We had a patch of garden that was always boggy. I have romantic notions of there being a hidden lake or stream beneath that leads to a lost world, but it’s probably just a leaky water pipe. Anyway, as a bog, it was a bit dangerous, so we made it into a pond. For years, it has just been a rather uninteresting stagnant pool, but today, it underwent a refurbishment as a family of ducks moved in and cleaned it all up. Are they just visiting, or are they moving in permanently? Only time will tell.
