The long-crested eagle (Lophaetus occipitalis) is an African bird of prey. Like all eagles, it is in the family Accipitridae. It is currently placed in a monotypic genus Lophaetus.
The long-crested eagle is a distinctive eagle when perched due to the long, shaggy crest and all dark plumage. The adults are blackish-brown with long, thin feathers growing from the rear of the crown which are held erect to forma crest. The secondary feathers are black barred with light grey and with broad black tips, the primary feathers and median underwing coverts are white, forming a noticeable white patch on the upper and lower surfaces of the wing which is visible in flight. The tail is black, barred with pale grey. The eyes of adults are bright yellow but can be darker in females, and the cere and feet are yellow, paling to white in males. The juveniles are similar to the adults, but the plumage is lighter in coloor and the crest is not developed and their eyes are grey. The body length is 53–58 cm (21–23 in) and the weight of the female is 1,300–1,500 g (46–53 oz), while the smaller male is 912–1,300 g (32.2–45.9 oz).
The long-crested eagle occurs in sub-Saharan Africa from Senegal and Gambia eastwards to Ethiopia and south to the Eastern Cape, in South Africa, northern Namibia and northern Botswana. It is generally regarded as sedentary. but in arid areas may be nomadic depending on the rains
The long-crested eagle is a bird of forest edges and moist woodland, particularly if that habitat is near to grassland, marsh, a river or a stream; it can also be found in drier woodland, mixed farmland, grazing land, the edges of sugar-cane plantations and orchards. Long-crested eagles will also use exotic plantations such as those of pine or eucalyptus. They range in altitude from sea level to 3,000 m (9,800 ft), but it is unusual to find them above 2,000 m (6,600 ft).
