Racial Composition of Wintering Flocks of the Dark-Eyed Junco, Junco hyemalis, in the Great Smoky Mountains National Park
Savage T. Racial Composition of Wintering Flocks of the Dark-Eyed Junco, Junco hyemalis, in the Great Smoky Mountains National Park. Pages 25. In Savage T (ed): Seventh Annual Scientific Research Meeting. Gatlinburg TN. June 25 - 26, 1981. National Park Service. Atlanta
Two forms of the species exist in the lower elevations in GRSM during the winter months -- a resident form of high elevations and a migrant form from northern latitudes. Pink bills and legs usually identify the northern migrants, while horn-colored bills and legs the locals, but these features are not always clear-cut, as gradations occur. Migrants dominate the flocks in early fall, but snows drive the locals down. Storms in the north increase the migrant cadre, local storms cause an increase in the local birds until in late March and early April when all the birds leave.
