Tube-nosed seabirds are a group of seabirds that have a unique feature of having tubes on their beaks. One type of tube-nosed seabird is the petrel, which is a medium-sized bird with long wings and a hooked bill. Petrels are found in many parts of the world, including the Atlantic, Pacific, and Indian Oceans. They feed mainly on fish, squid, and crustaceans, and they often fly close to the surface of the water. Petrels are also known for their long-distance migrations, which can take them thousands of miles away from their breeding grounds.
