While there are few observations of communal roosting mammals, the trait has been seen in several species of bats. The little brown bat (Myotis lucifugus) is known to participate in communal roosts of up to thirty seven during cold nights in order to decrease thermoregulatory demands, with the roost disbanding at daybreak. [26]
The species forages with a rapid flying speed of 20–40 km/h (12–25 mph), sometimes up to 60 km/h (37 mph). [2] Because of temporally limited availability of insect prey, they have short daily activity periods before sunrise and after sunset of in total one hour or less and so must cope with up to twenty-three hours of fasting a day.

While the bats do form a communal roost, individuals do not huddle together to conserve energy and warmth. [6] They occupy two roosts, using the daytime roost to rest, while only spending a few hours in the night roost before going out to forage. [7] They have a long-night foraging period, lasting several hours. [6]
The common vampire bat (Desmodus rotundus) is a small, leaf-nosed bat native to the Americas. It is one of three extant species of vampire bats, the other two being the hairy-legged and the white-winged vampire bats. The common vampire bat practices hematophagy, mainly feeding on the blood of livestock. The bat usually approaches its prey at ...
Groups of C. perspicillata will roost in numbers from 10 to 100, in caves, hollow trees, and in tunnels. [3] They will usually roost during the day, and will forage at night. [3] There are two different types of roosts found in these bats, harems and bachelor roosts. [3] In a harem roost, there is a single male, some females and their offspring ...

A night roost is usually less protected than a day roost; open porches may be used as night roosts by this species. In the winter time, this species may dip into shallow bouts of torpor, often in buildings, caves, or cracks in rocks. [1] Pallid bats are insectivores that feed on arthropods such as crickets, and are capable of consuming up to ...
