註釋"As part of the Canadian Wildlife Service Seabird Colony Inventory Program we surveyed all colonies between Gillam Islands and McQuarrie Islets, and Cleland Island from 6 to 17 July 1988. Seabird Rocks was surveyed on 26 and 30 July 1988. Colonies south of McQuarrie Islets which were known to support only surface-nesting species were not surveyed. Solander Island was resurveyed on 28 to 30 May 1989 to assess possible impacts to local seabird breeding populations following the Nestucca oil spill, which impacted the west coast of Vancouver Island in January and February of 1989. Results were compared to those obtained in 1988"--Abstract, p. i.
