I need help with my phobic parrot!

Friday, July 31st, 2009

You read it all the time in internet chat groups and even magazine articles, “I need urgent help with my phobic (insert parrots species).” It seems to me that the majority of people asking these questions and many of those answering them do not understand what phobia is.

Let’s start by going to Webster’s for a definition of phobia:

“Noun: an exaggerated usually inexplicable and illogical fear of a particular object, class of objects, or situation.”

I feel that it is highly unlikely that most so-called “phobic” birds have the above described type of fear. The key words here are “inexplicable” and “illogical.” The root cause of such behavior can usually be traced to the history of interactions with the owner or in the case of a rehomed bird, the previous owner(s). This is hardly “inexplicable” or “illogical”. A bird that displays aggressive behavior towards hands is probably a bird that has never been “listened to” when it clearly communicated that the hand approaching was not welcome. Through its body language a bird communicates it is either ready or not to accept an approaching hand. When the owner sees, understands, and respects this communication the bird gains a little more control over its environment and with control comes confidence.

In addition using “phobic” to describe the behavior of a bird is applying what is defined in psychology as a construct or label. Regardless of whether the condition is based upon an illogical or inexplicable fear the word “phobia” only attempts to ascribe a condition or state to the bird, it does nothing to describe what the bird actually does, or the conditions in which it does it. Remember, the smallest meaningful unit of analysis is behavior and conditions.

The first step in addressing behavioral problems is to accurately describe the behavior, what happens immediately before the behavior (the antecedent), and what immediately follows the behavior that is maintaining it (the consequence). This is what is called a functional analysis of the problem and I wrote about this process in an earlier article. That article and another describing the basic terms of the science of Applied Behavior Analysis (ABA) should help those looking to address fear issues.

It is also important to note that fear behaviors may “appear” to be irrational and therefore phobic because the fear-eliciting stimulus appears harmless to the trainer. However these fear behaviors are not irrational from the perspective of how they come about, which is the process of Respondent Conditioning (to be discussed in a future article).

One final point, when trying to address unwanted behavior it is important to focus on what we would like the bird to do instead. Training a bird “what to do” is easier and less intrusive than trying to train it “what not to do.” The latter on its own implies the use of punishment (the reduction of a behavior) and aversives (things a bird will work to avoid). Both of these are things we try to avoid in training plans whenever possible. Training a bird “what to do” involves reinforcing desired behavior, the technique upon which we try to focus. As we build the reinforcement history of the desired behavior and at the same time attempt to avoid reinforcing the unwanted behavior we will tip the balance towards the bird offering the wanted behavior.

I scared my bird!

Friday, June 19th, 2009

 

Training is an ongoing thing. No matter how well we believe our birds are trained, no matter how hard we have worked to generalize behavior, one day in our confidence we make a mistake. That happened to me this morning …

 

Mijo is a yellow-naped Amazon; he is just over a year old and has lived here at Avian Ambassadors since September last year. He actually lives in the house with us and the dogs, right in the middle of everything, pretty much. He gets to go and hang out on the porch for a good time each day with a “jungle gym” built from recycled plastic tubing and other “treasures”, and in the house his cage is in the lounge. While the day can be quiet at times it also has its share of surprises; by design I want Mijo to have as many different experiences as possible and so far our strategy seems to be working. It is not unusual for one of our re-homed dogs to bark loudly while standing within a couple of feet of Mijo. Nor is it unusual for someone to suddenly appear through the hallway right next to his cage. Over time we have worked to generalize his calm behavior to anything that happens.

 

So, this morning I got dressed and made my way to my computer, passing Mijo on the way. Suddenly he pinned himself against the roof of his cage, wings flared, eyes pulsing rapidly. What in the world happened? I quickly stepped away from him, he calmed and returned to his favorite perch. What I believe had happened was that the t-shirt I was wearing was so different to anything I had previously had on it was scaring him. The shirt, one I have not worn in a very long time is black with several large pink logos of a sailing boat class I used to sail all over the front. Typically I wear light colored shirts.

