Résumé :	In former times, the Romanian Dobrodgea was famous for its enormous raptor populations, including several species that have now become very rare or even disappeared as breeding birds from the country. Seven expeditions from 1990-96 during the spring migration and early breeding period soon revealed that the area is still of great importance for raptors. A major European raptor flyway passes to the west of the Black Sea. Twenty-nine raptor species occur more or less regularly during spring migration in the Romanian Dobrodgea and the Razim-Sinoie lagoon system. Most birds follow the coastline on their way to the breeding grounds. The concentrated movements in the coastal strip of Bulgaria (after crossing the Bosphorus) appear to become somewhat more scattered in Romania. In some species, migration is more prominent in autumn than in spring, reflecting the situation in Bulgaria and at the Bosphorus. The Romanian Dobrodgea is assumed to be of particular importance as a regeneration and refueling area for migrating raptors. In this regard the Razim-Sinoie lagoon system is especially valuable due to its concentrations of waders and waterbirds and the abundance of rodents. Raptor populations in the Romanian Dobrogea are still considerable, though several species have seriously declined during the 20th century. At least 22 'Species of European Conservation Concern' (Tucker and Heath 1994) occur here, among them 14 confirmed or likely breeding species. Three of Romania's 37 species of recorded raptors are listed as vulnerable on a global scale (BirdLife International 2000): Spotted Eagle Aquila clanga, Imperial Eagle Aquila heliaca and Lesser Kestrel Falco naumanni. White-tailed Eagle Haliaeetus albicilla and Pallid Harrier Circus macrourus are regarded as near threatened. The degradation and loss of habitat as a result of intensified agriculture, forest management and illegal hunting are responsible for the continuing decline in many raptor species. Large numbers of birds are killed by overhead power lines. Efforts to protect the remaining natural habitats in E Romania need to be strengthened: The protection status of the most important areas for raptors is currently inadequate. E.g. only 11 ha of the IBA 'Niculitel and Babadag forest', an especially important area for breeding raptors with a total area of ca. 10,000 ha, is protected as a Nature Reserve. Ecologically sustainable land use practices, taking into account the habitat requirements of the raptors and other species of the Romanian Dobrogea, need to be implemented. Currently, uncontrolled hunting results in heavy losses to severely endangered species; this needs to be controlled more effectively.
