Corvus ruficollis (Brown-necked Raven)

Wikipedia Abstract

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.
