Description

INTRODUCTION The Indiana bat (Myotis sodalis) and northern bat (M. septentrionalis) are syntopic species that form maternity colonies in dead and living trees during summer months in eastern North American forests (Harvey, 1999; Lacki and Schwierjohann, 2001; Gardner and Cook, 2002; Menzel, 2002; Britzke, 2003b). More widely distributed than the Indiana bat, the northern bat occurs in forested habitats throughout the entire distribution of the Indiana bat (Harvey, 1999). Foster and Kurta (1999) compared habitat use between individual populations of these species and hypothesized niche overlap was likely and competition for limited roosting space a possibility when these species occur in the same habitats. These species differ markedly in abundance, population status and conservation priority. The Indiana bat has been listed as federally endangered since 1967 and distribution-wide population sizes continue to remain well below historic levels (US Fish and Wildlife Service, 1999). In contrast, the northern bat is believed to be relatively common throughout much of its distribution forming maternity colonies in both pine and hardwood forests (Lacki and Schwierjohann, 2001; Menzel, 2002; Broders and Forbes, 2004; Perry and Thill, 2007). In this paper we review existing literature describing characteristics of roosting habitat of the Indiana bat and northern bat. We evaluate these data in the context of possible interspecific competition for available roosting space between these species during the summer maternity season.
