Stock Photo - 17 April 2022, Brandenburg, Schenkenberg: A Corn Bunting is gently held in the hand by a bird ringers. A ringing campaign took place in the Rietzer See nature reserve over Easter. The birds are caught with nets, measured, weighed and ringed by trained bird ringers. The nets are checked continuously during the campaign so that the birds are not exposed to unnecessary stress for a long time. The data is then entered into a central database at the Hiddensee ringing center. Thanks to the many volunteers in Germany, conclusions can be drawn about the breeding and migration behavior of the songbirds. Photo: Ingolf König-Jablonski/dpa/ZB. - Schenkenberg/Brandenburg/Germany
