The magician crumpled his hat and the bird was nowhere to be seen. "You crushed it!" Cried the boy. "No, you see" as he opened his coat and the bird flew out. "That's just a different bird that looks the same" protested the boy and his parents shushed him...

Later after the show, they boy returns and witnesses the magician dump a dead bird into the dumpster.

As zizek claims in his new book, progress is not magic. It is always relative to a system and always requires us to ignore dead birds.
