JACKDAWS are two species of bird in the genus _COLOEUS_ closely related to,
but generally smaller than, crows and ravens (_Corvus_). They have a blackish
crown, wings, and tail, with the rest of their plumage paler.<ref name =
madge2>Madge & Burn (1994) 136–138. The word _Coloeus_ is Neo-Latin, from the
Ancient Greek for jackdaws: _[grc]_ ([grc]).[2][3] They come from Asia,
Europe, Africa and Siberia.
** Taxonomy
While some authors consider _Coloeus_ a subgenus of _Corvus_, others have
classified _Coloeus_ as a distinct genus in the family Corvidae.[4] Following
_Birds of South Asia: The Ripley Guide_,[5] the International Ornithological
Congress has also reassigned the two Jackdaw species from the genus _Corvus_
to the genus _Coloeus_.[6]

[Species table/end] 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 in Mongolia.<ref name = madge2/>
