Partners in Flight estimates the global breeding population at 400,000, with 69% of these in the U.S., 6% in Canada, and 25% in Mexico. They rate a 12 out of 20 on the Continental Concern Score. The Pacific Northwest population of Western Screech-Owls has proven vulnerable to predation from recently arrived Barred Owls, 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.
