They are usually seen around fruiting trees as they forage for food.
Their diet consists of various fruits, such as wild fig (Ficus), Saffrons (Cassine spp.), Jacket plum (Pappea capensis), Buffalo thorn (Ziziphus mucronata), Water berry (Syzygium cordatum), Jackalberry (Diospyros mespiliformis), exotic Loquats and Mulberries. On occasion they may take carrion.
