When to see
April to OctoberAbout
Dormice are barely ever seen due to the fact they spend most of the day asleep! At night they come alive, climbing high into the trees on the hunt for a tasty snack. Their favourite foods are hazelnuts, berries and insects. Dormice build nests out of grass and leaves ready for the female to give birth to up to seven young. In autumn, dormice start looking for the perfect spot to hibernate for winter. They often choose to sleep in logs or leaves at the base of trees or just beneath the ground where they can avoid the winter cold.How to identify
The hazel dormouse has gingery-brown fur, large black eyes and a long, fluffy tail; it is much smaller than a squirrel.In our area
