What is a Stimulus?

Monday, November 7th, 2011

In this short article I would like to address the definition of the behavior science term “stimulus.”

The term is defined in Webster’s as:

“… [S]omething that rouses or incites to activity … an agent (as an environmental change) that directly influences the activity of a living organism or one of its parts (as by exciting a sensory organ or evoking muscular contraction or glandular secretion)”

Not the easiest of definitions to understand, so let’s try the “student” definition, also from Webster’s Online:

1.       Something that rouses or stirs to action : INCENTIVE

2.       Something (as an environmental change) that acts to partly change bodily activity (as by exciting a sensory organ) <heat, light, and sound are common physical stimuli>

Basically a stimulus is some event or thing in the environment that elicits behavior or an event or thing that follows and has some effect upon behavior; something an animal reacts to.

I will limit the discussion in this article to those stimuli that occur immediately after a behavior and serve to either increase, maintain, or decrease the strength of the behavior.

A stimulus that follows a behavior and serves to increase or maintain the strength of that behavior is called a reinforcer. They are things that the animal/bird will work to gain.

A stimulus that follows a behavior and serves to reduce its strength is called a punisher. These stimuli are things the animal/bird will work to avoid.

The procedures of Reinforcement and Punishment will be covered in a future article.

Training and Behavior Terms Defined

Monday, October 17th, 2011

As with all aspects of life, clear communication between  caregivers, trainers, and behaviorists is vitally important if we are all to help each other solve behavior problems with our birds. One tenet of clear  communication is the vocabulary used for such communications. To foster clear  communication I will be posting a series of short articles here that define and examine some of the most used and abused terms of behavior science. This will  not be a complete list, merely an attempt to improve all of our communication skills and through that improved communication develop our relationships with our birds through better training.

All of the definitions used in these articles will be taken from “Learning and Behavior” by Paul Chance. Anyone who is interested in getting good solid information about behavior science should seriously consider purchasing a copy of this book.

I will begin the series with a term that many people feel they completely understand. However, one only needs to monitor a few of the many Internet lists and forums to realize it is often misused.

Reinforcement

The procedure of  providing consequences for a behavior that increase or maintain the strength of that behavior.Learning and Behavior, Paul Chance.

This single sentence embodies several important concepts that many people appear to either gloss over or misunderstand. First and perhaps most misunderstood is that reinforcement is a procedure and not a tangible thing or object. One often hears people say “I offered reinforcement …” Reinforcement cannot be offered like a peanut. It is the process of giving the bird a peanut immediately after a behavior and seeing a future increase or maintenance of that behavior. This is the second important point in this sentence; the process followed by the trainer/caregiver is only defined as reinforcement if, after the consequence is provided, the behavior it follows actually is maintained or increased. No matter what our intention reinforcement has only been used when one is able to observe its effect on future behavior.

Closely related to reinforcement is “Reinforcer.” This is not a term directly defined by Chance in his book, however I will write about Reinforcers and Punishers in a future article that addresses the term “Stimulus.”

I hope you enjoy these short articles, if you have a term that you find confusing or would simply like better defined and explained
please feel free to email me.

How can I stop my parrot (insert behavior)?

Friday, September 23rd, 2011

I can’t tell you how many times I have been asked a question like the following:

How can I stop my parrot screaming?

How can I stop my parrot biting?

How can I stop my parrot (insert unwanted behavior)?

I am sure you see the pattern here; asking this kind of questions doesn’t lead to any kind of resolution, only frustration. Simply trying to reduce unwanted behavior somehow misses a couple of important points, not the least of which is that, typically, focusing on reducing behavior leads to the use of aversives, things the bird will work to avoid. Behavior science tells us that such techniques do not lead to a good working partnership with our birds. They in fact work against building trust.

The way to avoid this situation is through a different type of question, one that asks what you want the bird to do. For example if you have a bird that is biting your hands when you try to move him in and out of his cage ask yourself, what do I want him to do? Typically what is wanted is for the bird to step onto the hand without biting when requested. This is a behavior that can be built with patience and a large helping of positive reinforcement. Avoiding force and coercion to get the bird onto your hand gives the power of choice to the bird and through many repetitions of the behavior also builds the bird’s trust in you the trainer and the chances are the biting will be reduced.

My point here is not to teach how to train a particular behavior but to encourage you to ask questions that lead you to using the most positive least intrusive strategies for training. It is through the use of these strategies that you will build a trusting relationship with your bird.

Keep soaring,

Sid.

 

 

Free Flying Companion Parrots

Friday, August 26th, 2011

There is a growing interest in the companion parrot world in keeping birds fully flighted, i.e. not clipping wings. As someone who keeps fully flighted birds and flies them in many varied locations for the public there is a part of me that really thinks this is the only way to go. However, I also know from experience how much time and effort it takes training my birds to fly in strange locations, almost every show we do is in a different venue. I am speaking not only about initial training but also the maintenance of the behaviors trained. During the show season these birds are worked every day, regardless of there being a show or not. The thought of someone who has the pressures of a full time job and perhaps a spouse and family to be engaged with undertaking this quite honestly scares me.

