On Lake Kovsh in the city of Saki, all the swans died. There is a suffocating smell near the lake, “Vesti-Krym” reports. In addition to this, other birds of the reservoir died. Veterinarians ruled out the version with the disease of birds. At the end of September, a massive death of birds occurred in the north of Crimea, on the Sivash Bay. There, the birds died precisely because of the infection.
