Safety note: May carry rabies — do not approach or handle.

The Tri-colored Bat was one of the first bat species confirmed to be declining severely from White-nose Syndrome, with some hibernacula losing over 90% of their populations within five years of the fungus's arrival. It is a small, early-emerging bat that forages in open areas near streams and forest edges. Recent surveys suggest potential federal Endangered Species Act listing for this species.
