Taxonomy

Taxonomic note
Clanga hastata (del Hoyo and Collar 2014) was previously placed in the genus Aquila.

Aquila pomarina (Sibley and Monroe 1990, 1993) was previously split into A. pomarina and A. hastata following Parry et al. (2002).

Population justification: This species apparently occurs at very low density and nowhere is it common, so, despite its large range, the global population is believed to fall below 10,000 individuals. It is placed in the band 2,500-9,999 mature individuals, equating to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals. Improved knowledge of its status in Cambodia, where it was confirmed to occur following the discovery of a captive individual in 2009, and elsewhere in Southeast Asia, may necessitate an upwards revision of the population estimate in the future.

Trend justification: The species is thought to be in decline at a slow to moderate rate, owing to on-going habitat conversion within its large range. Further research, however, is required to provide a more accurate estimate of its rate of decline, and identify the causes.
