Study Area
Expansive territory (from River Volga upper reaches to the Kola Peninsula north) was surveyed during the course of summer and winter expeditions in the period from 1998 to 2018.

MODERN ABOUNDANCE AND DISTRIBUTION OF OSPREY (PANDION HALIAETUS) ON THE COASTS OF LARGE WATERBODIES OF RUSSIA’S NORTH-WEST In total 53060 km we recovered: -6860 of boat surveys, - 22500 km of car surveys, -2370 km snowmobile surveys, -Walking routes – 21 330 km - Territory of Vologda Lakeland was additionally surveyed from a helicopter in 1988, 1993, 1999, 2002 and 2008 (38 flight hours).

The western, southern and eastern coasts of the lake were surveyed in 2014, 2016 and 2018. In the surveyed area, 12-14 pairs of osprey were found (1.5 pairs/100 km2). Unlike other reservoirs, there is no tendency to form dense nesting colonies, nests are located at a distance of more than 4-5 km from each other. Data on abundance dynamics are absent.

4 Nesting density – 1,3 pairs/100 km2 The osprey is a characteristic species for the forest zone of the Kola Peninsula, however, its distribution is uneven, due to the availability of nesting trees.
What we do? Finding osprey nest locations and long-term monitoring of known nests Study of nesting biology and ecology Study of migration patterns and determination of wintering sites Population management (building nest platforms and reinforcement of known nests) Treatment and rehabilitation birds. Ecological education
Study of nesting biology and ecology Osprey nest biology was studied on selected nests in the Darwin reserve throughout 2013-2018 using camera traps Year
