Distribution and habitat
This species occurs in two large separate regions of the African continent. One form ranges from the Cape at the southern tip of Africa up to southern Angola and across to the east coast of Mozambique. The other population occurs in a large area from South Sudan, Ethiopia, Tanzania and Kenya in central east Africa. The more northern population is on average slightly smaller than the southern. It inhabits open grassland, moorland, agricultural areas with some trees or woodland in the vicinity for nesting. It seems to thrive especially in agricultural areas.Behaviour
Diet
As far as feeding is concerned, it eats grain and other seeds, invertebrates which it digs for with powerful downward stabs of its long bill. It opens corncob kernels before they are fully ripe, bulbs and fleshy roots of certain plants, frogs and small reptiles, fruits and berries. It takes the eggs and chicks of ground nesting birds and has been known to kill birds of up to a pound in weight (especially domestic poultry). It turns over the droppings of mammals for insects.Nesting
Nesting is always in trees, usually near the top. It has been known to nest in shrubs but much less frequently. There are usually 3-4 eggs incubated over 18–19 days and fledged by around 38 days. Usually only 3 nestlings survive.Voice
The voice is described as a ''"krrah.....krrah.....krrah"'' or a quicker ''"kah-kah-kah"''. It also makes very loud, liquid bubbling sounds that carry quite a distance and also gives throaty chuckles. There is evidence that vocal mimicry is practised too.References
