How birds survive cold, windy winter nights

During these windy, cold nights you might wonder where the birds that don’t migrate south for the winter sleep. Birds that nest in cavities like chickadees, woodpeckers, wrens, and nuthatches tend to sleep in tree hollows, man-made nest boxes or roosting pockets far away from many predators. Other birds like cardinals, jays, doves, juncos and finches roost in dense brush or foliage. I have a lot of backyard birds that like to sleep in the pine trees near the feeding stations. If the wind is blowing, they go to the other side of the tree and avoid it.

Most birds will fluff up their feathers to cover their feet and create air pockets that will help them keep warm like a down jacket. Birds that perch also scrunch down to sleep because that automatically makes the toes grip their perch and stay locked. In the legs of most tree-dwelling birds, tendons extend down the leg behind the ankle to attach to the tips of the toes and when their knees bend, the tendons are pulled taut, making the toes on their feet clench. Even on windy nights, this grasp cannot be released until they wake up and their limbs are straightened again.

Another way birds combat the cold is by shivering. This converts muscular energy into heat for the short term, but the energy must be replenished shortly thereafter. By keeping your feeders filled with high energy, high fat foods you can provide your birds with the vital nutrition they need to survive. High on the list of best choices to meet this nutritional need is suet or seed blocks and certain seeds like peanuts, sunflower  and nyjer seed.
