Taxonomy
New studies place this species in the genus Nisaetus instead of Spizaetus.
Subspecies[1]
Five subspecies are recognised which are sometimes split in two species:
Crested Hawk-Eagle (Nisaetus cirrhatus):
Changeable Hawk-Eagle (Nisaetus limnaeetus)
- limnaeetus from north-east India to the Philippines, Borneo, and Java
- andamanensis in the Andaman Islands
- vanheurni on Simalur
Flores Hawk-Eagle was recently split from this species[1], [2].
Clements [1] now splits this species. However, the other worldlists don't follow yet and the Opus awaits further clarification.
Habitat
Forest and open woodland from sea-level up to 3,300m, hunting over forest edge and clearings.
Behaviour
