Something about this orangutan that always gets to me. I don't know if it's the lonely way she looks out through her cage or the clicking noise* she makes. I do wonder what she's thinking and if she's comfortable with her life. I know this photo was taken in the worst possible lighting but still, her eyes speak from those shadows (with a little brightening in Photoshop).
*She makes a noise that could be teeth grinding or something else. The zoo never seems to know where the noise comes from other than her.
