They have been the subject of fear and superstition over the years, but bats are a valuable part of our ecosystem.
The only mammals capable of flights, bats are supreme hunters swooping and darting around the skies at dusk and in darkness in pursuit of insects.
Their prey includes many bugs considered pests, so it's never a bad thing to have a few bats in your garden.
Here are all the species that call Scotland home.
5. Common Noctule Bat
Largely restricted to southern areas of Scotland, the Common Noctule is our fastest bat - reaching speeds of around 30mph. It's also the largest of the native bat breeds, weighing up to 40g. You can identify it by its small, rounded brown ears, or simply by the racket it makes - they are as loud as they are fast and large. | Canva/Getty Images
6. Lesser Noctule Bat
Also known as Leisler's Bat or the Irish Bat, the Lesser Noctule Bat can most commonly be seen hunting around rivers and streams close to woodland in the south west of Scotland. It can be distiguished from the Common Noctule by its darker fur. | Canva/Getty Images
7. Natterer's bat
Easy to identify by its hairless pink face - as well as its long, thin ears - the Natterer's Bat can be found in central and Scotland, where it frequents large parks and woodlands. | Canva/Getty Images
8. Whiskered Bat
Count yourself lucky if you see a Whiskered Bat in Scotland - they are our rarest species. Only found in the south of the country, they feed in woodland clearings and around rivers. They can be identified by their golden-tipped fur and grey belly. | Canva/Getty Images
