Abstract
Auks (Alcidae) form an important component of marine avifaunas in the Northern Hemisphere, in terms of numbers of both individuals and species. In order to effectively manage and protect alcid populations, basic demographic data are vital (Nisbet 1979). Demographic parameters have been estimated for five of the six species in the North Atlantic (Hudson 1985). In contrast, survivorship of banded birds is known for only one Pacific Ocean alcid species (Ancient Murrelet, Synthliboramphus antiquus, Gaston 1990). In this note, I report survivorship and recruitment of a color-marked sample of Pigeon Guillemots (Cepphus columba) over a five-year period.
