The yellow-billed duck (Anas undulata) is a 51–58 cm long dabbling duck which is an abundant resident breeder in southern and eastern Africa. This duck is not migratory, but wanders in the dry season to find suitable waters. It is highly gregarious outside the breeding season and forms large flocks.
It is a bird of freshwater habitats in fairly open country and feeds by dabbling for plant food mainly in the evening or at night. It nests on the ground in dense vegetation near water. Rarely, it is found in suburban areas, in close proximity to golf courses, parks and lakes or dams.
The male has a teal-like whistle, whereas the female has a mallard-like quack.
There are two subspecies of the yellow-billed duck: A. undulata rueppelli (northern yellow-billed duck) and A. undulata undulata (southern yellow-billed duck). The yellow-billed duck is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.Source : wikipedia
