Subterminal band thin to moderate. Partial or incompletely tail banding is uncommon. Nearly all individuals have white tips to the tail.

Morphs: Only light.

Juvenile: Throat almost always white, supercilium often white, bellyband light to moderately-marked.

Photos -- (1) Clear-cut example of borealis. (2) Lightly-marked streak-throated borealis. (3) Clear-cut flying example of borealis. (4) Flying moderately-marked streak-throated borealis.

Krider's Hawk -- B. j. kriderii

Range: No confirmed reports in Mexico or Central America but there are many sightings along the Rio Grande in Texas, and water isn't hard to cross for hawks.

Head: Varies but is normally very whitish. Palest form has nearly completely white head. Darkest form has dark cheek and crown.

Upperparts: Heavy white scapular mottling and scalloping pattern is well defined on the rest of the upperparts.

Underparts: Little to no markings on the underparts and whatever markings an individual may have will be a few streaking. Underparts may have a buffy look, especially when compared side-by-side with the incredibly similar light morph Harlan's.

Wings: Patagials nearly none existent and thin with completely white underwing coverts. When compared to Harlan's look for buffy underparts, banded remiges and reddish-white tail with no other markings.

Tail: Variable with half of the tail being red to completely white. If the rectrices have a white base and reddish tail extends past half the tail, that's a solid candidate for Eastern X Krider's intergrade.

Morphs: Light only.

Juvenile: Heads are typically whiter than adults and white upperparts mottling is even more noticeable. Tail with whitish with banding.

Photos -- (1) Dark Krider's Hawk. (2) Lightest form Krider's. (3) Flying intermediately dark Krider's -- note buffy underwings. (4) Juvenile Krider's. (5) Flying juvenile Krider's.

Harlan's Hawk -- B. j. harlani

Range: Only two confirmed sightings in Mexico (Baja California Sur and Durango) but there are many sighting along the Rio Grande so it's easy to assume they winter in Tamaulipas.

Overall body difference: Besides I find Harlan's such a unique bird, I'm not going to go through all the body part features. All you need to know is; they are either black and white or cool brown and white, tail is incredibly variable from reddish mottled to brown mottling to white with reddish tip. Light morph adults can appear incredibly similar Krider's and are often misidentified in Western US but they differ with colder brown tones, white tail with mottled tail (usually in light morphs) and lack of buffy underwings. Harlan's also frequently show unbanded remiges and thicker patagials. Some Harlan's have Some juveniles can appear very calurus-looking but they differ with having "V" shaped tail banding.

Morphs: Around 84% are dark morph or intermediate morphs and the rest are light.

Photos -- (1) Light morph Harlan's. (2) White-spotted dark morph Harlan's. (3) Same dark morph Harlan's but shows awesome tail pattern. (4) Intermediate morph Harlan's. (5) Flying juvenile intermediate morph Harlan's. (6) Dark morph Harlan's.

Final Words and Overview

So there you go, all 15 Mexican, Central American or Caribbean Red-tailed Hawk subspecies. Most of endemic, non-migratory subspecies are poorly studied and as new information comes forth, we can better understand them. I believe iNaturalist is a great platform to find out this research and it appears we have a very strong Mexican community compared to ebird.

I believe that southwestern Mexico should be a place closely observed to see if it's true that Kemises' Red-tails really do reside there, along with Baja California Sur and see if the Sutton's Red-tailed really deserves subspecies status.

Also, another shoutout to all of those contributing their sightings and sharing their thoughts on subspecific ids. I hope this post will help you feel just a little more confident in identifying Red-tails.
