With the support of Sakertour, the Carpathian International Environmental Association and the “Milvus Group” Bird and Nature Protection Association have launched the www.rarebirds.hu webpage in order to unite records of rare bird species recorded in the Carpathian Basin on a single data base. It is our opinion that ornithological data can be more informative if determined by natural geographical instead of political borders, giving a truer picture of the status of rare species. For the first time, records of rare birds from the whole area of the Carpathian Basin are gathered on one website. For details please visit the www.rarebirds.hu internet page.
