Galapagos Hawk vs Hawaiian Hawk

Galapagos Hawk (Buteo galapagoensis)

Galapagos Hawk

Buteo galapagoensis

Large1.1 kgWoodland

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".

Buteo solitarius

Large501 gForest

The Hawaiian hawk measures approximately 40 to 46 centimetres (16 to 18 in) in length. The female, which weighs 605 g (21.3 oz) on average, is larger than the male, which averages 441 g (15.6 oz). Two color phases exist: a dark phase (dark brown head, breast, and underwings), and a light color phase (dark head, light breast and light underwings). Feet and legs are yellowish in adults and greenish in juveniles. During breeding season one of the pair, possibly the female, has a distinctive yellow forecap area just above the upper mandible.
