Eurasian jay

Garrulus glandarius

Also calledAbu zurayq (Arabic) · Alakarga (Turkish) · Eichelhäher (German) · Geai des chênes (French) · Arrendajo (Spanish) · Gaai (Dutch)

A colourful, shy woodland crow, pinkish-brown with a white rump and a dazzling blue-barred wing patch. Each autumn it buries thousands of acorns, and the ones it forgets grow into new oak woods.

The Eurasian jay is a species of passerine bird in the family Corvidae. It has pinkish brown plumage with a black stripe on each side of a whitish throat, a bright blue panel on the upper wing and a black tail. The Eurasian jay is a woodland bird that occurs over a vast region from western Europe and north-west Africa to the Indian subcontinent and farther to the eastern seaboard of Asia and down into south-east Asia.

What it can do

  1. iA single jay may cache several thousand acorns in an autumn
  2. iiRemembers cache locations months later, even under snow
  3. iiiIts forgotten caches are a major means by which oaks spread uphill and into open land
  4. ivSkilled mimic of other birds, especially buzzards and owls

In the field

Field marks

  • aPinkish-buff body with a bright white rump contrasting with a black tail
  • bBlue-and-black barred patch on the wing
  • cBlack moustache stripe and streaked crest
  • dFloppy, rounded wings in flight
Voice
A harsh, tearing screech, 'skaaak', the alarm call of the woods; also soft mewing and mimicry.
Not to be confused with
No other European bird combines the white rump and blue wing patch. Hoopoe also shows a black-and-white pattern in flight but has a long, curved bill and fan crest. Middle Eastern races have a black crown.
Where to see it
Oak woods throughout Europe, most visible in September–October when carrying acorns.
When
Resident; occasional large irruptions in autumn when acorn crops fail

§8

Marginalia

The specific name 'glandarius' means 'of acorns', and the blue wing feathers were sold to Victorian milliners and fly-tyers; jays were persecuted by gamekeepers as egg thieves.

Curiosity

Studies at Cambridge showed male jays choose food gifts for their mates based on what the female has recently been eating, suggesting they track another bird's desires.
