Daily body mass regulation in dominance-structured coal

Coal tits initially experienced the delivery of standard rewards (0.16 g; 4 units of food) preceded by 8 s of a light near to the center key, with an intertrial interval (ITI) of 262 s. They were then gradually shifted to an operant schedule where rewards were delivered conditional on key pecking at the central key. In each trial the light near the center key was on for 8 s, and pecking would
