Post-breeding migration of Night Herons Nycticorax nycticorax tracked by GPS/GSM transmitters

Abstract


The migratory strategy of herons is poorly understood: only that of Purple Heron has been well studied. The migratory movements of three Night Herons from the Upper Vistula Valley (Poland) were studied using a GPS/GSM-tracking system in 2012. The results document a previously unknown autumn migration strategy of Night Herons with long stopovers en route, unlike that of Purple Herons. The different migration strategies of Purple Herons and Night Herons could be due to differences in wing-loadings and foraging ecology.
