This is really as good as it gets short of convincing one to walk into a lab for a physical. We have many eye witness reports, even up close, but all lack physicality. This is as physical as it gets. I am impressed that it survived a 40 mile per hour impact at all. However a tough animal certainly can do just that. That it was able to shake of the shock and fly off is impressive.
This is our Mothman and it is certainly our gargoyle as well. It is also the primary source for cattle mutilations as well. The creature feeds on blood and occasional soft tissue. And yes, you want to be scared of it, although it knows well enough to be wary of us.
It is one more nocturnal predator in our curious inventory of nocturnal cryptids..
