The last great auk in the British Isles was killed because its keepers feared it might be a witch. In 1840 five men discovered it asleep on the Scottish island of Stac an Armin. From John Alexander Harvie-Brown’s Vertebrate Fauna of the Outer Hebrides (1888):
It was Malcolm M’Donald who actually laid hold of the bird, and held it by the neck with his two hands, till others came up and tied its legs. It used to make a great noise, like that made by a gannet, but much louder, when shutting its mouth. It opened its mouth when any one came near it. It nearly cut the rope with its bill. A storm arose, and that, together with the size of the bird and the noise it made, caused them to think it was a witch. It was killed on the third day after it was caught, and M’Kinnon declares they were beating it for an hour with two large stones before it was dead: he was the most frightened of all the men, and advised the killing of it.
They threw the body behind the hut and left it there.
When the last heath hen, “Booming Ben,” died in 1932 on Martha’s Vineyard, local newspaper editor Henry Beetle Hough wrote an obituary for the species: “There is a void in the April dawn, there is an expectancy unanswered … We are looking upon the utmost finality which can be written, glimpsing the darkness which will not know another ray of light. We are in touch with the reality of extinction.”
