In the Hiraethog area, the Clocaenog Forest is one of the few places to see a red squirrel in the UK. Red squirrels are very elusive and spend much of their time in the trees. They build large nests (dreys), often in the forks of tree trunks and can range over wide areas, especially when looking for mates. In an effort to increase the declining numbers of the red squirrel in the UK, the Forestry Commission has been working hard to make the Clocaenog Forest even more attractive for them to live and breed, with great success.
Smaller than their grey cousins, the red squirrel has russet red fur and ear tufts, eating seeds, pine cones, fungi, shoots and fruits of shrubs and trees, and sometimes birds' eggs. They can choose between good and bad nuts by holding them in their paws! They do not hibernate, but instead store funghi in trees to eat over the winter months.
