Blue duck standing on one leg with wing outstretched
The blue duck (or whio; Hymenolanimus malacorhynchos) is a unique threatened species of waterfowl endemic to New Zealand. It is the only member of its genus and has no close relative anywhere in the world.
The blue duck is believed to have appeared at a very early stage in evolutionary history and the species’ isolation in New Zealand has resulted in it acquiring a number of unique anatomical and behavioural features.
Did you know that whio/blue duck are one of only three species of waterfowl in the world that live on fast flowing rivers year round? Learn more about this threatened species.
Habitat loss, introduction of predators and human disturbance have all played a role in the decline of the whio/blue duck populations.
