Conservation
There is little information on Mexican Jay population trends. Though populations are restricted, they appear stable. Partners in Flight estimates a global breeding population of 800,000 with 17% living in the U.S., and 83% in Mexico. The species rates a 12 out of 20 on the Continental Concern Score. Mexican Jay is not on the 2016 State of North America's Birds' Watch List. Back to top
