While in their winter habitat, Chipping Sparrows are non-stop eating machines. Each one must consume over two pounds of seeds through the course of the winter to survive. With an average body weight of only 13 grams, this means that Chipping Sparrows consume over 70 times their own weight in seeds each winter.
Looking good! Most birds molt all of their body feathers once or twice a year, the Chipping Sparrow follows the same schedule except that it may also replace the feathers on its face and throat up to six times a year.
