Slender-billed Gull

The Slender-billed Gull is a medium-sized species of Old World gull. Slender-billed Gulls breed along coastal areas of the Mediterranean, Black, and Caspian Seas, as well as the Persian Gull and inland lakes in parts of eastern Europe and central Asia.

Slender-billed Gulls feed on fish by diving into the water to catch suitable prey. They also feed on invertebrates sought via beak-probing into mud or sand. They may also feed on insects caught on the wing.
