The hooded crow (Corvus cornix), formerly regarded as a subspecies, has been split off as a separate species, and there is some discussion whether the eastern carrion crow (C. c. orientalis) is distinct enough to warrant specific status; the two taxa are well separated, and it has been proposed they could have evolved independently in the ...
However, some crows also eat many agricultural pests, including cutworms, wireworms, grasshoppers, and harmful weeds. [19] Some corvids will eat carrion , and since they lack a specialized beak for tearing into flesh, they must wait until animals are opened, whether by other predators or as roadkill.
The eastern carrion crow (Corvus corone orientalis, originally a separate species C.orientalis) is a member of the crow family and a subspecies of the carrion crow. Differences from the nominate subspecies include a larger size, at a length about 500 millimetres (20 in), and more graduated outer tail feathers .
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.
Liao and her colleagues trained three carrion crows, a European species closely related to the American crow, over more than 160 sessions. During the trainings, the birds had to learn associations ...
They can be distinguished from the common raven (C. corax) because American crows are smaller and the beak is slightly less pronounced; from the fish crow (C. ossifragus) because American crows do not hunch and fluff their throat feathers when they call; and from the carrion crow (C. corone) by size, as the carrion crow is larger and of a ...
