Bonelli's Hawk Eagle is a large bird of prey with two subspecies: 1. Hieraaetus fasciatus fasciatus distributed in northwest Africa, Iberian Peninsula, Mediterranean, Asia, Arabian Peninsula, Afghanistan, Pakistan, India, Indochina and southern China. 2. Hieraaetus fasciatus renschi distributed in western Somba, East Timor, Weta, Luang Prabang and Lesser Sunda Islands.

The white-bellied falcon eagle lives in mountainous areas, hills and places with abundant water sources. In the mountainous areas of Fujian, China, young birds that have just left the nest can be seen in early August. In Feixi, Anhui, female young birds of the year were collected in November. It uses branches and leaves to build nests on tall trees or cliffs. The breeding season is from March to May. It nests on cliffs or trees on the banks of river valleys. The structure of the nest is relatively large, mainly composed of dead branches, with a few twigs inside. Each nest lays 1-3 eggs, usually 2. The eggs are oval in shape, white in color, generally without spots, and some have a few yellow-brown spots at the blunt end. The parents take turns to incubate the eggs, and they are very protective of the nest. The incubation period is 42-43 days. The chicks are late-maturing, and when they are just hatched, they are covered with white down feathers. They are fed by the parents together for about 60-80 days before their feathers are full and they leave the nest.
