What do Brandt’s bats look like?

One of the smaller bat species, Brandt’s bats measure around 4-5cm in length and weigh in at 4.5-9.5g. They have long, shaggy fur which is dark brown in colour, with a grey belly. They have a pink face, small nose and slim, pointed ears.

Not to be confused with: the whiskered bat. The two species were actually considered the same up until 1970 when they were separated. Brandt’s bats are very similar to the whiskered bat but are slightly larger in size.

What do Brandt’s bats eat?

The Brandt’s bat’s diet consists of moths, midges and spiders, which it catches on the wing when it heads out to hunt after sunset. They utilise their quick and skilful flight to take their prey, often picking it off foliage low to the ground, as well as foraging near water.
