| ? Big Brown Bat |
A big brown bat approaches a wax moth (Galleria mellonella), which serves as the control species for the studies of the tiger moths. The moth is only "semi-tethered," allowing it the mobility to fly evasively. | | Scientific classification | | | | | | Eptesicus fuscus
(Palisot de Beauvois, 1796) | | | The Big Brown Bat Eptesicus fuscus, is larger in size than comparitive species of bats, from about 4 to 5 inches (10 - 13 cm) in length and weighing 1/2 to 5/8 ounce. The fur is moderately long, and shiny brown. The wing membranes, ears, feet, and face are dark brown to blackish in color.

Big brown bats are nocturnal, roosting during the day in hollow trees, beneath loose tree bark in the crevices of rocks or man-made structures, such as attics, barns, old buildings, under eaves and behind window shutters. Big brown Bats navigate through the night skies by use of echolocation, producing ultrasonic sounds through the mouth or nose. Together with the Hoary Bat (Lasurius cinereus), big brown bats are the only vespertilionids to produce audible sound during flight. Its voice is a click or a sound like escaping steam. A nocturnal animal is one that sleeps during the day and is active at night - the opposite of the human (diurnal) schedule. ...

Ultrasound is sound with a frequency greater than the upper limit of human hearing, approximately 20 kilohertz. ...
Big brown bats are insectivorous, eating many kinds of night-flying insects including beetles and wasps which they capture in flight. This causes the sudden, frequent changes in direction. Any organism with a diet that consists chiefly of insects and similar small creatures is an insectivore. ...
Big brown bats hibernate during the winter months, often in different locations than their summer roosts. Winter roosts tend to be natural subterranean locations such as caves and underground mines where temperatures remain stable; it is still unknown where a large majority of big brown bats spend the winter. If the weather warms enough, they may awaken to seek water, defecate, and even breed. Subterranean can also refer to something below the Earths surface Subterranean was an album released by Swedish heavy metal band In Flames in 1995. ...
Big brown bats mate sporadically from November through March. After the breeding season, pregnant females separate themselves into maternity colonies. Maternity colonies are most likely to occur in man-made environments such as the attics of buildings and other similar locations since female bats tend to choose areas with high daytime temperatures in which to raise their young.
The young bats, averaging two to a litter, are born in late May or early June. The baby bats are nursed in the roost and then left there in the evenings while the females fly out to feed. When the young are between three and four weeks of age, they begin to leave the roost for their first flights. Big brown bats are a long-lived species, with some specimens having lived for as long as 18 years.
