Range Description

Nisaetus floris is found in Indonesia, on the islands of Flores, Sumbawa and Lombok (on the borders of Rinjani National Park) as well as on two satellite islands, Satonda near Sumbawa and Rinca near Flores (Gjershaug et al. 2004). The species has also occurred on Komodo, with an individual photographed on a mangrove islet less than 800 m offshore in 2011 (Coates and Bishop 1997, Collaerts et al. 2013). It has recently been discovered on Alor and is apparently present throughout the island (Collaerts et al. 2013). A record from Paloe (Verheijen 1961) has not been confirmed. Its population size has been estimated at fewer than 100 pairs, based on the extent of suitable habitat and a territory size estimate of c.40 km2 (Gjershaug et al. 2004), although it is estimated that at least 20 additional pairs inhabit Alor (Collaerts et al. 2013). The lack of records obtained during fieldwork within its range suggest it occurs at low densities, supporting this population estimate. Population trends are not known, but it is assumed to be declining owing to on-going forest loss in the Lesser Sundas.
