This site includes the open waters and intertidal zones of Sequim Bay, Washington Harbor, Travis Spit, Gibson Spit, the beaches and bluffs north of Gibson Spit as far north as Marlyn Nelson county park at Port Williams, and the marine waters of the Strait of Juan de Fuca immediately adjacent to the mouth of Sequim Bay. The northern boundary is a line extending from Marlyn Nelson County Park to the base of Travis Spit.

Ornithological Summary

The quiet waters of Sequim Bay are an important refuge for marine birds during periods of severe weather on the Strait of Juan de Fuca. The mouth of the bay is an important foraging area for picivorous birds because the narrow constriction through which the tides must pass concentrates plankton and forage fish. Approximately one of every three years the bay is a staging area for migrating Common Terns. It is also an important foraging area for Red-breasted Mergansers in winter. [NOTE: CBC data show that the numbers of Red-breasted Mergansers often exceed the state threshold of 250 (Bob Boekelheide, personal communication).] The estuarine areas and mudflats in Washington Harbor and at the south end of the bay are important wintering and migration sites for Black-bellied Plover and Dunlin. The jetty at the marina on the west side of the bay is a roosting site for gulls; Heermann?s Gull post-breeding flocks here frequently exceed 100 birds in summer and early fall.
