Black Swift Cypseloides niger

Fairly common but local in Cascades on both sides of crest. No "confirmed" records in BBA period but known to nest on inaccessible cliffs, usually behind waterfalls. Mapped records limited to birds foraging aerially in Cascades and foothills, although birds frequently observed in lowlands as well. Clusters of records perhaps indicative of nearby nesting include Green River Valley above Howard Hanson Reservoir, South Fork Skykomish drainage from Baring to Stevens Pass, high Cascades north from Snoqualmie Pass, Gold Creek Valley, upper Kachess River, upper Cle Elum River, North Fork Teanaway River, and Lookout Mountain/Windy Pass vicinity.
