Aeronautes saxatalis (White-throated Swift)

Wikipedia Abstract

The white-throated swift (Aeronautes saxatalis) is a swift of the family Apodidae native to western North America, south to cordilleran western Honduras. It is migratory, and travels to the southern part of its range in winter, as far north along the Pacific coast as the Californian Central Valley; inland its range extends throughout the Great Basin region to extreme southern British Columbia. Like all swifts, white-throated swifts use their short legs only for clinging onto vertical surfaces or wires, and never land on the ground voluntarily.
