Ruddy Duck (Oxyura jamaicensis)
Ruddy Duck
Overview:

Small, plump diving duck 14” to 16” long with an average wingspan of 23”. The plumage of drakes varies with the seasons. In winter it is gray-brown with white cheek patches, while in breeding season the body feathers are a warm brown, feathers on the top of the head are black, and the usually black bill turns blue. Hens are gray-brown and have a dark stripe across their white cheek patches. Ruddy ducks also are distinguished by their forward-tilting tail.

Habitat:

Brackish waters of tidal rivers and inlets.

Range:

Ruddy ducks of the Atlantic Flyway typically breed across Canada and migrate to the Chesapeake in autumn.

Diet:

Mainly aquatic plants, insects, and worms.

Call:

Silent except for courting males, which make a soft clicking sound by striking the bill against the breast. Listen to a sample (Requires RealPlayer)

Cool Facts:

Like only a few other species of waterfowl, ruddy ducks have the ability to elude potential predators by slowly submerging like feathered submarines—out of sight, out of danger.
