Folks...

Not sure about this one.. taken in August in Yellowstone National Park. I have more images, but none are available at the moment. If I need to post the others, simply request and I'll do that over the weekend.

Thanks in advance for the help!

If you could post more shots it would be appreciated. It might be a dark morph juvenile Rough Legged Hawk, but would need a good look at those legs from a different angel. The patagial patch looks good, but not difinitive. A view of the chest area might help as well.

Okay.. more images to come

When I have a moment.. either later today or over the weekend, I'll be sure to get more images up.

I can also clean up the posted image... so perhaps I'll just start a new thread when the material is ready.

Looks to me like a subadult Ferruginous Hawk, dark morph. The feathered tarsi rule out plenty of other species (excepting Rough-legged), but the underwing pattern does match Ferrug. It's less contrasty than is usually found with Rough-leg.

Also, August is still pretty early for Rough-leg in that area.

I'm wondering, in what part of the Park did you see this bird? I know of a breeding location within 50 miles of Yellowstone, but that is in Idaho, in lower-elevation sage flat habitat.

Specifically, there is a 4x4 trail not far form the petrified tree. I followed that road to the top... I would estimate about 8.5-9K feet up... and there he was hanging out. So.. basically around the Petrified Tree area.

I would have to look at a map to be more specific which I don't have in front of me at the moment.

Thanks for the thoughts.

I don't see feathered tarsi, the lower legs look unfeathered to me

Here's some ferruginous pictures

I think ferruginous lack detail under the wing.

Hi all.

Ferruginous Hawk has feathered legs all the way down to the toes. It also has a different wing formula - narrow wings especially the hand, larger feet and different pattern on the underwing in dark birds.

Note the primary tip pattern and the pale crescent inside the dark tipped primary coverts:

Check some of these Red-tailed Hawks - which I think JTK,s bird is.
