Rocky’s calm body language showing me it is ok to move in for a head scratch

One of the hardest things I hear and observe animals owners and caretakers struggling with is identifying and using reinforcers. Reinforcers are all around us all day. It is the individual that decides their reinforcer. A reinforcer is something delivered after a behavior that causes the future rate of that behavior to maintain or increase. Reinforcers can change in a matter of seconds and believe it or not, so many reinforcers are not food or treats.

Identifying reinforcers or building a list of reinforcers can be more challenging with shelter animals or animals that have lost or continue to lose their homes. Here at The Animal Behavior Center, you cannot rely on food reinforcers alone, they run out or satiate too quickly and the environment changes rapidly around here with the different animals, people, and behavior histories.
Following is a video I took this afternoon using the opportunity for me to pet with Rocky, the moluccan cockatoo as a reinforcer. Rocky was a shelter animal and came to me with a small list of reinforcers for me to work with. I had to build that list of reinforcers. The behavior I want to see maintain or increase in this video is for Rocky to remain on the perch while I rearrange perches and toy placement in the cage. Another important note is that Rocky is in Rico’s (another bird that resides here) cage in this video as a way to change environments and increase enrichment and learning opportunity. Rocky has a very strong history of showing aggressive behaviors such as lunging, chasing, hissing, charging the cage bars, biting, and biting very hard and doing some serious damage to the one he bites. Because he is in a different environment (Rico’s cage) in this video I cannot assume he will show predictable behaviors as he does in his cage. This is why you see me petting the top of his head and keeping my fingers away from his beak. I don’t want to accidentally reinforce a bite. I move my hands toward a toy to rearrange and then reinforce him by petting him when he remains on the perch. You will then see me get down off of the ladder and move to another area of the cage to move a toy. You will hear me bridge or mark the desired behavior with the word ‘Good’ letting Rocky know ‘that’ particular behavior is the one that is earning him the reinforcer soon to be delivered, which is me petting him.
You will also see that I have ‘can I pet?’ on cue. I don’t just move in to pet him, I want to give him clear indication of what I am asking. When Rocky wants someone to pet him he puts his foot up to the underside of his beak and begins petting himself.
We’ve come so far with so many behavior issues with Rocky from the aggressive behaviors I listed above, him learning to land so we could increase his flying time, his learning to forage, severely decreasing his screaming and abnormal repetitive behaviors, his separation anxiety, and most of all we are now on his second year of him letting people other than me pick him up and interact with him. He now lets anyone pick him up and is eager to do so.
