Özdemir Adızel, a biology professor at Yüzüncü Yıl University in Van, told Anadolu Agency that the whooper swans came to the region to spend the winter this year as well.
Noting that most of the swans shelter on the shores of Ercis, Adızel said: "It is a species that migrates to our region to spend the winter. Towards the spring, they head north again. The species, also known as the white goose in the region, is under hunting pressure despite conservation efforts."
