There's tons more on the subject, I've looked into it- - Don't argue with me on this. Sure there isn't mcuh now. But imagine, they migrate, mate, and adapt (By growing more rapidley would be nice) this could pose a serious problem.
Meh.

They said its wingspan was between 15 and 20 feet. One of the teachers commented that it glided through the air on huge, bony wings - like a bat's.
September, 1982, Los Fresnos, Texas - An ambulance driver named James Thompson was stopped while driving on Highway 100 by his sighting of a "large birdlike object" flying low over the area. He described it as black or grayish with a rough texture, but no feathers. It had a five- to six-foot wingspan, a hump on the back of its head, and almost no neck at all. After consulting some books to identify the creature, he decided it most looked like a pterosaur.
