There is little information on Saltmarsh Sparrow population trends, but the species is declining, and it is listed on the 2016 State of North America's Birds' Watch List, which includes bird species that are most at risk of extinction without significant conservation actions to reverse declines and reduce threats. Partners in Flight estimates a global breeding population of 75,000, with 100% living in the U.S.. The species rates a 19 out of 20 on the Continental Concern Score. It is both a Tri-National Concern Species, and a U.S.-Canada Stewardship species. Saltmarsh Sparrow is listed as Vulnerable on the IUCN Red List. The species is threatened by habitat loss due to development, habitat degradation from chemical spills and other pollutants, invasive species, and sea level rise. Back to top
