Mountain lions tend to sleep all day. Then, they wake up just before it gets dark to get to work either hunting or eating a cached kill. This guy came through around sunset so he was probably just waking up from his daytime sleep. When he arrived in front of my cam, he started by sniffing the scrape left by a previous mountain lion visitor.
When he raised his head, I saw his whitish chest, which is not common around here. The male who mated with a female lion nearby had a similar white chest. I suspect that this cat is the father of the mountain lion kittens who we saw not too long ago. Males play no role in raising kittens, and they will even kill the mother or kittens if given the chance. Surprising but true.
He became more interested in the scents, and he showed the Flehman response, opening his mouth so that he could redirect some of the scent molecules to his vomeronasal organ. It essentially lets him "taste" the scent.
After sniffing around at that site, he made a beeline for the next area where mountain lions mark. He sniffed and decided not to mark there. He breathed so loudly as he passed the cam that it is audible on the video!
His belly was very full, suggesting that he'd been eating all night long. He was probably heading to his day bed to sleep the day away.
I made a short video of this male mountain lion in daylight. What a treat it is to see his fur in full light!!!! (As an aside, I'm leaving my cams on Daylight Savings Time all year... so don't be confused when they seem to say that it was still light here at 6 PM!)
