Three blue tits sitting on one of our bird feeder today. -20 degrees Celsius.
Please remember to feed our flying little friends if possible, if you live in a place where the winter is cold! It's very important, so that the birds will survive and stay in the area over the freezing time. They need a lot of energy to keep themselves warm. I've noticed that they like especially peanuts and sunflower seeds. The birds will answer by bringing joy and singing to you.
If you've already started feeding, it's most important to continue it throughout the winter! Otherwise the birds don't know where to find food anymore and they will die.
