I finally got around to cleaning off all the bird droppings on my deck. I learned a few things in doing so:

  • Over time, the piles of bird droppings form a histogram of where the birds like to perch.
  • Birds prefer hanging out on the rafter above the north end of my deck.
  • Individually, bird droppings don’t have much of a smell. En masse, they do. Here, en masse means about one and a half dustpans’ worth.

Now you know.
