NT Crested Eagle  Morphnus guianensis

2009 IUCN Red List Category (as evaluated by BirdLife International - the official Red List Authority for birds for IUCN): Near Threatened

Justification This species is rare throughout its vast range, and is thought to be declining moderately rapidly owing to habitat loss and hunting. For this reason it is classified as Near Threatened.

Ecology: It occurs in lowland tropical and subtropical forest, including gallery forest in the south of its range, typically below 600 m but locally up to 1,200 m 1,4.

Threats Its large size and low population densities make it particularly vulnerable to hunting1,2. Deforestation is a severe problem, with many old records from now deforested parts of the Chocó region in north-west Colombia1,2. Similarly extensive deforestation in parts of its Central American range suggest that local contractions of range or serious declines in population have already occurred1,2. It presumably also suffers from competition with humans for prey3.

Conservation measures underway CITES Appendix II.

Conservation measures proposed Survey and attempt to estimate population density and global population. Organise educational campaigns to reduce hunting pressure. Study its ability to persist in fragmented and degraded habitat.
