THE BREEDING RANGE OF THE BARROW'S GOLDENEYE IN EASTERN NORTH AMERICA

摘要

tHE BREEDING RANGE OF Barrow's Godeneye (Bucephala islandica) is largely restricted to north- western North America, and little is known of the small population that winters in eastern Canada. Based on weak evidence, this eastern population was thought to nest mainly in northern Labrador. Our May 1990 to 1998 surveys identified a breeding area in the forest regions of the Quebec Laurentian Highlands. We observed Barrow's Goldeneyes on 137 lakes and 5 rivers. Of which 95.2/100 were along the north shore of the St. Lawrence Estuary and gulf. The species was found mainly on small lakes (≤10 ha) at greater than 500 m elevation.
