Distribution and habitat preferences

The Blue-billed Duck is almost entirely aquatic. While they have been observed on land, they have difficulty walking, exhibiting a penguin-like gait. During non-breeding season, many ducks gather in flocks totalling several hundred, especially juveniles and younger adults, in open lakes or dams in autumn and winter, far from the shore. For the rest of the year, during breeding season, the Blue-billed duck prefers deep, freshwater swamps, with dense vegetation. They have also occasionally been found in large rivers and saline water bodies such as billabongs. (Wikipedia)
