The Common Loon is one waterfowl many Canadians are familiar with. Any lake they are successful at, is a great indicator of the quality and the clarity of that water. Thanks to the clear water mountain lakes, more than a few times I have seen what a great swimmer the loons are. Everything about them is designed to be in the water, only time coming out when they are going and coming from their nest. And the nest is always next to the water. Their bones are denser than the bones of other birds, making them less buoyant but very handy for diving. With their legs placed near the back, they are able to move quickly through the water to catch their food. Loon parents and two chicks can put away about 450 kg of fish over a 15-week period.
