Hawk ID

I'm finding it hard to ID with the yellow on the beak and the brown chest. Reminds me of a Red Tail but.... Taken just outside West Yellowstone, Montana.

Looks like a Swainson's Hawk, Ed. the chestnut bib is a good mark for a perched bird.

Agree with Swainson's - also look at the belly band below the buffy chest bib..... A roughlegged hawk would have a slimmer profile without the belly band. Also look how the outside tail feathers square off on the edges (birds right retrices). Great picture !
