| 520 | 3 |a"In 1993, I conducted studies on two islands in Haida Gwaii (Queen Charlotte Islands) to determine effects of introduced rats on breeding seabirds. The breeding population of ancient murrelets (Synthliboramphus antiquus) on Langara Island declined by approximately 40% between 1988 and 1993 to a level less than 10% of its historical size. The colony covered only about 50% of the area used by murrelets in 1988. Predation on ancient murrelet eggs and adults by Norway rats (Rattus norvegicus) appears to be the primary cause of the colony decline"--Abstract. |
