Posted this in the local Reddit and got absolutely demolished, so I'm trying here where people might actually take it seriously. I've got a small cottage just outside Hebden Bridge on the edge of the moors, and every winter - and I mean every single winter without fail - I hear screaming in the early hours. Not human screaming. This sound is... wrong. Like an elk call mixed with a man's roar, if that makes sense.
It started about six years ago, always between October and March, always between 2am and 4am. It wakes my partner up too, so I'm not losing my mind. We've got decent wildlife knowledge - I'm pretty sure we can distinguish a fox from something else. This is something bigger. The sound carries for miles across the moors when the wind's right, and the local sheep absolutely freak out when it happens.
I've never seen anything, never found tracks. But the acoustic profile is consistent, and it's definitely not a known British mammal. The question is whether we've got something large and undocumented living in the Pennines, or whether this is misidentification of known animals. Keen to hear from anyone with similar experiences in upland areas during winter.
