Data Sheet

IUCN Conservation Status: Near Threatened, Vulnerable 

United States Conservation Status: n/a 

Diet: Insectivore 

With its broad wings, Bechstein’s bat will forage in forests or along forest edges for Lepidoptera, Diptera, Planipennia, and also non-flying insects. 

Fun Fact: As a tree roosting bat it is difficult for the whole population to fit in a single roost. Bechstein’s bat demonstrate a ‘fission-fusion’ behaviour where individuals will move between different trees to maintain community bonds with every indiviual within that colony.  

Appearance: An average-sized bat with a body mass between 7-14g. It has relatively long and shaggy brown or reddish fur which is paler in young individuals. It has a long-slim muzzle with long and separated ears.  

Habitat: This species is typically found in old growth and mature temperate forests and woodlands. It primarily relies on tree holes for roosts (natural features, woodpecker holes etc), but will use bat boxes and occassionally buildings.  

Conservation Concerns: Globally, this species is currently listed as ‘Near Threatened’ on the IUCN Red List but within Europe is listed as ‘Vulnerable’ due to loss of mature trees that can support the features that this species relies on for roosts.
