Birdfeeders

Birds have many physical characteristics that help to keep them warm in the cold winter months. Their feathers provide remarkable insulation and some species even grow extra feathers for extra winter protection. The oil that coats birds’ feathers provides insulation as well as waterproofing. All birds legs and feet are covered with scales that minimize heat loss. They can further reduce heat loss by constricting blood flow to their extremities. Many birds can gorge during the fall to build up fat reserves for the winter. Birds have also developed behaviors to help keep them warm. We have all watched birds sit and fluff out their feathers. This creates air pockets that add additional insulation from the cold. In addition, we see them standing on one leg or crouched low to cover both legs to shield them from the cold. So yes, birds have lots of ways to help protect themselves from the cold, but during frigid temperatures, many birds still succumb. During winters as bad as this one has been, bird mortality can be very high so we all must do what we can to help our backyard birds survive. The most important thing is to consistently offer high fat foods such as black oil sunflower seeds, suet, scraps and whatever other high fat foods you can offer to give birds plenty of energy to generate body heat. It is especially important to have all birdfeeders full consistently but especially early in the morning and just before dusk. Our hanging tube feeders are busiest at dawn when birds are in need of lots of food after a cold night. I can always tell when either a storm is coming or the night is going to especially cold, for the hanging tube feeders, platform feeders and suet feeders are especially busy starting in the early afternoon as the local birds are filling up before dark. In areas that are covered in snow, liquid water is especially important to help birds survive. Melting snow themselves uses up too much precious energy.
