There is soon cause to discuss the life of beavers – at the end of February their heat period starts.

When a beaver dives, a line of small air bubbles remains along its path. The fur of the animal is not wetted but for this it has to take care. Its fur consists of an extremely dense undercoat through which water cannot penetrate and rougher and longer upper hairs.

The air layer in the undercoat protects the beaver against wetting as well as cooling off.

The Nordic winter is a harsh challenge not only for birds but also for mammals. Some bats fly to spend winter in warmer parts of Europe, others stay to hibernate at home. Bears, badgers, raccoon dogs, dormice, birch mice and hedgehogs also hibernate. Many quadrupeds however remain to face  hunger and cold and so do not even shy off from the dangerous proximity of humans when  searching for food and shelter. Smaller mammals – for  instance some rodents - also visit the birdfeeders.

The season has arrived when the brown hares begin to take an interest in the fruit trees in gardens. The thaw created a new and load-bearing layer on the snow that is covered by a fresh snow layer – all traces of activities nicely visible.
