Meet the distinguished Eurasian Jay (Garrulus glandarius), a member of the Corvidae family that stands out with its captivating appearance. This remarkable bird is characterized by a thick black mustache and showcases a distinct black-and-white wing pattern with a stunning patch of blue on the shoulder.
The Eurasian Jay’s most striking feature is undoubtedly its bold black-and-white wing pattern, highlighted by the eye-catching blue patch that graces its shoulder. Both adult birds exhibit pinkish-grey to reddish-brown upperparts, with a white rump and uppertail coverts that contrast against a black tail. The upperwing is adorned with finely barred black primary and outer great covert feathers, set against a background of rufous lesser and median coverts. The rest of the upperwing features feathers that are black to grey-black, often with white bases or edges, creating a remarkable and conspicuous pattern during flight. The underparts resemble the mantle, while the vent and undertail coverts are white. The head boasts a distinctive black crown streaked with white, with the forehead, lores, eye area, chin, and throat all adorned in white. A prominent black malar stripe adds to its charismatic appearance, and the nape and head sides match the upperparts in coloration.
The robust bill is blackish, accompanied by whitish to buffy rictal bristles. The eyes are bluish-white, and the legs and feet take on a pinkish-brown hue. Juvenile Eurasian Jays resemble adults but possess darker body plumage, a grayer bill, bluer eyes, and brighter legs. By the first autumn, young birds start exhibiting irregular black barring on the blue wing patch.
The Eurasian Jay is a woodland bird with a vast range that stretches from western Europe and northwest Africa to the Indian subcontinent, extending further to the eastern seaboard of Asia and Southeast Asia. These adaptable birds can be found in various woodlands and forests, with a preference for trees such as beech, hornbeam, and oak. They can be spotted in parks, large gardens, orchards, and even at elevations up to 4000 meters.
In terms of behavior, the Eurasian Jay primarily feeds on invertebrates during the breeding and nesting seasons. They glean from foliage in trees and, like other members of the Corvidae family, they also prey on eggs and nestlings of other bird species. During autumn and winter, they switch to consuming seeds, berries, chestnuts, and acorns, often caching acorns for later consumption.The Eurasian Jay engages in various displays, including aggressive behaviors and courtship displays. They construct well-constructed twig platforms for their nests, situated in forks near the center of trees or lower crowns. Females lay 3-10 eggs and incubate them alone for 16-19 days. Chicks are fed by both parents and fledge 19-23 days after hatching. They remain dependent on their parents for 7-8 weeks before being chased away from the home range. Eurasian Jays can start breeding at one or two years of age.
These secretive and wary birds often remain hidden in dense foliage, occasionally appearing alone or in small family groups. During spring, unmated birds gather to attract mates, and in late summer and autumn, they form large communal roosts.Overall, the Eurasian Jay is common or locally abundant, and its populations have been increasing and are currently stable. The species is not considered threatened at this time.
