Identification

Waterford, New York, USA, January 2010

Adult: Length 48cm (19in). Wingspan 125cm (49in).
A large, stocky hawk with a whitish breast with dark band, usually rusty tail, and dark leading edge on wing (patagial mark -- seen during flight).

This species is quite variable in colour, especially in the western U.S., where blackish individuals occur; these often retain a rusty or reddish tail. One of the most diagnostic field marks is the "cumberbund"; an area on the middle breast that is usually streaked darker than the rest of the underbody.
Immature: Duller, more streaked, and light brown tail with some dark barring.

Variations

Krider's Hawk (subspecies krideri) is a pink-tailed type from the great plains.

Similar Species

  • Swainson's Hawk has darker chest, less stocky build, and narrower, more pointed wings. However, Harlan's Hawk, harlani, a very dark morph easily confused with the Swainson's Hawk.

Distribution

Subspecies

There are 14 subspecies[1]:

Two additional subspecies: suttoni, and lucasanus are not recognised by all authorities[2].

Harlan's Hawk (subspecies harlani) has in the past been considered a separate species, and proposals have been put forward to adopt that treatment again.

Habitat

Subspecies harlani

Marlin, Falls County, Texas, USA, February 2019

The most common hawk on the North America continent, B. Jamaicensis frequents woodland edges, soars above plains, and is often seen perched on utility poles where natural perches are not available.

Behaviour

Diet

Soars or perches, looking for a wide variety of food; small to medium mammals, lizards, frogs, worms, insects, bats, and small birds.

Breeding

Monogamous. They construct a stick nest in trees or cliffs.

Conservation Status

Common and plentiful, some decline due to habitat loss, although it adapts relatively easily to new environments, even urban. Many are still shot illegally for amusement.
