Female Shelduck. New Zealand.

The paradise shelduck is New Zealand’s only shelduck, a worldwide group of large, often semi-terrestrial waterfowl that have goose-like features.

Unusually for ducks, the female paradise shelduck is more eye-catching than the male; females have a pure white head and chestnut-coloured body, while males have a dark grey body and black head.

Paradise shelducks are commonly observed flying in pairs or grazing on pasture. They are very vocal birds, with males giving a characteristic ‘zonk zonk’, while females make a more shrill ‘zeek zeek’ while flying or as a warning to intruders.
