Near Round Knob, a deer carcass in a tree, fresh tracks and a dark-road sighting have neighbors talking about a cougar. None of those reports has been identified as a mountain lion.
Kay Comer posted the account, and 100.9 The Eagle published it on November 15. The signs sit in the woods around a small southern Illinois community. They are eyewitness reports, not a wildlife confirmation.
What Neighbors Say They Saw
Comer said a neighbor found a deer carcass hanging in a tree on his property. She said it was found Wednesday and, by Friday, had been moved and was mostly eaten. She also said that neighbor had been seeing fresh tracks and other signs around the property daily since the previous Wednesday.
Driving home in the dark, Comer thought a young cougar ran across the road in front of her. That is her reading of a brief nighttime glimpse. Nothing in the reporting independently confirms the animal, the tracks or what, if anything, put the deer in the tree.
The calendar dates behind those Wednesdays and that Friday are not pinned down, and the signs are described only as near Round Knob. A carcass in a tree is a striking scene. It is not, by itself, a species identification.
A Confirmed Cat, Then Remains
Southern Illinois did have a verified mountain lion this year, in a separate case. The Illinois Department of Natural Resources confirmed that a large cat spotted multiple times in Union and Jackson counties during August and September was a mountain lion, WFIW Radio reported on October 15. State wildlife officials believed those sightings involved the same animal.
That confirmation was described as the 12th verified mountain lion in Illinois since 2002, and the first confirmed sighting since one was documented in Pike County in 2025. Lone animals do cross southern Illinois on occasion. A run of county sightings is still a long way from a cat living in the woods outside Round Knob.
A hunter later found the remains of a young male mountain lion in Jackson County, near the Union County line, and notified conservation police, WPSD Local 6 reported. Conservation police were investigating the death. Foul play was not immediately suspected. The Round Knob reports are not tied to that animal.
Pass-Throughs, Not a Population
The Eagle, citing IDNR, reported that mountain lions do not have native habitat in Illinois. Wildlife Illinois is more specific on the population question: there is no evidence that resident breeding populations exist in the state, even though individual animals have been confirmed moving through.
Illinois Extension describes the usual traveler. Young male mountain lions wander large distances looking for a forested territory of their own. Southern Illinois has the most contiguous forest in the state, Extension says, and still could not support many mountain lions.
That is the practical limit behind the occasional headline. Forest cover can carry a dispersing cat for a while. It does not, on the evidence wildlife agencies publish, amount to a breeding population setting up house.
A Tree Is Not a Verdict
A hanging deer carcass invites a cougar story because people have seen that image before and filled in the author. Near Ashland, Nebraska, a Facebook post of what appeared to be a deer carcass hanging from a tree left people puzzled about the cause, the Star-Herald reported. Speculation is not the same thing as a track identified by a biologist.
Around Round Knob, the useful distinction is the same one the confirmed Union and Jackson case already drew. A large cat becomes a mountain lion in the record when wildlife officials say so. Until someone makes that call about these tracks, this carcass or the animal Comer thought she saw, the neighbors have a set of signs and a question, not a confirmed cougar.