It is probably worthwhile making clear exactly what free flight is. Free flight, also called “at liberty” flying, involves releasing the birds outdoors and allowing them complete choice as to where they go and how long they fly. This is quite different to what most professional bird trainers, including myself, typically do with their birds. The requirements of most shows preclude this particular form of flying in order to be able to keep the shows with some pace and direction. Having said that several professional trainers I know do fly small flocks of birds in a similar manner for show opening and closing sequences. They have five to ten birds fly out and circle the audience until the birds are ready to land on the stage or return to their housing. In fact I am presently working with a facility that will fly a flock of Macaws around their grounds, not part of a scripted show.

It is my contention that if the bird is not to be placed at risk this style of flight demands a much higher level of training for the bird and skill from the trainer. It is also my position that the typical, i.e. majority, of companion parrot owners do not have the knowledge, time, or focus required to achieve this level of training. Further I feel it unethical and professionally irresponsible for professional trainers to promote free flying companion parrots without making the demands of this pursuit clear to all.

This is not to suggest that I am opposed to keeping fully flighted birds, quite the opposite as I wrote in my blog article about clipping.

There are individuals who have proven that a companion bird can be flown free; they may have begun doing this through trial and error rather than formal training knowledge; however they were all dedicated to it, spending large amounts of time and effort on the venture. Most have had scary hours/days when birds have flown away, beyond the recall distance. Some have lost birds.

My position is simple I do not think that flying parrots outdoors is an activity that the majority of companion parrot owners should undertake.

A position on the sale of un-weaned parrots to the public

Friday, July 22nd, 2011

Over the past several years I have observed an approach being promoted to those in the companion parrot community interested in free flying parrots outdoors, they are encouraged to obtain un-weaned birds and to hand raise them themselves. This advice is not given on a one-on-one basis; it is broadcast to anyone who happens to be listening (reading). This recommendation has led me to the keyboard several times, however each time I started to write about it and to challenge its ethics I stopped short of publishing my thoughts. However after receiving several emails in the last week or so on this subject the time has come for me to take a personal position; a position that I have thought about long and hard and discussed at length with several of my professional colleagues.

 I simply cannot support the sale of un-weaned birds to the general public. There is no valid evidence I have seen presented that suggests there is anything to be gained by taking this approach other than enabling a trainer who lacks the knowledge and skill to train an already weaned/fledged/mature bird to have some early success. At the very best what is presented in support of this position is limited personal observation, rhetoric, and pseudo science. The only gain in the process is to the trainer who, for a little while at least, can apply slipshod training strategies and still fly their bird. Once a bird matures, all the skills that the trainer and bird should have had up front become required in order to maintain the desired behavior. Without the trainer having the knowledge and skill level to train a fully fledged adult bird their initial success may well result in the loss of the bird when it does mature or even during those early “random” flights.

My position is not one that I hold in isolation; I have spoken to many people in aviculture about this and asked for their positions. Not one single person supports the sale of un-weaned parrots to the general public. This is not because hand feeding a bird is a complex or hard to understand process, at least as long as all goes well. Where the skill and experience become necessary is when things go wrong. Incorrect monitoring of the birds’ development or aspiration due to poor feeding technique are just a couple of things than can and do go wrong. Encouraging people with little to no experience with birds let alone hand feeding to undertake this approach is bordering upon unethical and is irresponsible in the extreme. I encourage anyone who is looking to buy a bird that they wish to free fly to approach a reputable breeder, one that understands the importance of early development with other parrots as well as being around humans. When allowed to grow and fledge with other birds while developing trusting relationships with human caretakers the birds produced provide a solid foundation for good training to yield excellent results. This approach has been used for many years by the best breeders and their birds are those prized by the professionals. Talk to your breeder and ask them how they raise their birds before you place an un-weaned bird at risk for the sake of saving time.

There is a second aspect to this discussion and that is whether the average member of the public has the attention span, time, or even the environment to be considering free flying birds outdoors. Again, my personal position is that it takes a very dedicated individual to achieve this especially when they have a life, a job, and a family in the equation. Flying a bird once or twice a week or less will simply place those birds at risk. It takes time for the bird to develop skills, time spent in the air in many different environments and it is the skill of the trainer that sets the birds up for success in these varied environments.

I fully support those who strive to keep an unclipped parrot in their home; doing so can raise the owner’s training skills to new levels and enrich the life of the bird. Flying indoors in large buildings is excellent exercise and enrichment for all. However, I feel that free flying a parrot outdoors is something that needs very careful evaluation by the owner. While it may be true that the information on how to do it is available to all, the skill required to apply that information and safely fly the bird outdoors takes more than reading a few internet articles.
