Autumn crane migration and climate change in the Carpathian Basin
Abstract Weekly counts of roosting cranes were conducted between 2006–2014 in all significant stopover sites of Common Cranes (Grus grus) in Hungary, as an extension of the survey programme performed in Hortobágy National Park since 1994. As a result, I detected consistently asymmetrical migration p...
