Description
The brown-necked raven (Corvus ruficollis) is a larger bird (52–56 cm in length) than the carrion crow though not as large as the common raven. It has similar proportions to the common raven but the bill is not so large or deep and the wings tend to be a little more pointed in profile. The head and throat are a distinct brownish-black giving the bird its English name, while the rest of the plumage is black glossed with purple, blue or purplish-blue. Like the Common raven, Thick-billed raven and White-necked raven, it is one of the larger raven species. The smaller raven species are the Australian raven, Forest raven, Little raven, Fan-tailed raven and Chihuahuan raven with the Thick-billed raven being the world's largest raven species and the Chihuahuan raven being the smallest. The feathers of this species often fade quite quickly to a brownish black (even the truly black feathers) and the bird can look distinctly brown by the time it moults. The feet, legs and bill are black. The dwarf raven was formerly considered a subspecies (Corvus ruficollis edithae) but this bird now appears to be closer to the pied crow (C. albus) than this species.

Feeding Habits
Brown-necked Raven consumes a vast range of foods, including invertebrates, small vertebrates, and plant material. It exhibits diverse feeding behaviors such as foraging, scavenging, and occasionally hunting, even cooperating to flush prey. It also scavenges at human settlements and hides surplus food.
Habitat
Brown-necked Raven occupies predominantly arid landscapes such as semi-deserts, desert plains, and mountain foothills, as well as inhabiting dry savannas, oases, and areas around human settlements like rubbish dumps and army camps. These birds are adaptable and can also be found in barren islands that have some level of cultivation. They have a preference for regions with desert vegetation including tamarisk, saxaul, and wormwood shrubs. Although they can occur at elevations as high as 2000 meters, they tend to avoid mountainous zones where their range overlaps with that of C. corax, except in places where the latter species also resides in desert plains.
Dite type
Omnivorous
General Info
Distribution Area
This species has a wide range across virtually the whole of North Africa, down as far as Kenya, the Arabian Peninsula and up into the Greater Middle East and southern Iran. It lives in a predominantly desert environment visiting oases and palm groves. Food consists of a wide range of items, including carrion, snakes, locusts and other grasshoppers, stranded fish (in coastal areas), grain stolen from bags, dates and other fruits. It is quite fearless when not persecuted but is quick to become wary and shy if too much attention is paid to it. A 2009 Israeli study showed the species to cooperatively hunt lizards, with birds blocking exits while others hunted.
