Habits & Behavior

Common Loons are exceptional divers and skilled hunters. They use their powerful legs, positioned far back on their bodies, to propel themselves underwater with great speed. While this makes them excellent swimmers, it also means they are awkward walkers on land.

These birds are highly territorial during the breeding season. Pairs defend their lake territories using loud and distinctive calls. Their nests are usually built close to the water’s edge, allowing them easy access to escape predators.

Common Loons are also known for their strong pair bonds, with many pairs returning to the same lake year after year to breed. Parents actively care for their chicks, and young chicks are often seen riding on their parents’ backs for warmth and protection.

During migration, they travel long distances from northern lakes to coastal regions, where they spend the winter months before returning to breeding lakes in spring.
