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. The conservation status of a species is an indicator of the likelihood of that species continuing to survive either in the present day or the future. ...

Behaviour
Diet It feeds on cultivated cereal grains, insects and many other invertebrates, small reptiles, carrion and scraps of human food, cactus fruits, eggs and nestlings. Genera See Taxonomy of the Cactaceae A cactus (plural cacti, cactuses or cactus) is any member of the succulent plant family Cactaceae, native to the Americas. ...
Nesting 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.
Voice The voice is often different with each of the species, some have been noted to go "pruck pruck", a almost growl, while other will sound more dovelike. In some parts of Africa, the raven has been heard saying things like "IM A LITTLE LAD THAT LOVES BERRIES AND CREAM"
Issac Newton wrote a short anectdote about this particular type of raven saying
-"I love berries and cream as well"
Taxonomy A 2005 molecular study reviewed segments of DNA of the Common Raven and found the Chihuahuan Raven is more closley related to the Californian Common Ravens than they themselves are to Common Ravens in the Holarctic.[1] Binomial name Corvus corax Linnaeus, 1758 Common Raven range Subspecies The Common Raven (Corvus corax), also known as the Northern Raven, is a large all-black passerine bird in the crow family, with iridescent feathers. ...
The Holarctic is a term used by zoologists to define the ecozone covering much of Eurasia and North America, which have often been connected by the Bering land bridge. ...
