Parrots: Navigating the Ocean of (Mis)Information

Rarely do I work with a client when I don’t spend time debunking myths. I do this patiently most of the time. I enjoy talking with my clients and getting to the truth about things. I feel genuine distress, however, for those who experience such frustration at hearing that the information they worked so hard to find and have trusted is not reliable.

Mostly, I marvel at how resistant to extinction this incorrect information has become. I have been around long enough now that I was there when some of this material was originally published decades ago. It wasn’t true then and it’s not true now. Nevertheless, it gets repeated ad infinitum online and in print. At this point, some of it qualifies as urban companion parrot legend.

Here are a few of the myths that I have addressed with people within the last two months.

Myth #1: Parrots need 10 to 12 hours of uninterrupted sleep each night.” Not true. I believe that I have put this issue to bed with this previous blog post.

Myth #2: Parrots must be kept at warm temperatures since they originate in equatorial regions. Not even close. Parrots, like all animals, acclimate to the temperatures at which they live. (Dawson, Marsh. 1989)

Myth #3: Parrots must be protected from drafts. Not true…mostly. “Contrary to popular opinion, drafts are not harmful to healthy pet birds. A draft is really nothing more than a slight movement of air, usually accompanied by a mild temperature drop. A bird’s feathers provide insulation against temperature extremes far in excess of what a draft represents.” (Animal Hospitals USA, 2018)

This information about the need to protect against drafts originated decades ago when homes were not well-insulated. People would place canaries in front of windows, around which there was an icy draft in winter. This set the bird up for illness.

These days, most of us live in well-insulated homes that don’t have drafts, unless we create them artificially by using window air conditioners. These should not be placed where they will blow directly on a parrot.

Myth #4: Cockatoos are cuddly, needs birds who require more attention than other companion parrot species. Definitely not true. The real truth is that cockatoos display different behavior characteristics depending upon how they are reared. Current rearing practices that remove babies from their parents early on and force wean them to increase profits produce birds who arrive in their homes with a wealth of unmet needs. They appear cuddly and needy because they didn’t get the nurturing they needed in their early stages. Those who are parent-reared until weaning do not display these qualities. They are independent parrots who need no more attention than others.

How does it happen that incorrect information gets repeated so often that it becomes accepted as fact? How do people get away with posting information that is untrue?

I’ve given this problem a lot of thought and have decided that the following factors all contribute to this problem. If we can understand how a problem occurs, we can get closer to a solution.

First, material written by experts is not updated regularly. This means that you can pick up readily available books and magazines that contain incorrect information. Knowledge is always evolving, but what gets published doesn’t always reflect this increased understanding.

If someone wants to reprint an older article of mine, I make sure that I update it first. My own knowledge has grown over the years and I want to ensure that people are reading what most clearly represents my current thinking. (I was wrong about a lot of things early on.) Authors of hard-cover books don’t always have that luxury.

Second, many people have a bad case of not knowing what they don’t know, coupled with a strong desire to be helpful. It feels good to dispense advice that fills a need someone else has. The opportunity to sound like an authority is very compelling. This leads to an endless amount of incorrect information being repeated online, since these helpful folks don’t check their facts before offering advice.

Third, the internet erases our ability to evaluate the signals we usually rely on when it comes to judging people and their information. Experts differ in their exact estimate of just how much of communication is non-verbal, but a range of 60% to 90% is generally accepted as accurate. (Eastman, 2018)

The largest component of any communication is non-verbal – body language, tone of voice, inflection, eye contact, facial expression. This means that, when you read online something that someone else has written, you are missing between 60% and 90% of important information about them and their message. On social media and websites, anyone can appear to be an authority.

Fourth, speaking as an authority is seductive. Some individuals who are very knowledgeable in some areas still give advice in others in which they are not, apparently unable to stop themselves.

