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.
Wilson's Bird-of-paradise
Wilson's bird-of-paradise is one of the most extraordinarily colored birds on Earth. Males meticulously clear a patch of forest floor as a display court, removing every leaf and twig. The species was virtually unknown to science until the late 20th century due to its restricted island range.
