I’m going to assume this is about the woodcock, which does… This:
Science has a couple guesses which include:
- It’s a decent way to impersonate foliage blowing around in the wind for camoflage
- So other woodcocks can find them
- Carnivores look at that and go “That can’t possibly be food”
- Part of thier brains is literally upside-down, who the fuck KNOWS what’s going on in there.
My personal theory is that all woodcocks have a song stuck in thier heads at all times and The Just Gotta Dance.
It makes them even more lovable.
Chameleons and walking sticks do kind of a front-to-back version of that same walk, and they do it to pretend they’re foliage.
I’d imagine it’s probably some combination of all of the above, really.
