Australian Shelduck

ZOO LOCATION: Australia Walkabout

Wild Diet: Short grasses, algae, insects and mollusks

Habitat: Freshwater areas of western and southeastern Australia

IUCN Status: Least Concern

Also known as the "mountain duck," this species is the largest Australian duck. Shelducks sometimes congregate in flocks of more than a thousand birds. To communicate, males honk loudly and females answer with a buzzing call. Populations have grown in recent years due to the increase of agricultural irrigation, which provides the ducks with more wetland habitats.
