The "Little Tern" is a summer migratory bird inhabiting tropical and temperate regions, including Korea. Both male and female birds look alike with a white and grey body, a black head and black lines around the eyes. Its beak is yellow and the tip of its beak is blackish, but in winter the entire beak turns black. This bird feeds on small fish and lives on the sand and gravel along beaches and riverbanks. It lays 2 to 3 eggs and both male and female birds take turns sitting on the eggs. The eggs are bluish ash grey with speckles.
