Fun Facts
Magpie geese often breed in trios rather than pairs. Two females lay their eggs on a floating platform of reeds made by a single male. After the eggs hatch, the three parents feed the chicks by bending tall grasses over with their feet so the goslings can eat the seeds.
Unlike most waterfowl, these birds do not molt their flight feathers all at once, as a result, they are always able to fly.
Some scientists believe the magpie goose more closely related to screamers than other waterfowl. In fact, they are not closely related to true ducks.
These birds are the only known waterfowl to feed their young.
Ecology and Conservation
The magpie goose plays an integral part in the lives of Aboriginal people across northern Australia. The geese and their eggs are hunted for food.
These birds once lived in swamps throughout Australia; however, large populations have been poisoned because they are considered agricultural pests. In addition, much of their breeding habitat has been drained to create additional farmland.
