Annotation

In the past, the Carrion Crow (corvus corone corone) and the Hooded Crow (Corvus corone cornix) were considered as subspecies of the corvus corone. The Carrion Crow (Corvus corone) and the Hooded Crow (Corvus cornix) are now regarded as independent species. [1,2]
Since the species are genetically very similar, they can successfully mate with one another. The hybrids of the Carrion and Raven Crows are also fertile.
While the Carrion Crows mainly occurs in western and south-western Europe, the Hooded Crows are common in northern, eastern and south-eastern Europe. The species mix in the contact zone of the two populations, which runs through Germany.
The last pictures show a hybrid, which was living together with the Carrion Crow on the previous picture.
