I know all of this because I have had trail cameras in that spot for years. Last year, I started getting worried because my rate of mountain lion sightings had gone way down. I'd gotten no mountain lion photos at that site in about a year. I worried that the lion population had plummeted for some reason.
This was a photo of a mountain lion in that clearing.
Then, one day as I rode my mountain bike through the woods, a cylindrical object on the forest floor caught my eye. I stopped, thinking that it was trash that I should pick up. After I examined it, I saw that it was an electronic device made by a wildlife company. I also saw tooth marks in the neoprene sleeve covering it.
I brought it home and Googled it. To my surprise, it was a light-sensitive device that made animal calling noises when it was dark outside. My reading told me that it was frequently used by photographers to entice wildlife to visit their cameras.
Then, I found a series of videos on one of the trail cams on that saddle. It was a mountain lion who was intrigued by the device.
I thought that it was cool to get to see so much behavior by the mountain lion as he checked out the device and eventually took it away! The funny part, to me, is that theft by a mountain lion is probably why the device was lying on the forest floor to start with (remember that I said it had teeth marks on it?). Now, the device is floating around in the forest again...
Enjoy the video!
