| Global Habitat Comments: | This species prefers mixed coniferous forests ranging from humid coastal areas to montane forests, and roosting in tree cavities in dense forests, ponderosa pine and lodgepole pine stumps of clear-cut areas, large snags high in or above the canopy, as well as places such as caves, mines, cracks in the ground, abandoned buildings, and loose bark on trees. In the South Saskatchewan River Valley in Alberta, Canada, this species can be found roosting sandstone boulders crevices (IUCN, 2023). | ||||||||||

| Global Range Comment: | Range includes western North America, from southeastern Alaska (north to Skagway), extreme southern Yukon, southwestern Northwest Territories (Nahanni National Park), northeastern British Columbia, southern Alberta, and southern Saskatchewan, south along the Pacific Coast to Baja California, east through Montana and Idaho to the western Dakotas, and from Nevada, Utah, Wyoming and Colorado to New Mexico and Arizona (Manning and Jones 1989, Adams 2003, Reid 2006, Lausen 2006, Alaska Center for Conservation Science 2017, Slough, pers. comm.). Elevational range extends from near sea level along the Pacific Coast to around 2,900 meters in Utah and Wyoming (Manning and Jones 1989, Adams 2003). Misidentifications have somewhat obscured the precise distribution (Johnson and Cassidy 1997, MacDonald and Cook 2009). Reid (2006) incorrectly stated that this species occurs on Wrangell Island, "Siberia." |
