Grey Duck (Anas superciliosa superciliosa) x Mallard hybrids, Wilderness Lodge, Lake Moeraki, West Coast, South Island, New Zealand
Parera in Maori. Also known as Pacific Black Duck
Grey Ducks have hybridised readily with feral Mallard (Anas platyrhynchos), diluting the purity of the species, so that pure-bred individuals are now extremely rare. The faces of these specimens are very Grey Duck-like but the blue not green speculum in the wing with a white edge is typical of Mallard. So these specimens are Grey Duck x Mallard hybrids. Thanks to Prof Paul Scofield.
