Crow

The true crows are in the genus Corvus; they are large Passerine birds. As a group they show remarkable examples of intelligence and one species, the New Caledonian Crow, has recently been intensively studied because of its ability to manufacture and use its own tools in the day-to-day finding of food.

All temperate continents (except, surprisingly, South America) and several offshore and oceanic islands (including Hawaii) have representatives of the 40 or so members of this genus.

Crows appear to have evolved in central Asia and radiated out into North America (including Mexico), Africa, Europe, and Australia.

They range in size from the relatively small pigeon-sized jackdaws (Eurasian and Daurian) to the Common Raven of the Palearctic region and Thick-billed Raven of the highlands of Ethiopia.
