Thick-billed Raven 
Conservation status Scientific classification Kingdom: Animalia Phylum: Chordata Class: Aves Order: Passeriformes Family: Corvidae Genus: Corvus Species: C. crassirostris Binomial name Corvus crassirostris
Rüppell, 1836
The Thick-billed Raven (Corvus crassirostris), a Corvid from the Horn of Africa, shares with the Common Raven the distinction of being the largest in the Corvid family, and indeed the largest of the bird order Passeriformes (perching birds). They measure 60-64 cm (24-25 in) in length and weigh 1.5 kg (3.3 lbs). It has a very large bill that is laterally compressed and is deeply curved in profile giving the bird a very distinctive appearance. This bill is black with a white tip and has deep nasal grooves with only light nasal bristle covers.
This raven has very short feathers on the head, throat and neck, which on the throat and upper breast have an oily brown gloss. The rest of the bird is glossy black except for a distinctive white patch of short feathers on the nape and onto the neck.

Distribution and habitat
Its range covers Eritrea, Somalia and Ethiopia; its habitat includes mountains and high plateau between elevations of 1500 to 3400 metres.
Behaviour
Diet
The Thick-billed Raven is omnivorous, feeding on grubs, beetle larvae from animal dung, carrion, scraps of meat and human food. It has been seen taking standing wheat. When seeking food from dung, it has been seen using a distinct scything movement to scatter the dung and extract the grubs.
Nesting
It nests in trees and on cliffs, apparently building a stick nest like the similar White-necked Raven. It lays three to five eggs.
Voice
Its calls include a harsh nasal croak, a low wheezy croak, a "raven-raven", and sometimes a "dink,dink,dink" sound.
