Résumé :

In total, 29 diurnal raptor species and 13 owl species have been registered in Belarus. Of these, 20 and 10 species, respectively, are regular breeders in the country. Nine birds of prey and six owl species have been monitored during the past 40 years with variable degrees of intensity. Now, at the beginning of 2012, monitoring of seven diurnal raptor (Osprey Pandion haliaetus, Golden Eagle Aquila chrysaetos, Marsh Harrier Circus aeruginosus, Greater Spotted Eagle A. clanga, Lesser Spotted Eagle A. pomarina, White-tailed Eagle Haliaetus albicilla, Kestrel Falco tinnunculus) and four owl species (Tawny Owl Strix aluco, Tengmalm's Owl Aegolius funereus, Great Grey Owl Strix nebulosa, Pygmy Owl Glaucidium passerinum) is about to be continued at the same level. The population of the globally threatened Greater Spotted Eagle is in the process of most careful monitoring in comparison with other species. The main users of the data obtained through monitoring are the Ministry of Natural Resources and Environmental Protection of the Republic of Belarus, the Institute of Zoology (National Academy of Sciences), administration of the Strictly Protected Areas and NGO APB - BirdLife Belarus. Since 2006, monitoring of certain raptors has been included into a scheme of the National System of Environmental Monitoring in the Republic of Belarus. This national monitoring programme was fully funded during 5 years (2006-2010). Owing to the economic crisis and lack of sufficient financial support for research, this programme has eventually been reduced to monitoring of the Greater Spotted Eagle only. All other monitoring studies carried out in 2011 were only partial, as personal initiatives by some dedicated ornithologists on voluntary basis.
