You yell at the bird, pick it up from the couch, put it in its cage, and cover the cage with a sheet. This is Punishment . It is not directly associated with the action. In addition, the bird has no control, it can't stop chewing on the table to avoid the Punishment . Punishment should be avoided when working with most animals, especially birds.
Animals live in the here and now.
A Cue is an important part of our communication with an animal. It is a sound or an action that tells the animal what we want it to do. Telling a dog to sit, or directing it with the motion of your arm are cues . Moving our gloved hand toward a hawk on a perch is a cue that we want the bird to step onto the hand. We once had a Harris Hawk that would move from one perch to another anytime we waved a hand.
