Feeding

They are a diving duck and may stay down for twenty to thirty seconds and go down three metres to look for aquatic plants, small fish, water snails, mussels and insects. It is sometimes seen with the Australian Coot (Fulica atra); it is thought that the Scaup takes advantage of the food stirred up by the Coots as they fossick for shrimps.

Distribution

Found throughout both North and South islands of New Zealand in deep freshwater lakes and ponds. Unlike other members of this genus this scaup is not migratory, although it does move to open water from high country lakes if they become frozen in winter.

Life cycle

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 duckling take to diving for food on their first outing.
