Drunken Squirrel:

 

 

We have a few blueberry bushes that are about 12' tall and some of the blueberries are fermenting on the bush. Squirrels love them. I saw a squirrel yesterday laying on a limb in a tree at the end of our deck and figured he might be a little drunk. We learned about this when camping in Torrea State Park in N. Fla several years ago. We were camped in an area with very tall pine trees and laying in my hammock I kept hearing this thump noise. All I would see was a squirrel on the ground.

I finally figured out what it was and watched this squirrel fall off a scuppernog grape vine that was high up in the trees. He was eating those scuppernog grapes that were fermented and then falling off the vine to the ground which was soft with 5-6" of pine needles. He would lay on the ground until he recovered and then go back for more. 

Apparently it is the same with blueberries.
