Identification
Also called the Daurian Jackdaw, the Daurian Jackdaw is part of the corvid family. Its name comes from the Dauria region to the east of Russia. It is the same size, or slightly smaller, than the Carrion Crow. Its proportions and habits are also the same. However, it differs in its plumage. Many adults (but not all) have a creamy white chest, belly and nape. The white of the nape joins that of the chest forming a wide collar. The head, back, throat, wings, tail, ventral and under-tail are shiny black. A tinged gray area is visible at the back of the eye. Adults entirely black and juveniles are distinguished from the Carrion Crow by the black color of their iris (the Carrion Crow has a light gray iris).
The collared crow is the only other corvid species, sharing the same territory, which is bicolor, but its much larger size makes confusion with the Daurian Jackdaw unlikely.

Habitat
The Daurian Jackdaw lives in open woods and on cultivated lands of valleys, hills or mountains.
Behaviour character trait
It is a very sociable and gregarious bird, often in association in the winter with other corvids. Roosts can gather several hundreds of individuals. It nests in small colonies and couples are united for life.
Flight
The flight of the Daurian Jackdaw is direct. The wingbeats are faster than in other corvids.
Dietfeeding habits
The Daurian Jackdaw is omnivorous with a preference for plants. Its food is practically identical to that of the Common Jackdaw. It includes cereals, insects, berries and animal droppings. It does not disdain worms and snails.
Reproduction nesting
The Daurian Jackdaw is a cave-dweller. It nests in the crevices, which are well hidden, of trees or in the cavities of cliffs and ruined buildings.
