Commentary: As a birder, I see the effects of climate change every day. Now, Audubon has quantified the threat.

For serious birders who regularly observe birds in the wild, ignoring climate change isn't possible. We have been seeing and documenting the effects of a warming climate since at least the 1950s.

Now we're a collection project

I just converted our Boyle Outdoor Education Centre project into an iNaturalist collection project. That means that we no longer have to manually add observations to the project. iNat NZ will now automatically add all observations from within the Boyle Outdoor Education Centre general area to the project.

We use the Boyle River area polygon, at https://inaturalist.nz/places/boyle-river-area, to determine which observations automatically go in.

Nature Walk in Crossings Park - October 14, 2019

I went home for fall break, and I took a walk in a park in my hometown of Albany, New York called the Crossings. The weather was warm compared to Boston, the temperature being about 70 degrees. There was very light wind. I walked with two of my high school friends, and it was very nice to talk to them while observing autumn leaves and other plants. I saw many different types of plants, from pine trees to milkweeds. There were even mosses on the ground in some dark places of the park. Many of the trees' leaves were turning red and yellow due to it being autumn. There weren't very many wild flowers to observe, and most of the flowers I saw around the park seemed to be planted by humans. There were a lot of people in the park taking walks, biking, and walking their dogs. Overall, this walk was a very calming and enjoyable experience.

Fourth Nature Walk in Colonie Town Park: October 14th, 2019

Today I went for my fourth nature walk of the year. On my previous three nature walks I went to Edmands Park which is located close to my dorm at Boston College, but since I was home for the weekend I decided to try out somewhere new! This week I walked around the Colonie Town Park which is located just outside of Albany, NY and is nestled along the Mohawk River. It was an afternoon walk, around 4:30, with the temperature coming in just above 60 degrees. On this particular walk I was specifically looking for plants to observe. Right from the start I identified Asters and Allies, which are a type of plant which I identified multiple times back at Edmands Park. As I walked around more I went down by the river and observed some Bulrushes and Cattails, which were cool as they deviated from what I normally observed. Overall it was a great walk and I found many different plants, some of which I had previously encountered, and some that I had never seen before!

Still here

My hummingbirds are still here. They're getting nutrients more from the flowers than the feeders.

Jordan - iNaturalist World Tour

We end Week 16 of the iNaturalist World Tour in Jordan. The top observer is @cliygh-and-mia with observations clustered around the capital Amman. Several other top observers have observations near Amman such as @khaled5 who works as a tour guide across Jordan. Ecologist @ronf and Jerusalem Botanical Gardens botanist @fragmansapir are in Israel on the map because of all their observations in neighboring Israel, but they each are top observers within Jordan across the country and in places like the Dana Biosphere Reserve, Jordan's largest nature reserve. Severeal other top observers such as @harrisonlee07, @wildchroma, @paolaferruzzi, and @saysay123 have observations clustered near this reserve. @yairur is also in Israel on the map, but their Jordan observations are just along the border with the Golan Hights in the northwest corner of Jordan. Several top observers such as @denis_m have observations clustered in the coastal city of Aqaba.


The graph of observations per month had a peak centered on January 2017 and has been ramped up again in 2019.


@sammyboy2059, based inthe UAE, is the top identifier and leads in bird and mammal IDs. @ronf leads in plant IDs. @cliygh-and-mia leads in insect, herp, arachnid, and mollusk IDs. @ariel-shamir and @artem are other top identifiers lending their expertise from Israel and Armenia respectively.


What can we do to get more people in Jordan using iNaturalist? Please share your thoughts below or on this forum thread.

@cliygh-and-mia @ronf @yairur @fragmansapir @khaled5 @denis_m @harrisonlee07 @sammyboy2059 @ariel-shamir @artem

We’ll be back tomorrow in Jamaica!

Watchung Reservation, NJ Nature Walk- Plants

This week while at home for fall break I was able to take advantage of a gorgeous fall day and go to a reservation near my house. With fall weather becoming more prominent it was a little chilly walking through the trails in the more woodsy areas of the reservation, but when the sun hit it was a perfect temperature. There weren't a lot of other people when I went out in the morning, but I saw one family on another trail enjoying their time outside the same way I was. On my walk I was able to see tons of different organisms in the densely populated woods.With the coming of colder weather there are a lot of changing leaves, but there are also tons of leaves that haven't changed from their bright green color. I also didn't see very many animals or insects on the nature walk, which I was a little surprised about. I could hear birds in the trees around me, but didn't see anything except for one spider, some ants eating a berry, and a small chipmunk. Overall the experience was very enjoyable and once again relaxing as I just got to spend some time outside on a beautiful day.

