LC
Black-and-white Hawk-eagle Spizaetus melanoleucus



Justification

Justification of Red List Category
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.

Population justification
Partners in Flight estimated the population to number <50,000 individuals (A. Panjabi in litt. 2008).

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction and human disturbance. Although it is able to tolerate some habitat degradation and human disturbance (Ferguson-Lees and Christie 2001).
