Britain's 'vole patrol' launched

Water vole
Animal lovers are being asked to look out for Britain's most endangered mammal, the water vole.

British Waterways, in charge of the UK's canals and rivers, is launching a survey of water voles and other wildlife on its property.

The animal is in danger because its habitat is vanishing, and it's being threatened by American mink, which have recently arrived in Britain.

The group says knowing where voles live is vital if we are to protect them.

Vole spotting

But if you do go vole-spotting, you should be careful that you don't mix them up with brown rats.

Voles have small hidden ears, silky brown fur, a blunt nose and a short furry tail, whereas brown rats have big ears, grey-brown fur, a pointed nose and a long, pink, hairless tail.

Water voles also feed on vegetation while rats eat lots of different things.
