Brandt’s Bat, Myitus brandtii

The Brandt’s bat has a large population in northwest of England but is endangered in Austria.

The Brandt’s Bat has shaggy brown fur with a pale grey belly. This bat is not a large bat and weighs less than half an ounce and measures up to two inches long. Its wingspan is more than triple its body length at 7.5 to 9.5 inches.

Brandt’s bat eats only insects (insectivorous) and is not blind. However, echolocation is used for “night-vision,” so that while hunting at night it does not run into trees or lose its way back to its dwelling. Moths, small insects, and spiders that can be found on water surfaces or woodlands are the main menu selections.

Dwellings are usually woodlands near water; during summer months they can be found in roof timbers and in bat boxes. Hibernation is suspected to be in caves, cellars, mines and tunnels.

Autumn is when mating normally occurs but fertilization is delayed until spring. This allows mothers to hibernate to store up energy and also to colonize for birthing purposes. The maternity colonies will begin forming in the summer and contain between 20 and 60 females. The pup can fly at 3 weeks and then can hunt independently at 6 weeks.
