Habitat and Ecology [top]

Habitat and Ecology: This species is found in a variety of vegetation types throughout its range, but it is always located near streams, bodies of water or other moist places. Bulldog bats typically roost in hollow trees, foliage and man-made structures. Members of this species have been found in association with the mastiff bat Molossus molossus; the roost can easily be identified by the musky odor of the lesser bulldog bat (Nowak 1999). Natural and urban areas (Barquez 2006, 1999). N. albiventris have been noted foraging with 8-15 conspecifics. Studies of the activity pattern of this species show a peak in activity immediately after sundown (Hooper and Brown 1968).
