Physical charateristics

Daurian Jackdaw has three distinct age-related plumages: both juveniles and adults are pied, but first-years have largely black plumage. Some authorities state that adults can occur in two plumage morphs, pied and all-dark; examination of almost 200 skins of Daurian jackdaws, however, showed that, without exception, all-dark individuals proved to be first-years, while pied individuals were adults. Furthermore, the head streaking of first-years, often mentioned as a key separation feature from Eurasian Jackdaw [G. monedula], varies according to time of year. As a consequence, first-winter Daurian jackdaws may be overlooked in Europe.

Habitat

Inhabits open woodland, river valley and open hills and mountains. The only other pied species around is the Chinese Collared Crow (C. torquatus) but as this is a much larger bird (about the same size or slightly larger than the Carrion Crow (C. corone)) confusion is unlikely to occur. Binomial name Corvus torquatus Lesson, 1830 The Collared Crow (Corvus torquatus) is about the same size or slightly larger (52-55 cm in length) than the Carrion Crow with proportionately slightly longer wings, tail and bill. … Binomial name Corvus corone Linnaeus, 1758 Carrion Crow range The Carrion Crow, Corvus corone, can be distinguished from the Raven by its size (48
