UK mammals: identification guide

Garden and countryside mammals you are most likely to meet — from foxes and hedgehogs to badgers and deer.

Start with size and time of day: grey squirrels and rabbits by day; foxes, hedgehogs, and badgers mainly at night. Foxes have a bushy white-tipped tail; badgers have black-and-white face stripes; hedgehogs are spiny and roll into a ball.

How to identify common UK mammals

  1. 1

    Note size and shape. Compare to a cat or rabbit. Hedgehogs are low and rounded; foxes are dog-sized with a bushy tail; badgers are stocky with a broad head.

  2. 2

    Check the time. Hedgehogs, foxes, and badgers are mostly nocturnal. Grey squirrels and rabbits are active by day.

  3. 3

    Look at the face and tail. Foxes have a pointed muzzle and white-tipped tail; badgers have black-and-white facial stripes; squirrels have a long bushy tail.

  4. 4

    Use habitat clues. Rabbits prefer short grass and burrows; deer appear at woodland edges; otters need rivers or coasts.

  5. 5

    Photograph and compare. A clear side-on photo from a safe distance is enough to confirm most garden species.

Frequently asked questions

What mammal am I most likely to see in a UK garden at night?

Foxes and hedgehogs are the classic nocturnal garden visitors. Badgers visit quieter gardens near setts. Use a red-filtered torch to reduce disturbance.

How do I tell a fox from a dog?

Foxes have a narrower muzzle, taller pointed ears, and a long bushy tail often with a white tip. Their gait is lighter and more trotting than most pet dogs.

Are UK hedgehogs protected?

Hedgehogs are protected from certain forms of harm and are a priority conservation species in the UK. Never use slug pellets that harm them; leave gaps in fences and provide water.

Is there a dangerous wild mammal in the UK?

No native UK mammal poses a serious threat to people in normal encounters. Give badgers, deer, and foxes space; never handle wildlife with bare hands.
