    The big brown bat is one of the larger bat species that frequent the refuge. The females roost in maternity colonies as large as 100 individuals. Refuge research found these roosts are in cavities in snags and dead tops of ponderosa pine, under bark of dead trees and in buildings. They will use several roosts during a breeding season moving every few days.
