Black-throated Sparrow populations declined by over 1.5% between 1966 and 2014, resulting in a cumulative decline of 54%, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 50 million birds with 57% spending part of the year in the U.S., and 66% wintering in Mexico. This U.S.-Canada Stewardship species rates a 9 out of 20 on the Continental Concern Score and is not on the 2014 State of the Birds Watch List. Population declines across the U.S. are attributable to habitat loss due to urban development.Back to top
