About This Location
Marymoor Park is King County's largest park at 640 acres, located where the Sammamish River meets Lake Sammamish in Redmond. The park's diverse habitats — including river floodplain, restored wetlands, meadows, and deciduous forest — make it one of the most productive birding sites on Seattle's Eastside.
The Sammamish River corridor attracts spring migrants, with Wilson's Warblers, Orange-crowned Warblers, and Pacific-slope Flycatchers arriving from mid-April. The wetland areas host Virginia Rails, Soras, and Green Herons, while the open meadows attract Savannah Sparrows and hunting raptors. Purple Martins nest in boxes placed along the lake, representing a critical population in western Washington. Winter brings large numbers of waterfowl to the river and lake edges.
