Red-shouldered Hawk
Red-shouldered Hawk
Buteo lineatus
At a Glance
A hawk of the woodlands, often heard before it is seen. The clear whistled calls of this hawk are conspicuous, especially in spring; in the east, Blue Jays often give a near-perfect imitation of this call. Over much of eastern North America the Red-shoulder has become uncommon, sticking closely to the remaining forests. Populations in Florida and California are often more visible, perhaps adapting better to open habitats.

Range & Identification
Migration & Range Maps
Mostly a permanent resident in west and south; northern birds migrate, but do not travel far. Some movement in winter as far south as central Mexico.
Description
16-24" (41-61 cm). W. 3'4 (1 m). Larger than Broad-wing, with longer wings and tail. Often flies with several quick flaps and a glide, suggesting the Accipiters. Adult striking: narrow black and white bands on flight feathers of wings and tail, reddish shoulders and chest. West coast birds redder, Florida ones paler, grayer-headed. Juveniles in east are browner, with narrower bars on tail. On all, note pale crescent near wingtip in flight.

Habitat
Bottomland woods, wooded streamsides, swamps. In east, nests in deciduous and mixed forest, with tall trees and relatively open understory, often along rivers and swamps. May move into more open habitats in winter. In west, typically in riverside forest or in oak woodland, sometimes in eucalyptus groves. Florida birds may be in pine woods, mangroves.

Behavior
Eggs
Usually 3-4, sometimes 2. Pale bluish-white, blotched with brown and lavender. Incubation is mostly by female, roughly 33 days. Male brings food to female at nest, and may take a turn sitting on eggs while female eats.
Young
Female remains with young most of time for first 1-3 weeks after they hatch; male brings food, female feeds it to nestlings. Young leave the nest at about 5-7 weeks after hatching, and are fed by parents for another 8-10 weeks.
Feeding Behavior
Usually hunts by watching from a perch, either within forest or in open, swooping down when it locates prey. Sometimes flies very low in open areas, taking creatures by surprise. May use hearing as well as sight to locate prey.
Diet
Includes small mammals, amphibians, reptiles, birds. Diet varies with region and season. Main items often mammals such as voles and chipmunks, at other times frogs and toads; may eat many crayfish in some areas. Also eats snakes, small birds, mice, large insects, occasionally fish, rarely carrion.
Nesting
In courtship, male displays by flying upward, calling, then diving steeply. Pairs may soar together in circles, calling, high over nesting territory. Nest site is usually in deciduous tree, sometimes in conifer, located in fork of main trunk or at base of branches against trunk, usually 35-65' above ground. Nest (built by both sexes) is platform of sticks and other material, lined with bark, moss, and sprigs of green vegetation. Nest may be reused for more than one season.
Climate Vulnerability
Conservation Status
Far less numerous than historically in some areas, including upper midwest and parts of Atlantic Coast, but current populations thought to be stable in most regions.
