[Ornithology • 2013] Discovery of the critically endangered Flores Hawk-Eagle Nisaetus floris on Alor island, Indonesia



The Flores Hawk Eagle Nisaetus floris was first treated as a separate species by Gjershaug et al. (2004) because it is morphologically distinct from Changeable Hawk Eagle N.cirrhatus; it was previously considered to be a subspecies of the latter. It is now an Indonesian endemic only known to occur on Flores, Sumbawa and Lombok as well as on two satellite islands, Satonda near Sumbawa and Rinca near Flores. Komodo was mentioned by Coates & Bishop (1997) as part of the range but no further details were provided. However further confirmation came in November 2011 when a bird was photographed on a tiny island just 800 m from Komodo, perched in mangroves, presumably examining a colony of fruit bats roosting there.
