(below, here is a light form, or morph as some will call it)
(above) Light Form Ferruginous Hawk. They often perch on the ground like Northern Harriers and Rough-legged Hawks. These hawks have been seen running along the ground in pursuit of prey. Also notice this birds light colored head and its bellyband-less front.
(below) the dark form in flight, tricky against RLHA's and RTHA's
Main thing here for field work against other "hawks" is the only other two Dark Buteo species in the region right now would be Red-tailed and Ferrruginous hawks, and both have a vastly different tail, silhouette and head. If you like me to elaborate more please let me know. thanks larry.
Lots to talk about here. Amazing....Zach has documented quite a few raptors in our region, these photo's represent some of Feralzach's latest work. We are very lucky to have people out in the feild to capture our rare hawks on film and document where they are and what they need to survive, i.e. habitat and prey.
