The 'Great Auk' was a large, flightless seabird that went extinct in the mid-19th century. Imagine a penguin-like bird, but found in the North Atlantic, not the Antarctic. It was about 75-85 cm tall and well-adapted for swimming and diving in cold waters. The Great Auk was hunted to extinction for its meat, eggs, and feathers. Its disappearance is a tragic example of how human actions can drive a species to extinction.
