Their range includes Angola, Benin, Botswana, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Eswatini, Ethiopia, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Malawi, Mali, Mauritania, Mozambique, Namibia, Niger, Nigeria, Rwanda, São Tomé and Príncipe, Senegal, Sierra Leone, Somalia, South Africa, South Sudan, Tanzania, Togo, Uganda, Zambia and Zimbabwe.




Habits


As with others in their genus, they frequent tree canopies where their parrot-like climbing ability enable them to reach fruit, but rarely also forage on the ground. Their call is a series of flowing whistles, rendered as ‘thweeeloo, thweeeoo’. They inhabit riparian forest, woodland and savanna, where they associate with fruiting trees, especially wild fig (Ficus) species, including Ficus sycomorus and Ficus sur, and in cities the ornamental Chinese banyan. They also take fruit of Saffrons (Cassine spp.), Jacket plum (Pappea capensis), Cordia africana , Buffalo thorn (Ziziphus mucronata), Water berry (Syzygium cordatum) and Jackalberry (Diospyros mespiliformis). They may also feed on exotic Loquats and Mulberries, or on carrion by occasion.




Nesting


They nest in a tree fork that offers an adequate vantage point of their surrounds. The nest is a weak platform of sticks, collected by the male and arranged by the female. Nesting may take place in any month of the year, though mostly in summer. 1–2 eggs are laid that hatch in 13–14 days. Chicks leave the nest at about 12 days.
