Brown Long-eared Bat

Scientific Name: 

Plecotus auritus


The second most common bat in Britain with ears that are three quarters the length of its head and body. While at rest it tends to either curl its ears back or tuck them under its wings, so that only the inner ear lobe is visible. This is a medium sized bat with brown/grey long fluffy fur. The belly is a light grey and the face has a pink tinge to it. Both the wing membranes and ears are a light grey/brown. Juveniles are a pale grey without any brown tinges.


5 - 12g


The maximum recorded age is 30 years.


Widespread across mainland Britain with the exception of North and North West Scotland.


Plecotus auritus has a wide ranging habitat including both coniferous and deciduous woodlands, as well as orchards and parkland.


They mate during the autumn period and give birth to one young during June, which is weaned and ready to fly by the end of July.


Vulnerable to nocturnal mammals, especially cats due to their slow flight style and the fact that they will fly close to the ground while hunting and occasional land in order to capture their prey.


Plecotus auritus is not considered to be threatened. Fully protected under Schedule 5 of the Wildlife and Countryside Act (1981) as amended, and by the Conservation (Natural Habitats &c.) Regulations (1994). An agreement on the Conservation of Bats in Europe (EUROBATS) under the auspices of the Bonn Convention, also known as the Convention on Migratory species (CMS) is in force, and all European bats are listed under Appendix II of the CMS.
