Common Loon – Water Connection, page 3

• A loon swallows most of its prey underwater, aided by sharp, rearward-pointing projections on the roof of its mouth and tongue that help it keep a firm hold on slippery fish.

• Loons have a special gland between their eyes that filters extra salt from their blood, so they don’t get sick while they drink ocean saltwater and eat ocean fish in the winter. This gland shrinks when loons return to fresh water habitats in the spring.

• A loon’s thick feathers are warm and waterproof, so even while swimming among ice floes in the Arctic Ocean, loons stay warm and dry.     next page >>
