Dark-eyed Junco (Slate-colored form)

The Dark-eyed Junco is a small, neat sparrow often nicknamed the 'snowbird' for its arrival with winter weather. Adults have a hood-like slate-gray head and breast, a white belly, and pinkish bills. Their most famous field mark is the flashing white outer tail feathers prominently displayed during flight.

Distinctive two-tone pattern featuring a dark charcoal gray or slate tip on the outer web contrasting sharply with a bright white inner web and margin, typical of the classic slate-colored junco tail pattern.

Pennaceous structure near the dark tip and outer web, transitioning to somewhat looser barbs along the white inner web. Barbs are intact but show minor fraying.

Smooth, lightweight, and matte finish typical of a small perching bird's flight or tail feather.

Sharp contrast between dark slate-gray and stark white on the outer tail feathers, characteristic of the slate-eyed form of Junco hyemalis.

Coniferous and mixed forests, woodland edges, brushy areas, and suburban yards during migration and winter.

Breeds across northern and montane North America; winters throughout most of the United States and northern Mexico.

Acts as an important seed predator and ground-forager, helping control weed seeds while serving as a key prey base for small hawks and northern shrikes.

Other sparrow species with white tail markings, such as Vesper Sparrows or Towhees, though the extensive clean white paired with dark slate-gray is uniquely striking in Juncos.

Juncos are ground-foraging birds that often hop rather than walk. Studies show that urban juncos have evolved slightly different wing shapes and lower stress hormones compared to their mountain counterparts.

Fair condition with slight fraying along the edges of the vane and minor wear at the tip, indicating it was naturally molted.
