Interesting report. Black cat sightings along that corridor have been trickling in for years and nobody in any official capacity wants to touch them with a ten-foot pole.
For what it's worth, the Pacific Northwest has its own version of this problem - large felid sightings that get dismissed as ". Misidentified bobcats". By wildlife authorities who clearly couldn't find a bobcat on a good day with a GPS tracker. I've had my Bushnell trail cams out in remote areas and captured some genuinely puzzling prints that don't match anything supposedly native to the region.
The Blue Ridge sightings are particularly compelling because of the consistency in the descriptions - substantial black colouring, long tail, low-to-ground movement, deliberate rather than panicked behaviour. That last detail matters. Escaped exotic pets tend to behave erratically. What people are describing sounds like an established animal with established territory.
Worth noting: there are melanistic bobcats documented, but the size witnesses report consistently rules that out. We're talking something closer to mountain lion dimensions.
A few questions for anyone who saw it:
Approximate time of day?, Was the animal aware of you, or indifferent?, Any unusual smell in the area beforehand?
That last one sounds odd but predator musk is genuinely detectable and it's a detail fabricated witnesses almost never include. If you noticed it, that adds real credibility.
Anyone running camera traps along that stretch? If there's a consistent sighting cluster forming, that's exactly where you'd want equipment deployed now before the season changes and the animal shifts range.
