Galapagos Hawk
Buteo galapagoensis
The Galapágos hawk is similar in size to the red-tailed hawk (Buteo jamaicensis) and the Swainson's hawk (Buteo swainsoni) of North America, but the size is variable across the islands as is recorded for many animals native to the Galapágos. They appear to be somewhat more heavily built than those well-known mainland species, and going on average weights, this species is the second heaviest Buteo in the Americas, behind only the ferruginous hawk. The Galapágos hawk can range from 45 to 58 cm (18 to 23 in) in length from beak to tail with a wingspan of 116 to 140 cm (46 to 55 in). Voice: The call of the Galapágos hawk is a series of short screams similar to the call of the red-shouldered hawk that has been described as a "keer, keeu," or an inflected "kwee". Especially noisy during mating season, their call softens to a "kilp, kilp, kilp".

White-throated Hawk
Buteo albigula
The white-throated hawk is 38 to 48 cm (15 to 19 in) long with an 84 to 102 cm (33 to 40 in) wingspan. Females are up to 20% larger than males and both sexes have the same plumage. Adults have a brownish black face and upperparts. Their tail has a dark brown upper surface and a grayish lower surface with up to 10 narrow dark bands. Their chin, throat, and underparts are white with brown streaking on the breast and belly and rufous barring on the thighs. Their eye is brown and their cere, legs, and feet yellow. Voice: The white-throated hawk is thought to be mostly silent. It does make a "squealing 'kee-ah' during breeding season".
