The Papuan harrier is a bird of prey endemic to New Guinea and was long treated as a subspecies of the eastern marsh harrier before being recognized as a distinct species. Like other harriers, it hunts by quartering low over open country, using keen eyesight to detect prey. It shows strong sexual dimorphism in plumage, with females markedly browner than males. Nests are built on the ground in dense grasses or marsh vegetation.
Temperament
solitary and territorial
Flight Pattern
low quartering flight with buoyant glides and intermittent, elastic wingbeats
Social Behavior
Generally solitary or in pairs during the breeding season, defending nesting areas within suitable marsh or grassland. Nests are placed on the ground in dense vegetation and both sexes participate in territory defense, with the female primarily incubating. Outside the breeding season, loose roosting aggregations may form in suitable open-country roost sites.
Migratory Pattern
Resident
Song Description
Usually quiet away from the nest, giving sharp, high-pitched whistles and chattering calls during courtship and territorial displays. Alarm calls near the nest are more insistent and repeated.
