Genus Species subspecies Region Range
Leucopternis semiplumbeus LA Honduras to nw Ecuador


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

It is a distinctly bicolored hawk, dark gray above with a white throat and underparts. In addition, this species has conspicuous yellow eyes and orange legs and cere

Latin America : Honduras to Northwest Ecuador. Northeastern Honduras (Gracias a Dios) south through the Caribbean slope of Nicaragua, Costa Rica, and Panama to western Colombia and northwestern Ecuador (Esmeraldas).


The Semiplumbeous Hawk is restricted to humid forests in the tropical and subtropical zones the lowlands and foothills from Costa Rica south to the Choco biogeographic region of northwestern South American.


The nest is a platform of sticks placed high in the forest canopy. No further data.

Feeding habits

The limited dietary information available suggests that it feeds on lizards and snakes with a sit and wait strategy, much like other species of Leucopternis.

This species has a very 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 small, 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.
Additionally, there are tantalizing records of birds ascribed to this species from western Amazonia, near Iquitos, Peru, which could well turn out to be new population of Semiplumbeous Hawk, or, perhaps, even an undescribed species.
