| Corvus cryptoleucus Couch , 1854 |
The Chihuahuan Raven (Corvus cryptoleucus), formerly known as the American White-necked Raven, has the proportions of a Common Raven with a heavy bill, but is about the same size as a Carrion Crow, or slightly larger (44-51 cm in length) than the American Crow. The plumage is all-black with a rich purple-blue gloss in good light. The nasal bristles extend farther down the top of the bill than in any other Corvus species to about two-thirds the length. The base of the neck feathers are white (seen only when ruffled in strong wind). The bill, legs and feet are black.
It occurs in the southwestern United States and Mexico including southeastern Arizona, southern New Mexico, northeastern ColoradoThere are also three Colorado Rivers: two in the United States and one in Argentina. Colorado is a state in the western United States. The name of Colorado came from the Spanish word "colorado" which means "reddish color".

For the Texas town, see Cactus, Texas. Many, see text A cactus (plural, cacti or cactuses) is a type of (usually) succulent plant belonging to the dicotyledonous flowering plant family, Cactaceae . The Cactaceae has fruits, eggs and nestlings.
The nest is built in either trees, large shrubs or sometimes even in old buildings. There are usually 5-7 eggs laid relatively late in the year during May so as to take advantage of the insect food for their young in their more arid environment.
The voice is similar to the Common Raven with "pruk-pruk" sounds and other croaks but is not as deep in tone or as varied in range.
