Photo Share: Cardinal in snow

Birds are warm-blooded. In general, this means that they maintain their body temperature within a certain range even when the temperature around them changes. The maintenance of body temperature within a normal range depends on the amount of heat the bird produces.

On cold, wintry days, most birds fluff up their feathers, creating air pockets, which help keep the birds warm. The more air spaces, the better the insulation. Some birds perch on one leg, drawing the other leg to the breast for warmth.

To keep up their high metabolic rate, most backyard birds eat rich, energy foods such as seeds, insects and suet. There are some times, however, when birds are not prepared to deal with sudden drops in temperature or sudden winter storms. At times like these, it is especially helpful to have feeders full so that birds can find food easily.
