About These Birds
Cackling Goose
A small version of the Canada Goose with a stubby bill, rounded head, and shorter neck. Long treated as a subspecies; now recognized as a separate species with four subspecies. Migrates from Arctic breeding grounds to wintering areas in the central United States. Gregarious; mixes with Canada Geese in winter.
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.
