1997, Robert Wayne Campbell, Neil K. Dawe, The Birds of British Columbia, Volume 2: Nonpasserines: Diurnal birds of prey through woodpeckers, page 296, About 2,800 pairs of Common Murres breed in the province, most of which are in the Scott Islands off northwestern Vancouver Island.

2000, Susan Allport, The Primal Feast: Food, Sex, Foraging, and Love, 2003, paperback, page 52, Staking out a spot involves not only the appropriate level of murre aggression (some murres are so aggressive that they throw their mates off the ledge) but, even more fundamentally, the ability to find food efficiently.
