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.

Lesser scaup well as seeds and other parts of aquatic plants like sedges and bulrushes (Cyperaceae), "pondweeds", widgeon-grass ("Ruppia cirrhosa"), wild celery ("Vallisneria americana") or wild rice ("Zizania"). In winter, but less so in summer, other aquatic animals—crustacean, insect and their larvae and small fishes—form an important part of their diet. It has been reported that both the lesser and the greater scaup have shifted their traditional migration routes to take advantage of the presence of the zebra mussel ("Dreissena polymorpha") in Lake Erie, which was accidentally introduced in the 1980s and has multiplied enormously. This may pose a risk to these
