Wikipedia Abstract

The Chihuahuan raven (Corvus cryptoleucus) is a species of bird in the family Corvidae that is native to the United States and Mexico. It was formerly known as the American white-necked raven, and has the proportions of a common raven with a heavy bill, but is about the same size as a carrion crow, or slightly larger than the American crow (44–51 cm (17–20 in) long). The plumage is all-black with a rich purple-blue gloss in good light. Like the forest raven, little raven, fan-tailed raven and Australian raven, it is one of the smaller raven species. The larger species of raven are the common raven, thick-billed raven, white-necked raven and brown-necked raven, with the common and thick-billed ravens being the world's largest raven species and the little and fan-tailed ravens being the smal
