Early one morning, I captured a photo of a collared mountain lion in typical territory for these felines. She was alone. I'm assuming this lion was a female because she wasn't leaving scrapes and she's not big or muscular as an adult male lion.
Then, about a mile away, I captured a photo of another collared mountain lion, who I presumed was the same one as from earlier that morning.
This new lion became interested in the scent where the collared lion had rolled earlier that morning.
