Nashville Warbler populations are stable, though they may have experienced a small decline between 1966 and 2014 in the U.S., according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 32 million with 19% spending part of the year in the U.S., 81 % in Canada, and 89% in Mexico. They are a U.S.-Canada Stewardship species, and rate a 9 out of 20 on the Continental Concern Score. Nashville Warbler are not listed in the 2014 State of the Birds Report. Clearing of forested land may have benefited this species by creating more of its preferred second-growth habitat.Back to top
