Belongs within: Corvidae.
The crows of the genus Corvus are large, predominantly black passerine birds. Crows are mostly generalist feeders, and are found in most parts of the world. The largest species (and the largest-bodied of all passerine birds) is the raven Corvus corax, which is found scattered throughout the Palaearctic region.
The phylogenetic analysis by Burleigh et al. (2015) also suggests that the nutcrackers Nucifraga are placed within the Corvus clade; these are two species found in the Holarctic region, patterned in contrasting dark and pale colours, with relatively long, slender and pointed bills. Their diet contains a high proportion of conifer seeds, which they also sequester in caches. The nutcrackers may be related to the western jackdaw Corvus monedula, a relatively small crow with a short bill and grey nape found in the western Palaearctic.
