Anas smithii (Cape Shoveler)

Synonyms: Anas smithi; Spatula smithii (homotypic)

Wikipedia Abstract

The Cape shoveler or Cape shoveller (Anas smithii) is a species of dabbling duck of the genus Anas. It is resident in South Africa, and uncommon further north in Namibia, Botswana, Zimbabwe, southern Angola, Lesotho, Mozambique, and Zambia. This 51–53 cm long duck is non-migratory, but undertakes some local seasonal movements. It is gregarious when not breeding, and may then form large flocks. Cape shoveler can only be confused with a vagrant female northern shoveler, but is much darker and stockier than that species. The binomial name of this bird commemorates the zoologist Andrew Smith.
