I founds this bin of eggs in the grocery store in Patreksfjörður, in the West Fjords. It was sitting on the ground just under the dairy refrigerator. Locals have been collecting and eating the eggs of Razorbills and Guillemots on these cliffs for nearly a millennium. Note the shape of the eggs with a very pointy conical shape, so they roll in circles on the cliffs, rather than risk rolling over the ledge into the ocean.

Having talked to a local biologist, I learned that while these birds may be at risk in other parts of the world, there are thousands of nesting pairs on these cliffs here, and the small amount of eggs collected seem to have no impact on the overall population.
