Blue Duck


Blue Duck
IUCN Listing - Endangered - decreasing population
Once they expanded in New Zealand, however, now they are confined to only some mountains in New Zealand with streams that provide a plethora variety of invertebrates for the surviving Blue Duck populations.

Usually the duck stays on the breeding grounds unless there is no longer a sufficient amount of food left, remaining near to rivers
