Originating from Central Africa, it has spread throughout the African continent and Madagascar.
It does not present sexual dimorphism, males and females are apparently the same and cannot be easily distinguished except by their behavior. It has been domesticated and naturalized outside its natural geographic distribution.
Although their diet is primarily herbivorous they also feed, to a lesser extent, on invertebrates.
They are monogamous, but the pair do not stay together outside the breeding season. They nest on the ground and the clutch consists of 6-12 eggs and incubation is 25-30 days.
They are social birds that form flocks of up to a thousand individuals. They move on the ground and are very fast, although at night or when they feel threatened, they climb trees.
