New Zealand scaup They nest from October to March. They lay five to eight cream/white eggs in a nest close to water, often under banks or thick cover. The nest is usually lined with grass and down. The eggs are incubated for four weeks by the female. The newly hatched ducklings begin diving for food on their first outing. 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.
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
