Atlantic and Great Lakes Sea Duck Migration Study
In 2009, the Sea Duck Joint Venture (SDJV) launched an ambitious, large-scale satellite telemetry study of sea ducks in the Atlantic Flyway. Target species include black scoter, surf scoter, white-winger scoter, and long-tailed duck, all of which are species of conservation concern. The overall goal of the study is to improve understanding of the links among breeding, wintering, staging, and molting areas (i.e., population delineation) for these species, which is essential to understanding sea duck population declines and limiting factors.
