The Paradise Shelduck is New Zealands only Shelduck. They have goose like feathers and the males make the characteristic "honk honk sound". The ducks pair for life. While their population is stable, there have been some declines from over-hunting.
We saw them quite frequently on our travels in New Zealand. Unlike many in the bird kingdom, it is the female that is more eye catching than the male. Above is a female with a couple of chicks at Mount Aspiring National Park.
