Calculated to be the second most common land bird in North America, during the winter the Dark-eyed Junco is readily seen. It usually travels in small flocks and associates with other species of small birds. It is also a frequent visitor to seed feeders. During the summer pairs occupy territories in open coniferous and deciduous forest. Its nest is in a protected depression on the forest floor and lined with grass, moss and twigs. The young are fed insects. Several distinctive color forms nest in different parts of North America, but in the winter, junco flocks can often have representatives of several geographic forms together.
The four-digit banding code is DEJU.
