Blue-winged Warbler populations appear stable, but may have declined slightly between 1966 and 2014, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 710,000 with 99% spending some part of the year in the U.S., 32% in Mexico, and 1% breeding in Canada. This U.S.-Canada Stewardship species rates a 13 out of 20 on the Continental Concern Score and are not on the 2014 State of the Birds Watch List. Abandonment of farmlands has increased nesting habitat, but suburban sprawl is decreasing it.Back to top
