Crows are incredibly intelligent animals. Their societies are complex and hierarchic. One North American species the New Caledonian Crow has developed tool making capacities (once thought to be only present in higher primates) and the Hooded Crows of Israel have been known to use bread crumbs for fishing. This level of intelligence is attributable to their enlarged frontal lobe, a characteristic found in only two other bird species, Ravens and Parrots.
