Recent Distribution Records of the Little Brown Bat, Myotis lucifugus, in Manitoba and Northwestern Ontario

John E. Dubois, Kimberly M. Monson


Until recently, the distribution of the Little Brown Bat (Myotis lucifugus) in Manitoba and northwestern Ontario was poorly documented. Since 1988, we have been banding and recapturing little browns throughout Manitoba and adjacent Lake of the Woods region in Ontario. All known hibernacula in the study area are recorded here for the first time, along with time of emergence. Connections between some hibernacula and summer nurseries are verified by band returns, ranging from 37 to 540 km.
