Gray-headed Chickadee is certainly one of the most enigmatic species of breeding birds in the ABA Area. Though it is found broadly across northern Eurasian it was, until very recently, also known from an isolated breeding population in northern Alaska and far northwestern Canada. Those bird, long a bucket list objective for ABA Area birders, might be gone, and the reasons for that are unclear. Alaska birder and conservationist Brad Meiklejohn explores their disappearance in the Lost on the Frontier: The Mysterious Disappearance of North America's Rarest Breeding Bird, published in the July 2025 issue of Birding magazine, and he joins us to talk more about this avian mystery. Stay tuned for a publicly accessible version of this article. Also, the auction featuring some of our past Bird of the Year cover art is up and running!
