Prairie Warbler is declining throughout most of range. The North American Breeding Bird Survey estimates a loss of almost 2% per year between 1966 and 2014, resulting in a cumulative decline of 66% during that time. Partners in Flight estimates a global breeding population of 3.5 million birds, with 100% spending part of the year in the U.S., and 3% in Mexico. It rates the species a 13 out of 20 on the Continental Concern Score. Prairie Warbler is both a Tri-National Concern Species, and a U.S.-Canada Stewardship species. It is on the 2014 State of the Birds Watch List, which lists bird species that are at risk of becoming threatened or endangered without conservation action. Population declines are largely attributable to loss of breeding habitat through development and natural change of shrubby habitat to forest. Back to top
