I had an encounter with a cougar recently. I was walking down a muddy old forest service road when approximately 15-20 meters behind me a deer burst out of the brush with a cougar chasing it close behind. The cougar gave up the chase on the deer but watched it jump away (instead of turning around to see what I was doing). Meanwhile I am backing away around the corner to get out of the situation. I didn't see either the cougar or the deer again.
What I'm curious about that a biology perspective might be able to answer is how frequently cougars return to a hunting area. My qualitative understanding is that they have very large ranges, so under a quite few stochastic process models I would expect them to return to the same hectare relatively infrequently. But I don't have a quantitative understanding of this.
A cougar was spotted by someone else approximately 15 kilometres away within 2 weeks of my encounter.
