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.
Northern Shoveler
A medium-sized duck with a dramatically large spatula-shaped bill perfectly adapted for filter-feeding. Males have an iridescent green head, white breast, chestnut flanks, and sky-blue wing patches. Highly migratory; one of the Northern Hemisphere's most widespread ducks.
