Clanga hastata appears to be a widespread species that has always been recorded at very low densities in the lowlands of the Indian subcontinent, occurring in
Pakistan,
Nepal,
India, and
Myanmar (Robson 2000, Parry
et al. 2002, Rasmussen and Anderton 2005, Tordoff
et al. in press), and may be extinct in
Bangladesh (Robson 2008). Several sightings in
Cambodia (e.g. an individual in display flight in February 2007 [per P. D. Round
in litt. 2007] were regarded as almost certainly referring to this species, and its occurrence there was confirmed following the discovery of a captive bird in 2009 in a village in Kampong Thom Province (Handschuh
et al. 2011). This confirmed record and later confirmed photographic records indicate a wide, possibly patchy distribution within low-lying open deciduous dipterocarp forest mosaics across northern Cambodia (P. Davidson
in litt. 2003, Handschuh
et al. 2011) However, no focussed survey has been conducted to date. This raises the possibility that the species may have occurred historically across other parts of Southeast Asia, although today it has almost certainly been extirpated from much of this area due to habitat loss, hence declines are inferred in the past. Ascertaining its true status and distribution is hampered by identification problems, and an unknown proportion of records of this species may actually relate to Greater Spotted Eagle
C. clanga. Photographic evidence is therefore usually required to accept sightings
