When visiting Gibraltar, it is always a treat to see the various clans of apes (technically Barbary Macaques) running about the city and towering rock. Although they are, at times, a little too comfortable with human contact, this does allow for easy photo opportunities. This particular fellow is one of the older apes atop the rock and posed kindly for a stoic portrait.
