During most of the year, Chickadees eat insects, hanging upside down on a branch to scavenge he lower sides of twigs and leaves. In the winter, insects are not to be found, so these small birds have learned to adjust their menus, and you can help. If you have bird feeders, be sure to keep them filled with sunflower seeds. Many wintering birds need the oil in these seeds to keep their metabolism going. If you hang a cake of suet, they love the fat there too. A well-fed chickadee will shiver all night long, even when fast asleep, just to keep warm. When the weather is really cold, some of the little birds have to go into a state of torpor to make it through the night. Their body temperature can drop from the daytime high of 108 degrees Fahrenheit to a low of 50 degrees Fahrenheit. It takes a lot less energy to keep a chickadee's body at 50 degrees than at 108 degrees.
If your body went that cold for a night it would probably never get warm again. The same can happen to chickadees; over 70 percent do not survive their first year. Some chickadees live for 12 years, but most die before they are two and a half. The chickadee's winter world is a harsh thankless place, and the death of another larger animal can help keep a flock of chickadees alive through the cold winter by scavenging.
