Circus spilonotus (Eastern Marsh Harrier)

Synonyms: Circus aeruginosus spilonotus

Wikipedia Abstract

The eastern marsh harrier (Circus spilonotus) is a bird of prey belonging to the marsh harrier group of harriers. It was previously considered to be conspecific with the western marsh harrier (Circus aeruginosus) but is now usually classified as a separate species. It has two subspecies: C. s. spilonotus in eastern Asia and C. s. spilothorax (Papuan harrier, perhaps a separate species) in New Guinea.
