Working on the Teton Cougar Project
July 28, 2013 by Connor O'Malley
I’ve been volunteering with the Teton Cougar Project for a week now and have already seen 12 kill sites, many beds, and hiked over 40 miles. Its been intense! But I’ve learned a lot and seen a ton of cool stuff. Here are some pictures…

Big mule deer cached by F109, one of my favorite cats.

Road-killed grouse foot.

Dr. Elbroch has an amazing track cast collection.

Cliff swallow egg.

Badger hole.

Pronghorn foot.

Pronghorn killed by M68.

Track of M68. We just returned from a 4 day road trip finding all of the recent kills from dispersing young male, M68.

Here is where M68 sat and looked out for miles into the desert sagebrush, from the top of a ridge.

Michelle, standing near one of M68’s bedding areas.

Little rock overhand where M68 bedded. From here he had an endless view into the sagebrush desert.

Full moon in the desert.

I’ve always wanted to find where a cougar scratched a log… here it is! They do this to stretch, sharpen their claws and maybe scent mark too. They are just big house cats.

Close-up of the scratch. You can see some hairs stuck in there too.

View from one of M68’s beds.

A recent burn where M68 hunted for a couple days (unsuccessfully). There was a ton of deer and elk sign in here though.

Uinta ground squirrel tracks.

Badger tracks.

We use the teeth to record what age the deer was that was killed. This is the jaw bone of a yearling mule deer.

Bears foraging, flipping over rocks.

Hiking back from one of M68’s kills.

Magpie cough pellet.

Snowshoe hare killed by a cougar. Amazing how the skull is perfectly skinned.

Here a woodpecker pecked into the bark to reach a grub.

The remains of a fawn killed by a cougar.

Fresh wolf tracks.

Back to the Tetons and back to studying our local cats. This was a nice moment from my drive home from the office the other day. Beautiful landscapes full of wildlife seem to be everywhere here.

So awesome! Thanks for sharing some of your finds and experiences Conner. What an amazing adventure you and Michelle are on right now. Keep the pics coming. Peace.
Connor-Great photos! Sounds like you are having fun.
I was talking with a friend of ours who is a well known bear biologist from University of Tennessee (Mike Pelton). He was asking me who you are working with because he might know him. Also the name of the main cougar guy -the one you wrote to as a child.
Say hi to Michelle.

Hi Aunt Marilyn,
I’m working with Mark Elbroch. The biologist I wrote as a kid was Maurice Hornocker. I’ll ask Mark if he knows Mike Pelton. Hope you and Urbie are having a good time – I still need to get that reel back to him.

There are awesome pictures, Connor! I am glad to you 2 are having a good time in the Rockies. How amazing to get to experience such intimate views into the lives of these big cats.
Your Cooper’s Hawk foot looks like a grouse. Cooper’s hawks have bare shins, with yellow feet and legs. I also see camber in those primaries in the same photo, and no noticeable slotting.
Great stuff, keep posting your finds!
Hey Fil,
I’m not sure what that bird was… you’re right it couldn’t have been a cooper’s hawk since it doesn’t the yellow legs but it was definitely an immature raptor of some kind. Maybe a prairie falcon?? Unfortunately I only took pictures of the feet and not the whole bird… typical.
Great pics as usual. Would like to know if there are any patterns in Cooperhawk pics that allow identification. 2) What kind of clothing are you packing during your time in the desert? 3) On the woodpecker picking at the tree–was it something about the pattern that led you to believe that it was a woodpecker. It looks like just a chunk of bark was removed. How do you know it was a woodpecker? (Or did you deduece this because of the grub imprint?)
1) Unfortunately I have no idea what kind of raptor that is now that my cooper’s hawk theory is debunked. Leaning towards a juvi prairie falcon. 2) I wore shorts, t-shirt and sneakers in the desert… jeans or carharts when we had to thrash through willows or thick sagebrush. 3) The tree was covered with spots where the bark was removed… I thought it could have been a scratch post of a cougar but looking closely I saw tiny beak marks and then realized all the places without bark also had dust from a bark beetle larvae.
Connor,
Glad to see your new post. You guys are seeing some amazing stuff out there. So glad you are sharing the photos. I am really enjoying them, and can’t wait to see more.
Here are some images that might help sort things out your mystery bird feet:
Here is a ruffed grouse foot:

Notice the your mystery bird has pretty classic game bird feet, much like the photo above: small halix, even spacing between main toes, muscles on toes are flat (for walking) instead of bulging for gripping power. Toe one is especially small on the bird in your photo and the claw is teenie. Many birds of prey have their largest talon on toe 1.
Here is a Prairie falcon foot (Note the size of talons and much larger toe 1 (halix)):

Note the bare shins (almost all hawks, falcons and eagles have bare shins, there are only 2 that I know of that have feathered shins, Golden Eagle and Rough-Legged Hawk) on this prairie falcon:

Here is a nice Sooty grouse image showing the feet feathering:

Even with the foot aside, the feathers are pretty distinct.
Leading primaries in the image is a pretty good match for grouse, take a look at these 2:

Ruffed Grouse:

Here is Prairie Falcon for comparison:

And Cooper’s Hawk:

Anyway, hope that is helpful. If you have more photos of the kill site, I am sure we could figure it out for sure.
IDing carcasses can be difficult.
Encore un beau post que voila, merci à la prochaine
