Major seabird colonies in tlie Bering Sea. The adjacent Big Diomede Island has vast but un- known numbers of seabirds. These colonies are less diverse than the outer-shelf colonies; zooplank- ton-eating seabirds make up at least 88 percent of the communities. The seabird colonies on St. Lawrence are concen- trated on the western end of the island. Although talus slopes and cliffs are available at the eastern end of the island, this end supports few seabirds. Those few that do nest there are fish-eating species typical of the coastal colonies. The zooplanktivorous Least Auklets are almost entirely absent. This difference between the communities of the eastern and western ends of St. Lawrence Island reflects the different character of the waters at the two locations. The eastern end of the island is bathed in Alaska coastal water, neritic waters strongly influenced by fresh- water flow from the Yukon River (Coachman et al. 1975). In contrast, the west end of St. Lawrence Is- land is influenced by currents transporting water and plankton from deep oceanic waters (T. Kinder, NORDA, personal communication). King Island lies 72 km off the mainland between Norton Sound and Port Clarence. King Island is in- fluenced by the oceanic currents flowing northward to the Bering Strait, even though the island lies within the coastal regime. Consequently, the seabird com- munities on the island have both "coastal" species such as Common Murres and Parakeet Auklets and "oceanic" species like Least and Crested Auklets.
