Washington Gap Analysis Project's Predicted Distribution Map

Arctic Tern (Sterna paradisea)

Legend: = Core Habitat = Marginal Habitat Breeding Range Map The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, Breeding Bird Atlas (BBA) ,other datasets and experts throughout the state, as part of the Washington Gap Analysis Project. Habitats used during non-breeding months and migratory rest-stops were not mapped.

Metadata (Data about data or how the map was made)

This species is a very local breeder in western Washington at Everett in Snohomish County.

No habitat was modeled for this bird. It was not known as a breeder until 1977, when a small colony was found on Jetty Island in Everett, 825 miles from the nearest neighbor in southeastern Alaska. The colony moved to an adjacent parking lot at the west end of 13th Street in Everett in the early 1980s, after vegetation had grown up on Jetty Island. The terns used this site until 1995, when the Navy successfully discouraged nesting. Efforts to manicure habitat for this species on Jetty Island have apparently failed so far. Cape Cod is the southernmost known breeding site for this species in North America.
