Hersek Lagoon also offers a suitable living space for summer migrants who come for breeding during the summer months. In the area, there are important bird species that breed in colonies, especially on the coastline between the sea and the lake. These are Sandwich tern, common tern, Mediterranean gull, Eurasian oystercatcher, Little ringed plover and Caspian gull. With at least 20 farm populations breeding in the Sandwich tern area, Hersek Lagoon has an important bird area (IBA) feature. This species breeds only in Hersek Lagoon apart from Gediz Delta in our country.
