The Great Auk: An Extinct Bird’s Story and Future

The great auk was a large, flightless seabird that inhabited the cold waters of the North Atlantic. Often called the “penguin of the north,” it stood out for its upright posture and distinctive black-and-white markings. This bird thrived for centuries, forming a significant part of the marine ecosystem. Its story is a compelling look into the relationship between humans and the natural world, showing how a once-abundant species can disappear completely. The great auk’s extinction has left a lasting mark on scientific and cultural memory.

Biology and Habitat

Standing 75 to 85 centimeters tall, the great auk had a black back and head, a white front, and a white patch of feathers before each eye. Its large, powerful bill was marked with several transverse grooves, which it used to catch fish. Its wings were too small for flight, measuring less than 15 centimeters. They were used as flippers, allowing the bird to “fly” underwater with agility.

The great auk was a powerful swimmer and diver, preying on fish like capelin and sand lance. Its habitat stretched across the North Atlantic, from the coasts of Canada and the northern United States to Greenland, Iceland, and the British Isles. For breeding, the bird required remote, rocky islands with sloping shorelines for easy ocean access. These isolated locations protected their single, large egg from predators.

Important breeding sites included Funk Island off Newfoundland and Eldey Island in Iceland. These colonies were densely populated, which concentrated the birds in predictable locations. The great auk’s closest living relative is the razorbill, a smaller seabird capable of flight. This genetic relationship has become a point of interest in modern science.

The Path to Extinction

For centuries, indigenous peoples of the North Atlantic hunted the great auk sustainably for food, oil, and bait. The bird’s flightlessness, lack of fear of humans, and dense, accessible colonies made it an easy target. After European fishermen and commercial hunters arrived in the 16th century, the exploitation rapidly escalated to an industrial scale.

Sailors slaughtered them by the thousands for meat to provision their ships and used their oily bodies for fuel. A trade also emerged for their feathers and down, which were highly valued for pillows and mattresses. Entire colonies were wiped out as hunters herded the defenseless birds onto ships or boiled them in large cauldrons to easily pluck their feathers. This pressure pushed the species from abundance to rarity.

By the early 19th century, the great auk was endangered, with only a few small populations remaining. The rarity of the bird increased its value to collectors and museums who desired skins and eggs as scientific specimens. The final act of its extinction is precisely documented. In June 1844, on the island of Eldey off Iceland, the last known breeding pair was killed by three sailors. One of the sailors then crushed the last-known egg with his boot.

Legacy and De-Extinction Efforts

The disappearance of the great auk became a symbol of human-caused extinction. It was one of the first extinctions widely recognized by the public and scientific community as being the direct result of human activity. This served as a cautionary tale in the burgeoning conservation movement. Today, around 80 skins and a similar number of eggs are all that remain, preserved in museum collections worldwide.

Advancements in genetic science have introduced the concept of de-extinction for the great auk. Scientists consider it a candidate because of available preserved DNA from museum specimens. The plan involves sequencing the great auk’s genome and comparing it to that of its closest living relative, the razorbill.

The process would be a form of genetic engineering, not traditional cloning. Scientists would edit the razorbill’s genome to include key great auk traits, creating a hybrid embryo. This embryo could then be implanted into a surrogate parent. While the technology is still developing and faces significant ethical and ecological questions, the discussion ensures the great auk’s story continues to influence scientific thought.
