In June of 1840, three sailors hailing from the Scottish island of St. Kilda landed on the craggy ledges of a nearby seastack, known as Stac-an-Armin. As they climbed up the rock, they spotted a peculiar bird that stood head and shoulders above the puffins and gulls and other seabirds.
...
The sailors watched as the bird, a Great Auk, waddled clumsily along. Agile in the water, the unusual creature was defenseless against humans on land, and its ineptitude made it an easy target Prophet-like that lone one stood, one of the men later said of the encounter.
Perhaps the men enjoyed the thrill of the hunt, or perhaps they realized its meat and feathers were incredibly valuable. In any case, they abducted the bird, tying its legs together and taking it back to their ship. For three days, the sailors kept the Great Auk alive, but on the fourth, during a terrible storm, the sailors grew fearful and superstitious. Condemning it as a maelstrom-conjuring witch, they stoned it to death.
It was the last of its kind to ever be seen on the British Isles. Four years later, the Great Auk vanished from the world entirely when fishermen hunted down the last pair on the shores of Eldey Island, off the coast of Iceland. The men spotted the mates in the distance and attacked, catching and killing the birds as they fled for safety. The female had been incubating an egg, but in the race to catch the adults, one of the fishermen crushed it with his boot, stamping out the species for good.
