But trainers also need to focus on even smaller behavior changes. A simple quick look with the eyes to one side may mean the bird is looking for an escape path and is ready to take off. Use as little or no negative reinforcement as possible. This sounds self-explanatory. However, many trainers do not take this to the highest level.
Birds can be relatively small non-threatening animals.
It is pretty easy to make a tethered hawk get onto your glove. However, a greater challenge is for the trainer to either use positive reinforcement or as little negative reinforcement as possible to get the hawk on the glove. This again requires the trainer to use excellent sensitivity to bird behavior skills. The steps to this could be for the trainer, from 20 ft back, observe the bird's behavior, read and interpret and react accordingly to help create a situation in which the bird is as comfortable as possible. This may mean crouching down.
