"The Scott Islands are the most important breeding grounds for seabirds in British Columbia. The outer three islands support over two million breeding birds, comprising 38% of the total seabird breeding population in the province. That dense concentration of breeding seabirds is highly vulnerable to local contamination of the marine environment. Oil from the barge "Nestucca", which was damaged off the Washington coast in late December 1988, spread along the length of the west coast of Vancouver Island in January and February 1989. Almost 13,000 seabirds, mostly Common Murres and Cassin's Auklets were known to have died in Washington and British Columbia. Estimated mortality was 30-40,000 birds. Population studies were conducted on the Scott Islands during the summer of 1989 to assess the impact on local breeding populations. Studies focused on Common Murres and Cassin's Auklets, but information was gathered on other breeding species. Data from all recent surveys by Canadian Wildlife Service were included to provide comprehensive coverage for all species. Results were compared with those from studies conducted in previous years"--Abstract, p. i. Issued also in print format. Includes abstract in French.