Last, tribalism is alive and well in the “parrot community,” just as it is in politics. It is difficult to know when those publishing on social media have an agenda that is driving their posts. Much incorrect information is published with a real sense of urgency and commitment, simply because the speaker seeks to validate herself and her friends’ information.

I first decided on this topic two weeks ago, and spent some time searching online for examples to illustrate my points. Oddly, I was having a difficult time. The usual crap I read was absent from social media that day. Then, the two posts below dropped into my lap when a friend sent me these screen shots. These were published publicly on a Facebook group within the past week. Since they came to me unbidden, I deem it within the bounds of fair play to use them here.

Now, let me be clear before I go further. I believe this author has good intentions and I don’t think she meant any harm. (I did contact her personally when I received the posts and she understands that I would be using them here.) She clearly cares about nutrition and wants every parrot to be eating a healthy diet.

However, as so often happens, she dispenses valid information along with some very incorrect details. This illustrates the BIGGEST problem with online sources, which I did not list above. Most sources offer mixed advice – some good, some bad. This astronomically complicates the issue of finding trustworthy information.

Let’s examine these posts using critical thinking (the objective analysis of facts to form a judgment):

I am not a parrot behaviorist. I do not have the credentials. I am certified as a parrot behavior consultant through the International Association of Animal Behavior Consultants (IAABC).
There is no such thing as a “parrot nutritionist.” There is no educational program or certification for this title. Instead, many of us are knowledgeable about nutrition due to intensive self-study. This is an extremely complex topic due to the number of parrot species and their diverse regions of origin, making it highly unlikely that anyone will be sporting this title in the near future.
Vitamin supplementation will not cause organ damage when a parrot is severely deficient in nutrients. Added vitamins will never be a valid replacement for a good diet, but can be very helpful in the sort term. Calcium is especially helpful and is used widely in cases of chronic egg-laying. Any vitamin supplementation undertaken should always be at the direction of an avian veterinarian.
These posts were written in response to something one of my previous clients had just contributed on that forum. Unintentionally, this client had misrepresented the recommendations I had given her. The author of these posts did not contact me to verify that the information was correct before publishing her opinion.
The author dispenses nutritional advice for a parrot who has had a life-threatening medical condition in the past, without asking the individual what her veterinarian had advised her to feed.
The author herself provides a great deal of nutritional advice in her posts, although she herself is not an avian nutritionist. Her qualifications, according to her profile, are that she is a “diamontolgist” (which is misspelled) and “former esthetician.”

To correct the record for those of you who care:

I do recommend pellets as a staple in the diet, as a recent blog post discusses.
I do not recommend TOPs pellets as the primary dietary staple.
I do not recommend a plant-based, mostly veggie diet.
I do recommend limiting carbohydrates and excessive fats in the diet.
I do not recommend vitamin supplements unless a veterinarian has suggested their use.
The diet I had been coaching the client to feed had been recommended by her veterinarian.

I will leave you to arrive at your own judgement, but I think that these posts are an excellent example of the ways in which misleading information gets established as fact each second of every day online on websites and parrot forums.

So, how can you protect yourself when you go online for information about parrots? We certainly can’t ignore the value of the internet when it comes to researching and learning, but how can you identify sources that you can trust? How do you decide who really knows what they are talking about?

I suggest asking the following questions and evaluating the following criteria when deciding whose information to trust. They have served me well over the years.

