The Malay cantilever bat ( Emballonura monticola ) is a species of bats within the family smooth-nosed cantilever (Emballonuridae).
It is often confused with the little Asian cantilever bat ( Emballonura alecto ), as both species occur side by side on the island of Borneo .
features
The species reaches a head-body length of 40 to 60 mm and a tail length of 10 mm. The wingspan is 160 to 180 mm. The fur of these bats is brown on the back, lighter colored on the belly side in brown or gray-brown to cream-colored. Often there are reddish shades. The sac-like glands typical of the family occur in all species.
In addition, all species of the family have a flight membrane between their hind paws. The tail protrudes through a small hole in the skin of the hind paws. The bat can move the flexible tail flight membrane ( uropatagium ) back and forth during flight by moving its hind paws . This may improve your flight behavior.
Distribution and habitat
The Malay free-tailed bat occurs from Thailand , Java , Sumatra and Borneo to Malaysia . They can be found in many habitats , such as forests or open landscapes, but especially in rainforest areas. Caves, crevices and cavities of fallen trees are preferably used as resting places.
Way of life
Like most bats, Malay free-tailed bats are nocturnal . When dusk falls, all the animals in a group (approx. Twelve animals) start looking for food at the same time and return around sunrise.
They mostly hunt smaller insects in the treetops and also eat fruits and flowers, where they take on a pollinator role. They fly lower later in the night. The species communicate with high-pitched calls and emit clicks .
Reproduction
The reproductive behavior of these animals is little known and varies between species. Malay free-tailed bats probably do not have a set mating season and they can reproduce all year round. The female only throws one young at a time, which is born after about four months of gestation .
status
In general, Malay cantilever bats are common. The World Conservation Union (IUCN) lists Emballonura monticola as not endangered ( LC ). However, due to the loss of the rainforest habitat, a decreasing tendency can be observed ( decreasing ).
