It is one of the two largest corvids, alongside the thick-billed raven, and is the heaviest passerine bird; at maturity, the common raven averages in length and in weight, though up to in the heaviest individuals. Although their typical lifespan is considerably shorter, common ravens can live more than 23 years in the wild. Young birds may travel in flocks but later mate for life, with each

Taxonomy

The common raven was one of the many species originally described, with its type locality given as Europe, by
Carl Linnaeus Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming o ...

s. Gwinner carried out important studies in the early 1960s, recording and photographing his findings in great detail. Fifteen to 30 categories of calls have been recorded for this species, most of which are used for social interaction. Calls recorded include alarm calls, chase calls, and flight calls. The species has a distinctive, deep, resonant ''prruk-prruk-prruk'' call, which to experienced listeners is unlike that of any other corvid. Its very wide and complex vocabulary includes a high, knocking ''toc-toc-toc'', a dry, grating ''kraa'', a low guttural rattle and some calls of an almost musical nature. Like other corvids, the common raven can mimic sounds from their environment, including human speech. Non-vocal sounds produced by the common raven include wing whistles and bill snapping. Clapping or clicking has been observed more often in females than in males. If a member of a pair is lost, its mate reproduces the calls of its lost partner to encourage its return.

In his 1950 work, ''Grønlands Fugle'' 'Birds of Greenland'' noted ornithologist Finn Salomonsen indicated that common ravens did not overwinter in the Arctic. However, in Arctic Canada and Alaska, they are found year-round. Young birds may disperse locally. Goodwin, p. 139 In the United Kingdom, the range is currently increasing after improved legal protection, but illegal persecution by gamekeepers remains a problem in many areas. It favours mountainous or coastal terrain, but can also be found in parks with tall trees suitable for use as habitation. Its population is at its most dense in the north and west of the country, though the species is expanding its population southwards. Most common ravens prefer wooded areas with large expanses of open land nearby, or coastal regions for their nesting sites and feeding grounds. In some areas of dense human population, such as

in the United States, they take advantage of a plentiful food supply and have seen a surge in their numbers. On coasts, individuals of this species are often evenly distributed and prefer to build their nest sites along sea cliffs. Common ravens are often located in coastal regions because these areas provide easy access to water and a variety of food sources. Also, coastal regions have stable weather patterns without extreme cold or hot temperatures. In general, common ravens live in a wide array of environments but prefer heavily contoured landscapes. When the environment changes in vast degrees, these birds will respond with a stress response. The hormone known as

. Corticosterone is activated when the bird is exposed to stress, such as migrating great distances.


Behaviour

Common ravens usually travel in mated pairs, although young birds may form flocks. Relationships between common ravens are often quarrelsome, yet they demonstrate considerable devotion to their families.


Predation

Owing to its size, gregariousness and its defensive abilities, the common raven has few natural predators. Predators of its eggs and chicks include martens, large owls, and sometimes

Breeding

Juveniles begin to court at a very early age, but may not bond for another two or three years. Aerial acrobatics, demonstrations of intelligence , and ability to provide food are key behaviours of courting. Once paired, they tend to nest together for life, usually in the same location. Instances of non-monogamy have been observed in common ravens, by males visiting a female's nest when her mate is away. Breeding pairs must have a territory of their own before they begin nest-building and reproduction, and thus they aggressively defend a territory and its food resources. Nesting territories vary in size according to the density of food resources in the area. The nest is a deep bowl made of large sticks (up to 150 cm long and 2.5 cm thick) and twigs, bound with an inner layer of roots, mud, and bark and lined with a softer material, such as

fur. The nest is usually placed in a large tree or on a cliff ledge, or less frequently in old buildings or utility poles. Females usually lay between four to six (rarely two to seven) pale bluish-green, brown-blotched eggs. Incubation is about 18 to 21 days, by the female only. The male may stand or crouch over the young, sheltering but not actually

Common ravens can be very long-lived, especially in captive or protected conditions; individuals at the Tower of London have lived for more than 40 years. Their lifespans in the wild are shorter, typically 10 to 15 years. The longest known lifespan of a ringed wild common raven was 23 years, 3 months, which among passerines only is surpassed by a few Australian species such as the satin bowerbird.

