Pigeon courtship in the double closed-loop teleprompter apparatus. The double teleprompter interface allowed us to film the stimulus partner while they were interacting with a live conspecific. When these stimuli were played back in the teleprompter during the experiment, they contained socially motivated that was oriented directly toward the subject bird at the same position as the original partner. Here a male pigeon is seen interacting with a female partner on screen.
