Great Auk

Great Auk

Pinguinus impennis

Extinct

Once a majestic symbol of the North Atlantic's rugged coasts, the Great Auk was a bird of striking contrast and remarkable endurance. With its jet-black back, gleaming white belly, and distinctive white patch between the eye and bill, it was an unforgettable sight on the rocky islands where it bred. Known for its deep, growling call and impressive diving abilities, the Great Auk was a remarkable presence in the ocean's icy waters. Today, it stands as a poignant reminder of the profound impact humans can have on the natural world.
