A Little Bird Told Me.
In the opening scene of Sergio Leone's, “Once Upon A Time In The West,” notice the bird in a cage. It's a green-yellow bird, a wild desert bird, and not a canary. Nobody cannot notice the bird in the cage, as it is thrust in the camera's lens by the director and, therefore, into the viewer's face. It's a "tell," or gamblers' slang, for a reveal. Sergio Leone is revealing to the viewer he is a gambling casino insider. A player. Without bragging, he is letting those also in-the-know, know he's been inside “the cage.” In Las Vegas (as any player can tell you), “the cage” is the casino bank tellers' window. Every player has been TO the cage. The director has been IN the cage. As even anyone who has never been in a casino can imagine, the cage has bars. It's a danger zone.
