One can insist that a cryptid is just a wishful manifestation of myth or folklore, but consider this:
If a cryptid exists and has been encountered by mankind, then it must also exist in folklore.
I was up last week camping on Hood Canal. I watched a raven come into the area, he seemed to come in just to antagonize the crows. The chase was on, I've watched this many times. Check this video out on crow intelligence
We aren't talking about dumb animals. They know their home ranges like the back of their hands, They would notice a typically mounted game camera as quick as you would if someone put one on a fence post or tree in your own yard. (And if a game camera is put up within a mile of their bedding area, one of the clan would likely watch you do it. Been there, done that. Last time was July 27, 2010.)
