In Eurasia, \u201cTengmalm\u2019s Owl\u201d is resident essentially throughout the taiga belt from Scandinavia east to Chukotka, the Kamchatka Peninsula, and Sakhalin.\u00a0 Also occurs southward in coniferous forests of continental Europe (south to the Pyrenees, the Alps, and northern Greece) and central Asia (from Tajikistan to northern Xinjiang).<\/p>

More isolated, little-reported populations inhabit mountains of northwestern Turkey, the Caucasus region (Georgia, Armenia, and northeastern Turkey), north-central Iran, the western Himalayas (e.g., two specimens collected in Himachal Pradesh in 1936 and multiple photographs from Gilgit-Baltistan in 2022), central China (Gansu), and Hokkaido.<\/p>

In North America, \u201cRichardson\u2019s Owl\u201d is resident from central Alaska east through forested regions of Canada to Newfoundland, and locally south in several mountain ranges into the western U.S., including the Cascades (to southwestern Oregon), the Blue Mountains, the Wasatch, and the Rockies (to northern New Mexico).<\/p>

All populations appear to be mostly sedentary overall, with some regular dispersal in fall and winter.\u00a0 Localized irruptions have occurred in some winters, resulting in numerous records south of the usual range in the Great Lakes region, New England, and the Maritime Provinces, and west of the usual range in continental Europe.<\/p>

Exceptional vagrants have been recorded as far afield as Nebraska, Iowa, New York City, Long Island, Nantucket, the Shetlands, Scotland, St. Lawrence Island, and the Pribilofs.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
