Petrels are a type of seabird that are known for their far-flying capabilities. They are found in many parts of the world, including the Atlantic, Pacific, and Indian Oceans. They are small to medium-sized birds with long wings and short legs. They feed mainly on fish, squid, and crustaceans. Petrels are also known for their ability to fly long distances over open ocean, often traveling hundreds of miles in a single day.
