Song & Call Comparison

Slaty-backed Goshawk

白头海雕

鸣唱

High-pitched, chattering whistle: a rapid 'kleek-kik-ik-ik-ik'. Surprisingly weak and thin for such a large raptor. Also gives a lower 'kwit-kwit' call near the nest.

About These Birds

Slaty-backed Goshawk

The Slaty-backed Goshawk (<em>Accipiter luteoschistaceus</em>) is a forest raptor in the family Accipitridae, the hawks, eagles, and kites. It is endemic to the Bismarck Archipelago of Papua New Guinea, primarily recorded from New Britain and New Ireland, where it inhabits tropical forest environments. This species is assessed as Vulnerable by the IUCN, reflecting its restricted range and susceptibility to habitat loss from logging and forest clearance across the Bismarck islands. Detailed plumage and behavioral descriptions of this species are limited …

白头海雕

The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
