Been researching sightings around the Yorkshire Moors and notice something odd: there are clusters of "large unidentified animal" reports that seem to peak around the summer solstice period (June 19-21) and then again during the autumn equinox. I'm not talking about misidentified sheep or deer - I mean reports of something genuinely large, black or dark brown, moving with unusual gait or speed.
The earliest report I found was June 1987 (a hiker near Haworth saw what they described as "something like a big cat, but wrong somehow"). Most recent cluster was summer 2019 with three separate reports within two weeks. Local farmers have mentioned losing livestock during these periods, though they usually blame foxes.
Is there any documented pattern here, or am I pattern-matching where there isn't one? Cryptid enthusiasts might have better resources than I do. Would love to compile a proper database if others have sightings to contribute.
