Bob took these photos at the Boyce Thompson Arboretum during the Bye – Bye Buzzards event.

These are Turkey Vultures…

Amy Burnett has identified the birds below as follows…

Harris Hawk:

Peregrine Falcon:

American Kestrels.  The male, on the left, has more blue than the female on the right.

Red-Tailed Hawk, both photos, below.  (Amy says she is not certain about the last one, but I think it’s just another shot of the same bird in the photo immediately below.)
