Panda Man, I'm a little uncomfortable with the words, "witnessed the arrival". I'm leaning more toward words along the lines of, "has reason to be concerned about the possibility that the infamous creatures may have infiltrated the woods in the quiet suburbs North of Boston, turning previously safe backyards into treacherous and foreboding nightmares once darkness befalls neighborhoods once known only for giving our great Trick-Or-Treat candy." Also, I'd rather not use my name (in case the Chupacabras have any knowledge of names). Instead, I might like to be called, "Night Yeller".
I can't believe you actually wrote that. Very good. It occurs to me that the multiple flappings heard by Night Yeller could indicate that the Chupacabras may travel in families or packs. Imagine a few of them flying from a yard to the roof of the house and then away. Night-vision cameras may be a good idea.
OMG - that night vision picture is disturbing. I hope nobody discovers hidden nests of eggs deep in some South American jungle, indicating that the creatures appear to be multiplying far faster than in the past; and hinting at a genetic mutation. (Just saying what I hope doesn't happen. )
