In spring and autumn a very special spectacle can be seen in Northern Germany: the migration of Common Cranes. Many thousands of these majestic birds rest in Northern Germany before they move to their breeding places in Scandinavia or their winter quarters in Southern Europe. Photopraphers of the bird photo stock agency BIA - birdimagency have captured moments of their migration in atmospheric silhouettes.
