Terns are a group of seabirds belonging to the family Sternidae. They are known for their slender bodies, long wings, and pointed beaks. Terns are often found near coastal areas, lakes, and rivers, where they feed primarily on fish and small invertebrates. They are skilled fliers, capable of diving into the water to catch their prey. These birds are typically white or gray, with some species displaying black caps on their heads. Terns are social creatures, often nesting in colonies on sandy beaches or islands. They are migratory, traveling long distances between breeding and wintering grounds, similar to seabirds like gulls.
