Dark-eyed Junco (Slate-colored form)

The Dark-eyed Junco is one of the most familiar and abundant forest sparrows of North America. Often called 'snowbirds' for their arrival in lower latitudes as winter sets in, they are neat, sparrow-sized birds with distinctive pink bills, dark hoods, and flashing white outer tail feathers that are especially conspicuous when they flush from the ground.

Stark contrast of dark slate-gray to blackish-charcoal on the inner web and proximal areas, transitioning sharply to brilliant white on the outer webs and distal portions of the outermost tail feathers.

Pennaceous vane along the upper portion with tightly interlocked barbs and barbicels, transitioning to slightly looser structure near the base.

Smooth, silky, and matte texture with rigid enough vanes to maintain aerodynamic stability during flight.

The striking, sharp bicolor pattern of dark gray and brilliant white on the outer tail feathers is the definitive diagnostic feature for the slate-eyed form of this species.

Coniferous and mixed forests, woodland edges, brushy areas, mountain thickets, and suburban yards, especially during winter months.

Breeds across northern North America and mountainous regions down to Mexico; winters throughout most of the United States and lower Canada.

Juncos play a vital role in controlling weed seed populations in forest and suburban ecosystems while serving as a primary prey base for various small raptors and shrikes.

Other sparrow species with white in the tail, such as the Vesper Sparrow, but the Junco's distinct dark hood and starkly contrasting tail pattern are usually unmistakable.

Juncos are ground-foraging birds that hop rather than walk, frequently scratching at leaf litter to uncover seeds. They form large flocks in winter and establish dominance hierarchies based heavily on the amount of white in their tails.

The feathers appear clean, fresh, and well-maintained with intact barbs and no signs of severe wear, fading, or parasitic damage.
