Devon Bat Group
The Devon Bat Group (DBG) was founded in 1984 to help protect bats and their habitats, to look after injured bats and to advise and educate people about bats. History The Devon Bat Group was formed in the English county of Devon in 1984 by people concerned about the decline of British bats. Devon, in the South West of England, is of special importance as it supports most of the British bat species and DBG members work to maintain this diversity and increase our knowledge about bats. It is one of a network of bat groups in the UK which are members of The Bat Conservation Trust. The Bat Conservation Trust was formed in 1991 as an umbrella organisation for the network of bat groups in the UK. Group members and activities The Group members range from people who are interested in learning more about bats and those wanting to join in group activities to professional ecologists. Activities include roost visits, organising bat box schemes, with regular box checks, and bat survey ...

Pipistrellus Pipistrellus Lateral
''Pipistrellus'' is a genus of bats in the family Vespertilionidae and subfamily Vespertilioninae. The name of the genus is derived from the Italian word , meaning "bat" (from Latin "bird of evening, bat"). The size of the genus has been considerably reduced as a result of work during the 1990s and 2000s, with genera such as ''Arielulus'', ''Hypsugo'', ''Falsistrellus'', ''Neoromicia'', ''Parastrellus'', '' Perimyotis'', ''Scotozous'', and ''Vespadelus'' being split off. Still, molecular evidence suggests the genus is not monophyletic. Several other genera in the subfamily Vespertilioninae have also been merged with ''Pipistrellus'' in previous classifications. Species in the genus may be referred to as "pipistrelles" or "pipistrelle bats", though these terms are also used for species now placed in other genera, such as the western pipistrelle (''Parastrellus hesperus'') and eastern pipistrelle (''Perimyotis subflavus'') of North America. Species of the southern hemisphere sep ...

Barbastella Barbastellus
The western barbastelle (''Barbastella barbastellus''), also known as the barbastelle or barbastelle bat, is a European bat in the genus '' Barbastella''. This species is found from Portugal to Azerbaijan and from Sweden to Canary Islands, where a sub-species was identified. It has a short nose, small eyes and wide ears. The conservation status of ''B. barbastellus'' is assessed as "near threatened", "vulnerable", "critically endangered" or "extinct" in various parts of its range. Taxonomy The western barbastelle was described as a new species in 1774 by Johann Christian Daniel von Schreber, who placed it in the genus ''Vespertilio'', with a species name of ''Vespertilio barbastellus''. The holotype had been collected in Burgundy, France. In 1836 it was placed in the genus ''Barbastellus'', and the first use of its current name combination of ''Barbastella barbastellus'' was in 1897 by Gerrit Smith Miller Jr. The name ''Barbastella barbastellus'' might be coming from the ...

Plecotus Austriacus
The grey long-eared bat (''Plecotus austriacus'') is a fairly large European bat. It has distinctive ears, long and with a distinctive fold. It hunts above woodland, often by day, and mostly for moths. In captivity, it has also been recorded to eat small lizards. It is extremely similar to the more common brown long-eared bat, and was only distinguished in the 1960s, but has a paler belly. Biology and ecology Its main foraging habitats are lowland meadows and marshes. It locates its insect prey via echolocation. The frequencies used by this bat species for echolocation lie between 18–45 kHz, have most energy at 28 kHz and have an average duration of 5.8 ms. Distribution Distributed throughout all of Europe, except for the Scandinavian Peninsula. Conservation It is currently listed as near-threatened by the IUCN. It has a large geographic range and it is considered relatively common. In most of the countries where it is found, it is protected from intenti ...

Pipistrellus Pygmaeus
The soprano pipistrelle (''Pipistrellus pygmaeus'') is a small species of bat. It is found in Europe and often roosts on buildings. Taxonomy Until 1999, the soprano pipistrelle was considered as conspecific with the common pipistrelle The common pipistrelle (''Pipistrellus pipistrellus'') is a small pipistrelle microbat whose very large range extends across most of Europe, North Africa, South Asia, and may extend into Korea. It is one of the most common bat species in the Brit .... It is possible that these two species diverged from one another in the Mediterranean, resulting in the Soprano pipistrelle having the ability to thermoregulate at temperatures as high as 40 degrees Celsius. Since the two species were split, a number of other differences, in appearance, habitat and food, have also been discovered. The two species were first distinguished on the basis of the different frequency of their echolocation calls. The common pipistrelle uses a call of 45 kHz, while the s ...

