Pigeons can perform impressive feats when trained with classical chaining, but these apparently sophisticated performances diminish in accuracy if the context changes or chained behavior is interrupted. Pigeons cannot easily start chaining in the middle of the sequence, omit steps, or modify the chained sequence to adapt to new conditions. We are studying the grey parrot's ability to transfer serial learning from an initial context to new contexts with minimal retraining, and to acquire knowledge beyond simple stimulus-response. While similar to classic operant-conditioning studies, here the parrot must demonstrate versatility in his behavior.
