Corvus

Corvus is a genus of large passerine birds in the family Corvidae, to which ravens belong. As a group they demonstrate admirable examples of intelligenceand one of their species, the New Caledonian crow, has recently been intensively studied^[when?] for its ability to make and use their own tools to obtain their food. Ravens are now considered to be among the most intelligent animals in the world, with an encephalization ratio equal to that of many non-human primates.

All temperate continents (except, strangely, South America) and many oceanic islands (including Hawaii) have representatives of the more than forty members of their genus.

Crows appear to have evolved in central Asia and then extended their range to North America (including Mexico), Africa, Europe, and Australia.

They range in size from the relatively small pigeon-sized crow (Eurasian) to the common raven of the Palaearctic region and the thick-billed raven of the Ethiopian highlands.
