Global Range
F - 20,000-200,000 square km (about 8000-80,000 square miles) - F - The range includes western Washington, British Columbia (including Vancouver Island, the Queen Charlotte Islands, and coastal mainland), and a few localities in southeastern Alaska MacDonald and Cook 2009). This species has one of the smallest distributional ranges of any North American bat (Van Zyll de Jong 1979, 1985). Misidentifications have somewhat obscured the precise distribution (Johnson and Cassidy 1997, MacDonald and Cook 2009). Reid (2009) incorrectly stated that this species occurs on Wrangell Island, Siberia.
