New Zealand scaup New Zealand scaup The New Zealand scaup ("Aythya novaeseelandiae") commonly known as a black teal, is a diving duck species of the genus "Aythya". It is endemic to New Zealand. In Māori commonly known as papango, also matapouri, titiporangi, raipo. Overall dark brown/black colors. The male has a striking yellow eye and a dark colored (greenish) head. The female is similar to the male, but without the yellow eye and has a white face patch during breeding season. A white wing bar can be seen in both sexes when in flight. The scaup is a diving duck which may submerge
Lesser scaup more often than those of the greater scaup—particularly during flight—but their call is weaker, a guttural "brrtt, brrtt". Lesser scaup are often hard to distinguish from the greater scaup when direct comparison is not possible, but in North America a large scaup flock will often have both species present. Females, juveniles and drakes in eclipse plumage are hard to identify; there is considerable overlap in length between the two species, but greater scaup are usually noticeably more bulky. Lesser scaup females and immatures tend to have less white around the bill, but this too varies considerably between individual birds. The
