Good to know

Six things about bats

Sound

Seeing with sound

Bats send out high-pitched calls and listen for the echoes to find their way and catch insects in the dark.

Appetite

Midge munchers

A single pipistrelle can eat thousands of tiny insects in one night.

Weight

Tiny

A pipistrelle weighs about the same as a 20p coin.

Flying

Real flyers

Bats are the only mammals that can truly fly. Their wings are stretched skin between long finger bones.

Winter

Winter sleep

In winter bats hibernate in cool, quiet places like old buildings, caves and tree holes.

Law

Protected

All bats in Britain are protected by law, and so are the places where they roost.

Out and about

How to spot them

Stand near trees, a pond or a street light about twenty minutes after sunset on a warm, still evening and watch the sky against the last light.

Lend a hand

How to help

Grow night-scented flowers and keep a pond: both bring the insects bats eat. Put up a bat box and keep outside lights off where you can.
