"At least 8,800, and probably in excess of 20,000 Common Murres died in British Columbia and Washington during the Nestucca oil spill in January and February 1989. Known mortality exceeded the estimated breeding population in British Columbia. Studies were conducted on Triangle Island, the most important colony in British Columbia, during the summer of 1989, to assess the possible impact on local breeding populations. There was no evidence to indicate that the Nestucca oil spill affected breeding populations in 1989. No dead or oiled murres were observed, and there was no apparent decline in overall numbers at the colony. Reproductive failures on the east side of the island could not be evaluated because of a lack of data from previous years"--Abstract, p. i. Issued also in print format. Includes abstract in French.
