The Juncos, genus Junco, comprise three to twelve species of small American sparrow.
- Dark-eyed Junco (Junco hyemalis). North America, in Canada and much of the United States. Six major subspecies groups (formerly called races) are sometimes treated as separate species. Their breeding ranges are described below.
- Slate-colored Junco (J. h. hyemalis). North American taiga forests from Alaska to Newfoundland and south to the Appalachian Mountains, wintering across the Lower 48 states.
- White-winged Junco (J. h. aikeni). In the Black Hills of South Dakota and Wyoming, United States.
- Oregon Junco (J. h. oreganus). The Pacific coast mountains from southeastern Alaska to California.
- Pink-sided Junco (J. h. mearnsi). Northern Rocky Mountains from southern Alberta to Idaho and Wyoming.
- Gray-headed Junco (J. h. caniceps). Southern Rocky Mountains from Colorado through Nevada to northern New Mexico.
- Red-backed Junco (J. h. dorsalis). Mountains of central Arizona and southern New Mexico.
- Guadalupe Junco (Junco insularis, often treated as a race of J. hyemalis). Guadalupe Island off the west coast of Baja California, Mexico; now rare and endangered.
- Yellow-eyed Junco (Junco phaeonotus). High mountains of Mexico, Guatemala, southeastern Arizona and southwestern New Mexico. Four major races or groups of races:
- Mexican Junco (Junco phaeonotus phaeonotus). High mountains of Mexico, southeastern Arizona and southwestern New Mexico.
- Chiapas Junco (Junco phaeonotus fulvescens). High mountains of Chiapas (southeast Mexico).
- Guatemala Junco (Junco phaeonotus alticola). High mountains of eastern Chiapas (southeast Mexico) and Guatemala.
- Baird's Junco (Junco p. bairdi). High mountains of Baja California Sur
- Volcano Junco (Junco vulcani). High mountains of Costa Rica and Panama.
Their breeding habitat is coniferous or mixed forest areas throughout North America, ranging from subarctic taiga to high altitude mountain forests in Mexico and Central America. They usually nest in a well-hidden location on the ground or low in a shrub or tree. Northern birds migrate farther south; southern populations are permanent residents or altitudinal migrants, moving only a short distance downslope to avoid severe winter weather in the mountains.
These birds forage on the ground. In winter, they often forage in flocks. They mainly eat insects and seeds.
"Junco" is the Spanish word for rush (the plant), though these birds are seldom found in rushes.
