    Conservation Low ConcernPacific-slope Flycatcher populations appear stable or slightly declining. The North American Bird Breeding Survey lists these birds together with the very similar Cordilleran Flycatcher, and together the two species' populations showed a small decline between 1966 and 2015. Partners in Flight estimates a global breeding population of 7.4 million birds, with 68% breeding in the U.S., 32% breeding in Canada, and 100% wintering in Mexico. The species rates an 11 out of 20 on the Continental Concern Score, and is a U.S-Canada Stewardship species. Pacific-slope Flycatcher is not on the 2016 State of North America's Birds' Watch List.
