ALIEN CREATURE SPOTTED IN MY BACK YARD ON 12-29-12

WHAT IS IN MY BUSHES?
Last night Dec 29, 2012 at 1:55 Am I started taking picture upon review this was in two of my pictures.
I have gone back out there four times and cannot figure where this image could have come from.
I thought maybe something behind the image but there is nothing there that would stand out like this.
Then I thought maybe it was a big leaf! But it would have to be a giant leaf which I have none.
What is this in my bushes?
Is it Spirit Or Alien?
I could use some help on this one!
