Conservation Common Bird in Steep DeclineGrasshopper Sparrow populations declined by almost 3% per year between 1966 and 2014, resulting in a cumulative decline of 75%, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 31 million with 95% spending some part of the year in the U.S., 53% in Mexico, and 1% breeding in Canada. This U.S.-Canada Stewardship species rates a 12 out of 20 on the Partners in Flight Continental Concern Score. The 2014 State of the Birds Report lists Grasshopper Sparrow as a Common Bird in Steep Decline. The species is declining throughout its range from habitat loss, fragmentation, and degradation.Back to top
