Partners in Flight estimates a global breeding population of 800,000, with 48% spending at least part of the year in the U.S., and 61% in Mexico. The species rates a 9 out of 20 on the Continental Concern Score. Chihuahuan Raven is not on the 2016 State of North America's Birds' Watch List.Back to top
