Dark-eyed Junco

The Dark-eyed Junco is a neat, medium-sized sparrow often referred to as a snowbird due to its arrival in winter. It has a rounded head, a stout pink bill, and a brisk, hopping ground-foraging habit. Adults typically display crisp grey, brown, or slate-colored upperparts contrasting with a white belly, accompanied by flashing white outer tail feathers visible in flight.

Striking bicolored pattern with deep dark charcoal-grey or blackish inner web and a sharply contrasting bright white outer web, characteristic of the species' signaling tail feathers

Pennaceous vane along the distal portion with tightly interlocked barbicels, transitioning to a slightly more plumulaceous structure near the base

Smooth, silky, and matte texture with high flexibility and standard passerine rigidity

Sharp contrast between the dark grey inner web and the brilliant white outer web, a definitive diagnostic trait for identifying outer tail feathers of this species

Coniferous and mixed forests, woodland edges, brushy areas, mountain slopes, and suburban gardens during migration and winter

Widespread across North America, breeding extensively in the boreal forests and high mountain ranges of Canada and the United States, wintering throughout most of the US and northern Mexico

Acts as an important ground-foraging seed consumer and insect predator, serving as a key prey base for small forest raptors and northern shrikes

Vesper Sparrow or other grassland sparrows, but distinguished by the extensive, clean white panel restricted to the outer edge of the tail feather

Juncos flash their white outer tail feathers when flushed to startle predators and signal alarm to flock members during flight

Good condition with minor wear at the extreme tip, barbs mostly intact and showing clear structural integrity
