The Common Raven also known as the Northern Raven, is a large, all-black passerine bird found across the northern hemisphere, it is the most widely distributed of all corvids. The Common Raven has coexisted with humans for thousands of years and in some areas have been so numerous that they are considered a pest. Part of its success comes from its omnivorous diet; Common Ravens are extremely versatile and opportunistic in finding sources of nutrition, feeding on carrion, insects, cereal grains, berries, fruit, small animals, and food waste. Breeding pairs must have a territory of their own before they begin nest building and reproduction, and thus aggressively defend a territory and its food resources. Females lay between three to seven pale bluish-green, brown-blotched eggs. Incubation is about 18 to 21 days, by the female only. Young fledge at 35 to 42 days, and are fed by both parents. They stay with their parents for another six months after fledging.
