Sharp shinned hawk sounds12/16/2023 ![]() ![]() The Northern Goshawk has the heaviest sound, kak, kak, kak or kuk, kuk, kuk. These three accipitrine hawks are fairly similar in voice. In the adults of all three species the long feathers under the tail are snowy white, and the eyes have changed to dark red or orange red. The goshawk is similarly crossbarred below with grey, but these markings are so fine and so closely spaced as to appear a uniform pale grey at any distance. ![]() From below, the two smaller species appear tawny or reddish brown, due to broad, even crossbarring of this colour on a creamy white ground. In the adults, the upper surfaces from the nape to the tail, including the wings, are pale slate to bluish grey. Their eyes vary from pale grey to greyish yellow and from amber to amber-yellow.Īll young acquire adult plumage at two years. The pale breast and flanks are streaked lengthwise with dark brown, and the wings and tail are crossbarred with dark bands. The feathers of the back are broadly edged with white or near white and crossbarred with darker brown, giving the back a coarsely barred appearance. First year accipiters are always brown: sepia or chocolate brown above, pale tawny or yellowish-brown to creamy white below. In all three species the colour of the young birds differs strikingly from that of the adults. There are distinguishing characteristics-for example, the shape of the tail is square for the Sharp-shinned Hawk, rounded for the Cooper’s Hawk, and almost square for the Northern Goshawk-but identification is difficult. The Cooper’s Hawk is intermediate in size the male Cooper’s is easily confused with the female Sharp-shinned Hawk, and the female Cooper’s Hawk is almost as large as the male Northern Goshawk. They range in size from the small male Sharp-shinned Hawk, which is smaller than a gull, to the large female Northern Goshawk, which at 55 to 66 cm is larger than a crow. The female of each species grows larger than the male. In contrast, the wings of another group of hawks, the falcons, such as the Kestrel or Sparrow Hawk Falco sparverius, are pointed.Īll accipiters generally have similar colouring, small heads, long tails, and short rounded wings. Like the buteos (e.g., the Red-tailed Hawk Buteo jamaicensis) and harriers (the Northern Harrier Circus cyaneus is the only Canadian harrier), the accipitrine hawks have rounded wings however, these are shorter than in the other two groups. The Sharp-shinned Hawk is found in North, Central, and South America, the Cooper’s Hawk only in North America, and the Northern Goshawk on five continents.Īccipiters can be distinguished from other types of hawks by their flight silhouettes (see sketch). The Canadian species are the Sharp-shinned Hawk Accipiter striatus, the Cooper’s Hawk Accipiter cooperii, and the Northern Goshawk Accipiter gentilis. Accipiters are small to medium-sized hawks of swift flight that occur around the world. He was originally banded in the same state in 1999.Of the 19 species of raptors, or birds of prey, in Canada, three are Accipiters. The oldest recorded Sharp-shinned Hawk was a male, and at least 12 years, 2 months old when he was recaptured and rereleased during banding operations in Minnesota in 2009.Swallowing feathers is not normal for them, as it is for owls. ![]()
