Long-tailed Hawk
Urotriorchis macrourus
An aptly named hawk of lowland African forest, identifiable by its distinctive profile as it flies through open areas. This species’ long, black-and-white striped tail contrasts with its white vent and rump. Also shows a slate-gray back and head, solid rufous underparts, and a white throat. The rare dark morph appears blacker above, with slate-colored underparts. Gives a loud scream, one second long, that falls in pitch toward the end, often followed by a second, louder scream. Overlaps with the smaller Red-chested Goshawk, but note the disproportionately long tail.
识别特征
The long-tailed hawk is a distinctively shaped raptor with a very noticeable long, barred tail and is dark grey on its upperparts and chestnut on its underparts with a contrasting white throat and undertail coverts. In flight the white flight feathers on the underwing are heavily barred with dark grey. There is a rare morph which has a grey breast, with a paler grey throat but still has the white undertail coverts. The bill is black, the eyes, cere, legs and feet are yellow. Juveniles are browner, with a white-breasted "plain" morph and a "marked" morph which has the breast streaked with brown. It has a wingspan of 81–90 centimetres (32–35 in) and a total length of 56–65 centimetres (22–26 in), including the tail of 30–37 centimetres (12–15 in). Females are about 15% larger than males. Since the tail comprises about 56% of this raptor's total length, this species ties with the cinereous harrier as the raptor with the longest tail relative to its body size.<p>It is a rather vocal bird which is often first detected by the long drawn out screech given by birds perched in the canopy.
