Paradise shelduck, male - photographer: Max McRaeA large goose-like duck with orange-chestnut undertail and tertials. The male has a black head with a greenish gloss and a dark grey finely barred black body. Some males have white feathering around their eyes. The female has a white head, and a bright orange-chestnut body, obscured by darker fine barring in eclipse plumage. In flight both have prominent white patches on the upper wings.

They are very vocal; the male call is a ‘zonk-zonk…’, and the female call a shrill ‘zeek-zeek’. They are usually seen in pairs or flocks on farmland, lakes, ponds and high-country riverbeds. All birds gather at traditional moult sites in December–February, and disperse again in March–April.

'DAPHNE' - photographer: Simon FordhamBreeding is between August and December and birds pair for life. The nest of grasses, lined with down feathers is usually built in hollow logs, burrows, rock crevices, under exposed tree roots, or in a tree hole up to 25 metres above the ground. The clutch of 5–15 white eggs is incubated by the female for 30-35 days. Once the eggs have hatched, the chicks are led to open water, which can be over a kilometre away; they fledge at about eight weeks old.

Paradise Shelduck graze on grass and clover, grass seeds and weed seeds, and stubble or standing crops of peas or grain, causing damage to young pasture, hay and grain crops. They also eat aquatic vegetation.

There is at least one pair of paradise shelducks on Tiri, usually in the vicinity of the Ranger's house and bunkhouse. Another pair often frequents the north end of the Island near the Silvester Wetlands. Unfortunately, although they often hatch 2-3 broods per year, they hardly ever manage to rear the chicks beyond the first two or three weeks. The large numbers of pūkeko, which are often aggressive towards the ducklings, are probably to blame for this.
