Colour & Pattern
Vibrant cobalt to deep blue coloration featuring striking horizontal black bars (barring), created by structural light scattering without true blue pigments

Tightly interlocked pennaceous structure with firm barbs and barbules, well-formed and intact
Texture & Surface
Smooth, firm, and slightly glossy vane with good structural rigidity
Key Features
Rich deep blue color combined with distinct, clean black horizontal bars across the vane
Habitat
Coniferous and mixed mountain forests, heavily wooded residential areas, and foothills
Geographic Range
Western North America, ranging from Alaska down through the Rocky Mountains, Pacific Coast, and into Central America
Ecological Role
Acts as an important seed disperser and forest sentinel, alerting other wildlife to predators with its harsh alarm calls
Similar Species
Blue Jay (Cyanocitta cristata), which features lighter blue feathers with white tipping and blue-and-black checkered patterns rather than solid dark crests
Interesting Facts
Like other jays, Steller's Jays are crucial for forest regeneration because they cache and forget thousands of acorns and seeds each year
