Waterbird Migration Near the Yukon and Alaskan Coast of the Beaufort Sea : II. Moult Migration of Seaducks in Summer
Westward moult migrations of seaducks were studied in the summers of 1972 and 1975 (northern Yukon) and 1977-78 (west of Prudhoe Bay, Alaska). Methods used were visual observations from the coast, aerial surveys, and (in 1975) DEW radar. Many male Oldsquaws (Clangula hyemalis) fly west near the nort...
