Barrow’s Goldeneye (Bucephala islandica) is a relatively rare species in the Canadian Atlantic Provinces. Small numbers of birds during moulting and staging periods consistently occur in all four provinces. The Eastern population of Barrow's Goldeneye in North America was assessed in 2000 by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as a species of special concern and was listed as such in Schedule 1 of the Species at Risk Act (SARA) in 2003. The range limits of the eastern population of Barrow’s Goldeneye are still unknown. Small numbers of this population winter in eastern North America, approximately 400 in the Atlantic Provinces and Maine. Based on this information, the wintering population of Barrow's Goldeneye in eastern Northern America is estimated at about 4500 individuals or 1400 pairs (30% of birds are adult females). Specific population trends are unknown but it is believed that the eastern population of the species declined during the 20th Century and that it may still be declining. These almost entirely ground-based surveys and incidental records were designed to track occurrences of Barrow's Goldeneye and identify important migration,…
