Flores Hawk-eagle

Nisaetus floris


The Flores Hawk-eagle is believed to be found on six islands in Indonesia, and although they are essentially non-migratory, individuals are known to move between these islands.

As this is a rare species, very little is known about their breeding behaviour and their habitat and ecology. This species is part of the Acciptridae family, which includes ospreys, hawks, eagles and kites, which diverged from all other birds 49.6 million years ago. Habitat degradation is the most severe threat to this species as forest tracts are turning into cultivated landscapes. Also this species is persecuted, due to its habit of preying on chickens. As a rare species, it is valuable for the live bird trade and also the taxidermy trade. This species range is in a protected area, but this is too small to ensure its long term survival. Work is underway to inform local people of the importance of this species. Burung Indonesia is currently running a forest conservation project in western Flores, where this species is found.

The species is found in Indonesia.

Habitat and Ecology

This species lives in lowland submontane forest up to 1,600 metres above sea level. This species is always close to intact or semi-intact forest. The species can disperse across the narrow straits between islands, so mixing between island sub-populations is inferred. Breeding takes place during the dry season.

This wordcloud illustrates the threats facing this species. The size of each word indicates the extent of a species range that is affected by that threat (larger size means a greater area is affected). The colour of the word indicates how much that threat impacts the species (darker shades of red mean the threat is more severe).
