LC
Pygmy Eagle Hieraaetus weiskei



Justification

Justification of Red List Category
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 has not been quantified, 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.

Population justification
The global population size has not been quantified, but it is believed to be large, even though the species is described as well distributed but scarce (Coates 1985).

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction (Ferguson-Lees and Christie 2001).

Distribution and population

This species has a large range in New Guinea (Papua New Guinea and Indonesia).

Ecology

The species occurs in open forest, woodland, scrub and savanna, and over rainforest, from sea-level to 1950 m (Thiollay 1994).
