In Perspective, Planet: Loss of Billions of Birds in North America!

The Great Gray Owl’s far northern range and elusive habits make it difficult to monitor population trends with surveys like the North American Breeding Bird Survey. Partners in Flight estimates the global breeding population at 190,000, with 7% living in the U.S. and 43% in Canada (with the remainder occurring in Eurasia). The State of North America’s Birds 2016 report rates the species an 11 out of 20 on the Continental Concern Score and it is not on the 2016 State of North America's Birds Watch List. In the United States, Great Gray Owls are at the southern limits of their range and are uncommon, but they are fairly common throughout their
Holarctic range.
