I didn’t spend a lot of time beach fossicking during last week’s visit to Weymouth but, when I was walking along the front towards Lodmoor one morning, I noticed a man kicking at something on the sand. My curiosity got the better of me so, when the man had walked on, I went down for a look. This is what I saw.

It looked like a very strange snake but was, in fact, a piece of thick rope covered in possibly hundreds of Goose barnacles (Lepas anatifera), something I’d never seen before in person but had seen in photos on social media. The Wildlife Trusts website provided the following information:

Barnacles are a type of crustacean, related to crabs and lobsters. Goose barnacles filter feed on plankton and detritus, capturing it from the water with their specially adapted legs. In many places in the world they are a delicacy – in fact, in days gone by, any ships arriving in Cornwall with goose barnacles on the hull were a real moneyspinner. The goose barnacles would be scraped from the hull and sold for food.

These Goose barnacles didn’t look the least bit appetising to me. There was no way to know how long they had been lying on the beach and I wasn’t even sure if they were alive or dead, but it was certainly interesting to finally see these creatures.

From Goose barnacle to Barnacle goose?

Who could possibly believe that the Barnacle goose (Branta leucopsis) originated from driftwood? That was the ancient legend, that these geese were produced from the timber of fir trees that had been tossed about in the sea. The barnacle molluscs that can frequently be seen hanging from ships’ hulls were believed to be the birds’ ‘eggs’ and were named after the geese. This may seem crazy nowadays but the legend explained why these geese disappeared for months every year and were never seen breeding. The truth, of course, is that Barnacle geese usually migrate to foreign breeding grounds but our medieval ancestors weren’t to know that.

Barnacle geese from the Arctic tundra over-winter in the north and west of Britain in huge numbers, with as many as 40,000 birds from Svalbard in Norway flocking to the Solway Firth and equally large numbers overwintering in the Scottish Hebrides and in Ireland. The geese in my photographs, however, live permanently at Roath Park Lake in Cardiff. They are friendly little birds and are happy to approach humans, pleading for food by making a noise that sounds a bit like a dog barking, though they are happiest eating leaves, roots and seeds.
