Typical Environment
Occurs throughout much of New Guinea, nearby islands such as the Bismarck Archipelago, and east Indonesian islands within Wallacea. Prefers extensive primary and tall secondary forests but also uses forest edges, river corridors, and mountainous ridges. It is chiefly a canopy and above-canopy hunter, often soaring to survey large tracts of habitat. Rare vagrants reach northern Australia.

Gurney's eagle is a powerful forest raptor of New Guinea and Wallacea, often seen soaring above ridges and forest edges. Adults are mostly dark, while juveniles are noticeably paler below, which can cause confusion with other large raptors. It hunts a wide range of prey from birds to reptiles and small mammals. Ongoing forest loss is the primary threat across parts of its range.

Social Behavior
Typically encountered singly or in pairs, with pairs holding large territories over tracts of forest. Courtship includes mutual soaring and display flights over ridgelines. Nests are large stick platforms placed high in emergent trees; clutch size is small and breeding cycles are prolonged, as in many large eagles.
Migratory Pattern
Resident
Song Description
Generally quiet, but gives high, thin whistles and yelping calls, especially near the nest or during display. Vocalizations carry over valleys when birds are circling high. Calling is most frequent during the breeding season.
