About Eurasian Jay
This is a medium sized buffish to rufous or brownish-pink bird with blackish brown primary flight feathers and tail and bold white rump. The thirty three or so different geographical races vary in plumage details. Wings have black-barred bright blue patches and in most races white patches. Face varies from white to same color as body with a variable black mustache stripe; in European and some other races the forehead and crown is paler with black streak, in others it is black or unmarked. Some races have gray upper back; bill dark brown; eyes bluish-white, dark in some birds.
These birds breed in the spring and early summer. Both the male and female build a crude cup-shaped nest of twigs and stems in a small tree, and then the female lays 3-7 pale bluish, greenish or live-bluff eggs, densely speckled with brown. The female takes care of the eggs while the male feeds her. Once the chicks are born, they are taken care of by both the male and female.
This is one of the most beautiful of all the members of the crow family. This bird is usually shy and secretive, especially in Europe where it has been persecuted for its depredations on gamebird eggs and chicks.
The Eurasian Jay also plays a vital role in the natural role of planting oakwoods. In the fall, the birds gather vast numbers of acorns to see them through the hard times of winter. They will then carry them in their throat pouch far away to bury them in a secret hoard. The birds only eat a proportion of their stores and many of the abandoned acorns grow into new trees far from where they started out.
