British Columbia seabird colony inventory. Report #6, Major colonies on the west coast of Graham Island [electronic resource] / Michael S. Rodway, Moira J.F. Lemon, Gary W. Kaiser. Delta, B.C. : Canadian Wildlife Service, Pacific and Yukon Region, 1994. v, 99 p. : maps.

"The west coast of Graham Island in the Queen Charlotte Islands supports over half a million breeding seabirds of 10 different species. Over 90% of that population is concentrated in three large colonies; on Langara, Frederick and Hippa Islands. The region supports 49% of the total population of Ancient Murrelets nesting in British Columbia. Surveys on the west coast of Graham Island were conducted in 1980, 1981, 1983, 1986, and 1988. Only the major colonies on Langara, Frederick and Hippa islands have been surveyed under the Canadian Wildlife Service inventory program. Baseline population estimates for burrowing species at smaller colonies are lacking. The Ancient Murrelet colony on Langara Island was surveyed in 1981 and again in 1988 to determine population trends and evaluate the impact of introduced mammalian predators. Cox and Lucy islands, which are adjacent to Langara Island and historically supported sizeable colonies, were explored in 1981 to determine their current status"--Abstract, p. i.
