first-contact cryptozoology

"While Mr Sporing was drawing on the Island he saw a most strange bird fly over his head; he describd it about as large as a kite and brown like one, his tail however was of so enormous a [length] that he at first took it for a flock of small birds flying after him. He who is a grave thinking man and is not at all given to telling wonderfull stories says he judg'd it to be at least yards in lengh."
