Description

The Steller's Jay is a bold and charismatic corvid known for its dark blackish-blue crest, rich blue body plumage, and raucous calls. It is the only crested blue jay found in western North America.

Colour & Pattern

Striking coloration featuring a deep, dark blue to blackish head and upper back transitioning into brilliant metallic azure and cobalt blue bars along the outer web

Barb Structure

Pennaceous vane on the distal portion with tightly interlocked barbicels, transitioning into a plumulaceous (fluffy) structure near the base

Rachis & Barb Pattern

Central rachis is sturdy, curved, dark at the base and lightening toward the tip, with densely packed barbs angled tightly toward the distal end

Texture & Surface

Smooth, firm, and glossy along the pennaceous vane with a rigid structural integrity for aerodynamics, softening to downy barbs at the base

Feather Placement

Wing, specifically an outer primary flight feather, determined by the stiff rachis, asymmetric shape, and distinctive coloration

Key Features

Deep cobalt blue barring and distinct deep blue-to-black color gradient characteristic of the Steller's Jay wing feathers

Habitat

Coniferous and mixed mountain forests, heavily wooded foothills, and canyons, often in pine-oak woodlands

Geographic Range

Western North America, extending from Alaska down through the Rocky Mountains, the Pacific Coast, and into Central America

Ecological Role

Acts as an important seed disperser, particularly for conifer seeds and acorns, playing a vital role in forest regeneration

Similar Species

Blue Jay (Cyanocitta cristata), which features bright sky-blue feathers with white spotting and black barring, lacking the deep dark blue and black crest tones of the Steller's Jay

Interesting Facts

Steller's Jays are intelligent problem solvers that readily mimic the calls of several raptor species, especially the Red-tailed Hawk, to deter competitors from food sources

Cultural Significance

Held in high regard in many Indigenous cultures of the Pacific Northwest as a trickster figure, a guardian, or a messenger spirit

Field Identification Tips

Look for molted feathers near forest floors, camp sites, or rocky outcrops in coniferous mountain regions where Steller's Jays congregate

Condition Notes

Good condition with minor wear at the tip and slightly frayed barbs near the base where it met the skin
