Likely Common Pheasant (Ring-necked Pheasant); identification is tentative from one feather.

A long, dark flight feather with a pale shaft and damaged-looking basal barbs. Common Pheasants are large, long-tailed ground birds; males are brightly patterned, while females are mottled brown and cryptic.

Mostly dark brown to black, with a narrow pale edge and subtle pale markings near the base. The visible side does not show enough diagnostic pattern to confirm species or sex.

Pennaceous over the dark vane, with extensive loose, separated barbs along the lower portion; no clear aftershaft is visible.

Long, pale rachis, slightly curved, with dark barbs becoming sparse and ragged toward the base; upper vane is denser.

Upper vane appears smooth and matte, while the basal barbs are loose, frayed, and soft-looking.

Probably wing; asymmetry and tapered outline fit a primary flight feather, though wear or damage obscures its original shape.

Approximately 30 cm long, dark pointed vane, pale rachis, and marked asymmetry. These traits indicate a large bird but are not species-diagnostic.

Pheasants use woodland edges, scrub, farmland, and grassland; they forage on the ground and roost in cover or trees.

Native to Asia and widely introduced across Europe, including Poland; generally resident, with local movements.

Pheasants are ground-foraging omnivores and prey for foxes and raptors; European populations are abundant, often supported by releases. Collection rules may protect wild birds and their feathers.

Large dark feathers of buzzards, eagles, and ravens can resemble this. Raptor feathers often have more distinctive barring, while pheasant feathers may show patterned or mottled areas; this specimen is insufficient for a firm distinction.

Common Pheasants were introduced widely for game hunting and are now familiar across much of Europe.

Pheasant feathers have been used in fly-tying, decoration, and traditional crafts; laws governing collection and possession vary, so check local regulations.

Compare with a reference collection and record exact length, vane width, and pattern on both sides. Near Tułowice, pheasant and forest raptor feathers are both plausible.

Basal barbs appear heavily separated or damaged; tip and upper vane look reasonably intact. Condition: fair; no obvious fault bars or contamination.
