The article presents generalised data on internationally important staging sites of Greylag Goose (Anser anser), Greater White-fronted Goose (Anser albifrons), Lesser White-fronted Goose (Anser erythropus), Bean Goose (Anser fabalis), Whooper Swans (Cygnus Cygnus) and Bewick's Swans (Cygnus bewickii) in the Neman River delta shared by Russia and Lithuania. The authors indicate the decrease in the population of Bean Geese along-side with the increase in the population of Greylag Geese, Whooper Swans, Bewick's Swans and particularly Greater White-fronted Geese. This pheno-menon is brought about by the global climate change, changes of the migratory flyways of certain species (particularly Greater White-fronted Goose) and by human impact. In order to preserve the wetland complex of utmost importance for mig-rating birds, it is necessary to develop the cross border Ramsar territory and to grant the corresponding status to the Russian part of the Neman delta.
