Mystery abounds in the North Campus, for who's been leaving scat under the footbridge? I discovered a vast array (about 10 pieces) of scat while I was searching for fungi a few weeks ago, and of course I snapped some pictures to try and identify our most recent visitor.
Who does this scat belong to?
My gut told me the scat belonged to either a Virginia Opossum, Didelphis virginiana, or a Raccoon, Procyon lotor. To get a definitive answer I did two things. Firstly, I sent this picture to Jim Dines, the Museum's Mammology Collections Manager. Secondly, I put Sam Easterson on the project to set up a camera trap.
Almost caught in the act!
The trap that Sam put up over the Thanksgiving Holiday recorded at least one, if not two Virginia Opossums under the bridge! Although, we didn't capture footage of an opossum in the act so to speak, I am pretty confident we've discovered our scat provider! In concurrence was Jim, "You're right that it's probably opossum. They can have such varied diet that their scat can be hard to identify."
On the subject of scat, I have one last thing to show you! Unlike the Virginia Opossum, the Burrowing Owl, Athene cunicularia, we saw last week was caught in the act!
Aside from an in-depth view of owl bowel evacuation, this footage shows how Burrowing Owls are adept at standing on one leg. This isn't a circus trick, it actually allows the bird to keep the other leg warm in the feathers and only allow precious warmth to be lost from one leg at a time!
