Here are some fun facts about the common loon that you may or may not already know.
Unlike most birds the common loon does not have hollow bones. The loon has solid bones which give it more weight and reduce its buoyancy, making it easier to dive under the water. This additional weight also causes the loon to lay deeper in the water then many ducks or geese.
Loons are built for spending most of their life in the water. Their legs are located in the back of their body instead of underneath it. This helps them to dive under the water to depths as low as 200 feet below the surface. Their red eye helps them to see while under the water and locate prey such as fish, frogs and aquatic invertebrates. Projections on the roof of the mouth and the tongue help them to keep a hold of their slippery prey.
