Forest Edge Wildlife Control (413)-695-0606
Eptesicus fuscus (Beauvois)Big Brown Bat
Adult total length: 3 3/4 - 5 1/8 in. (94 - 130 mm)
Tail: 1 3/8 - 2 1/8 in. (35 - 52 mm)
Hind foot: 3/8 - 1/2 in. (10 - 11.5 mm)
Weight: 6/10 - 7/10 oz. (14 - 21 g)
Physical Characteristics: Bats are unique among mammals because their forelimbs are specialized for true flight. Flight membranes, which are actually extensions of the skin of the back and belly, connect the body with the wings, legs, and tail. Unlike birds, bats use both legs and wings during flight. Other modifications for flight include greatly elongated fingers to provide support for the wing membrane, a keeled sternum for the attachment of the enlarged flight muscles, and fusion of some vertebrae. The membrane extending from the tail to the hind legs is known as the interfemoral membrane. The big brown bat is one of the largest bats in the park. It has a wingspan of approximately 12 inches (305 mm). Along with its size, it can be distinquished from all bats in the park by its long, uniformly dark brown fur. The fur of the undersurface is paler. The blackish ears are short, broad, and rounded and barely reach the nostrils when laid forward. The top of the blackish interfemoral membrane is naked except for a sprinkling of hairs on the basal fourth.
Habitat
All of the park's caves provide critically important habitats for bats. During the summer, these bats are usually found in attics, barns, and bridges. During the coldest weather, these bats move into caves and mines. Big brown bats usually hang alone while hibernating, although small clusters of fewer than 20 bats also occur. The big brown bat mainly hibernates in buildings with only a few individuals overwintering in caves.
Reproduction
Maternity colonies of the big brown bat containing up to several hundred individuals form during the summer. Females store sperm in their reproductive tracts during the winter and ovulate in early spring, at the time of arousal from hibernation. Following a gestation period of 60 days, breech birth occurs. Eighty percent or more of females in eastern North America produce twin pups, but litter size in the West is generally one. Young are born weighing an average of 3.3 g and learn to fly at 18-35 days of age.
Terrestrial Ecology
The senses of sight and hearing are well developed in bats. Since most bats become active near dusk and are active much of the night, sight is of little importance in navigation and in the capture of prey. Instead, they use echolocation, a system somewhat similar to radar. They emit ultrasonic calls far above the range of human hearing that are reflected from objects ahead of them. They hear the echoes and are able to avoid obstacles and find food in total darkness. Different species can be distinguished by differences in the structure of their echolocation
