Crow
Crows form the genus Corvus in the family Corvidae. Ranging in size from the relatively small pigeon-size jackdaws (Eurasian and Daurian) to the Common Raven of the Holarctic region and Thick-billed Raven of the highlands of Ethiopia, the 40 or so members of this genus occur on all temperate continents (except South America) and several offshore and oceanic islands (including Hawaii). In the United States and Canada, the word "crow" is used to refer to the American Crow.[citation needed]
The crow genus makes up a third of the species in the Corvidae family. Other corvids include rooks and jays. Crows appear to have evolved in Asia from the corvid stock, which had evolved in Australia. A group of crows is called a flock or a murder, because the group will sometimes kill a dying crow.
Recent research has found some crow species capable not only of tool use but of tool construction as well. Crows are now considered to be among the world's most intelligent animals. The Jackdaw and (along with its fellow corvid, the European Magpie) has been found to have a neostriatum approximately the same relative size as is found in chimpanzees and humans, and significantly larger than is found in the gibbon.
