5203 |a"The Canadian Wildlife Service conducted detailed inventories of seabird colonies along the northern mainland coast in 1983, 1987 and 1988 as part of the British Columbia Seabird Colony Inventory Program. All colonies of burrow-nesting species were surveyed. A few small gull colonies were not visited. Total or partial counts were made for surface-nesting species and small colonies of burrow nesters. Burrow densities on larger storm-petrel and alcid colonies were estimated using systematic sampling along strip transects or within quadrats surveyed along line transects. Burrow occupancy rates were not obtained at small storm-petrel and alcid colonies, and population estimates were based on median occupancy rates at other colonies in the province"--Abstract, p. i.
