Steller's Jay
Cyanocitta stelleri
The Steller's Jay is a striking corvid of western North America, easily identified by its prominent crest and bold blue and black plumage. These intelligent birds are often found in coniferous forests, but readily adapt to human-modified landscapes like parks and campgrounds. They are known for their inquisitive nature and diverse vocalizations.

01 / The telltale details
You’ll know it
when you see it.
Start with shape and behavior. Then look for the smaller details.
- 01
Crest
A prominent, shaggy crest on the head is a key feature, varying in color regionally.
- 02
Head and Body Color
Northern populations typically have a blackish-brown to black head and upper body, transitioning to deep blue on the wings, belly, rump, and tail.
- 03
Forehead Streaks
Small streaks on the forehead and around the eye can be white, especially in inland populations, or blue near the coast.
- 04
Overall Plumage
The body is a vibrant blue, contrasting with the darker head and crest.
02 / A place in the world
Where life
takes it.
Steller's Jays primarily inhabit coniferous and pine-oak forests, particularly in mountainous regions and along the northwest coast. They also frequent mixed oak and redwood groves, and can be found in well-wooded suburbs, orchards, parks, and campgrounds.
Stay a while. Or follow the season.
Steller's Jays are generally permanent residents throughout their range. However, some populations may move to lower elevations during winter, and irruptions into lowlands can occur when mountain food sources are scarce.
03 / Listen a little closer
A voice
of its own.
Their vocalizations are diverse, including harsh, scolding calls and shrill, hawk-like imitations. They are excellent mimics of other birds, animals, and even mechanical sounds.
04 / The life behind the feathers
A day in its world.
On the menu.
These omnivorous birds consume a wide variety of foods including insects, seeds, berries, nuts (especially acorns and pine nuts), small animals, eggs, and nestlings. They also readily consume human scraps and bird feeder offerings.
Steller's Jays forage both on the ground and within tree branches, often hopping with their long legs. They are known to cache surplus food and will also raid the caches of other jays. They can pound hard nuts with their bills to open them.
A place to begin.
Both sexes construct a bulky, cup-shaped nest of twigs, leaves, moss, and sticks, cemented with mud and lined with fine materials. Nests are typically placed in conifers, often high in the tree, but can also be found in shrubs, tree hollows, or even buildings.
The little routines.
Steller's Jays are social birds, often traveling in groups outside of the breeding season and sometimes joining mixed-species flocks. They are bold and inquisitive, frequently approaching humans. During nesting, they become secretive but are aggressive if their nest is threatened.
One more reason to pay attention
A familiar face.
A few surprises.
Steller's Jays were first recorded in Alaska in 1741 by naturalist Georg Steller, after whom the species is named.
Along with Blue Jays, Steller's Jays are the only New World jays that use mud in the construction of their nests.
The oldest recorded Steller's Jay lived to be at least 16 years and 1 month old.
05 / An eye for the difference
Could it be
someone else?
Blue Jay
Cyanocitta cristataSteller's Jays are generally darker overall, especially on the head and crest, and are found west of the Rocky Mountains, while Blue Jays are eastern.
California Scrub Jay
Aphelocoma californicaCalifornia Scrub-Jays lack a crest and have a plainer blue head without the dark hood of the Steller's Jay.
Clark's Nutcracker
Nucifraga columbianaClark's Nutcrackers are primarily gray with black and white wings, lacking the prominent crest and blue plumage of the Steller's Jay.
