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.

Egyptian slit-faced bats form roosting colonies numbering from a few to thousands of other members. Because they can maneuver in crowded habitats, they are able to occupy caves and holes that cannot be accessed by other bat species. [2] While the bats do form a communal roost, individuals do not huddle together to conserve energy and warmth. [6]
Pallid bats are insectivores that feed on arthropods such as crickets, and are capable of consuming up to half their weight in insect every night. Pallid bats are gleaners, capturing prey from the ground and transporting it to their night roost for consumption. When foraging, pallid bats typically fly at low heights of 1–2 m off the ground.
Within the roost the bats quarrel and chatter often, and during sunny hours of the day bats fan their wings and call, and during cloudy periods bats are silent and wrap their wings around their body. Occasionally a few bats fly around the roost during the day, but most activity is restricted to night, when they leave the roost one by one 20 ...
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 ...
Heterothermic bats during long migrations may fly at night and go into a torpid state roosting in the daytime. Unlike migratory birds, which fly during the day and feed during the night, nocturnal bats have a conflict between travelling and eating.
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 ...
The species is very active at night, spending 6–7 hours flying a night for a total distance of about 14.9 miles (24.0 km). [3] Its long, narrow wings allow the bat to maintain flight at high speeds for long periods of time. These bats can reach heights of 196 feet (60 m), though they are also observed flying closer to the ground. [9]
