Raptor Species
Red-shouldered Hawk
Buteo lineatus
Taxonomy:
Class: Aves
Order: Falconiformes
Family: Accipitridae
Subfamily: Buteoninae
Genus: Buteo
Length: 15-19 in.
Weight: 1.1-2 lbs.
Wingspan: 37-42 in.
Common Names: red-bellied hawk
Etymology: buteo (Latin) - "a kind of hawk"; lineatus (Latin) - "striped"
Description: Adult red-shouldered's breast is rufous with fine horizontal
barring, tail is black with 3-4 narrow white bands. Immature's breast is light with dark brown vertical
streaking, tail is dark brown with many fine light brown bands. The red shoulders (actually the wrist of
the bird) are difficult to spot at a distance. Red-shouldered hawks have longer tails than
red-tailed hawks. Iris
darkens with age and cere becomes less greenish and more yellow. They have four notched primaries.
Flight: Active flight is accipiter-like with 3-5 quick, stiff shallow wing
beats, then a period of glide. They soar with wingtips slightly drooping, and do not hover.
Voice: A loud, screaming "kee yar" dropping in
pitch, typically uttered 2-4 times. Red-shouldered hawks are quite vocal (blue jays frequently mimic
their call), especially during spring courtship.
Habitat: They inhibit denser woodlands than the
red-tailed hawk,
preferring swampy lowlands or woods around streams and rivers. Development by humans tends to decrease
habitat for red-shouldered hawks and create open areas preferred by red-tails. Red-shouldered hawks are
more difficult to spot perched lower in trees; in winter they perch in the open more often. They will
commonly nest in suburbs.
Distribution: Fairly common east of the Great Plains, northern birds are
migratory. Pesticides probably reduced populations, but loss of habitat is most likely the cause of
any long-term decline. Red-shouldered hawks are of special concern in North Carolina.
Nesting: Make their nest of sticks, often returning to the same territory for
many years. They usually construct a new nest each year but may refurbish a nest from several years ago.
Red-shouldered hawks build their nests lower than the
red-tailed hawks, at about
half way up the tree. Often line nest with greenery (possibly to repel parasites). Lay 2-4 eggs,
incubation is about 33 days and is shared by both sexes. Young fledge in 5-6 weeks (45 days on average).
Breed at 2 years, nest usually spaced .67 to 1.3 miles apart along rivers.
Food: Small mammals, birds, frogs and toads, snakes and lizards, and occasionally
crustaceans, fish and insects.
