Chickadees remain here all year long, including during the coldest of all winters. They are cute, little birds who are very curious about humans, but what is most interesting about them is that they have such an amazing ability to stay warm in below zero weather. They have to eat constantly during the day in order to restore the fat that they lose when trying to remain warm. They fluff up their feathers and roost together at night in order to fight off the cold, and they are able to conserve energy by lowering their temperatures at night. So, next time you see a chickadee at your feeder, remember to appreciate how hard they are working just to survive.
