Summary
Description
This study was conducted in June 1987 on Adak Island, Alaska, at two sites in the Clam Lagoon area. The primary objectives of the Aleutian tern Sterna aleutica study were to delineate colony boundaries, determine the population size of the colony, determine activity periods and nesting phenology, develop methods that can be repeated in future years and record all abnormal disturbances. The Aleutian tern is a summer visitor to Adak Island, arriving in late May and departing in mid to late August.
