Techniques for Determining the Availability of Food Items to Seaducks Wintering on the Chesapeake Bay, Maryland

Introduction: Historically, the Chesapeake Bay has been a major wintering area for seaducks. Based on aerial surveys, three species of seaducks, surf scoters (Melanitta perspicillata), black scoters (Melanitta nigra), and long-tailed ducks (Clangula hyemalis), have shown major declines in recent years. One possible explanation for this decline is a reduction of available food items.Data indicates that surf and black scoters likely feed at depths ranging from 10 to 30 feet in the mesohaline region of the Chesapeake Bay.

Sea Duck Ecology - Investigating the wintering ecology of surf scoters and long-tailed ducks

North American populations of breeding surf scoters and long-tailed ducks appear to be decreasing. Along the Atlantic coast, wintering populations of surf scoters are suspected to be decreasing, while the status of wintering populations of long-tailed ducks remains unknown. These trends have led conservation organizations to assign a "high" relative conservation priority to both species.

Atlantic Seaduck Project

The Atlantic Seaduck Project is being conducted to learn more about the breeding and molting areas of seaducks in northern Canada and more about the feeding ecology of seaducks on wintering areas, especially Chesapeake Bay. Satellite telemetry is being used to track surf scoters wintering in Chesapeake Bay, Maryland, and black scoters on migrational staging areas in New Brunswick, Canada, to breeding and molting areas in northern Canada

Handbook of waterfowl Behavior: Tribe Mergini (seaducks)

As constituted here, the tribe Mergini includes all the species which Delacour and Mayr (1945) originally placed in the group.
Delacour later (1959) removed the four species of eiders and placed them in a separate tribe, Somateriini, between the dabbling ducks and
pochards. This was done apparently as a result of Humphrey's anatomical studies (1955, 1958), which suggested that the eiders might
