Jackdaws are two species of bird in the genusColoeus closely related to, but generally smaller than,crows andravens (Corvus). They have a blackish crown, wings, and tail, with the rest of their plumage paler.[2] The wordColoeus isNeo-Latin, from theAncient Greek for jackdaws:koloiós (κολοιός).[3][4] They come from Asia, Europe, Africa and Siberia.
While some authors considerColoeus a subgenus ofCorvus, others have classifiedColoeus as a distinct genus in the family Corvidae.[5] FollowingBirds of South Asia: The Ripley Guide,[6] theInternational Ornithological Congress has also reassigned the two Jackdaw species from the genusCorvus to the genusColoeus.[7]

The eastern species is smaller than the western jackdaw, and in eastern adults, the pale areas of the plumage are almost white, whereas in the western bird, these areas are pale grey. The iris is pale in western jackdaw and dark in Daurian jackdaw. The two species are otherwise very similar in shape, calls, and behaviour. There is an argument for lumping the subgenus members as one species, but they do not interbreed where their ranges meet inMongolia.[2]
