Boldly patterned in black, white, and silver, Barnacle Geese are stunning birds. In Europe, huge flocks gather in pastures and mudflats where the geese feast on grasses and moss — but not barnacles. So where did they get that name?

How the Barnacle Goose Was Named
Written by Ariana Remmel
This is BirdNote.
[Barnacle Goose]
Barnacle Geese are stunning birds. Their feathers are boldly patterned in black, white and silver. In Europe, huge flocks gather in pastures and mudflats where the geese feast on grasses and moss — but not barnacles.
So… where did they get that name? The answer harkens back to a medieval myth.
[Medieval music: Lux by La Reverdie]
Barnacle Geese have wintered in the British Isles for millenia. People from the Middle Ages observed that adult birds would turn up in autumn, then vanish come spring. Since locals never found them with goslings or eggs, they scoured land and sea for an explanation of how the geese reproduced.
What they found were barnacles — ones that have a large, white shell attached to a long, grey stalk. To early naturalists, these barnacles looked suspiciously like a bird egg growing from a goose neck. Putting two and two together, great minds deduced that the mysterious birds must hatch… from barnacles!

Modern science eventually debunked the myth that geese spontaneously generate from marine crustaceans — they migrate to the Arctic to breed — but the name stuck. So even today, Barnacle Geese tell a tale as old as medieval times.
