Cordilleran Flycatcher populations appear stable or are slightly declining. The North American Bird Breeding Survey lists these bids together with the very similar Pacific-coast Flycatcher, and together the two species' populations showed a small decline between 1966 and 2015. Partners in Flight estimates a total breeding population of Cordilleran Flycatcher at 3 million, with 70% breeding in the U.S., 2% in Canada, and 100% spending some part of the year in Mexico. The species rates an 11 out of 20 on the Continental Concern Score. Cordilleran Flycatcher is not on the 2016 State of North America's Birds' Watch List.Back to top
