The Ferruginous Hawk (Buteo regalis) is a large hawk (56-69 cm [22-27 in] long; 133-142 cm [52-56 in] wingspan) with two color morphs. The light morph has white underparts and rusty legs that form a 'V' when the bird is soaring. The upperparts are rusty and it has a pale head. The rarer dark morph is dark brown except for the underside of the flight feathers on the wings. It hunts for rabbits, hares, ground squirrels, prairie dogs (Cynomys spp.), and pocket gophers. It breeds throughout much of the western US and winters from California east through the Great Plains and south into Mexico. The Ferruginous Hawk will experience a high degree of climate exposure and has a high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Ferruginous Hawk’s climate change vulnerability is impacted by factors related to movement and life history, which influence its ability to shift in space and persist in place. It also has documented or modeled responses to climate change that impact its vulnerability score.