Pipistrellus Pipistrellus
The common pipistrelle (''Pipistrellus pipistrellus'') is a small pipistrelle microbat whose very large range extends across most of Europe, North Africa, South Asia, and may extend into Korea. It is one of the most common bat species in the British Isles. In Europe, the northernmost confirmed records are from southern Finland near 60°N. In 1999, the common pipistrelle was split into two species on the basis of different-frequency echolocation calls. The common pipistrelle uses a call of 45 kHz, while the soprano pipistrelle echolocates at 55 kHz. Since the two species were distinguished, a number of other differences, in appearance, habitat and food, have also been discovered. Taxonomy and etymology It was described as a new species in 1774 by German naturalist Johann Christian Daniel von Schreber. Schreber initially placed it in the genus ''Vespertilio'', calling it ''Vespertilio pipistrellus''. In 1839, Keyserling and Blasius reclassified the species, naming ...

Pipistrellus Nathusii
Nathusius' pipistrelle (''Pipistrellus nathusii'') is a small bat in the genus ''Pipistrellus''. It is very similar to the common pipistrelle and has been overlooked in many areas until recently but it is widely distributed across Europe. It was described by two German naturalists, Alexander Keyserling and Johann Heinrich Blasius, and named by them after Hermann von Nathusius, in gratitude for his support of their research. Description The length of the head and body is 46–55 mm and the wingspan is 220–250 mm. It has a forearm length of 32–40 mm and weighs about 6–15.5g. The fifth finger is longer than 43 mm. Its fur is medium-dark reddish-brown above, often with paler tips, and is pale brown below. The fur is longer and less uniformly-coloured than the common pipistrelle. It is also larger than the common pipistrelle with broader wings. The face, ears, wings and tail are dark. Distribution Nathusius' pipistrelle occurs from Western Europe eastward a ...

Nyctalus Noctula
The common noctule (''Nyctalus noctula'') is a species of insectivorous bat common throughout Europe, Asia, and North Africa. Description The common noctule's short fur is dark brown after moulting in June (males) or July/August (females); later it changes to red-brown before the onset of winter.Braun M. & Dieterlen F. 2003 When awake, the body temperature is but it decreases significantly during inactivity. The body mass of adult common noctule is and they have a wingspan of . The species forages with a rapid flying speed of , sometimes up to . Because of temporally limited availability of insect prey, they have short daily activity periods before sunrise and after sunset of in total one hour or less and so must cope with up to twenty-three hours of fasting a day. Distribution Most parts of Europe, central Russia, across the Ural mountain, Caucasus, Turkey, the Near East, to southwestern parts of Siberia, the Himalayas, China, Malaysia, Taiwan and Japan. In Bulgaria, it is ...

Myotis Nattereri
Natterer's bat (''Myotis nattereri'') is a European vespertilionid bat with pale wings. It has brown fur tending to greyish-white on its underside. It is found across most of the continent of Europe, parts of the Near East and North Africa. It feeds on insects and other invertebrates which it catches on the wing or pursues on the ground. In summer it roosts in deciduous and coniferous trees, buildings or bat boxes close to its feeding habitats. In winter it hibernates in caves, tunnels, mines or cellars, usually hiding in crevices. This bat was first described in 1817 by Heinrich Kuhl, who named it in honour of the Austrian naturalist Johann Natterer. Description Natterer's bat is a medium-sized species and grows to a head and body length of with a forearm (elbow to wrist) length of . It weighs between .

Myotis Mystacinus
The whiskered bat (''Myotis mystacinus'') is a small European bat with long fur. Although uncommon, ''M. mystacinus'' is often found around human habitation and around water; it is similar to Brandt's bat (''Myotis brandtii''), from which it was distinguished as a separate species only in 1970. Overview The analysis of morphological, behavioural, and especially genetic characters have since identified further cryptic species of whiskered bats in the genus ''Myotis'', including ''Myotis alcathoe The Alcathoe bat (''Myotis alcathoe'') is a European bat in the genus ''Myotis''. Known only from Greece and Hungary when it was first described in 2001, its known distribution has since expanded as far as Portugal, England, Sweden, and Russia. I ...''
