Genus

Members of the genus Leucopternis are small to medium-sized buteonine hawks with short and rounded wings and a moderate length tail. In some species the sides of the head are partly bare of feathers and brightly coloured, as are the legs. P1umage pattern is quite simple; immatures are similar to adults. This large genus is placed between Buteo and Buteogallus, and contains ten species, all tropical American.

Physical charateristics

The White-browed Hawk is distinctive in Amazonia with an all black back and head with some white mottling, and white below with an obvious white supercilium.

Habitat

The White-browed Hawk is a denizen of the interior of humid lowland forest in southern Amazonia.

Reproduction

It is very poorly known with very limited information on its breeding or natural history. A nest was about 15 m high in the fork within the subcanopy of a canopy height tree in terra firme forest with a dense understory. The nest was “an untidy, near-hexagonal structure constructed of sticks and some smaller twigs, and lined with a handful of dead leaves on its outer walls.”

Feeding habits

A snake and a lizard are the only confirmed prey in its diet. IN Bolivia, one was captured when it descended on a woodcreeper from a net, and its stomach contained the remains of several small birds.

Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
White-browed Hawk status Least Concern

Migration

Probably non-migratory.
