Vaux's Swift declined across most of its range by almost 2% per year between 1966 and 2014, resulting in a cumulative decline of 57%, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 600,000, with 41% spending some part of the year in the U.S., 52% in Mexico, and 14% breeding in Canada. The species rates an 11 out of 20 on the Continental Concern Score. Vaux's Swift is not on the 2014 State of the Birds Watch List. Logging of large-diameter trees in old-growth forests eliminates nest sites.Back to top
