Steller's jay
Cyanocitta stelleri
Bird
The crested blue jay of western conifer and conifer-oak forest, and the western counterpart to the blue jay of the east. It caches acorns and conifer seed in the ground and in bark and does not recover all of it, so the uncollected caches plant trees; the same bird is an accomplished mimic and a confident scavenger wherever people leave food.
Plan for this species
Location-fit plant set for Chicago, IL: host and specialist plants first, then nectar, fruit, seed, foliage, and shelter plants that still fit the current and mid-century climate read.

Oregon white oak
Supporting / Fruit plants
Takes acorns and buries them singly in the ground. The ones it does not come back for germinate, which makes the jay a dispersal route for the oak and not only a consumer of its crop.
Rocky Mountain juniper
Supporting / Fruit plants
Steller's jay overlaps this tree through western conifer and conifer-oak country and takes juniper cones along with the acorns and pine seed it caches. Recorded as plausible rather than documented, because the Wildflower Center bird list names waxwing, mockingbird and grosbeak specifically and then covers everything else with the phrase plus other species.
Ponderosa pine
Supporting / Seed plants
Caches pine seed in the ground and in bark. The caches it does not come back for are how a jay ends up planting the trees it feeds in.

Named by the Lady Bird Johnson Wildflower Center among the birds this oak draws. It eats the acorns and buries them singly in the ground, so the caches it abandons plant the next generation of oaks.

Range
Resident in conifer and mixed conifer-oak forest from southern Alaska down the Pacific coast and through the interior mountains of western North America to Mexico and Central America. Head colour varies geographically: coastal birds are blackish-brown headed, interior birds bluer with white streaks above the eye.
