Bird migration: a novel theory for the evolution, the control and the adaptability of bird migration
P. Berthold, AuteurThe migratory behaviour of many bird species is currently changing, evidently in connection with global warming; in general there is a shift towards sedentariness. Because experimental studies indicate that all crucial aspects of migration are u[...]

P. Berthold, Auteur ; M. Kaatz, Auteur ; U. Querner, AuteurDuring satellite-tracking investigations of 140 white storks (Ciconia ciconia), one individual, the long-term world record holder among birds, was followed along 12 migratory journeys over a period of 10 years. This long-term study confirms what[...]
