Keenís Long-eared Myotis (Myotis keenii) is restricted to the coastal forests of the United States and Canadian Pacific Northwest, and has one of the smallest geographical ranges of any North American species of bat. It is also one of the most poorly studied. Virtually nothing is known about even its basic biology. In a field survey of coastal British Columbia conducted during summer 1991, we captured (and released) 29 M. keenii at a nursery colony discovered among geothermally heated boulders on Hot Spring Island (Gaandl Kin) in the Queen Charlotte Islands (Haida Gwaii). This is the first record of a maternity colony for the species. In addition, nine long-eared bats were caught on Vancouver Island and the mainland. Two of these were identified as Myotis evotis; however, we were unable to unambiguously identify the others as either M. keenii or M.evotis due to the inadequacy of previously used external characteristics for identification. Despite this, it is evident that M. keenii is not common. Based almost
