Many birds leave our country for Southern Europe and Africa. Some of them stay, but at the same time, others arrive to take their place. These birds come to us from the North. They are usually rooks, for whom our winter is not too difficult.Rooks are very noisy, especially in their breeding colonies and roosting sites. They emit a characteristic, deep and hoarse "kraa kraa" or a gentler "grab grab".Would you like to compare the rook with another crow species, for example, the hooded crow, to find out how to distinguish them in the field?
