Mothman?

I watched 'The Mothman Prophecies' at the weekend, and I had forgotten what it was about, but I enjoyed it alot more second time around, and it certainly got me thinking and wanting to look into the apparently true story of the mysterious 'mothman'.
While looking for more information I came across alot of similar bird men type things that have been reported all over the world, seems kind of weird and I think there has to be something in it.
The mothman that the film is based on is one from West Virginia, it was reported in a town called Point Pleasant for afew months before the collapse of the silver brigde. It is thought this 'mothman' figure appears before a major tradgedy, the appearances are often accompanied by strange dreams and frightening phone calls to people in the local area.
these are some drawings done by witnesses, showing what they saw, the figure is described as being around 8 foot tall





Other similar reports come from a Village in Cornwall, this time described as an owl man, this drawing was done by a young girl who supposedly saw this creature hovering around a church tower



we find another similar story known as The Black Bird of Chernobyl.
Menacing phone calls and terrifying dreams began mid April 1986 and contuinued untill the bird was last seen flying away from the smoke after the nuclear disaster at the end of April, workers described it as "a large, dark, headless man with gigantic wings and fiery eyes."



Could 'spring heeled Jack' of Victorian London be derived from the same strange entitiy? But just twisted to fit into a Penny Dreadful



These creatures are all terrifyingly similar, I think there could be something in it
