Vespertilio subulatus keenii

Canada, British Columbia, Queen Charlotte Islands [= Haida Gwaii], Massett

United States (SE Alaska and NW Washington) and British Columbia (including Haida Gwaii and Vancouver Isls; Canada)

CITES - Not Listed IUCN - Least Concern (2017).

Does not include septentrionalis; see van Zyll de Jong (1979) and Caceres and Barclay (2000). See Fitch and Shump (1979), but note that they included septentrionalis. There remains spirited debate over the status of keenii (see e.g, Nagorsen and Brigham, 1993; Van Zyll de Jong and Nagorsen, 1994; Nagorsen, 2002; Lung et al., 2013; Lausen et al, 2019; Morales et al., 2021; Lausen et al., 2021). For a summary of these issues, and to explain our decision to recognize keenii as a distinct species, see Upham and Francis (2022).
