Ferruginous hawks ??? (pictures)

A strong clue to the ID of these young hawks is that the tarsi are feathered or "rough." The old name for Ferruginous Hawk was "Ferruginous Rough-leg." (Ref: Peterson, 1941)

Great photos! Thanks.

Bill and Joe,

Since the tarsi are not feathered, it's not a Ferruginous Hawk. Ferruginous, and Rough-legged, have feathering all the way down to the feet.

This is an immature Western Red-tailed Hawk. Classic heavily marked belly-band, streaked throat, and short gape (note that on Ferruginous, the gape extends back to the rear end of the eye). Ferruginous would also have much more white in the spread wing.

Cheers,

Hi Bill:

At such close range, Ferruginous Hawks show their eagle-like gape,
which extends all the way under the eye. These birds are all juvenile
Red-tailed Hawks. Juvenile Ferruginous Hawks, unless they are dark
birds, have white throats and not so much dark below.

Enjoy,

Tony

I think these pictures are all of immature ferruginous hawks that i
have
seen recently around Colorado Springs and Falcon but I am not really
sure.

Please send me any comments

Thanks
