As a group they show remarkable examples of intelligence; it would not be at all an exaggeration to characterize crows as being to birds what higher primates (including humans) are are to mammals. They also top the avian IQ scale[1]. Crows and ravens often score very highly on intelligence tests. Crows in the northwestern US (a blend of Corvus brachyrhynchos and Corvus caurinus) show modest linguistic capabilities and the ability to relay information over great distances, live in complex, hierarchic societies involving hundreds of individuals with various "occupations", and have an intense rivalry with the area's less socially-advanced ravens. 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 search for food.
