In the recent years, during winter about 5000 swans migrate from Siberia to the wetlands of the Caspian town of Sorkhroud in northern Iran. The swans return back to Siberia after the the cold season ends. The swans bring life and beauty to the wetlands and attract many visitors. Environmental activists are also busy trying to educate the public to be a good host to their guests!
