Leaf Face Ghost Picture

Derek Heeps sent us this ghost picture of what looks like a human face, side profile. What do you think?

"I am baffled by this picture I took whilst out walking my dog in Randalstown Forest, Country Antrim, Northern Ireland. I took it with a new digital camera on 3/12/08. A face of a man can clearly be seen in the upper left hand corner in the tree. I have zoomed in and cannot explain it by any other means. I would love to have your thoughts!"

Is it a leaf that simply appears to the human eye as being a face?  Read more about this effect known as pareidolia, or matrixing.  The second photograph shows the scale of the face in relationship to the tree branches.
