About This Location
Spencer Island is a 425-acre wetland preserve at the confluence of the Snohomish and Steamboat Slough rivers near Everett, Washington. The island's restored tidal marsh, freshwater ponds, and riparian forest create one of the best birding sites in the greater Seattle area for waterfowl, shorebirds, and marsh birds.
The island is split between a managed wildlife area (north half, owned by Snohomish County) and a natural tidal marsh (south half). The cross-dike trail provides excellent views of both halves. Spring brings returning Osprey, nesting Red-winged Blackbirds and Marsh Wrens, and migrant shorebirds on the mudflats. The marshes host Virginia Rails and American Bitterns, while the riparian edges attract Yellow Warblers and Common Yellowthroats. Bald Eagles nest nearby and are a regular sight year-round.
