Shearwater is a type of SEABIRD that is found in many parts of the world. It is a medium-sized bird with long wings and a pointed bill. The shearwater is a strong flier and can often be seen skimming the surface of the water. It feeds mainly on small fish, squid, and crustaceans. Shearwaters are also known as 'skimmers' due to their habit of skimming the surface of the water while searching for food.
