Winter's little grey bundle of life and energy
One of the miracles of our world is the lowly chickadee. It’s a common little bird most often seen in winter. If there is a bird feeder nearby, you will see one or two of these little grey bundles of energy. The chickadee's range includes most of the United States.
A full-grown chickadee weighs little more than half an ounce, about the weight of a few pieces of paper. Inside that tiny feathered frame is a heart that beats close to 700 times a minute, so fast that through a stethoscope its sound is just a busy buzz. Its body temperature ranges around 105 degrees, which explains the frenzied beating of its heart. On cold winter nights, these birds reduce their body temperature by up to 10-12 °C to conserve energy.
The chickadee has a black cap and bib with white sides to the face. Its underparts are white with rusty brown on the flanks and its back is gray. It has a short dark bill, short wings and a long tail.
