ⓘ Baikal bullfinch
The Baikal bullfinch, also known as the grey bullfinch, is a small passerine bird in the finch family Fringillidae. It is found in eastern Kazakhstan, Mongolia and adjacent areas of Russia and China. Although sometimes considered a full species Pyrrhula cineracea, most authorities treat it a subspecies of the Eurasian bullfinch. It migrates altitudinally from its summer breeding range in the Altai Mountains to its winter range in the adjacent foothills and plains.
