 Northern long-eared bats are found through much of the eastern half of the United States and Canada from Manitoba and Newfoundland in the north to North Carolina and Alabama in the south.They're also found, but more rarely, in western parts of Canada, sometimes as far as the western borders of British Columbia and Yukon.They are found primarily in forested habitats, especially boreal forests, since they typically roost in hardwood trees during the summer.
