Jackdaw
The Eurasian Jackdaw, Coloeus monedula is a species of bird in the Coloeus genus. It is closely related to the Daurian Jackdaw and the two form a species pair and are sometimes considered conspecific,[2] but they seem to replace each other geographically in vicinity of L Baikal and N Mongolia, meeting on very narrow front, but with very few reports of mixed pairings.[2]

Kryukov and Suzuki (2000) and Haring et al. (2007a) found that the jackdaws were rather distant from the other Corvus species.[3][4] They are split from Corvus into Coloeus, as recommended by Rasmussen and Anderton (2005).[5]

Description

It is smaller than crows and has a black plumage with smocky gray nape. The eyes are light blue.

Similar species

Bill is much more slender than Rook, Hooded Crow and Carrion Crow.[6] In flight, told apart by Hooded and Carrion by faster and slightly deeper wing beats of the proportionately somewhat longer and narrower wings,[6] also by broad but short neck, and by short bill that gives the bird a somewhat 'docked' appearance at front.[6] As a rule, also flies in denser flocks than crows (almost as pigeons), but flock formations can be similar.[6]
