Understanding Why Parrots Do What They Do ... Training your Parrot ... Resolving Behavioral Problems ... Foraging
Behavior problems exhibited by exotic pets are frequently the impetus for caregivers to seek help from veterinary professionals. One barrier to helping caregivers resolve these problems is the commonly held view that behavior is something an animal has rather than something it does, given certain conditions. By identifying and changing the conditions in which problem behaviors occur, these inappropriate behaviors can be replaced with appropriate behaviors, and caregivers and pets will experience more success living together. Functional assessment is a set of procedures used to identify the functionally related environmental conditions that maintain problem behaviors. These procedures have been well validated within the field of applied behavior analysis, particularly with children exhibiting severe behavioral problems. Functional assessment appears to have wide applicability to pets and other animals in captivity as well. The outcome of a good functional assessment is a summary statement that includes: 1) a clear, observable description of the problem behavior; 2) the general and immediate environmental conditions that predict the behavior; and 3) the purpose the behavior serves for the animal (e.g., the consequences the behavior produces). With this information, environmental changes can be made to make the problem behavior irrelevant, inefficient, and ineffective. Without this information, the wrong behavior may inadvertently be reinforced. At the same time, alternate behaviors that are acceptable to the caregivers can be reinforced to meet the same, or different, functions for the animal. A framework for accomplishing a functional assessment and systematic intervention planning is presented.
I once had a psychology professor who started every class shaking his head chanting, “Behavior is nothing if not complex.” Truer words were never spoken, and when it comes to the complex behavior of our companion parrots, we definitely have our hands full. With the potential for feather plucking, picking, shredding, and clipping … incessant screaming, screeching, calling and shrieking … not to mention biting, nipping, gnawing and clawing ? I’m never quite sure who to turn to for help, Dr. Skinner or Dr. Seuss! Reducing problem behaviors seems especially complicated. I have this image in mind of the desk toy with silver balls hanging from strings attached to a wooden frame. The moment you pull back one of the balls and release it, the others are set in motion and continue clicking against one another for a long time before they finally come to rest. Like this toy, behavior sets in motion a cascade of perpetual interactions so that analyzing any one behavior in isolation is essentially meaningless. Behavior is part of an endless reciprocal interaction among an individual’s genetics, behavioral history and the environmental context in which the behavior is performed.
In the face of such complexity, no wonder we all have moments where we feel overwhelmed and empty-handed when working with our parrots. To improve our ability to understand and influence our parrots’ behavior, we need a systematic approach which provides an organized framework and simplifies the seeming complexity that threatens to obscure our view.
As Simple as ABC
One such approach to understanding specific behaviors is known as ABC analysis. The letters stand for the three elements of a simplified behavioral “equation” which includes the antecedents, behavior, and consequences. With this strategy, we seek to identify through careful observation the events and conditions that occur before the target behavior ? antecedents, as well as identifying the results that follow the behavior - consequences. This simple analysis, when paired with keen observation skills and creative problem-solving, will help us clarify the way in which the basic components of behavior are interrelated. It is this clarity that leads us to important insights and teaching strategies.
There are six steps to analyzing the ABCs:
- describe the target behavior in clear, observable terms;
- describe the antecedent events that occur and conditions that exist immediately before the behavior happens;
- describe the consequences that immediately follow the behavior;
- examine the antecedents, the behavior and the consequence in sequence;
- devise new antecedents and/or consequences to teach new behaviors or change existing ones;
- evaluate the outcome.
Let’s look at one example:
Veda, my otherwise charming Alexandrine Parakeet, Psittacula eupatria, bites fast and forcefully when I ask her to step onto my hand from inside her cage. Seeing the problem in isolation and decked-out in its full complexity, we might hypothesize that she is aggressive, territorial, hormonal, defensive, or dominating. Alternatively, she could be recalcitrant, stubborn, uncooperative or simply a stinker who is also spoiled rotten! Any one, or all, of these hypotheses might be accurate, but in terms of problem-solving, they serve only to label the behavior, not resolve it. And, since they do not describe observable behaviors per se, one can never really be sure about the accuracy of the label.
The ABC Analysis
What follows is my analysis of Veda’s biting behavior using the ABC approach:
First, the background and setting: When asked to step onto my hand from inside her cage,
Veda often, but not always, bites me! She does not bite under any other circumstance or
in any other situation. She does it any time of day and with all her family members.
However, once out of her cage, Veda steps up and down without hesitation, from all
locations, including the top of her cage. For three or four hours each day, Veda plays
happily on her tree perch in the family room, enjoys cuddles, and generally relaxes by
preening, playing with toys and nibbling. She is by all other measures an outstanding
Step 1: Describe the behavior in observable terms.
Veda widens her eyes, tightens her grip on her perch, pulls her body back and waits in
this position for a second or two. If I don’t move my hand she bites it hard.
Step 2: Describe the antecedents.
Any time I walk up to Veda’s cage, I greet her to let her know I’m there. I open her cage
door, slowly put my hand in front of her and say, “Step up, Veda.”
