Atlantic and Great Lakes Sea Duck Migration Study

More than half of North American sea duck populations have apparently declined over the past 2-3 decades, although reasons for declines are unknown. Population delineation (i.e., the links among breeding, molting, wintering, and staging areas) is critical information needed to design and interpret monitoring surveys, to better understand population ecology and population dynamics, and determine limiting factors and potential strategies to improve conservation status of sea ducks.

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

Holocene underkill, Pleistocene Overkill, Chendytes lawi

PNAS March 18, 2008 vol. 105 no. 11 4077-4078
For many years, it was widely assumed that Chendytes had been lost toward the end of the Pleistocene, even though there were early reports of material from archaeological contexts. Survival well into the Holocene became clear in 1976, when G. V. Morejohn (11) reported C. lawi bones in an archaeological site north of Santa Cruz, California dated to between 5,400 and 3,800 14C years ago. He estimated that the extinction of this bird had occurred between 2,500 and 3,000 years ago.
