Thats probably the most likely explanation for a deer attacking a tree for seemingly no reason, and messy chunks of flesh getting everywhere… but yeah, the standing on two legs thing…
… not strictly impossible, but… rather unlikely?
Deer can rear up on their hind legs, but I can’t say I’ve ever heard of one that can actually… locomote, ambulate, walk in that manner.
Ah yes, I heard about that one when I was a kid, forgot to mention it!
Damn headless chicken stayed alive for weeks… months I think?
It would walk around attempting to peck at things with a head it didn’t have… they used a little dropper to squirt some mushed up food … directly into its throat…
…and it actually died because one day it choked during this kind of feeding session, concievably it could have lived longer had that not happened.
Or at least thats the ‘death account’ I remeber my grandpa telling me, apparently there are multiple stories as to what exactly cause Mike to pass on.
