Gray hawk

Buteo plagiatus

The gray hawk (Buteo plagiatus) or Mexican goshawk is a smallish raptor found in open country and forest edges. It is sometimes placed in the genus Asturina as Asturina plagiata. The species was split by the American Ornithological Society (AOU) from the gray-lined hawk. The gray hawk is found from Costa Rica north into the southwestern United States.

The gray hawk is 46–61 cm (18–24 in) in length and weighs 475 g (16.8 oz) on average. The adult has a pale gray body, the tail is black with three white bands and the legs are orange. It is a solid, unpatterned gray on the upper parts.

Immature birds have dark brown upperparts, a pale-banded brown tail, brown-spotted white underparts and a brown streaked buff head and neck. This species is quite short-winged, and has a fast agile flight for a Buteo. The call is a shrill whistled kleee-ooo.

The gray hawk feeds mainly on lizards and snakes, but will also take small mammals, birds and frogs. It usually sits on an open high perch from which it swoops on its prey, but will also hunt from a low glide. The nest is of sticks and built high in a tree. The usual clutch is one to three, usually two white to pale blue eggs. The young take about 6 weeks to fledging.

The gray hawk averages 46–61 cm (18–24 in) inches in length and weighs 475 g (16.8 oz). This bird has a relatively shorter wing span, but a long tail compared to the red-tailed and red-shouldered hawks. It has broad rounded wings, a hooked beak, and yellow legs. Thompson, L. (1995–2013). It is very distinctive from its smooth pale gray plumage. The tail features are in a horizontal striped pattern in a white-gray-white pattern with white at the tips of the tail feathers. The tail feathers have two white bands with one being wider than the other. The sexes are similar in coloration. The adults, both male and female, have a darker gray top side with a lighter gray and white underside. The juveniles have a dark brown topside and a streaked or spotted underside and the tail feathers have numerous dark bands. The juveniles have very obvious bold facial strips and white upper tail coverts, which are the feathers at the base or start of the tail. The juveniles also have a different plumage color due to dominance and they use the dull color for camouflage.
