Petrels are seabirds belonging to the family Procellariidae. They are known for their long wings and ability to glide over ocean waves for long distances. Petrels primarily feed on fish and squid, which they catch by diving or skimming the water's surface. They are often found in the Southern Ocean and around other coastal regions. These birds are also recognized for their unique breeding habits, often nesting in colonies on remote islands. Petrels are monogamous and typically return to the same nesting site each year. Their populations can be affected by environmental changes and human activities, such as fishing and pollution.
