Their webbed feet work like propellers, enhancing swimming efficiency and allowing agile turns during dives.

So while they might seem clumsy on terra firma, in water, they’re Olympic-level athletes, proving that appearances can indeed be quite deceiving.

Habitat and Migration

You might think loons spend their days in vacation spots, given their penchant for crystal-clear lakes in the northern forests and sandy shores during winter.

These birds are great world travelers, flying impressive distances from their summer homes in North America to cozy winter getaways on both the Atlantic and Pacific coasts.

Breeding Grounds and Locations

If you’re lucky enough to visit the northern reaches of North America, you might spot the iconic common loon gliding across crystal-clear lakes. These birds thrive in the pristine wilderness, nesting on secluded islands and shorelines.

Their breeding grounds stretch from Alaska to the Great Lakes region, providing:

• Shallow waters for foraging and shelter
• Deep waters for diving and social interactions
• Nearby forests for cover from predators
• Undisturbed islands for safe nesting sites
• Abundant populations of small fish to feed their young

Wintering Grounds and Locations
