The territory of the steppe pine forests in the Northeast of Kazakhstan has been surveyed in 13-23 May 2005. The total length of survey routes was 1172,6 km. The total length of edges of pine forests available for raptors in the region measured 1782,02 km, the length of the surveyed edges of pine forests was 809,53 km (45,43%). The Short-Toed Eagle (Circaetus gallicus). Two living nests were found in steppe pine forests in the Northeast of Kazakhstan. All nests were located on pines. A total of 3-5 breeding pairs are extrapolated for the region. The Great Spotted Eagle (Aquila clanga). A total of 3 breeding areas were found on the territory of the steppe pine forests in the Northeast of Kazakhstan, 2 living nests located on pines were found. The internal edge of pine forests have numbers of Great Spotted Eagle about 1,08 pairs per 100 km. A total of 7-15 breeding pairs are estimated in the Altai Krai. The Imperial Eagle (Aquila heliaca). A total of 60 breeding areas were found on the territory of the pine forests in the Northeast of Kazakhstan. There, 65 nests were found (47 active). All nests were located on pines (on tops of trees 73,85%). Clutches size (n=2) was 2 eggs. The internal edge of pine forests have numbers of Imperial Eagle about 4,68 pairs per 100 km, the external edge of pine forests 8,28 pairs per 100 km. The maximum local density of Imperial Eagles was recorded in external edge of pine forests. The nearest neighbor distance was 5,7±2,91 (M±SD), N=60, range 1,4 to 11,8 km. A total of 126-133 breeding pairs are estimated for the steppe pine forests in the Northeast of Kazakhstan. The Golden Eagle (Aquila chrysaetos). One young dead from electrocution was observed in the north edge of pine forest near Sariozek village. The sitting place of adult bird was observed in the internal edge of pine forest near Shalday village. The Saker Falcon (Falco cherrug). A total of 20 territories were found in the steppe pine forests in the Northeast of Kazakhstan in 2005. There, 18 nests were found (10 active). There, 17 nests were located in Imperial Eagle nests on pines and one nest was located in Great Spotted Eagle nest on pine. The internal edge of pine forests have numbers of Sakers about 0,36 pairs per 100 km, the external edge of pine forests 3,39 pairs per 100 km. The maximum local density of Sakers (90% breeding territories) was recorded in external edge of pine forests. The nearest neighbor distance was 13,71±7,82 (M±SD), N=20, range 4,45 to 34,36 km. A total of 39-42 breeding pairs are estimated for the steppe pine forests in the Northeast of Kazakhstan. The Eagle Owl (Bubo bubo). A total of 11 breeding areas were found on the territory of the steppe pine forests in the Northeast of Kazakhstan. There, 15 nests were found (2 living nests). All nests were located on the ground in the foot of pine-trees. Two broods contained 3 chicks each. A total of 73-83 breeding pairs are estimated to breed in the steppe pine forests in the Northeast of Kazakhstan.
