Who pooped?

Leave a comment below with your guess. We will reveal the answer on in the comments section on Tuesday, September 13th.

If you have your own natural history mystery (an unidentified animal, plant or other specimen), send a photo or two to naturalist@calacademy.org. We’ll do our best to help out. Please include location, date and any other details that seem pertinent.

  3. It is indeed replica deer droppings! It is the scat of Odocoileus virginianus, the Whitetail Deer.
