The temperature overnight was colder than predicted so the birds have been busy coming to the feeders this morning to get some food to burn to stay warm. Feathers, specialized scales on legs and feet, and fat reserves help birds survive the cold temperatures. They will also fluff feathers to create air pockets, catch some sun on clear days, huddle together while roosting and even shiver to generate more body heat. But even with all these adaptations to stay warm, some birds will still succumb to frigid temperatures during severe winters.
