Why the angel tern is called so?

       The angle tern, also known as white tern, fairy tern and white noddy, is an all-white bird. The eyes of the bird are black which gives the bird another worldly appearance.

       The bird is found across the Pacific Ocean from the coasts of Chile and Colombia to New Zealand from china to India, the islands of the Indian ocean and the coast of South Africa. And wherever it stays, it chooses to stay in places with perfect sunshine and coral beaches. However, the bird is occasionally found in Japan, Madagascar, Mexico, and on some islands in the Atlantic Ocean.

       It feeds on ordinary fish and squid. It procures them by swooping down and snatching them from the water surface. The white tern has a wingspan between 76 and 87 centimetres and a long black bill. It was formally described by the Swedish naturalist Andres Sparrman in 1786.
