This guy was quite the accommodating little chimp. He just sat in the window and smiled at me as I snapped away.
He was very interested in my lens and tried sticking a beady eye down it at one point. It's a shame the light was so bad because I've got a couple where his face just fills the shot but a slight blurring plus reflections off the glass make them unusable.
Edit : I should also add that this was taken at 1/25th sec. Just goes to show the virtues of image stabilisation!
