Crow, (genus Corvus), any of various glossy black birds found in most parts of the world, with the exception of southern South America. Crows are generally smaller and not as thick-billed as ravens, which belong to the same genus. A large majority of the 40 or so Corvus
species are known as crows, and the name has been applied to other,
unrelated birds. Large crows measure about 0.5 metre (20 inches) long,
with wingspans that can reach 1 metre (39 inches).
Crows feed chiefly on the ground, where they walk about purposefully. They are omnivores that enjoy meat and may even attack and kill young, weak animals. This habit makes them unpopular with farmers, as does the bird’s propensity to raid grain crops. Berries, insects, the eggs of other birds, and carrion are also eaten. Crows will make off with shreds of roadkill and store tidbits in trees, caching the meat like a leopard does for later consumption.
Sometimes they bury seeds or store them in crevices in bark. They
occasionally steal food from other animals, sometimes cooperating with
other crows to raid food from otters, vultures, and water birds.
