The Common Raven (Corvus corax) is a large black bird in the crow family, with iridescent feathers. The bill is curved. At maturity, they are between 60 and 78cm (24 to 27 inches) in length, with a wingspan double that.
Apart from their greater size, Ravens differ from their cousins the crows by having larger and heavier beaks, and with a deeper and more varied caw. Other field points are the thick throat and wedge-shaped tail.
Ravens can thrive in varied climates. They range from the Arctic to the deserts of North Africa, and to islands in the Pacific OceanFor other meanings of pacific see pacific (disambiguation). The Pacific Ocean (from the Spanish Pacifico meaning peaceful is the world's largest body of water. It encompasses a third of the Earth's surface, having an area of 179. 7 million kmē (69. 4 mill, indeed this species has the largest range of any member of the genus. Most Ravens prefer wooded areas (with large open land nearby) or coastal regions and in mountains for their nesting sites and feeding grounds.
Mated Ravens tend to nest together for life. The pair will build a nest on cliff ledges or in trees. The nest is made of whatever materials may have caught the builders' eyes. Ravens are known for their love of shiny objects. The female will lay from three to seven pale bluish-green, brown-blotched eggs. Both parents keep the eggs warm, and take turns feeding the chicks.
Ravens have a varied diet. They will eat anything edible, including insects, berries, fruit, other birds' eggs, carrion, and the garbage from human homes. They also kill small birds and mammals, including young rabbits and rats.
