Corvus albicollis (White-necked Raven)

Wikipedia Abstract

The white-necked raven (Corvus albicollis) is somewhat smaller (50–54 cm in length) than the common raven or indeed its nearest relative, the thick-billed raven C. crassirostris. Like the Common raven, Thick-billed raven and Brown-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.
