Unlike other waterfowl, loons share incubation duties and the male will sit on the nest just as often as the female.
Loons prefer to nest in quiet, secluded areas protected from wind.
Most often they will choose an island, which also protects them from terrestrial predators. Many different materials are used in building a nest. Usually it consists of items found in the immediate vicinity of their nesting site, such as grass, sedge, moss and mud.