 

What to do? I could go back to the closet and change the shirt, however that was really avoiding the issue and not working to fix it. So, since the back of the shirt is plain, without the logos, I turned it around. The plain black shirt appeared less scary and I was able to reinforce Mijo for calmer behavior it its presence. We worked on this for a while intermittently; I would go off about my business and come back and reinforce the calm behavior, still wearing the shirt backwards. Once he was no longer showing discomfort I turned the shirt around. At first, as expected, there was a regression towards discomfort, nowhere near as severe as the first instance but none the less still there. Gradually over the next 30 minutes I worked to reinforce his calmer behavior in the presence of the “killer” shirt. Right now I would say his behavior in the presence of the shirt is calm, he will perform cued behaviors and willing approach me, no matter how close I am to the cage.

 

In working with Mijo to overcome this fear I feel the most important aspect of the training was that he always had choice; he could approach me or not. Choice is a powerful thing; it imbues the subject with a degree of control and that raises their confidence. Mijo was in total control of when he chose to approach or leave the scary situation. He was never coerced into “getting over it”. I have seen removal of choice as a training strategy being promoted many times by those “internet gurus.” In fact I have a couple of other articles brewing that will focus on some of these later … for now all is calm in the world of Mijo. I just need to find some brightly colored shirts to wear so that we can continue to generalize calm behavior!

 

Happy training,

Train your Parrot to Scream

Sunday, June 7th, 2009

While  the title of this article is a little “tongue-in-check” I do want to discuss how people train their birds to scream and also how at least one internet marketer suggests you do that … although they actually claimed the method would stop screaming, “… in a few days” of course.

 

I received a number of free “training” newsletters from an internet source this last week. One of them offered a way to stop your parrot screaming. Loud vocalizations are indeed a common behavioral issue for companion parrot owners so I read with interest. The advice started out quite well by suggesting one keeps a journal to indentify the times when the bird was vocalizing loudly. This is good advice and is for sure the first step in any attempt to modify that behavior. However, having started out so well and identified that the example bird screamed when someone was in the kitchen the following advice was then offered:

 

To solve this problem you can keep the pet near the kitchen and when he starts to scream throw a little bit[e to] him and keep him happy.

 

Hmm, now let me see what just happened; the bird started making noise so the owner gave him some food … sounds like the potential for positive reinforcement to me and that means that the probable future behavior is that the bird will scream when the owner is in the kitchen. So, if you want to train your bird to scream I think this is a very good technique.

 

Now, my guess is that the reason you are reading this is because what you really want is to have your bird not scream loudly, too much. I say too much because it is a fact that parrots can be loud, all parrots can be loud. It is simply a part of their nature and from time to time even the quietest bird may get a little “out of control” vocally. To get started trying to control this, just like the example above, we need to identify when the noise occurs. For example, if it is when you leave the room the noise may be your bird making a contact call. This is the function of the behavior; the need to make contact with the rest of the flock. Stopping this behavior is one of the most difficult things to do and can take a very long time. In fact if your goal is to stop the contact call you may be wasting your time trying! Probably not what you wanted to read right? However there is hope …

 

As I said the behavior has a function (making contact) so the best strategy is to try to replace the loud noises with a more acceptable vocalization for the function of contact. This is not something that can be done overnight, it takes time and patience on the part of the owner. Start by choosing a vocalization already used by your bird, one that is not so loud or high energy as the scream. Every time you hear the chosen vocalization reinforce it by responding in kind if you are out of the room or by offering a treat if you are near your bird. When the loud noise occurs ignore it, do not respond and for sure do not enter the room. What we are trying to do is to make the new sound more rewarding than the old sound. The old sound may never go away; indeed it may resurge from time to time, however by keeping the reinforcement for the “good” sound high we can hopefully keep it at the top of your bird’s preferred list of contact calls.

 

As you can imagine when we bring home a new young bird it is very important that we are aware of how we may easily train him to be a loud, obnoxious adult. Should your new bird start making a loud noise be careful how you respond.

 

Tossing a treat may well make him go quiet at that moment … however when he sees you near the treat jar …

 

When you are on the phone and he makes noise … hand over a treat and the phone may become the cue for making noise in the future.

