While reports of large winged-things in Britain are not as prevalent as in the US, they do exist. Without doubt the most famous one is the "Owlman" of Cornwall - a strange, ominous and glowing-eyed entity that haunted the woods around the old Mawnan Church in the mid-to-late 1970s.
But, now, there's another report of a Mothman-style beast from Britain, and here's The Anomalist to tell us more:
Mothman in Seaham on Sea? Hmmmmm Cryptozoology Online. Davey Curtis writes up a story told to him by a couple who experienced what may have been a Mothman-type being on the outskirts of Seaham, a city on the northeastern coast of England. Curtis believes the couple's tale and notes some of the synchronicity the late John Keel spoke of in his writings about the Mothman of Point Pleasant, WV, in the USA. Curtis notes the name of the place where the sighting took place and documents other things Keel mentioned seemed to attract such phenomena as Mothman: the couple's sighting was close to power lines, a military base and the "name Cold cropping up in ancient settlements". The sighting on the outskirts of Seaham occurred in a place called Cold Hesledon. Has synchronicity been reached during a Mothman encounter along England's northeastern coast? With images.
