Background

One of the largest British bats, the Noctule Bat has a golden-brown fur. The wings, ears and face of these species are darker making it one of the easiest bat species to identify within the UK.

Habitat

Like a number of bat species the Noctule Bat resides in wooded areas. They live in holes within trees, created either by rot or woodpeckers. These bats can be commonly found across England, Wales and southern Scotland.

Diet

The dietary intake of the Noctule Bat is insect based, feeding on mayflies, beetles and moths.

Predators & Threats

Main threats and limitations are from agricultural activities. Areas with intensive agricultural activity reduce the area and food resources available to the bats, leading to a decline in local populations. Predators include snakes, hawks and owls. Weasels and raccoons also prey on bats by climbing into roosts.
