Buteo platypterus
At a Glance
The Broad-winged Hawk is a small hawk, common in eastern woodlands in summer. Staying around the edges of forest, the Broad-wing Hawk is often not very noticeable during the breeding season, but form spectacular concentrations when they migrate. Almost all individuals leave North America in the fall, in a mass exodus to Central and South America, and sometimes thousands can be seen along ridges, coastlines, or lake shores when the wind conditions are right.

Range & Identification
Migration & Range Maps
A long-distance migrant, most going to South America for the winter. Migrates in flocks called "kettles". Birds from throughout the east travel southwest or south to go around, not across, the Gulf of Mexico.
Description
Sexes similar — Length: 13–17 in (33–44 cm); wingspan: 2 ft 8 in–3 ft 3 in (81–99 cm); weight: 9.3 oz–1 lb 3.8 oz (265–560 g). The Broad-winged Hawk is a chunky and compact raptor, it soars with wings held flat and tapering to a point. The adult Broad-winged Hawk is the only eastern buteo with broad tail-bands with a dark back and reddish chest. The juvenile Broad-winged Hawk has narrow tail-bands (last one thicker) and dark blotches on side of white chest. On all, wings are pale or whitish below with dark tips and trailing edges. A rare dark-bodied morph occurs mainly in western part of range.

Habitat
Woods, groves. Typically breeds in deciduous forest or mixed coniferous-deciduous forest, often near water and near clearings or edges. Migrants may be seen over any kind of open country, but tend to stop for the night in forest or extensive groves of trees.

Behavior
Eggs
Usually 2-3, sometimes 1-4. Whitish, usually spotted with brown. Incubation is almost entirely by female, 28-31 days. Male brings food to female during incubation, then he may sit on eggs while she eats.
Young
Female Broad-winged Hawk remains with young almost constantly for first 1-2 weeks after they hatch; male brings food, and female feeds it to nestlings. Young may climb out of nest onto nearby branches at about 4-5 weeks; can fly at about 5-6 weeks, and soon start learning to hunt.
Feeding Behavior
Broad-winged Hawk hunts by watching for prey from a perch, usually located along edge of woods or near water. When prey is spotted, the hawk swoops down rapidly to capture the creature in its talons. Occasionally hunts by flying through the woods or along watercourses, actively searching for prey.
Diet
Includes small mammals, amphibians, reptiles, birds. Varied diet includes mice, voles, squirrels, other small mammals; toads, frogs, snakes, lizards, young turtles; various small birds; large insects. Sometimes eats crayfish, fish, centipedes, earthworms.
Nesting
Early in breeding season, Broad-winged Hawk pairs circle high in the air, calling. In display, one bird may fly high, then dive steeply toward the ground. Nest site is usually in the lower part of a large tree (either deciduous or coniferous), typically 25-40' above ground. Nest (built by both sexes) is a rather small platform of sticks, lined with softer materials such as bark and moss. Leafy green twigs often added during nesting cycle. Often uses pre-existing nest of hawk, crow, or squirrel, adding material to it.
Conservation
Conservation Status
Early in the 20th century, large numbers were sometimes shot during migration, but with legal protection their numbers now seem healthy. The Broad-winged Hawk is still hunted in its southern range and human development threatens gains made in the East of its range.
