From Julian Charrière and Julius von Bismarck's "some pigeons are more equal than others" exhibit. - 

And finally, to one of the most beautiful cities in the world: Venice, Italy --  where everything is just spectacular. The canals, the bridges, the piazzas, the pigeons...

Well, actually the pigeons are kind of ugly, just like the pigeons everywhere else. So why not paint them different colors using non-toxic spray paint?

That's what two artists in Venice have done. See the work from Julian Charrière and Julius von Bismarck above, which ruffled some feathers at the Venice Biennale this year.
