摘要

As the weather grows colder and snow begins to fall, black-capped chickadees remain active symbols of nature, even on the coldest winter days. Common year-round residents in New York state, chickadees survive the winter by roosting in dense vegetation and tree cavities. On cold winter nights, these small birds sometimes enter a state of regulated hypothermia, dropping their body temperature 18 - 22° F below normal daytime temperature. By doing so, they conserve a great deal of energy.
