About the species
The warm pink-brown body contrasts with a pale crown streaked in black. On the upper wing, a vivid blue panel crossed by fine black bars appears among the darker feathers. A white rump above the black tail adds another clear contrast when it turns.
Its warning call is a rough, rasping screech, especially when it spots a predator. It can also mimic other species, including a buzzard’s mew and a goshawk’s cackle, making its voice hard to place by sound alone. In autumn it buries acorns for winter, and the ones it does not recover help oaks spread.
Mixed woodland, especially places with oaks, is its usual habitat, though it has also started turning up in urban areas. It forages in trees and on the ground, taking insects, seeds, berries and other available food.
Did you know?
-
Good memory for stashed
The jay hauls acorns from oak woods into neighbouring pine stands and tucks them under thick moss or fallen needles, fixing the exact spot of each cache in memory at once.

Plants oaks without meaning to
The acorns the jay forgets sprout as young oaks the next spring — without meaning to, the bird plants oaks far from the parent trees, helping the forest spread.

Caring partner
A male Eurasian Jay watches which grubs his mate has been eating, then brings her exactly the ones she hasn't tried — reading her shifting tastes.

Where to find
-
In wooded parts of a city, listen for the Eurasian Jay's harsh, rasping call when it spots a predator.
-
Under oaks in autumn, watch for acorns being buried in the ground — caching is most intense then.
-
During breeding, a nest is very occasionally placed on a building; watch nearby for adults carrying food to the young.
