Hieraaetus

The genus Hieraaetus, sometimes known as small eagles or hawk-eagles, denotes a group of smallish eagles usually placed in the accipitrid subfamilies Buteoninae or Aquilinae.

They are generally medium-sized birds of prey inhabiting Europe, Asia, Africa, New Guinea and Australia. However, a recently extinct species, the New Zealand Haast's eagle, was the largest eagle ever known, weighing up to 17 kg (37 lb), with a 3 m (9.8 ft) wingspan.
