Common Loon

|
Gavia immer |
The eerie yodel of the Common Loon is a symbol of the wild North. The territorial call of the male loon can be heard from lakes across Canada to the very northern United States.
Interesting Information
The Common Loon swims underwater to catch fish, propelling itself with its feet. It swallows most of its prey underwater. The loon has sharp, rearward-pointing projections on the roof of its mouth and tongue that help it keep a firm hold on slippery fish.
Migrating Common Loons occasionally land on wet highways or parking lots, mistaking them for rivers and lakes. They become stranded without a considerable amount of open water for a long takeoff. A loon may also get stranded on a pond that is too small.
Loons are water birds, only going ashore to mate and incubate eggs. Their legs are placed far back on their bodies, allowing efficient swimming but only awkward movement on land.
The Common Loon is flightless for a few weeks after molting all of its wing feathers at the same time in midwinter.
