Huge lake of international importance located on the Russian--Estonian border, in a highly developed area.
Wetland of International Importance. Not less than 200000-300000 individuals of waterfowl stopover during spring migration. Important place for moulting waterfowl, notably Anas platyrhynchos, Aythya ferina, Aythya fuligula and Bucephala clangula. The narrow land-corridor between Chudskoe and Pskovskoe lakes acts as a major bottleneck for migrating birds: as many as 4 million (mainly passerines but also some raptors) have been estimated to pass in a single 5-hour period in early September.
