Anas erythrorhyncha (Red-billed Teal)

Synonyms: Anas erythrorhynchos

Wikipedia Abstract

The red-billed teal (Anas erythrorhyncha) is a dabbling duck which is an abundant resident breeder in southern and eastern Africa typically south of 10° S. This duck is not migratory, but will fly great distances to find suitable waters. It is highly gregarious outside the breeding season and forms large flocks. This is a quiet species, but the displaying male has a whzzt call, whereas the female has a soft Mallard-like quack. This is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
