This beach is in front of the cabin so there's not much to find. Very little human activity there aside from my family. Mainly used it to find the boat anchor and chain since it would always get covered in sand. Found a Bic lighter once! Still worked.
I think the seagulls get confused and associate shiny with minnows, thinking it's food. They're scavengers so they'll test everything.
Ah ok, well a Bic lighter is still a cool find 😁
Minnows - yes that makes sense, probably also why so many of them end up getting fish hooks in their beaks.
