The petrel is a type of seabird belonging to the family Procellariidae. These birds are known for their long wings and ability to glide over ocean waves for long distances. Petrels are typically found in the Southern Hemisphere, although some species can be seen in the Northern Hemisphere as well. They feed primarily on fish and squid, which they catch while flying over the water. Petrels are often associated with storms, as they can be seen flying in rough weather. They have a unique way of navigating, using their keen sense of smell to locate food. Many species of petrels are migratory, traveling thousands of miles between breeding and feeding grounds.
