Alder Flycatcher numbers are stable in the U.S. but declined by about 44% in Canada between 1966 and 2014, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 130 million with 24% breeding in the U.S., 76% breeding in Canada, and all of them migrating through Mexico to their wintering grounds in South America. They rate a 7 out of 20 on the Continental Concern Score and are not on the 2014 State of the Birds Watch List, although they are a U.S.-Canada Stewardship species.Back to top
