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 …

Harpy Eagle

The harpy eagle is among the most powerful raptors in the world, with talons as large as a grizzly bear's claws. It is the national bird of Panama. Deforestation poses the greatest threat to this species, as each breeding pair requires a vast territory of undisturbed forest.
