SPECIES INFO

The Broad-winged Hawk, (Buteo platypterus), is a small hawk of the Buteo genus. During the summer they are distributed over most of eastern North America, to as far west as the Alberta province and Texas; they then migrate south to winter in the neotropics from Mexico down to Southern Brazil. Many of the subspecies in the Caribbean are endemic and most do not migrate.

Adult birds range in size from 34 to 45 cm (13 to 18 in), weigh from 265 to 560 g (9.4 oz to 1.2 lbs) and have a wingspan from 81 to 100 cm (32 to 40 in). As in most raptors, females are slightly larger than males. Adults have dark brown upper parts and evenly spaced black and white bands on the tail. Light morphs are pale on the underparts and underwing and have thick cinnamon bars across the belly. The light morph is most likely to be confused with the Red-shouldered Hawk, but that species has a longer, more heavily barred tail and the barred wings and solid rufous color of adult Red-shoulders are usually distinctive. Dark morphs are a darker brown on both upperparts and underparts. They are much less common than the light-coloured variant. Dark morph Short-tailed Hawks are similar but are whitish under the tail with a single subterminal band. The wings are relatively short, broad and have a tapered, somewhat pointed appearance unique to this species.

At all times, Broad-winged Hawks inhabit forested areas, with even migratory birds choosing only wooded areas to roost in. They are seemingly indifferent to the type of forest used either for breeding or wintering.

These birds hunt by sitting on a perch and watching for prey, and have been described as "cat-like" while stalking. When prey becomes apparent, they swoop down to the forest floor after it. Rarely, they will also fly in search of prey. The diet is variable, but small mammals, like rodents and shrews, are the most regular prey. More so than other North American Buteo hawks, amphibians, reptiles, insects and other invertebrates are thought to be important prey items. Birds up to the size of Ruffed Grouse (but usually much smaller) are also sometimes taken.

In the springtime, the breeding pair build a stick nest relatively low in a mature tree. The clutch can number from 1 to 5 eggs, but usually 2 or 3. The brown-spotted eggs are usually 49 39 mm (1.9 1.5 in) and weigh about 42 g (1.5 oz). The incubation period is 28 to 31 days, with the male doing most of the foraging while the female incubates. The semialtricial, 28 g (1 oz) hatchlings are brooded for 21 to 24 days. The young first leave the nest at 5 to 6 weeks of age, and linger around the nest site for up to 8 more weeks. Predators of eggs and nestlings include raccoons, crows, porcupines and American Black Bears. Predation of adults and immatures are not well-known, but they are known to fall victim to Great Horned Owls and Bald Eagles.

Broad-winged Hawks are long-distance migrants, except for the Caribbean subspecies. They travel in large flocks or "kettles" during migration. During days with favorable winds, enormous kettles of tens of thousands of Broad-wings can be seen along flyways.

Although this bird's numbers are relatively stable, populations are declining in some parts of its breeding range because of forest fragmentation.