Nature Walk 3: Plants

I was able to complete this nature walk during fall break in my home town. I did this nature walk at Burnt Hill Park and some of the surrounding streets. Although I have been going to this park since I was about 7 years old to play soccer, there were quite a few things that I had never noticed before. This nature walk allowed me to explore more of this park than ever before and truly appreciate all of the beauty that it had to offer. The weather was perfect, about 60 degrees and sunny, with a slight breeze. I got to see a great deal of biodiversity within the park. All of the leaves were changing colors and many of the plants were in full bloom. There was a wide variety of plants ranging from nonvascular to vascular to flowering. I got to observe trees with their leaves changing colors and the goldenrods in full bloom, as well as some ferns and other types of plants.

Ansel Adams' take on Yosemite National Park.

To Matthew Adams, Ansel Adams was simply his grandpa.
Growing up in Fresno, California, Matthew would spend time with him during short summer vacations in Yosemite National Park, where his grandfather taught photography workshops.

Walking in Nashville

Over fall break, I went to visit my friend in Nashville and decided to do my nature walk while I was there! We went to a green space next to the model of the Parthenon they have in Nashville and tried to find some wild plants. While I wanted to make sure the majority of my posts were of plants, I had to include one picture of a squirrel because there were so many of them on and around campus! In the park, there were many cool looking trees, including one that I photographed that swept down close to the surface of the water. It was a lovely sunny and 75, the perfect weather to explore nature with a friend in a new city!

Plant Nature Walk

This past weekend for fall break I went to visit my boyfriend at Florida Gulf Coast University down in Fort Myers, Florida. Saturday, he took me on a little campus tour and along the way I stopped to take photos of plants that I found. Even though he kept getting annoyed at me cause every-time I saw a plant I'd have to stop and take a photo of it, I really enjoyed our walk through campus. Of course, the weather was beautiful, sunny, mid-80s, and a whole lot warmer than back in the northeast. There were several different plants that had grown around campus, and my personal favorite were the palm trees.

Outstanding October butterflies in Manhattan

Though we are now well into autumn, butterfly season is not over in Manhattan, and a few finds in particular so far this month demonstrate the value of staying alert.

1. Funereal Duskywing

On Oct. 10, @kasimac took a photo of an unusual-looking butterfly that turned out to be New York state's first record of Funereal Duskywing (Erynnis funerealis), a southern species that is known to wander widely: https://www.inaturalist.org/observations/34169876

2. Harvester

Early this month @spritelink photographed a Harvester (Feniseca tarquinius) in Central Park: https://www.inaturalist.org/observations/33778666. This species is the only U.S. butterfly with a carnivorous larval stage; the caterpillars eat aphids. Apparently there have been only two other sightings in Central Park in the last 25 years or so.

3. Horace's Duskywing

Not on par with the previous two observations but apparently rather rare nonetheless was a duskywing I photographed in Central Park, now identified as Horace's Duskywing (Erynnis horatius): https://www.inaturalist.org/observations/33932164.

Have fun out there!

PLANTS

I went on a walk today around a drainage pond behind my home in the woods of New Hampshire. Because of the October weather, the view was spectacular, filled with bright red and mellow orange leaves. However, with the theme of plants, all the plants seemed to be either dead or losing their leaves. I knew that I needed to stay low and take my time to find any surviving plants. Staying closer to the water yielded more success, all while providing a better view. Waling around the base of a connecting river caused me to find a wide variety of animals, like the frog in this post. I also found a rather large spider that caused me to run in the other direction, which sadly means there is no picture of the beast. The weather was great as the sun was out in a cloudless sky, as I roamed comfortably in a t-shirt. It was a great walk that led to me really observe all the plant life. Bonus: I saw a beaver from a distance!

Visit to Houghton Park and Hammond Pond

Today, I went to Hammond Pond and the surrounding trail to see if I could spot some fascinating plants. Not going to lie, but I was quite unsuccessful in finding anything interesting. First of all, there were too many boulders around and so I kept getting distracted by climbing them and second of all, I didn't manage to see anything that really popped out. However, I do have some other plants to show from my trip to Houghton Park. I went one week before in the afternoon when it was chilly 53 C°. Surprisingly, I found so many types of berries when I was walking around. I had a really bad urge to eat them, but I think most of them were poisonous. I saw some other flowers and weeds that were colorful and took some pics of those as well. One more thing, I know it's off topic, but I found a ton of fungi today as well! So, I've posted those on this journal just for fun.

Wheke of Otaipango Tries Photography

After taking photos of this wheke it decided to get in on the act and grabbed my camera. A good thing I had the cord around my wrist as it has a very strong pull. Pulling out my other camera I got this photo showing the wheke with my main camera and the grey cord you can see stretched tight is attached to my other wrist.

As I had someone with me, they took the cord of the camera the wheke had, then I got down to get some photos with the other camera. The wheke initially had the camera upside down.

Once it had sorted out which was was which, it thought to try and take a photo of a human, not a common species seen regularly by the wheke.

