Negative reinforcement involves making a bird do something. Even though bird trainers have traditionally utilized negative reinforcement for some components of training, there is the potential for even greater success using positive reinforcement or reducing the level of negative reinforcement as much as possible. Understanding the theory behind the suggestions to help develop sensitivity to bird behavior is important. However, it can be difficult to conceptualize. Moving birds in crates is as smooth and steady as it can possibly be.
Birds leave a trainers hand or perch willingly to fly.
It is not necessary to launch a bird into flight. The bird has control and choice in the matter. Birds tails never touch or hit anything. Most birds do not like their tails to touch things. Birds fly or sit facing into the wind or in a crosswind.
