Bird usually stretch the wing and the leg on the same side of the body at the same time. Several of them do this to salute their owners and begin a new task. Bonded parrots do this in union.
The parrot slaps its wings against its body. Baby parrots flip their wings against their bodies when asking for food. Adult parrots (mainly Quakers) are likely to do this to as a symbol of being need to food. If it is the case, the body will be flattened out. If the body is erect, it indicates that the parrot is disturbed, upset or frustrated. If this behaviour is combined with eye pinning and tail flaring, avoid touching the bird was it may have a certain allergy towards interaction.
