![The Paleocene Waimanu (an early member of the Sphenisciformes) resembled loons in some aspects of its head and bill, but it was already flightless and used its feet for steering rather than propulsion](/Images/godic/202501/14/Waimanu_BW4014.jpg")
The loons (North America) or divers (UK/Ireland) are a group of aquatic birds found in many parts of North America and northern Eurasia. All living species of loons are members of the genus Gavia, family Gaviidae and order Gaviiformes.
