It can be distinguished from the common raven by its size of around 48–52 centimetres (19–20 in) in length as compared to an average of 63 centimetres (25 inches) for ravens, and from the hooded crow by its black plumage. The carrion crow has a wingspan of 84–100 centimetres (33–39 in) and weighs 400–600 grams (14 oz – 1 lb 5 oz).
Crows, along with other members of the Corvidae family, are some the smartest animals on Earth. A new study shows that crows, in this case the carrion crow, can count out loud just like human ...
Hooded crow (Corvus cornix) in flight Jungle crow (Corvus macrorhynchos) scavenging on a dead shark at a beach in Kumamoto, Japan. Medium-large species are ascribed to the genus, ranging from 34 cm (13 in) of some small Mexican species to 60–70 cm (24–28 in) of the large common raven and thick-billed raven, which together with the lyrebird represent the larger passerines.
They can take over old nest sites of the black woodpecker (Dryocopus martius) [67] and stock dove (Columba oenas). [62] Breeding colonies may also edge out those of the red-billed chough, but in turn be ousted by larger corvids such as the carrion crow, rook or magpie. [62] Nests are lined with hair, wool, dead grass and many other materials. [68]
Pair of crows chasing away a red-tailed hawk from their nest. The American crow (Corvus brachyrhynchos) is a large passerine bird species of the family Corvidae. It is a common bird found throughout much of North America. American crows are the New World counterpart to the carrion crow and the hooded crow of Eurasia; they all occupy the same ...
The nest resembles that of the carrion crow, but on the coast, seaweed is often interwoven in the structure, and animal bones and wire are also frequently incorporated. [ 18 ] [ 20 ] The four to six brown-speckled blue eggs are 4.3 cm × 3.0 cm ( 1 + 3 ⁄ 4 in × 1 + 1 ⁄ 8 in) in size and weigh 19.8 g ( 11 ⁄ 16 oz), of which 6% is shell ...

The black-headed gull is a species which aggressively engages intruding predators, such as carrion crows. Classic experiments on this species by Hans Kruuk involved placing hen eggs at intervals from a nesting colony, and recording the percentage of successful predation events as well as the probability of the crow being subjected to mobbing.
