This bird is an Old World vulture (only distantly related to the New World vultures, which are in a separate family, the Cathartidae).
It breeds in forest and savannah across sub-Saharan Africa, usually near water, its range coinciding with that of the oil palm. It is quite approachable, like many African vultures, and can be seen near habitation, even on large hotel lawns in the tourist areas of countries such as the Gambia
