British Columbia seabird colony inventory. Report #8, Queen Charlotte Strait and Johnstone Strait / Michael S. Rodway and Moira J.F. Lemon. : CW69-5/123E-PDF
"The Canadian Wildlife Service conducted detailed inventories of seabird colonies in Queen Charlotte and Johnstone straits between 1982 and 1987 as part of the British Columbia Seabird Colony Inventory Program. 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 within quadrats surveyed along line transects. Due to time constraints, occupancy rates were not obtained on small storm-petrel (Oceanodroma sp.), Cassin’s Auklet (Ptychoramphus aleuticus) and Rhinoceros Auklet (Cerorhinca monocerata) colonies, and population estimates were based on median occupancy rates at other colonies in the province"--Abstract, p. i.
