The fast flowing clear river at Tirangi.
Habitat for this species.
Notice the bizarre fleshy flaps of skin
hanging from the tip of the bill.
The Blue Duck is a fast declining New Zealand endemic, confined to clear, unpolluted fast flowing rivers & streams. It is threatened by hydro-electricity schemes which dam its habitat; pollution of its crystal clear waters; predation by introduced predators & competition for its food by introduced trout & associated pressure from fishing.
It is found on both North & South Islands, but is much more restricted in distribution on North Island. An initiative was started in 2011 to boost the numbers of Blue Duck & to try & control pest species which prey on this vulnerable species.
