Paradise Shelduck

Overview

The Paradise Shelduck is a large, boldly patterned waterfowl endemic to New Zealand, known locally as putangitangi. It is unusual among ducks for its dramatic plumage difference between sexes, making males and females easy to tell apart at a glance even from a distance.

Pairs mate for life and are commonly seen grazing on pasture near rivers, lakes, and estuaries throughout both main islands of New Zealand.

Feather Identification

• Female head/neck feathers: pure white, sharply contrasting with the rest of the body
• Female body feathers: rich chestnut-orange with fine vermiculated barring visible up close
• Male body feathers: blackish with a subtle green-blue sheen on the head and dark grey barring on the back
• Flight feathers: dark, glossy, with white wing patches visible in both sexes during flight
• Shaft: sturdy, typical of a large dabbling-type duck
• Sex is the primary identification cue; unlike many ducks, males lack bright color and females are the more vividly plumaged sex

Plumage Notes

Adult females have a striking white head contrasting with chestnut body plumage, while males are almost entirely blackish-grey with a faint green sheen on the head. Juveniles resemble adult males initially, with females developing the white head as they mature.

Adults undergo an eclipse-like flightless molt period after breeding, during which they gather in flocks on open water or pasture while replacing flight feathers.

Habitat & Range

Paradise Shelducks are widespread across New Zealand, occupying pastureland, riverbeds, lake margins, and estuaries. They have adapted well to farmland, often seen grazing in open fields near water.

The species is largely resident, though some flocking and local movement occurs outside the breeding season, particularly during the molt period.

Behavior & Field Notes

Pairs are territorial and mate for life, defending grazing and nesting areas with loud, distinctive calls, the female's cry higher-pitched than the male's. They feed on grasses, seeds, and invertebrates in pasture and shallow water.

Nests are built in tree hollows, dense vegetation, or other sheltered sites near water, lined with down. Their calls carry over long distances and are a familiar sound of New Zealand farmland.
