About These Birds

Mottled Duck

A medium-sized buff-brown dabbling duck closely related to the Mallard, with a plain brown body, yellow bill, and blue speculum. Non-migratory; restricted to coastal marshes of Florida and the Gulf Coast. Threatened by hybridization with introduced Mallards in Florida.

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.
