About These Birds
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.
Freckled Duck
An unusual Australian duck with dark brown plumage densely speckled with small pale spots. Considered a living fossil with no close relatives—placed in its own subfamily. Males have a red base to the bill in breeding season. Found in inland Australia; highly nomadic following rainfall.
