I posted this thread because I have no doubt that what people are seeing are mountain lions. THE real question is:
1. Is there a population living in the Pines?
2. Are they escapees from someone's personal zoo?
3. Are they transient and just moving through?
Although some would suggest that #1 above is highly unlikely, I don't think consideration is being given to the sheer size of uninhabited areas within the Pines. And with a substantial food source... I don't mean just deer; a family group “could” survive here. Therefore, a vestigial population (e.g. non-breeding) could roam about and coupled with the species’, instinct to avoid humans, they could certainly be here now, with sightings popping up every now and then. In addition to these sightings, a mountain lion was confirmed in the very nearby state of Delaware in 2002.
Wildlife Ecology is really not my field, nor am I receiving grants for this type of research, so if I were pressed for an answer to the question above, I could make an educated guess without any repercussion to my reputation or believability. So… my guess is that there is a small family group comprised of two or more individuals that is sometimes transient and sometimes hunkered down in the area for one or more years. This of course raises another question. Are they escaped from captivity or have they been moving in from the Western states over the years? Both theories can be proven or disproven, so take your pick.
