Conservation

Conservation DecliningOlive-sided Flycatcher declined by over 3.3% per year between 1966 and 2014, resulting in a cumulative decline of 81%, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 1.7 million, with 49% spending some part of the year in the U.S., 2% in Mexico, and 51% breeding in Canada. The species rates a 13 out of 20 on the Continental Concern Score. Olive-sided Flycatcher is a Tri-National Concern species, and 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. Declines may be due to a loss of wintering habitat. Back to top
