Hab. Africa generally, south to the Cape Colony ; Turkey and Palestine ; of doubtful occurrence in south-western Europe.
In habits it differs but little from its allies and is a some¬what heavy bird, preferring carrion, frogs, fish, and even worms, to hunting after larger birds and mammals, but it will capture hares and rabbits, and often robs the sportsman of wounded game, its call-note is (fide von Erlanger) ichtioh, ichtioh. Its nest is a large heavy structure of boughs, twigs, and dry grass, and is placed on a tree. The eggs, which are deposited in April or May, in Abyssinia in June or August, and on the Blue Nile in January, are white, more or less richly spotted and blotched with pale purplish red and deep rufous and measure about 2.81 by 2.22.
There are two forms of this eagle, one tawny, and the other (Aq. albicans) pale clay ochreous, but intermediate specimens occur.
