Drvo sa gnezdima vrana.

Pogled na veliko drvo sa vranama, koje rave gnezda.
Vrana (лат. Corvus) je siroko rasprostranjeni rod ptica, porodice vrane (Corvidae). Latinski naziv roda Corvus u prevodu znaci „gavran”. U Evropi, naziv „vrana” se koristi da oznaci crnu vranu i sivu vranu. Vrste iz roda vrana (Corvus) cini trecinu ukupnog broja vrsta iz porodice vrane (Corvidae). Pokazalo se da je rod vrana evoluirao u Aziji u okviru porodice vrane, koja je evoluirala u Australiji.
Vrane su u opsegu velicina od relativno malih cavki velicine guluba. Oko 45 clanova ovog roda se javlja na svim kontinentima. Rod vrana čini trecinu vrsta u porodici Corvidae. Kolektivno ime grupe vrana je jato. Ime roda je latinska rec za gavrana.
Nedavna istrazivanja su utrvrdila da su neke vrste vrana sposobne ne samo da koriste orudja, vec i da konstruisu oruđa. Vrane se ubrajaju među najinteligentnije zivotinje na svetu, sa koeficijentom encefalizacije jednakim onom koji imaju mnogi primati ne racunajuci ljude.



Tree with crow's nests.

A view of a large tree with crows making nests.
The crow (lat. Corvus) is a widespread genus of birds, the family of crows (Corvidae). The Latin name of the genus Corvus means "raven". In Europe, the name "crow" is used to denote a black crow and a gray crow. Crow species (Corvus) make up one third of the total number of crow species (Corvidae). The genus Crow has been shown to have evolved in Asia within the crow family, which evolved in Australia.
Crows are in the range of sizes of relatively small jackdaws. About 45 members of this genus occur on all continents. The genus Crow makes up one third of the species in the family Corvidae. The collective name of the crow group is flock. The genus name is the Latin word for raven.
Recent research has shown that some species of crows are capable not only of using tools, but also of constructing tools. Crows are among the most intelligent animals in the world, with an encephalization rate equal to that of many primates, not counting humans.
