Yellow-billed Loon

Gavia adamsii

Also known as White-billed Diver

Yellow-billed Loons navigate remote Arctic tundra lakes during summer breeding, giving voice to haunting wails and yodels that carry across open water. They are powerful foot-propelled divers, plunging deep to hunt fish before migrating south along coastal Pacific and Atlantic waterways for winter. Low reproductive rates and specialized breeding needs make them particularly susceptible to environmental changes across northern high latitudes.

Why interaction risk is low
Capable of delivering a sharp peck with its massive bill if cornered; keep a respectful distance.
What to notice
Recognized as the largest loon by its thick straw-yellow bill held at a slightly uptilted angle and bold checkered back in summer.
Support conservation
Observe from a distance using spotting scopes, avoiding approaches near Arctic nesting sites or wintering shorelines.
Responsible observation
  • Binocular Distance: Scan sheltered coastal bays during winter to catch sight of these deep divers without disturbing them.
  • Breeding Caution: Give nesting tundra lakes a wide berth, as disturbed parents may leave eggs vulnerable to cold and predators.
