Fake looking photo..

I was at the zoo yesterday and I took a couple of shots of the Mandrills, this was one that I was quite pleased with until I got my card home and viewed the shot on a larger screen..

Can anyone tell me why the shot came out like this? All EXIF information should be there if that helps..
