The Juncos, genus Junco, comprise three to eight species of small American sparrow.

• Dark-eyed Junco (Junco hyemalis). North America, in Canada and much of the United States. Five major races or groups of races, sometimes treated as species:
  • Slate-colored Junco (J. hyemalis hyemalis). North America in taiga forests from Alaska to Newfoundland and south to the Appalachian Mountains, wintering further south.
  • White-winged Junco (J. hyemalis aikeni). In the Black Hills of South Dakota and Wyoming, United States.
  • Oregon Junco (J. hyemalis oreganus). The Pacific coast mountains from southeastern Alaska to California.
  • Pink-sided Junco (J. hyemalis mearnsi). Northern Rocky Mountains from southern Alberta to Idaho and Wyoming.
  • Gray-headed Junco (J. hyemalis caniceps). Southern Rocky Mountains from Colorado to central Arizona.
• Guadalupe Junco (Junco insularis, often treated as a race of J. hyemalis). Guadalupe Island off the west coast of Baja California, Mexico.
• Yellow-eyed Junco (Junco phaeonotus). High mountains of Mexico, Guatemala, southeastern Arizona and southwestern New Mexico. Three major races or groups of races:
  • Yellow-eyed Junco (Junco phaeonotus phaeonotus). High mountains of Mexico, southeastern Arizona and southwestern New Mexico.
  • Guatemala Junco (Junco phaeonotus alticola). High mountains of Chiapas (southeast Mexico) and Guatemala.
  • Baird's Junco (Junco phaeonotus 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.
