Hydrophilous ornithofauna of the north-west Ladoga lake
// Biodiversity of Fennoscandia (diversity, human impact, nature conservation). Petrozavodsk: Karelian Research Centre of RAS, 1997.
Lake Ladoga is the largest lake in Europe. Majority of it's islands are situated in the North-West deepest part of the lake. The outer Valaam and West archipelagos consist of about 60 islands and islets and the inner Sortavala, Lahdenpohja and Pitkjaranta archipelagos (skerries) consist of several hundred islands and islets.
The data about aquatic and semiaquatic birds of this area were obtained from 1986 to 1997. During that time of observations 68 bird species were registered for the period from the end of April to the end of September. Among these species 34 are breeding ones, 9 - presumably breeding, 4 species (cormorant, bean goose, common scoter, gadwall) were breeding species in the past, 19 species are migrants and 9 out of them were met in summer also, 4 species (gray heron, red-breasted goose, ruddy shelduck and black tern) were rarely met birds.
The North-West part of Ladoga Lake is important breeding area for common tern, lesser black-backed gull and has biggest colonies of herring gull in Karelia and probably in the North-West Russia. In the beginning of 90s white-tailed eagle started nesting in the skerries after long period of absence. Number of osprey is equal 3-4 pairs. Many Arctic species nest within the archipelagos: common eider, velvet scoter, long-tailed duck, oystercatcher, turnstone, greater black-backed gull and arctic tern. The nesting of canada goose and caspian tern was recorded in Karelia and the North-West Russia for the first time. 22 bird species are listed into the Red Data Books of the Russia, Karelia and Finland.
The organising of protected nature territories is the real way to save unique hydrophilous ornitofauna of North-West Ladoga. The Valaam protected nature area was created in 1994 and the "Western Archipelago" landscape reserve was created in 1995. The organising Ladoga Skerries National Park will be next important step in this direction.
The work was supported by Federal Program "Biodiversity of Russia".