However, distracted by it's good looks, it forgot to press the button.

So the first wheke photographer of Otaipango did not get any photos.

Meanwhile in Wellington in April 2000 this wheke stole a camera while it was recording and from that video we can see it is the same species. I am not sure if these 2 are related, and I am not sure if there is any research into kleptomania and octopus. Is it just this species that has a fascination with photography or are there other species as well?

How common are bats with rabies and should you worry?

Bats can have rabies, but it is extremely rare for that to impact humans.

The chance of getting rabies from a bat is very small — the Centers for Disease Control and Prevention says there are one or two cases a year in the U.S. But bats are the most common source of human rabies in the United States.

Nature Walk: Plants

I went for a walk in the woods by Sucker Brook in Oxford, MA today. It was very pleasant outside in the 50's and quiet and calm. There were many of the same species of plants, so my observations have captured some of the abundant types of plant species/what I found most interesting during my walk. I am not certain whether I observed two types snowberries: one fruiting and another non-fruiting. I was also excited to find a moss species because we had talked about them this past week in lecture and it made sense that it was growing in a moist environment near a river. In addition, I noticed that the fern did not have spores on its underside at this point during its life cycle.

How to help identify ILBBY observations

Short version: Log into iNaturalist and go here! Click one of the photos to view more details and add or confirm an identification.

Long version: No observation makes it into the Illinois Botanists Big Year (ILBBY) or gets passed on to the Global Biodiversity Information Facility (GBIF) without at least two identifications. Making IDs is a great way to learn, see the diversity of species found in an area, contribute to science, and get to know other naturalists out there observing.

The Identify page on the iNaturalist website makes IDing really streamlined, especially once you start using the keyboard shortcuts. You can access the Identify page from the website by clicking the Identify link in the main header. Then click any image to view it in the "pop-up" modal in order to view the photos larger, add an ID, or see other details. There is unfortunately no similar quick and easy way right now to add identifications from the apps, so it's recommended to use a laptop or desktop computer.

Check out this useful video tutorial for using the Identify page on the iNaturalist website:

Here is a URL filtered to identify plants in Illinois observed in 2019: https://www.inaturalist.org/observations/identify?iconic_taxa=Plantae%2Cunknown&order_by=random&place_id=35&year=2019 I recommend bookmarking it so that it's easy to access. You can use the filters on the Identify page to show exactly the type of observations you're interested in.

Even a broad identification can be really helpful. So if you know it's in the aster family (Asteraceae), but not which species exactly, you can add an ID at family level. That way people looking to help ID observations in that family can find it easier.

Have questions about making identifications on iNaturalist? This Identification Etiquette post answers a lot of common questions. You can also ask below or start a new topic on the iNaturalist Forum.

Groton Town Forest

Today I went for a walk in the conservation area behind my house. I’ve grown up with these woods behind my house and am very familiar with the paths. However, I didn't realize how little I knew about the plants that were back there. Besides the major types of trees - pine, oak, maple, etc. - I had no idea what the plants were called or how diverse the forest was. One plant that I had noticed before but not known what it was was the sassafras tree, pictured below, that has very uniques leaves. I also had never noticed how many different kinds of mosses there were. Although they are not all pictured, I had never noticed the differences between the types of mosses until looking at them more closely on this walk. The weather was almost perfect, partly sunny and ~65 degrees with very little wind.

2019 ahead of 2018 for total observations!

Congrats ES 193CS + CCBER bioblitzers - this year's bioblitz has more total observations (798) compared to 763 for the 2018 bioblitz! That's an accomplishment especially since it is so dry this time compared to last year and many plants were dormant or annuals hadn't grown yet.

We'll wait to see the number of species observed as crowd-sourced IDs start coming in.

Sphaeroma quoianum (I) the larger isopod, among barnacles and in empty barnacle shells on the sides of large rocks (on 10/5) and on undersides of smaller rocks (9/14 & 10/5); usually with a double row of 4 bumps on its tail segment; this spices sticks out the small limbs alongside its tail segment ("uropods") when it rolls up into a ball
Gnorimosphaeroma oregonense (N) the smaller isopod, on the undersides of rocks; often with a broad, gray stripe along its back; does not stick out the small limbs alongside its tail segment when it rolls up into a ball (9/14 & 10/5)
(Discussed: Iais californica (I) commensal on the underside of Sphaeroma quoianum)

Scuds, Sand Fleas (Amphipoda)
Unidentified amphipod in the suborder Gammaridea - underside of a rock (9/14)
Skeleton shrimp - on dock sides; these are highly modified amphipods in the family Caprellidae (9/14 & 10/5)