Step 3: Describe the consequences.
I remove my bitten hand (hurt and annoyed), and Veda stays in her cage. Case, or should
I say door, closed.
Step 4: Examine the antecedents, the behavior, and the consequences in sequence.
Any time I walk up to Veda’s cage, I greet her to let her know I’m there; I open her cage door, slowly put my hand in front of her and say, “Step up, Veda.” Veda widens her eyes, tightens her grip on her perch, pulls her body back and waits in this position for a second or two. If I don’t move my hand, she bites it hard. I remove my bitten hand (hurt and annoyed), and Veda stays in her cage.
Let’s stop here for a minute to examine the insights that resulted from this analysis, as it helped me clarify several important things. First, far from being a biter or having a biting problem in any chronic or generalized sense, I learned that Veda displays a very specific set of responses, in a specific location with a different antecedent than I had originally assumed. Before analyzing the ABCs of Veda’s biting behavior, I had not realized that she tenses her body, pulls away from her perch and widens her eyes in a valiant attempt to warn me to withdraw. How remarkable!
In this light, it becomes so clear that the critical antecedent to her biting is not my putting my hand in her cage; it’s ignoring her non-aggressive communication, requesting me to remove it. Only when I ignore her communication and persist does she resort to biting.
So, who set the silver balls in motion this time, Veda or me?
It is also evident that by withdrawing my hand and leaving her in her cage, I was in fact, reinforcing the biting. With each of these interactions, I was unwittingly, but explicitly, teaching Veda that biting is an effective and necessary way to get my hand out of her cage; apparently so, since warning me non-aggressively did not work. I’m sure she would say it was nothing personal but that I was quite … dense! Can’t you just hear her explaining this to our baby cockatoo? “Listen up, baby. No matter how kind and gentle you want to be, these humans respond to one thing and one thing only, aggression. Why, it’s a jungle in here!”
Step 5: Devise new antecedents and/or consequences.
After careful consideration of my options, in this case I chose to change the antecedents to decrease Veda’s biting. First, I no longer say, “Step up!” when I want her to come out of her cage. Instead I ask her, “Wanna step up?” If she displays the warning behaviors, I take that as an unqualified “No, but thanks for asking!” and I calmly remove my hand from her cage. I then leave her cage door open, allowing her to exit how and when she chooses. As an additional strategy, I trained her to step onto a perching stick for those rare times when staying in her cage is not an option. We practice stepping onto the stick a few times a week, for which she earns an avalanche of praise and kisses.
Step 6: Evaluate the outcome.
Changing the antecedents to decrease Veda’s biting has been a huge success. Of course it is not surprising that she no longer bites me – by heeding her warnings, I don’t give her the opportunity, or the reason, to do so. I continue to present my hand to her and ask if she wants to step up. If she tenses her stance, pulls away and/or widens her eyes I remove my hand and go on to other things (you know, like cleaning cages and changing water bowls, uh-huh).
What has been very unexpected is that after a few months of letting her decide how to come out of her cage, she now rarely declines my offer to take her out on my hand, choosing instead to step up nicely and hitch a ride! Who knows … maybe the freedom of choice was important to her or she benefited from more control over her own destiny; perhaps her trust level increased when I lowered my apparent dominance. These are all very interesting possibilities.
In my opinion, we generally focus too much on consequences to influence behavior. This is especially true of negative behaviors that we want to decrease or eliminate. In this way, we limit ourselves to rewarding or punishing more or less. One of the exciting benefits of this simple analysis strategy is that it fosters careful consideration of the antecedents, that is, the things we do to promote … or provoke … behavior. Antecedents should be brilliantly arranged to ensure that the appropriate behavior is facilitated. Doing so makes selecting consequences easy – when the behaviors are all acceptable, the consequences are all positive! I truly believe (and my experience working children bears this out) behind every negative behavior is a poorly arranged antecedent. Some of you may have other insights to add to my analysis or other solutions to suggest.
There is certainly more than one way to productively analyze a behavior sequence and more than one useful solution to be devised. The right analysis and solution is the one that produces the desired outcome, fits the style in which you and your bird are comfortable interacting and improves your relationship with your bird. With Veda, all three criteria were met. In our teaching, we are limited only by our powers of observation, our creativity and our resolve to treat our parrots humanely and with compassion.
Of course, behavior is not always as linear as it appears when analyzing the ABCs; but I think the more important insight is that none of us, including our remarkable parrots, behaves in isolation from the events around us. Although analyzing behavior can sometimes be like walking into the hall of mirrors at an amusement park, other times behavior is very straightforward. It is at those times that a simplified approach to analyzing behavior is just what we need to increase our understanding and develop better teaching strategies. I have found analyzing the ABCs of parrot behavior to be very useful for clarifying the related components of many, many different types of behavior. Once these relationships are clear, the path to creative, positive solutions and teaching plans become more clear as well. I hope you will try analyzing the ABCs and find doing so a helpful addition to your parrot mentor’s toolbox.
