Popis:	Summary. 1 The habits of the Black Crow in Eastern Cape Province are described. Resident pairs are strongly territorial, but roving flocks feed over wide areas. 2 Main breeding season is from August to November. 3 Incubation period about 18 days, both parents sharing incubation. 4 Nestling period about 38 days, both parents feeding young. 5 Diet is very varied, e.g. vegetable matter, including seeds, fruits and bulbs; insect matter, especially dung-beetles; vertebrates, such as amphibia and small chickens. Indigestible matter is regurgitated in pellets.
