Was so good to see this bird today. The frost was heavy, the skies were clear, and the temperature was 29F and the air still. Dark-eyed Juncos are neat, even flashy little sparrows that flit about forest floors of the western mountains and Canada, then flood the rest of North America for winter. They’re easy to recognize by their crisp (though extremely variable) markings and the bright white tail feathers they habitually flash in flight. One of the most abundant forest birds of North America, you’ll see juncos on woodland walks as well as in flocks at your feeders or on the ground beneath them. Taken with a Canon 7D and a Canon EF 300L f/2.8 IS Lens.

Cool Facts

  • Juncos are the “snowbirds” of the middle latitudes. Over most of the eastern United States, they appear as winter sets in and then retreat northward each spring. Some juncos in the Appalachian Mountains remain there all year round, breeding at the higher elevations. These residents have shorter wings than the migrants that join them each winter. Longer wings are better suited to flying long distances, a pattern commonly noted among other studies of migratory vs. resident species.
  • The Dark-eyed Junco is one of the most common birds in North America and can be found across the continent, from Alaska to Mexico, from California to New York. A recent estimate set the junco’s total population at approximately 630 million individuals.
  • The oldest recorded Dark-eyed Junco was 11 years 4 months old.
  • Dark-eyed Juncos breed in forests across much of North America and at elevations ranging from sea level to more than 11,000 feet. They are often found in coniferous forests incuding pine, Douglas-fir, spruce, and fir, but also in deciduous forests such as aspen, cottonwood, oak, maple, and hickory. During winter and on migration they use a wider variety of habitats including open woodlands, fields, roadsides, parks, and gardens.
  • Dark-eyed Juncos are primarily seed-eaters, with seeds of chickweed, buckwheat, lamb’s quarters, sorrel, and the like making up about 75% of their year-round diet. At feeders they seem to prefer millet over sunflower seeds. During the breeding season, Dark-eyed Juncos also eat insects including beetles, moths, butterflies, caterpillars, ants, wasps, and flies.
