Scatology 101 (or who's poop is this?)

Join us on a stroll through Baker Meadow as we look for animal scat. That’s right! The biproduct of the animal’s waste. Find out how this discarded material is used by animals to communicate, protect from predators and the elements, and attract mates. We will dissect an owl pellet and determine what prey is consumed by owls. And how a coprolite (fossil scat) is used by scientists to reveal essential information about the diets and environments of ancient creatures, showcasing ecological interactions and changes over time.
