Episode description
While many birds have hollow bones that make flying a breeze, diving birds are built differently. The bones of divers such as Common Loons are denser than those of songbirds and other expert fliers. With a lightweight skeleton, they’d be too buoyant to dive and chase fish. Instead, loons can kick their powerful legs and webbed feet to swim 200 feet or more underwater!
