Comment: Although this is the most common cave bat in the southwest United States, west coast populations inhabit caves 
infrequently (Barbour and Davis, 1969) and are thought to be nonmigratory (Cockrum (1969). However, an emergence 
flight of about 95,000 was observed at Bat Cave No. 1, Siskiyou County, in 2003 (U.S. Geological Survey 2016b), proba¬ 
bly the largest bat colony in the state.
