Abstract: Barrow’s Goldeneye (Bucephala islandica) were counted at Castlegar, British Columbia eight times from 2011 November through 2012 April. Approximately 600 Barrow’s Goldeneye wintered at the confluence of the Columbia and Kootenay rivers within an area equivalent to seven river kilometres, giving a linear density of about 86 birds per kilometre. Comparisons with numbers reported elsewhere demonstrate that this is possibly the highest wintering concentration of the species in the B.C. interior.