 

By ignoring these loud vocalizations when the bird is young and by reinforcing acceptable communication we can hopefully avoid some of the really loud vocalizations in the future. The reinforcement of acceptable noises is really important; we need to give the bird a means of fulfilling the function of contact. If we simply try to stop the contact calls we are probably setting ourselves and our birds up for failure.

Reinforcing and Punishing Consequences

Wednesday, March 4th, 2009

In an earlier article I wrote about the basics of Applied Behavior Analysis so I don’t propose to cover them again here. What I would like to talk about is how one identifies a consequence as either a reinforcer or a punisher.

 

First, remember that in order to really affect a behavior the stimulus delivered or removed must be both contingent upon and contiguous with the behavior. Contingency is the if/then relationship of behavior and consequence. If the bird does this (behavior) then this (stimulus) is delivered/removed. Contiguity describes the tight relationship in time between the behavior and the contingent consequence. The closer in time these two events the stronger the effect of the consequence (stimulus) on the future behavior.

 

The labeling of a stimulus as a reinforcer or punisher is contingent upon the effect that the stimulus has upon the behavior. Since to date we have no method of knowing what an animal thinks we must rely upon observing the effect of the stimulus on the behavior, then and only then do we know whether the stimulus presented (+) or removed (-) is a reinforcer (R) or punisher (P).

 

Therefore one can not discuss if a consequence is R+, R-, P+, or P- without FIRST defining the behavior. This is why one must operationalize (write down the ABC) the behavior, then we can identify clearly the nature of the stimulus.

 

This was demonstrated in the last few days with an online discussion of the use of jesses with raptors. Jesses are the leather straps attached to the legs of raptors to restrict their movement. One writer identified the strategy as punishment, the other as reinforcement. How can that be? As I wrote above these consequences do not exist in isolation from the behavior and if we operationalize the behavior we can see that BOTH writers were to some degree correct. Assuming that the hawk is standing on the gloved hand and something occurs that startles the bird.

1A.    To be deterinined

1B.     Hawk flies from the gloved hand

1C.     The leash and jesses become taut 

Probable Future Behavior (PFB) The hawk will fly less often from the gloved hand.

Thus we have punishment (the likelihood of the hawk flying from the gloved hand is reduced) and the stimulus was added (the taut equipment placing restraint on the legs), therefore with THIS behavior we have a Positive Punishment (P+) strategy.  

2A.    The leash and jesses become taut 

2B.     Hawk returns to gloved hand

2C.     The leash and jesses become slack

Probable Future Behavior (PFB) The hawk will remain on the gloved hand more often.

Thus we have reinforcement (increased staying on the gloved hand) and the stimulus was a removal (the leash and jesses become slack and restraint is taken off legs), with THIS behavior we have a Negative Reinforcement strategy (R-).

From this example we can hopefully see that before one can know what the strategy being used is one must start by identifying the behavior. Are we talking about reducing the likelihood of flying from the gloved hand (punishment) or are we talking about increasing the bird remaining on the gloved hand (reinforcement).

This example also demonstrates that in order for our negative reinforcement strategy to work an aversive (restraint) had to be present as an antecedent. This need for an aversive in this situation should lead us to seek a different strategy for training the bird to remain on the gloved hand. The preferred approach would be to heavily reinforce the hawk for standing calmly on the gloved hand and, in a controlled environment, not to be holding the restraints, but to allow the bird to move freely off the hand to a nearby perch when it so chooses. When it returns to the hand it is once again reinforced.

 

It is worth noting that the original discussion was not really about initial training but the continued use of jesses for restraint. When working with raptors in public situations it is a matter of public safety to have this level of control of the bird, regardless of the training level. The best a trainer can do is to build a strong history of reinforcement on the gloved hand with the bird to minimize attempts to fly away. However, again in the interests of public safety, it is necessary to have the backup restraint of the equipment available.

 

In summary, talking about consequences in isolation from the behavior they are contingent upon has no meaning. The important word here is “contingent” and in order to be contingent there must be a specific behavior that is being discussed. Simply by operationalizing the behavior as was done above will reveal the nature of the consequence.

 

Please don’t forget, if you have a training question or comment please write to TrainingBlog@avianambassadors.com and if appropriate for an article I will try to address your questions and comments.
