The paper presents the data on species composition and relative numbers of diurnal birds of prey in the BerestovaRiver Basin (Kharkiv Region) collected in 2009-2011. The counts were taken from the second decade of May to the end of June. A total number of count days is 15, of them 9 days are in May, and 6 days in June. Main types of counts were automobile (over 300 km) and pedestrian (approx. 150 km) routes. The counts covered not more than 50% of the study area. The upper and middle parts of the river were investigated the most completely. A total of 207 territorial pairs of 10 birds of prey species were recorded. The dominant was the Buzzard (Buteo buteo). The Marsh Harrier (Circus aeruginosus) was numerous. The Long-legged Buzzard (Buteo rufinus) and Black Kite (Milvus migrans) are recorded rather often. Possibly, the Goshawk is a common species (Accipiter gentilis). Other species are rare. To our judgment, the BerestovaRiverValley is an important area for the conservation of such rare species as the Long-legged Buzzard, Montagu’s Harrier, Booted Eagle and Black Kite.
