Discover fascinating gull-billed terns facts.

The gull-billed tern (Gelochelidon nilotica) is a species of bird that is native to North America. They mainly live around salt marshes, coastal areas, and mudflats and thrive in large colonies.

They are named after their stout bill and are usually of beautiful pale silver and white color. This bird belongs to the order Charadriiformes, family Laridae, and genus Gelochelidon.

Their diet can range from insects, crabs, and mollusks to fishes acquired from the surface of the water. Gull-billed terns are also known to have the least tern-like features, as they refuse to swoop into water to catch fish.

During the nesting months, male and female tern birds undergo a brief period of courting, during which they impress each other with postures and head bending. They build their nests out of mud and scraps and share the responsibilities of their young off-springs till they reach an age of about three months.

They are migratory birds which means they travel towards warmer areas during the winter season. While these birds are found in dense concentrations around North America, they can also be found in Australia and Asia.

Would they make a good pet?
