Comparative morphology of Haast's Eagle with its closest living relative the Little Eagle.

The Little Eagle (Aquila morphnoides) is a very small eagle native to Australasia, measuring 45"?55 cm (17"?21.5 inches) in length and weighing 815 g (1.8 lb) "? roughly the size of a Peregrine Falcon. It tends to inhabit open woodland, grassland and arid regions, shunning dense forest. It is a near relative of both the Palearctic Booted Eagle and, remarkably, the massive but now extinct Haast's Eagle of New Zealand.
