During the summer American tree sparrows (Passeriformes: Emberizidae: Spizella arborea) breed in northern Canada and Alaska. In the winter, however, they migrate southward across much of the United States. The other day I noticed several gathered around a friend’s bird feeder, foraging along the snowy ground for the spilled seed. Eating is a full-time job for these birds since they must consume the equivalent of about 30% of their body weight every day. Despite being labelled “tree” sparrows they feed, breed, and nest predominantly on the ground.
