Migrating swans enter Mazandaran Province

The first flocks of migratory swans have entered the Sorkhroud Lagoon in Mazandaran Province.

Every year, with the increase of cold in the north of Caspian and parts of Siberia, migrating swans start migrating to low latitudes from mid-November with a small population.

In February, after three months of wintering, they start migrating to the Siberian regions.
