How to identify UK animals

Burrowing mammal homes Can you tell who lives in a hole like this?

Have you ever come across a hole in the ground or bank and wondered which animal lives in it? Or seen signs of digging and questioned which animal has been hard at work excavating a new home?

Burrows can provide valuable protection from predators and the weather and provide a safe place to raise young. They can range from a small and simple hole in the ground to a sprawling series of complex chambers and interconnected tunnels with multiple entrances.

Below are some common animal burrows, see if you can recognise the burrow and then match it up with the occupier.

Of course things are not always as straight forward as they may appear at first sight. For example a foxes den could originally have been made by a badger and it's not unusual for foxes and rabbits to share a badgers set! Stoats and weasels may also use holes vacated by their prey.

When to see

Winter is a great time to spot mammal holes and burrows as the surrounding vegetation has died back, while droppings (scat) and footprints in mud and snow can also provide tell-tale signs. We have downloadable (PDF) field guides to animal homes and animal droppings for a further helping hand.

If you have a camera or phone with you, then these handy tips and tricks will help you to get the best out of your photographic equipment, whatever your level of expertise.

Please do not disturb wild animals in their burrows and remember to follow the Countryside Code when out and about.
