Bullion on Mullion?

The appearance of copious numbers of elastic bands on Mullion island off the coast of Cornwall confused scientists for some time (https://www.theguardian.com/environment/2019/oct/23/depressing-mystery-of-elastic-bands-found-on-remote-mullion-island-solved). It now appears that nesting gulls were picking up these items (often dropped by postal workers on the mainland) and bringing back these 'worms' to feed to their chicks. The practice suggests that food items are very much in short supply for these birds. The bands might well cause many problems for animals in this location.
