As long as pigeons are going to deface the priceless structures and statues of Venice, they might as well be beautified as they do it during the Venice Architecture Biennale. That seems to be the thinking behind Julius von Bismarck and Julian Charriere’s latest art project. Around 60 birds were lured into a contraption that spray-painted their drab-gray feathers various tropical colors, in effect making them over into much less objectionable parakeets and parrots. They were then photographed for an exhibition of photos, Pigeon Safari, and released back into the urban jungle. The harmless food dye lasts around six weeks, the biennale until November 25.
