Beringian Seabird Colony Catalog (2004)Entry ID: seamap270
Abstract: The Beringian Seabird Colony Catalog is a computerized, GIS-based database, maintained by the Division of Migratory Bird Management, U.S. Fish and Wildlife Service, in anchorage, Alaska. It contains the locations and names of seabird breeding colonies in Alaska (AK) and Russia (RU), the species of birds that nest in each colony, and the numbers of each species. The colony number consists of a map number and a site number. Map number (1 - 153) refers to a USGS 1:250,000 quadrangle, which is not the same as official USGS map number. A site number refers to a specific colony and is not duplicated within the quadrangle. The site name is derived from an official name on USGS map, if one exists; otherwise a descriptive name was invented.
Purpose: We count birds in some colonies (or in parts of the colonies) each summer. This tells us whether the birds' populations are healthy. If a population is getting smaller, we study it and try to learn what the problem is. In the area that was affected by the Exxon Valdez oil spill, we study seabirds to learn whether they are recovering from the oil. We count the birds in winter and summer. We study ... how many eggs the birds lay and how many young birds they raise each summer. We also study how they find their food at sea. We work with observer programs to learn how many birds are caught in fishing gear. This tells us whether seabird breeding populations are impacted by fisheries bycatch.
