Moose Alces alces

Observer

Date

October 1, 2019

Description

We saw 1 cow moose browsing on willows at the Caribou Ranch beaver ponds. Not that easy to see in today's low light and all the intervening vegetation.

No sign of calves, so they may have already dispersed. Always be wary around moose, especially cows in summer - who will defend their calves.

Bullsnake Pituophis catenifer ssp. sayi

Observer

Date

June 3, 2019

Description

Driving down with the caretaker and came across this 'mating ball' of bullsnakes. Also encountered a single bullsnake the next day on the road. They are a reminder to keep to the speed limit on our roads - it keeps the dust down, is safer for those on bikes, and gives you time to stop or brake for wildlife on/adjacent to the roads.

I should also post the swallowtail that is in the upper part of the photograph!

Just a coyote in the pasture adjacent to 75th Street. One strong argument for dogs on leash and no outdoor cats.

Description

I was opening the gate to get back to the back ponds at Walden Pond and saw this owl. Look how wide the wings are - that contributes to the maneuverability and quiet that makes them such stealthy hunters.

Elk Cervus canadensis ssp. canadensis

Observer

biologistdave3

Date

October 2, 2018

Description

We were doing an official count of the North Boulder Elk Herd with Colorado Parks and Wildlife. We knew there were elk up in this vicinity but we couldn't see them from the highway. I drove up toward Rabbit Mtn and glassed back to this slope - and saw 60.

An hour later we were counting 260 basking in the sunshine above the busy Foothills Hwy. This area is part of the Red Hill Conservation Area and closed to the public. It is a diverse, high quality habitat with rare combinations of plains, foothills, and montane species.

These animals are why the speed limit is lower - be careful driving US36 north of Boulder at night/bad light. Lots of deer and elk cross the road. Please slow down and be safe.

American Kestrel Falco sparverius

Observer

Date

November 27, 2018

Description

We had to 'rescue' a kestrel from inside our shop at Parks HQ. It ended up bumping into a window and getting stunned. We released it in the adjacent field where we see them hunt all year. The male of the pair even did a fly-by. After about 30 minutes the bird was able to fly away.

Common Nighthawk Chordeiles minor

Observer

Date

June 26, 2018

Description

We flushed what I think would have been a Common Nighthawk off her nest at Rabbit Mountain. We stopped immediately so as to not step on her cryptic eggs. Did you find them (2) left of the knife? There are but a few birds that nest in the open on bare ground as it is a very risky strategy 'hiding in plain sight.'

American Dipper Cinclus mexicanus

Observer

Date

June 27, 2018

Description

One little dipper darting along Fourmile Canyon Creek at Anne White open space. This property is still closed, as there is no parking lot and heavy construction along the access roads (Lee Hill & Wagonwheel Gap). We were in there with Boulder County Youth Corps working on removing noxious weeds.

Difficult to see in some of the photos. That is nature's design. Cryptic to predators and cryptic to prey in the water.

nice big snapping turtle on the trail between Wally Toevs Pond and Cottonwood Marsh. It had just come up the bank from Wally T and was heading into CW Marsh. It's head was the size of my fist. Something primeval about seeing it trudge across the trail. very cool!

Elk Cervus canadensis ssp. canadensis

Observer

Date

June 6, 2018

Description

We went to work on building our exclosure on Rabbit Mtn and walked up to a week-old elk calf! Their defense mechanism for this time of life is to hold, hold, hold. We moved away and it never got up.

We didn't see it for at least 30 seconds - 5 of us! I only took the 1 photo and edited a zoomed in version. The elk is laying down, facing us, head turned to the right. Spots visible. Note the tiny onion in the sun left of the elk.

Saw a coyote off in the trees a couple of times. One time with something big in its mouth. Was it a pup (moving it)? Was it a turkey? Nope - It was the chest wall of a yearling mule deer!

Date

March 24, 2018

Description

Our training group found a raccoon skeleton. I figured I would post a skull photo just to show teeth and jaw. As a carnivore, you can see the large canines and sharp-ridged molars - for catching and eating prey. Quite a scary look compared to the normal 'cute' image of a raccoon.

Mule Deer Odocoileus hemionus

Observer

Date

February 7, 2018

Description

Small group of mule deer along the Carter Lake Canal. We saw deer most mornings as we were trapping elk. And luckily we didn't trap many of them in our efforts. These animals 'enjoy' this habitat west of the mine that is closed to the public. It is really valuable to have areas that are relatively wild, without the influence/presence of man.