Ravens are regular predators at bird nests, brazenly picking off eggs, nestlings and sometimes adult birds when they spot an opportunity. They are considered perhaps the primary natural threat to the nesting success of the critically endangered California condor, since they readily take condor eggs and are very common in the areas where the species is being re-introduced. On the other hand, when they defend their own adjacent nests, they may incidentally benefit condors since they chase

found that cereal grains were the principal constituent of pellets, though small mammals, grasshoppers, cattle carrion and birds were also eaten. One behaviour is recruitment, where juvenile ravens call other ravens to a food bonanza, usually a carcass, with a series of loud yells. In '' Ravens in Winter'', Bernd Heinrich posited that this behaviour evolved to allow the juveniles to outnumber the resident adults, thus allowing them to feed on the carcass without being chased away. A more mundane explanation is that individuals co-operate in sharing information about carcasses of large mammals because they are too big for just a few birds to exploit.Heinrich, B. (1999). ''Mind of the Raven: Investigations and Adventures with Wolf-Birds'' pp. 119–120. New York: Cliff Street Books. Experiments with baits however show that such recruitment behaviour is independent of the size of the bait. Furthermore, there has been research suggesting that the common raven is involved in seed dispersal. In the wild, the common raven chooses the best habitat and disperses seeds in locations best suited for its survival.

The brain of the common raven is among the largest of any bird species. Specifically, their hyperpallium is large for a bird. They display ability in problem-solving, as well as other

However, when one discovers a large carcass guarded by a pair of adult ravens, the unmated raven will return to the roost and communicate the find. The following day, a flock of unmated ravens will fly to the carcass and chase off the adults. Bickerton argues that the advent of linguistic displacement was perhaps the most important event in the evolution of human language, and that ravens are the only other

ability involved a piece of meat attached to a string hanging from a perch. To reach the food, the bird needed to stand on the perch, pull the string up a little at a time, and step on the loops to gradually shorten the string. Four of five common ravens eventually succeeded, and "the transition from no success (ignoring the food or merely yanking at the string) to constant reliable access (pulling up the meat) occurred with no demonstrable trial-and-error learning." This supports the hypothesis that common ravens are 'inventors', implying that they can solve problems. Many of the feats of common ravens were formerly argued to be stereotyped innate behaviour, but it now has been established that their aptitudes for solving problems individually and learning from each other reflect a flexible capacity for intelligent insight unusual among non-human animals. Another experiment showed that some common ravens could intentionally deceive their conspecifics. A study published in 2011 found that ravens can recognise when they are given an unfair trade during reciprocal interactions with conspecifics or humans, retaining memory of the interaction for a prolonged period of time. Birds that were given a fair trade by experimenters were found to prefer interacting with these experimenters compared to those that did not. Furthermore, ravens in the wild have also been observed to stop cooperating with other ravens if they observe them cheating during group tasks. Common ravens have been observed calling

to the site of dead animals. The wolves open the carcass, leaving the scraps more accessible to the birds. They watch where other common ravens bury their food and remember the locations of each other's food caches, so they can steal from them. This type of theft occurs so regularly that common ravens will fly extra distances from a food source to find better hiding places for food. They have also been observed pretending to make a cache without actually depositing the food, presumably to confuse onlookers. Common ravens are known to steal and cache shiny objects such as pebbles, pieces of metal, and golf balls. One theory is that they hoard shiny objects to impress other ravens. Other research indicates that juveniles are deeply curious about all new things, and that common ravens retain an attraction to bright, round objects based on their similarity to bird eggs. Mature birds lose their intense interest in the unusual, and become highly neophobic. The first large-scale assessment of ravens' cognitive abilities suggests that, by four months of age, ravens do about as well as adult

. Juvenile common ravens are among the most playful of bird species. They have been observed to slide down snowbanks, apparently purely for fun. They even engage in games with other species, such as playing catch-me-if-you-can with wolves, otters and dogs. Common ravens are known for spectacular aerobatic displays, such as flying in loops or interlocking talons with each other in flight. And often, ravens can be seen soaring over hilly or mountainous terrain, taking advantage of ridge lift. They are also one of only a few wild animals who make their own toys. They have been observed breaking off twigs to play with socially.

Across its range in the Northern Hemisphere, and throughout human history, the common raven has been a powerful symbol and a popular subject of mythology and folklore.
