Where To Find This Bird

This bird prefers freshwater habitats like lakes, ponds, marshes or rivers for breeding purposes. During migration periods or winter seasons when it moves southwards towards warmer climates along coastlines such as estuaries or mudflats.


Bonaparte’s Gulls feed primarily on insects but also eat aquatic creatures such as small fish and crustaceans by diving into shallow waters from above. They will also scavenge food from other birds or animals if necessary.
