A general term for birds in the family Lynchopidae of the order Charadriiformes. Three species are known worldwide. With long, slender bodies and wings, they look very similar to terns (family Laridae). They have short legs. The upper sides of the wings and back are blackish, while the undersides are white. A notable feature of birds in this family is the shape of their beak, with the lower beak being much longer than the upper beak. They insert this long lower beak into the water surface and fly low over the surface in that position, cutting through the water with their beak. When a small fish or shrimp gets caught in the lower beak, they grab it in their mouth. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