Crabs & Shrimp (Decapoda)
Pagarus sp. Hermit Crab (N) in an Oyster Drill shell, on rocks (9/14)
Palaemon macrodactylus (I) one found among dock fouling; Asian shrimp thought to be from Korea based on its discovery in the Bay around the time of the Korean War (10/5)

Bryozoa
Conopeum tenuissum? - small colonies of an encrusting, membraniporine bryozoan that may be this species, on organisms attached to dock sides (9/14 & 10/5)

Sea Squirts (Tunicata)
Molgula manhattensis (I) very abundant on the dock sides (9/14 & 10/5)
Ciona savignyi (I) I saw one that was dound on the side of the docks (10/5)

Fish
Tridentiger sp. Goby (I) on mud (10/5)

Marsh Plants (I've listed the typical zonation pattern, but this may be less apparent in the small bits of recently-created brackish marsh at Lake Merritt)
Baccharis pilularis Coyote Bush (N) - high marsh/dry land transition (9/14 & 10/5)
Grindelia stricta Gumplant (N) - high marsh and slough levees (9/14 & 10/5)
Distichlis spicata Salt Grass (N) - high marsh (9/14 & 10/5)
Limonium Marsh Rosemary or Sea Lavendar (N) - high marsh (9/14)
Salsola soda Mediterranean Saltwort (I) - high marsh (9/14 & 10/5)
Jaumea carnosa (N) - marsh plain (9/14 & 10/5)
Sarcocornia pacifica (formerly Salicornia virginica) Pickleweed (N) - marsh plain (9/14 & 10/5)
Frankenia salina Alkali Heath (N) - marsh plain (9/14 & 10/5)

Birds of Note
Canada Geese and Mallard Ducks (9/14 & 10/5) On 10/5 discussed the biological, morphological, genetic and ecological species concepts; on 9/14 & 10/5 discussed Dave Wilcove's concept of Canadoids and Mallardoids, and Dave Covel's introduction of Canada Geese to Lake Merritt.
Double-crested Cormorants (9/14 & 10/5) On 9/14 we had the lovely experience of watching a comorant swim around underwater in front of us searching for a snack as gobies scattered before him; and discussed observations in the 1940's of regular "team fishing" by enormous flocks of comorants in San Francisco Bay between Berkeley and Emeryville.
Great Egret (9/14 & 10/5)
White Pelicans (9/14)
Coot (10/5)

Some Other Discussions
California Ridgway's Rail (former name: California Clapper Rail, which I still tend to use) interactions with the Atlantic Ribbed Horsemussel. (9/14 & 10/5)
The interactions of Saltmarsh Song Sparrows and Marsh Wrens in non-native cordgrass marsh. (9/14)
Clam shell anatomy; the size of the pallial sinus as an indicator of a clam's ecology (depth in the mud and types of predators); and why the native clam Cryptomya californica is typically found at depth despite its small pallial sinus. (9/14 & 10/5)
The recent and ongoing extirpation of the native mudshrimp by a non-native bobyrid isopod parasite; and how the arrival of a non-native mudshrimp may eliminate any density-dependent restriction of the parasite's impact on the native mudshrimp population. (10/5)
My hypothesis that marine avian schistosome populations are sustainable only at sites where both the snail host and the primary avian host are present in great abundance, and may be spread to temporary, secondary sites by the bird hosts. In the case of San Francisco Bay's two swimmer's itch outbreaks at Crown Beach in Alameda, the main populations may have been at the Lake Merritt bird sanctuary, where both water birds and snail hosts are abundant, and exported by commuting birds to create a secondary population at the beach where people regularly wade in the water and are exposed to the cercaria. (10/5)

Plants Nature Walk (Reservoir)

I thought that finding just plants somewhat dull, so I tried to spend some time looking for a few other organisms. Though, to be fair, the plants I did come across were interesting. I noticed that on some trees, the leaves were already changing colors, perhaps due to the recent cold weather. However, my walk around the reservoir was actually quite warm and pleasant. There was an abundance of small chipmunks and squirrels running around, gathering the nuts that littered the ground. In the middle of the walk, I found a few small arachnids, clinging to my clothing. I had taken a small rest on a bench, and noticed a small red mite on my pants. A few minutes later, a spider appeared on the bench next to be. It was tiny. I also realized I was starting to have a runny nose and puffy eyes, likely due to the pollen being released all around me.

Brazos Bend SP, Cool Autumn

After a night of yard-camping in the glorious new autumn temps (from 90's to 60's), Scott and I decided to go for a long nature walk at our favorite state park. Here are some of the species I logged into iNat. There are a few insects that required a slow-mo scrub (I didn't bring the Tamron 600mm with me this time), and I may upload later if I can figure out the ID's.

In going through list, I can see I missed several bird species which I typically ignore when looking specifically for autumn migrants (think mockingbird, cardinal, titmouse), those that only pass through on their way south. If I was also counting species and individuals on eBird, I would not have done that.
