Steller's Jay (often called Mountain Jay or Pine Jay)

This is a signature tail feather from the Steller's Jay, a striking crested bird of the West. Adult birds feature a charcoal-black head and crest that fades into a deep blue body. They are roughly 12-13 inches long with a 17-19 inch wingspan. They are bold, intelligent, and vocal inhabitants of the forest.

Brilliant cerulean to deep cobalt blue. The upper third of the feather shows characteristic fine black horizontal barring (narrow bands), which is a diagnostic trait for many North American jays. The underside is much duller and more grey-toned.

Pennaceous and interlocked for the majority of the vane; plumulaceous (downy) at the very base. The barbs show significant separation (fraying) due to environmental wear or molt stress.

The rachis is dark brown to black, stiff, and tapers towards the tip. Barbs are densely packed, emerging at an acute angle, providing the necessary surface area for flight stability.

Relatively stiff and smooth where intact, but currently appears matte and slightly ragged due to wear. The blue is a structural color (Schizochroism), meaning it relies on light refraction rather than pigment alone.

Tail (Rectrix). The length, relative straightness of the rachis, and the distribution of the blue structural color across both vanes are diagnostic of tail feathers in this genus.

Electric blue coloration combined with distinct black horizontal barring on the outer vanes, and a dark, rigid rachis.

Coniferous and mixed forests, particularly high-elevation pine and Douglas-fir forests, as well as residential gardens in wooded areas.

Western North America, ranging from southern Alaska through the Rocky Mountains and Pacific Coast down into the mountains of Central America.

Omnivorous foragers that act as important seed dispersers (especially for pine nuts and acorns) and opportunistic predators of insects.

Blue Jay (Cyanocitta cristata) features white tips and bolder bars; California Scrub-Jay (Aphelocoma californica) lacks the dark barring on the blue tail feathers.

Steller's Jays are excellent mimics; they can perfectly imitate the scream of a Red-tailed Hawk to frighten other birds away from bird feeders or food sources.

Jays figure prominently in Indigenous Pacific Northwest folklore as tricksters or messengers. While historically used in some decorative crafts, modern use is strictly regulated.

Look for these in late summer (post-breeding molt) in pine-oak woodlands. They are often found on forest floors or near campsites where these birds scavenge.

Fair condition. The feather shows 'ragging' at the edges and tip, likely an old feather naturally molted at the end of the breeding season. No obvious parasite damage is visible.
