Young Storks (IMAGE) Max-Planck-Gesellschaft Caption A few week-old young storks in their nest, which were equipped with transmitters. The transmitters, weighing less than 60 grams, record the GPS coordinates and the acceleration of the birds. The latter piece of information tells the researchers whether an animal is flapping its wings or whether it is gliding. Credit MaxCine/ Ch.
