FWS Beringian Seabird 2004

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.

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.

白令海海鸟繁育群落目录（Beringian Seabird Colony Catalog）是由美国鱼类及野生动物管理局（United States Fish and Wildlife Service）迁徙鸟类管理部门在阿拉斯加州安克雷奇维护的、基于地理信息系统（Geographic Information System, GIS）的计算机化数据库。该数据库收录了阿拉斯加州（AK）与俄罗斯（RU）境内海鸟繁育群落的位置与名称、各群落的筑巢鸟类物种，以及各物种的种群数量。

群落编号由地图编号与点位编号两部分组成。地图编号（取值范围1至153）对应美国地质调查局（United States Geological Survey, USGS）1:250000比例尺地形图幅，该编号并非美国地质调查局的官方地图编号。点位编号用于指代特定繁育群落，且在同一地形图幅内不会重复。点位名称优先采用美国地质调查局地图上的官方名称，若无官方名称，则采用自定义描述性名称。
