Ancient Murrelet (Synthliboramphus antiquus) Science Article 2
Ancient Murrelets Synthliboramphus antiquus were nearly extirpated, and five other burrow-nesting species were extirpated from LangaraIsland, British Columbia, following introduction of first Black Rats Rattus rattus and later Norway Rats R. norvegicus. Rats were eradicatedin 1995. To document the apparent response of Ancient Murrelets to introduced rats and to their removal, we compared colony surveys onLangara Island before (1981, 1988, 1993) and after (1999, 2004) rat eradication.
