About These Birds
Laughing Kookaburra
The laughing kookaburra is the largest kingfisher in the world, famous for its raucous laughing call that has become an iconic sound of the Australian bush. Despite being a kingfisher, it rarely eats fish, preferring terrestrial prey. Family groups perform chorus calls at dawn and dusk to mark their territory.
Mallard
The mallard is the ancestor of most domestic duck breeds and the most abundant and widespread dabbling duck in the world. Males perform elaborate courtship displays including head-bobbing and whistle-grunt calls. Mallards are highly adaptable, thriving in both wilderness and urban environments.
