The seagull is a seabird, quite common in the Northern hemisphere. It usually lives in colonies near coastal areas and wetlands. Adults are usually white or gray, while different species are distinguished and identified based on the color of their heads and the shape of their beaks or their wings.
In winter, gulls who live on the mainland migrate to coastal areas, where they can locate their food easily: worms, insects, mollusks, and crustaceans on the beach, fish, and even garbage from ships. Some of the larger gulls eat the eggs of other birds, including their own species.
At the coastal areas and wetlands of Eastern Macedonia and Thrace, we find colonies of the species of the Mediterranean gull (Larus melanocephalus), of the black-headed gull (Larus ridibundus), and of the Caspian gull (Larus cachinans).
