Pigeons pecking a key on a fixed-ratio schedule pause after receiving a reinforcer. This interruption in operant responding is defined solely by the absence of the responding. The purpose of the present study was to find out what a pigeon does during the pause in key pecking, and whether non-pecking behavior is different across transitions between the rich and lean components of a multiple schedule. Using videos of four pigeons, the duration of several non-pecking behaviors was recorded during the pauses that occurred after the end of a reinforcer and the start of responding in the next component. The pigeons spent the most time looking away from the key, distancing from the key, and looking at the key. All pigeons only preened during lean-lean and rich-lean transitions. Select pigeons only side stepped and paced during the rich-lean and lean-lean transitions.
