Fan-tailed raven
The fan-tailed raven (''Corvus rhipidurus'') is a passerine bird of the crow family native to Eastern Africa and the Arabian Peninsula. Like the Forest raven, Little raven, Australian raven and Chihuahuan raven, it is one of the smaller raven species. The larger species of raven are the Common raven, Thick-billed raven, White-necked raven and Brown-necked raven with the Common and Thick-billed ravens being the world's largest raven species and the Little and Fan-tailed ravens being the smallest, in fact it is about the same size or slightly larger than the carrion crow (47-51 cm) but with a much thicker bill, shorter tail and much larger wings.
==Description==
The fan-tailed raven is completely black including bill, legs and feet and the plumage has a purplish-blue gloss in good light. Worn plumage is slightly coppery-brown. The base of the feathers on the upper neck are white and only seen if the bird is inspected or a strong gust blows them the wrong way. The throat hackles are shorter than in most other ravens.
The voice is described as guttural croaks mixed with the sound of frog-call. Like all corvids, the Fan-tailed raven is capable of vocal mimicry, however this behavior is mostly recorded in captivity and, very rarely, in the wild.
