Thick-billed Raven - Corvus crassirostris
The Thick-billed Raven, Corvus crassirostris (Corvidae) is a very large and distinctive looking African Crow. Along with the Common ravens, they have the distinction of being the largest of the Passeriformes, measuring 60 - 64 cm in length.
The two more distinctive features of this species are the white patch on the nape and neck, and its large, thickened, deeply curved and white-tipped bill, which has deep nasal grooves.
This beautiful crow can be found in the so called Horn of Africa, in Eritrea, Somalia, Sudan and Ethiopia.
