This species, like all divers, is a specialist fish-eater, catching its prey underwater, diving as deep as 200 feet (60 m). The bird needs a long distance to gain momentum for take-off, and is ungainly on landing. Its clumsiness on land is due to the legs being positioned at the rear of the body: this is ideal for diving but not well-suited for walking. When the birds land on water, they skim along on their bellies to slow down, rather than on their feet, as these are set too far back. The loon swims gracefully on the surface, dives as well as any flying bird, and flies competently for hundreds of kilometers in migration. It flies with its neck outstretched, usually calling a particular tremolo that can be used to identify a flying loon. This diver is well-known in Canada, appearing on the "loonie" coin and the previous series of $20 bill, and is the provincial bird of Ontario. Also, it is the state bird of Minnesota.
