Forehead of an endangered Siberian Tiger

I cropped this image, as there were metal bars that left blurry lines on both sides of this central part of a Siberian Tiger's forehead. Just seemed a shame to waste the photo of such an endangered animal. I need more time to look through my photos - but I also shouldn't be doing this, as my very painful arms should be resting away from the computer : ) Taken at the Calgary Zoo on 13 March 2010.
