Children in the Wood

So I took this pic at our local duck pond, when I got home and downloaded them, I saw what appeared to be a child in the background behind the two girls on the right side. Is this a ghost or weird lighting and trees?

Note: blur effect added by me to protect underage identity.

I have to admit, this one startled me as I'm sure it did our photographer when it popped up on a computer monitor.  It appears to be the specter of a little child in a nightgown watching the kids at play.  It's almost a classic ghost image.

Alas, however, upon investigation I believe that the ghost child is merely plant material - possibly weeds or a tree trunk - illuminated by the flash of the camera.

Still, I love this picture even though I don't think there is anything paranormal happening.  The shock value of it is outstanding.
