Grey Hawk

Identification

The Grey Hawk is a compact raptor measuring 46–61 cm (18–24 inches) in length, weighing an average of 475 grams. Adults are strikingly distinctive with smooth pale gray plumage on the upper parts and lighter gray and white underparts. The tail is particularly diagnostic: black with three white bands in a striking horizontal striped pattern. Orange-yellow legs complete the adult's elegant appearance. Both sexes are similar in coloration. The Grey Hawk has relatively short, broad rounded wings and a long tail compared to larger relatives like the Red-tailed Hawk, giving it a compact silhouette.

Immature birds are quite different and often confuse observers. They display dark brown upperparts with heavily spotted and streaked white underparts, and their tail features numerous dark bands rather than clear white ones. Young birds also show bold facial stripes and white upper tail coverts. This dramatic plumage difference serves as camouflage during their vulnerable juvenile period. The species has a shrill, distinctive call: a whistled "kleee-ooo" that often betrays its presence.

Range & Habitat

The Grey Hawk's range extends from southern Arizona and southern New Mexico south through the southwestern United States, Mexico, Central America, and into northern Costa Rica. The species inhabits open country and forest edges, showing a preference for areas including river edges, savanna, agricultural land, and cleared areas. In its tropical range, the Grey Hawk favors dry second-growth forest, adapting well to human-modified landscapes alongside native habitats.

Behaviour & Diet

This agile predator feeds primarily on lizards and snakes, supplementing its diet with large insects, small rodents, frogs, and occasional birds. The Grey Hawk typically hunts from an open, high perch where it can swoop on unsuspecting prey, though it will also hunt from a low glide just above the canopy, particularly in brushy areas. Its short wings and long tail make it surprisingly nimble for a Buteo hawk, enabling rapid, agile flight through complex terrain.

The Grey Hawk is monogamous, building stick nests high in trees. The typical clutch consists of one to three eggs, usually two, colored white to pale blue. Young fledge in approximately six weeks. Migration patterns vary by geography: northern populations breeding in the southwestern United States migrate in spring and return south by mid-October, while southern populations tend to remain year-round residents, with only occasional individuals overwintering in southern Texas.

Best Time & Places to See It

Grey Hawks are most reliably encountered in open country and at forest edges throughout their range. Northern populations are present during breeding season (spring through early autumn), while year-round viewing is possible in Mexico and Central America. River valleys and agricultural areas adjacent to suitable forest habitat offer good viewing opportunities. Listen for the distinctive shrill "kleee-ooo" call, which often helps locate birds perched in open positions.

Photography Tips

The Grey Hawk's preference for open perches makes it more approachable than many forest raptors. The pale gray plumage of adults provides excellent contrast for photography, particularly in bright tropical light. Focus on capturing the diagnostic black tail with white bands and the orange legs. Photographing perched birds from a distance using a telephoto lens will yield the best results. Early morning light often illuminates perched birds beautifully, enhancing the subtle gray tones of their plumage. Patience in scanning open areas and forest edges will be rewarded with opportunities to document this elegant small raptor.
