Fun Facts

In the wild, these ducks may use holes and burrows made by other animals to build their nest.

Within days of hatching, the young are led from the nest to, what field scientists call, "nursery water" by both parents or sometimes by other adults to the nursery water. This distance can be a mile or more! In the nursery there are several young from other parents together under the care of one or more adults. The nursery group (or crèche) varies in size and age range (a normal size crèche is 20 to 40 individuals, but some groups of 100 have been recorded). Scientists believe the nursery supervisors are failed breeders or non-breeders.

Shelducks are not diving birds, but they are able to dive if needed. The young ducklings dive freely but the adults only do so when wounded or frightened.

These ducks communicate using goose like honks, grunts, and whistles.

Ecology and Conservation

The Australian shelduck is not a popular game bird so it has not been significantly over-hunted. What little hunting there is stems from their habit of grazing in agricultural fields, causing damage to crops.

Scientists believe their populations may have grown in recent years due to the increase of irrigation in agriculture and the construction of new water impoundments, which both provide more food and more habitat for this specific species.
