I know this is not the sharpest pic. However, it still makes me laugh.

I was about an inch away from this guy and of course I was zoomed in to where his head was (see prior shot - which is why his face is blurry).

However, I was surprised to see him flip his head completely upside down without moving anything but his arms.

His head pulled into the blurred area of my camera, but you get the idea if you realize his head is upside down.

Two seconds later, he flew off, but grazed my head to let me know who was boss.LOL
