Dark-eyed Junco (Slate-colored or Oregon variants)

This is a distinctive outer tail feather from a Dark-eyed Junco. This small, 'snowbird' is characterized by its crisp plumage—often slate-grey above and white below—and its tendency to forage on the ground in flocks. The white outer tail feathers are a primary field mark, flashing brightly when the bird takes flight.

Striking bicolor pattern: the distal (tip) half is predominantly white, while the proximal (base) half is a dark slate-grey to charcoal. The transition between colors is a sharp, slightly diagonal line.

Tightly interlocked pennaceous barbs along the majority of the vane, transitioning to a small plumulaceous (downy) section at the base of the calamus.

Smooth, lightweight, and semi-flexible. The surface is matte with a slightly silky feel, characteristic of forest-dwelling passerines.

Sharp contrast between the white tip and dark base; narrow shape typical of a sparrow's tail; small size (under 3 inches).

Coniferous or mixed coniferous-deciduous forests for breeding; open woodlands, fields, parks, and suburban gardens during winter.

Widespread across North America. Breeds in the far north and high mountains; winters throughout the lower 48 United States and northern Mexico.

Primarily a granivore (seed-eater) in winter, helping with weed seed control, and an insectivore during the breeding season. They serve as a vital prey base for small hawks like Sharp-shinned Hawks.

Vesper Sparrow (larger, more streaked, less sharp color transition) and Black-throated Sparrow (different geographic range and marking pattern).

Dark-eyed Juncos are often called 'Snowbirds' because they suddenly appear in southern gardens as the first winter snows arrive. They are one of the most genetically diverse bird species in North America, with several distinct regional forms.

Good condition. The barbs are mostly intact with minor separation near the base. The lack of heavy wear suggests a relatively fresh molt or a bird in a sheltered habitat.
