First record on the roosting behaviour of Montane myotis Myotis oxyotus (Chiroptera: Vespertilionidae)

Montane myotis is an Andean bat species whose ecology and roosting behavior is poorly known. Three females were discovered and caught roosting in a crevice in a home’s roof located in Sibundoy Valley (SW Colombia). This is the first roost of Montane myotis ever recorded and evidence that this species, usually caught in forests, may use anthropogenic shelters.
