The Least Tern is a small seabird known for its slender body and pointed wings. It typically measures about 8 to 9 inches in length and has a distinctive black cap on its head. These birds are often found along sandy beaches and coastal areas, where they nest in colonies. Least Terns primarily feed on small fish and invertebrates, which they catch by diving into the water. They are known for their agile flight and can be seen hovering before plunging down to catch their prey. Conservation efforts are important for this species, as their nesting habitats are threatened by human activities and natural disturbances.
