Brown Long-eared Bat

Wingspan: 23-28cm Weight: 6-12g Lifespan: typically 5 years

(Plecotus auritus)


Identification: A medium-sized bat with long grey brown fur with white fur underneath. They have incredibly large ears to hear their very quiet echo location calls. The ears are tucked under the wings when at rest. General: A native species which likes to forage in woodland, hedgerows and farmland usually following linear routes. They are slow flyers but are very agile and can even hover. They can catch prey on the wing or glean from foliage and they often roost to eat large prey. Mating takes place in the autumn and a single pup is born in late spring in small communal maternal roosts that frequently contain males. Pups are weaned after 6 weeks. Roosts are typically in trees and buildings. Unlike most other bat species which are found in hibernaculum in the warmest available temperature, this species choose to hibernate in areas with the lowest available temperature in tunnels and caves. They can withstand temperatures around freezing. Distribution - UK: There are approx. 250,000 distributed widely throughout the UK apart from the far north-east of Scotland and some Scottish islands. The population is stable. Sonogram GW / AL
