Perched high in the mountains of Ethiopia, Eritrea and Somalia, the thick-billed raven holds the title of the world"s largest raven. At more than 70 centimetres in length and weighing over 1 kilogram, it is about a quarter heavier than the common raven. Its enormous, arched bill—pale at the base and close to 9 centimetres long—is the largest among perching birds. These ravens live mostly between 1,520 and 3,410 metres above sea level, found across farmland, rocky cliffs and even rooftops in mountain towns.
