Harris Hawk

Description:

This medium-large hawk is roughly intermediate in size between a peregrine falcon (Falco peregrinus) and a red-tailed hawk (Buteo jamaicensis). Harris's hawks range in length from 46 to 59 cm (18 to 23 in) and generally have a wingspan of about 103 to 120 cm (41 to 47 in)[5][6] They exhibit sexual dimorphism with the females being larger by about 35%. In the United States, the average weight for adult males is about 701 g (1.545 lb), with a range of 546 to 850 g (1.204 to 1.874 lb), while the adult female average is 1,029 g (2.269 lb), with a range of 766 to 1,633 g (1.689 to 3.600 lb).[7][8] They have dark brown plumage with chestnut shoulders, wing linings, and thighs,[9] white on the base and tip of the tail,[10] long, yellow legs and a yellow cere.[11] The vocalizations of the Harris's hawk are very harsh sounds.[5] —Wikipedia

Habitat:

Harris's hawks live in sparse woodland and semi-desert, as well as marshes (with some trees) in some parts of their range (Howell and Webb 1995), including mangrove swamps, as in parts of their South American range.[14] Harris's hawks are permanent residents and do not migrate.[13] Important perches and nest supports are provided by scattered larger trees or other features (e.g., power poles, woodland edges, standing dead trees, live trees, and boulders, and saguaros).[15] — Wikipedia

Notes:

The Harris's hawk is notable for its behavior of hunting cooperatively in packs consisting of tolerant groups, while other raptors often hunt alone. It is the Harris's hawk's intelligence that leads to its social nature, which results in easier training and has meant that Harris's hawks have become a popular bird for use in falconry. — Wikipedia
