Every year, gulls migrating from Siberia travel more than 4,000 kilometers to reach the city of Shiraz, southern Iran, during the winter season.

Wintering species also include Spoonbill Platalea leucorodia, Osprey Pandion haliaetus, White-tailed Eagle Haliaeetus albicilla, and Terns Sterna spp to name a few.
