The Common Raven (Corvus corax) is a large black bird in the crow family, with iridescent feathers. The bill is large and slightly curved. At maturity, it is between 56 and 69 cm (22 to 27 inches) in length, with a wingspan double that.
Apart from its greater size, the Raven differs from its cousins the crows by having a larger and heavier beak, and a deeper and more varied barking prrrukk call note. Other field points are the shaggy throat feathers and a longer, wedge-shaped tail. The raven is the National bird of Bhutan because it adorns the royal hat, representing the deity Gonpo Jarodonchen (Mahakala with a raven's head); one of the important guardian deities of Bhutanese culture.
Much Raven behavior is believed to be related to mating and reproduction. Juveniles begin to court at a very early age, but may not bond with another bird for 2-3 years. Aerial acrobatics and displays of intelligence and ability to provide food are key behaviors of courting Ravens. Once paired, Ravens tend to nest together for life, usually in the same location. The pair will build a nest on cliff ledges or in tall trees (or building ledges in cities). Breeding pairs must have a territory of their own before they begin nest-building and reproduction, and the territory and its food resources will be defended against others. The nest is made of large sticks and twigs lined with a softer material, such as deer fur. 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. As with many birds, pairing does not necessarily mandate sexual monogamy, and raven habits show fluidity in this regard.
Ravens have a varied diet. They will eat a wide number of foods, including insects, berries, fruit, other birds' eggs, carrion, wolf or dog feces, and human-produced foods such as bread. They also may kill small birds and mammals, including young rabbits and rats, but do so mainly as opportunists. Popular beliefs about ravens include the notion that they are attracted to shiny objects, but research indicates that juveniles are deeply curious about all new things, and that Ravens retain an attraction to bright, round objects based on their similarity to bird eggs. Mature ravens lose their intense interest in the unusual, and become highly neophobic, taking up to three days to begin feeding on dead mammals. Ravens usually live ten to fifteen years in the wild, or twice that in captivity.
Ravens have impressed their biologist observers with their apparent intelligence and insight. Experiments have shown that members of the crow family are capable of using tools; an experiment, where some desirable item lay on the bottom of a bottle, showed that some of these birds were able to form a hook to reach the item. Like other corvids, Ravens can copy sounds from their environment, including human speech. They have a wide range of vocalizations, which remain the object of interest to ornithologists.
The Common Raven is the official bird of the Yukon and of the city of Yellowknife, Northwest Territories.
Because of its black plumage, croaking call, and diet of carrion, the raven has long been considered a bird of ill omen and of interest to creators of myths and legends.
In the New Testament as well, ravens are used by Jesus as an illustration of God's provision in Luke 12:24
William Shakespeare refers to the raven more often than to any other bird; Othello provides one example as well as Macbeth. The raven "Grip" is an important character in Charles Dickens' Barnaby Rudge. Edgar Allan Poe also used the raven as a supernatural messenger in his poem "The Raven". In this and the Dickens book, the bird's power of speech is important. Among other works of literature, Christopher Marlowe's play The Jew of Malta and Edmund Spencer's The Faerie Queene also employ the raven's darkly ominous image. News-bearing ravens also appear in The Hobbit, by J. R. R. Tolkien and Animal Farm by George Orwell. Raven is Hari Seldon's nickname in Isaac Asimov's Foundation Series. He gets it for his dire predictions of the future. The raven is featured prominently in the novel Jonathan Strange & Mr Norrell by Susanna Clarke, which relates a fictionalized history of England where magic is practiced and legend tells of "The Raven King", the one-time king of northern England. In Robert Jordan's Wheel of Time series, Ravens are used as the Dark One's eyes and ears, along with other carrion eaters, and occasionally even fatally attack. People with long black hair are sometimes poetically referred to as "raven-haired", referring to the coloring, and not to any actual raven's hair.
For instance, in the Tlingit culture, there are two different Raven characters which can be identified, although they are not always clearly differentiated. One is the creator Raven who is responsible for bringing the world into being and who is sometimes considered to be the same individual as the Owner of Daylight. The other is the childish Raven, always selfish, sly, conniving, and hungry.
Other notable stories tell of the Raven stealing and releasing the sun, and of the Raven tempting the first humans out of a clam shell.
