Miniopterus schreibersii has a body length of 52 to 63 mm, a tail length of 50 to 60 mm, and a forearm length of 42 to 48 mm. Its color ranges from grey to yellowish brown (Grzimek, 1990).
Miniopterus schreibersii is a medium sized bat with extremely long fingers and correspondingly broad wings (Grzimek, 1990). The second bone of the longest finger is about three times as long as the first bone. When hanging by its hind feet, this lengthened terminal part of the third finger folds back on the wing (Nowak, 1997).
The body hairs of M. schreibersii stand erect. A small tragus is visible in the ears. This species has a short snout and hairs projecting form the upper surface of the head (Grzimek, 1990). The tail of M. schreibersii is completely enclosed within the interfemoral membrane and is proportionately longer than in many other bats of the same size (Nowak, 1997).
Range mass: 8 to 11 g.
Range length: 52 to 63 mm.
Other Physical Features: endothermic ; bilateral symmetry
M. schreibersii has been found to roost in caves, rock clefts, culverts, caverns, and galleries (Grzimek, 1990; Nowak, 1997).
Studies of this species in India showed that the population of a given area tended to be centered in one large cave but that individuals spent part of their time in secondary roosts within a 70 km radius (Nowak, 1997).
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: savanna or grassland ; mountains
Other Habitat Features: caves
Habitat and Ecology

Miniopterus schreibersii feeds on small beetles and insects. Feeding usually occurs at heights of 10 to 20 meters (Norak, 1997; Grzimek, 1990). Insects are caught by using echolocation.
Primary Diet: carnivore (Insectivore )
Life History and Behavior
Perception Channels: tactile ; chemical
Lifespan, longevity, and ageing
These bats reach sexual maturity at the age of one year (Grzimek, 1990). In a study in eastern Australia by Richardson (1977) they were found to be monestrous. Mating took place in the fall (late May to early June), with fertilization and development to the blastocyst stage immediately following. Implantation was delayed until August and births occurred in December. Each female usually has one offspring (Nowak, 1997).
The young are weaned at from 7 to 9 weeks of age. After the young are weaned females are once again ready for breeding (Grzimek, 1990; Nowak, 1997).
Breeding interval: These bats apparently breed once per year.
Breeding season: Mating occurs from late May to early June.
Range number of offspring: 1 to 2.
Average gestation period: 240 days.
Range weaning age: 42 to 90 days.
Average weaning age: 52.5 days.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous ; delayed implantation

Public Records: 8
Specimens with Barcodes: 21
Species With Barcodes: 1
Miniopterus schreibersii is on the IUCN red list for low risk, near threatened species. However, it is not on the CITES or U.S. ESA lists.
This species is mainly endangered in western Europe but possibly through out the world. Colonies that had contained thousands of individuals have disappeared. Miniopterus schreibersii is especially sensitive to disturbances and may be locally eradicated if disturbed by human workers or tourists (Nowak, 1997). Destruction of habitat is a serious threat to these animals.

Extinction has occured in Germany and Ukraine. In Switzerland the species has declined since the 1960s and it is now close to extinction, and in Austria the hibernating population has declined from 2,500 to 1-2 individuals and all maternity colonies have been lost. In Romania, half of the roosts have disappeared since the 1960s. However, no decline has been recorded in large colonies in Croatia and Bulgaria. In 2002 mass mortalities of this species were reported for populations in France, Spain and Portugal; there are also historical records for such mortalities in Italy. A herpesvirus was found but not identified as the cause of the die offs. Hundreds of individuals were found dead in spring. Mortality up to 60% in one year (2002) was reported in France (Roué and Némoz 2002), and 40% mortality occurred in Spain during the same period including 1,000 dead individuals out of 6,000 in one colony. A number of sites were subsequently deserted. Outside Europe, it is the third most common bat species in Turkey, with large colonies of thousands of individuals (A. Karatas pers. comm. 2005). Populations in the Caucasus are considered Near Threatened (K. Tsytsulina pers. comm. 2005).
The cause of recent mass mortality events is unknown. In 2002 mass mortalities of this species were reported for populations in France, Spain and Portugal. There are also historical records for such mortalities in Italy, Australia and a possible incidence in Iran. A meeting was held at the 9th European Bat Conference to discuss these incidents. Veterinary investigations in Spain did not identify any disease as the cause of the die offs, and there is increasing belief that the die offs are caused by bad weather in late winter/early spring.
The species is found in many protected areas throughout its range.
Care is required when fencing caves to minimise mortality. Further research is required into the causes of the recent mass mortality events.
Relevance to Humans and Ecosystems
Bats can be extremely benefitial to humans. They eat many of the insects and pests that plague farmers and gardeners. This helps keep insects from over populating an area and it reduces the amount damage done to crops by these insects.
Positive Impacts: controls pest population
Change in quality.

Common bent-wing bat
The common bent-wing bat, Schreibers' long-fingered bat, or Schreibers' bat (Miniopterus schreibersii) is a species of vesper bat in the family Vespertilionidae. It is a species of subtropical origin distributed throughout the southern Palearctic, Ethiopic, Oriental, and Australian regions. In Europe, it is present in the southern half from Iberia to the Caucasus, with the largest populations found in the warmer Mediterranean area.
The common bent-wing bat is a bat that forms major colonies and the longest period of torpor (hibernation) observed was about 12 days. These colonies can range anywhere from a few dozen or several million bats. Most of these colonies are formed in large caves or mines but they can also be found in other areas such as tunnels or ruins or other man made sites. In these roosting sites the common bent-wing bat establishes its colony in a "bell-shaped" hollow, which traps body heat and raises the temperature of the roost higher than the surrounding portions of the cave. This method of trapping warmth is used to reduce energy loss from shivering. Also, they will often enter hollows through small openings in order to better secure themselves from large predators during torpor. The common bent-wing bat migrates multiple times a year depending on weather of the roosting area; the length of these migrations can vary but the longest migration recorded was 833 km.
The common bent-wing bat is categorized as "Near Threatened" according to the International Union for Conservation of Nature. The explanation for the recent cause of these deaths is unknown but there have been many speculations as to why the mortality rate for this bat has increased. Researchers in Europe believe that the loss of underground habitats, the disturbance of their habitats, and pesticide use has caused an increase in deaths for the common bent-wing bat. In Australia researchers suspect that the high tissue levels of DDT (Dichlorodiphenyltrichloroethane) they found in the common bent-wing bat, including the young ones that had not left the maternity roosts, was the cause of these deaths.
The common bent-wing bat can be found in the following countries:Afghanistan, Albania, Algeria, Armenia, Australia, Austria, Azerbaijan, Bosnia and Herzegovina, Bulgaria, Cameroon, China, Croatia, Republica Dominicana, possibly Ethiopia, France, Georgia, Gibraltar, Greece, Guinea, Hungary, India, Indonesia, Iran, Iraq, Israel, Italy, Japan, Jordan, possibly Kenya, North Korea, South Korea, Laos, Lebanon, Liberia, Libya, Republic of Macedonia, Malaysia, Malta, Montenegro, Morocco, Myanmar, Nepal, Nigeria, Pakistan, Palestine, Papua New Guinea, Philippines, Portugal, Romania, Russian Federation, San Marino, Saudi Arabia, Serbia, Sierra Leone, Slovakia, Slovenia, Solomon Islands, Spain, Sri Lanka, Switzerland, Syrian Arab Republic, Taiwan, Tajikistan, Thailand, Tunisia, Turkey, Turkmenistan, Vietnam, and Yemen.
