Monitoring Seabird Populations in Areas of Oil and Gas Development on the Alaskan Continental Shelf: Populations, Productivity, and Feeding Habits of Seabirds on St. Lawrence Island

A field camp was established at Kongkok Bay near the southwest cape of St. Lawrence Island and occupied continuously from May 24 to September 2, 1987. Permanent study plots were selected to document attendance patterns, breeding phenology, and success. Periodic collections of adults offshore and of chick meals in the colonies were used to determine the feeding habits of study species. Additional plots for population monitoring of murres and kittiwakes were established in colonies near Savoonga on the north side of the island, and counts were made there between July 23 and August 1. Shore based work was supplemented with offshore studies of seabird foraging distribution from the Fish and Wildlife Service vessel TIGLAX between August 18 and September 3, 1987. Populations of all study species in the Kongkok Bay area increased since the last study of seabirds there (murres 20%, kittiwakes 87%, Least Auklets 8%, Crested Auklets 44%). Pelagic Cormorants, Common Murres, and Thick-billed Murres exhibited average, or above average, breeding success at Kongkok in 1987.
