In 2014 and 2015 they helped to run a citizen science project called The Big Exeter Bat Survey to find out about where (and which) bats live in Exeter. [6] As part of the work to re-open Hemerdon Mine, survey data from the group were used as evidence to draw up a plan to mitigate the impact of mining on the bats. [7]
Bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight. Bat species account for about 20% of all mammals.

Male offspring tend to live in their natal groups until they are about two years old, sometimes being forcibly expelled by the resident adult males. [25] Vampire bats on average live about nine years when they are in their natural environment in the wild. [27] Vampire bats form strong bonds with other members of the colony.
Some bats lead solitary lives, while others live in colonies of more than a million. [215] For instance, the Mexican free-tailed bat fly for more than one thousand miles to the 100-foot (30 m) wide cave known as Bracken Cave every March to October which plays home to an astonishing twenty million of the species, [ 216 ] whereas a mouse-eared ...
The Bat Conservation Trust (BCT) is a registered British charity dedicated to the conservation of bats and their habitats in the UK. BCT was founded in 1991 and is the only national organisation solely devoted to bats. [1] Its vision is a world where bats and people live in harmony.

Wing membranes and ears are light grey-brown. The greater horseshoe bat weighs up to 30 grams (1.1 oz) [9] and can live up to 30 ...
Though numbers are large compared to other bats classified as endangered, this species is listed as such due to a >50% decline over the past decade. [31] Straw-coloured fruit bat: Eidolon helvum: 1.14 billion [32] = NT [33] Pallas's long-tongued bat: Glossophaga soricina: 1.03 billion [34] = LC [35] Angolan rousette: Lissonycteris angolensis ...
Both lists were reviewed in 2007, and the total number of UK BAP habitats increased from 45 to 65, and the number of UK BAP species increased from under 600 to 1,150. [ 4 ] From these, the formal list just for England (and laid out below) finally contained 56 of those 65 habitats, and 943 of the original 1,150 UK species.
