Divers, also commonly known as loons, are water birds found in north America, Europe and Asia. There are five living species all in the same family (gaviidae) and order (gaviiformes). All divers sit low in the water and have a body shape that's streamlined for diving. They are also powerful underwater swimmers. Their distinctive calls include hoots, tremoloes, yodels and a wail that sounds oddly similar to a wolf's howl.
