Blackburnian Warbler populations are stable. Partners in Flight estimates a global breeding population of 10 million birds with 28% spending some part of the year in the U.S, 72% in Canada, and all of them migrating through Mexico on the way south to their wintering grounds. They are a U.S.-Canada Stewardship species and rate a 9 out of 20 on the Continental Concern Score. They are not on the 2014 State of the Birds Watch List. Back to top
