Stephensen, U.S. Fish and Wildlife Service, Division of Migratory Bird Management<br> David Irons, U.S. Fish and Wildlife Service, Division of Migratory Bird Management Abstract: The Beringian Seabird Colony Catalog is a computerized, GIS-based database, maintained by the Division of Migratory Bird Management, United States 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. <br><br> The colony number consists of a map number and a site number. Map number (1 - 153) refers to a United States Geological Survey (USGS) 1:250,000 quadrangle, which is not the same as the 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.

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. <br><br> 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.<br><br> 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.<br><br> An earlier version of this catalog was published (see Sowls et al. 1978). Many data in the 1978 publication have been superseded by this current database, but it is still a helpful reference.
