For my continuing long term DNA study of our San Francisco coyotes, I needed some scat (DNA is taken from the scats) from a very specific newcomer male coyote about whose origins I had no clue. I already had scat from his mate — I had seen her defecate many times and afterwards collected it, but I just simply was not seeing the activity from the male. Picking up scat right after seeing it expelled is how I know which coyote the sample came from. I had seen old scat in certain locations several times, but of course I didn’t know WHO it came from.  My solution was to catch WHO that scat came from with an automatic wildlife field camera I put out at night. I ended up putting out two such cameras in the same location. I got what I wanted, and more!

When I went to retrieve the two cameras the next morning, I was disappointed to see that one of them was gone: it had been taken — stolen. I looked over to where the second camera had been placed and was relieved to find it still there — the thief had not seen that one. I wondered if maybe that camera would reveal who the thief was?
