Bechstein's bat


The relatively long and broad ears of the Bechstein's bat have a pointed ear cover, which is typical for all species of mouse ears (Myotis). They have a wingspan of between 25 and 29 cm and weigh between 7 and 14 g.


This forest-dwelling species prefers tree hollows as summer habitats. As a substitute, however, bird nesting boxes are also accepted time and again. However, bird nesting boxes are not a sufficient alternative, as the Bechstein's bat frequently changes its habitat and is therefore dependent on a habitat network, such as exists in a cave-rich forest with many old trees and a corresponding proportion of deadwood.

Like other bats, the Bechstein's bat feeds on small insects such as flies, midges and moths. Since this species has mastered shaking flight and can perceive the crawling sounds of its prey, it also picks up, for example, spiders and caterpillars directly from the vegetation. Its hunting grounds include the forest, especially the insect-rich forest layers close to the ground.
