Dark-eyed Junco

Junco hyemalis

Passerellidae

The 'snowbird.' Slate-gray above, white below, with a sharp bicolor line separating the two — like a dark-hooded monk in a white robe. The most commonly reported bird at feeders in North America during winter. Ground foragers that flush from lawn edges in small flocks, flashing white outer tail feathers.

Arrives from northern forests in October; departs in April.

Diet

What it eats.

Diet often shifts dramatically between breeding season and the rest of the year — especially for insectivorous birds that pivot to native berries in fall and winter.

Summer / breeding season

  • Breeds in northern forests — insects, caterpillars, spiders for nestlings

  • Not present in NJ during breeding season (except at high elevations in the Kittatinny Ridge)

Fall / winter

  • White millet and cracked corn scattered on the ground

  • Black-oil sunflower under feeders

  • Native grass and weed seeds

  • Seeds of goldenrod, aster, and other standing perennials
