A young Barbary macaque having fun with observing how my zoom lens moved in and out and the shutters opened and closed. He was really fascinated and demonstrated various facial expressions in the process, fom curious, interested, fascinated, mischievous, to cheerful, and eventually also bored. *g* But he "sat" for me (or I for him?) for about fifteen minutes, so he's forgiven for eventually being bored by yet another tall two-legger. It was also one of the most fascinating photography sessions I ever had with an animal.
