Natural History
The carrion crow (Corvus corone) is a passerine bird of the family Corvidae, native to western Europe and the eastern Palearctic. Along with the hooded crow (Corvus cornix), the carrion crow occupies a similar ecological niche in Eurasia to the American crow (Corvus brachyrhynchos) in North America. The two species look very similar to one another, but can be differentiated by size, as the carrion crow is larger and of a stockier build compared to the American crow.
