This species is represented by very few occurrences or subpopulations. All of the known occurrences are relatively small and probably of less than optimal viability, yet they probably have a good probability of persistence for the foreseeable future. This species has appeared to exist in low numbers for several decades (Timm and Genoways 2004). Total adult population size is unknown. The species appears to be rare but may be more numerous than historical evidence indicates (USFWS 1996). It roosts singly or in small groups.