What is the educational level of the author? People can certainly become well-educated through independent effort, and well-educated people can certainly publish incorrect information. Therefore, this criterion will not serve as a definitive indicator. However, I believe that those with higher education will be more likely to research their topic, have a higher commitment to publishing truth, and may be better able themselves to identify trust-worthy information.
Spelling matters. If you see someone dispensing information about Scarlet McCaws, that should serve as a red flag.
What credentials does the speaker have and are these related to the information being posted? We should hold people accountable for what they publish. It should be acceptable to ask about a speaker’s depth of experience in the topic under discussion and the speaker should graciously welcome the chance to explain how she knows what she knows.
Does the individual provide sources to support the information being published? When research about a given topic is available, it should be cited.
Does the information posted contain generalizations, such as “Amazons need….?” Behavior is a study of one. What any given parrot needs depends upon his previous socialization and training. Such declarations cannot possibly be accurate when we are speaking about parrots.
Is the speaker a recognized expert in the field? Has she published peer-reviewed journal articles? Is she certified by any institutions who recognize knowledge and achievement?
If the speaker is dispensing nutritional or veterinary information, does she herself have real work experience of any duration in the field of avian medicine?
Does the speaker publicly criticize or speak poorly of others? True professionals are respectful and are supportive of others in the field.
Follow a resource trail. Identify someone you consider to be a knowledgeable resource, and then ask who they promote and whose information they trust.

One excellent resource recommends evaluating information for: Currency, Relevance, Authority, Accuracy, and Purpose (CRAAP.) (Illinois State University. 2018) To paraphrase, this source recommends asking the following questions:

Determine the date of publication. Is the information outdated?
How applicable is the information for your needs? For what audience was the information intended?
Is the author a knowledgeable source? Examine the author’s credentials or organizational affiliation.
What is the accuracy of the content? What type of language is used and does the information seem to be well-researched?
Why was the information written? How might the author’s affiliations affect the slant or bias of the information?

This is a problem that belongs to us all. If we are ever to be able to go online and trust what we read, we must each take individual responsibility for evaluating the information we find and for being careful about what we post. Thus, the most important question of all becomes this:

Where does YOUR level of commitment lie when it comes to the welfare of companion parrots? When you are online, is it more important to be liked and validated or more important to stand up for parrots and their welfare?

If it’s the latter, you will ask for credentials before trusting information that you apply to your birds or pass along to others.

If it’s the latter, you will question everything you read and use the criteria above to evaluate the information you accept as true.

If it’s the latter, you will not repeat information or offer advice unless you yourself have hands-on experience in the area under discussion and/or have absolutely verified it to be true. “I heard it somewhere” or “I read it in a book” is not good enough.

If it’s the latter, you will support those who work hard to publish truth about parrots.

If you just want to chat online for fun or to get validation, be clear about what it is you are about. On the other hand, if you are trying to learn, then please first don your critical thinking cap. Don’t lend truth to this slogan: Critical Thinking Skills… the Other National Deficit!

It’s up to all of us to stem this never-ending tide of misinformation, disinformation and malinformation that undermines our ability to provide a good quality of life for our birds, to effectively deal with behavior problems, and to maintain their physical health over their optimal lifespans.

If we step up and accept this challenge, just think what we might accomplish when it comes to the political climate in this country! Get out there and vote everybody!

Pellets: To Feed or Not to Feed

Parrot nutrition is a special area of interest for me and one about which I am fairly passionate. The foods that a parrot eats will literally determine his experience, physically and emotionally, throughout his life. photo-1436902799100-7eb776a61f79

What we are doing as a population of bird owners is not working. Too many parrots are diagnosed daily with malnutrition and the often fatal illnesses that result. As a veterinary technician, I have seen it too often.

I also know how hard bird owners work at feeding a healthy diet. But it’s not an easy task. Information found on the internet results in both confusion and frustration. Too many websites voice strong opinions without citing sources or even acknowledging authorship in some cases.

And, parrots offer their own set of challenges. Adult parrots often don’t accept new foods readily. Second, they are biologically “programmed” to consume high energy (high fat) foods before consuming others that may offer better nutrition and more fiber. This can make them resistant to eating lower fat foods if both are offered in plenty. (Molukwu, M. 2011)

I will tell you up front that I am a strong advocate of feeding pellets – not as 100% of the diet, but as a wholesome and beneficial staple in the diet. download If you are staunchly opposed to feeding pellets, then please do not read on. This is written for those with an open mind. On the other hand, if you are undecided or wish you could get your parrot to eat pellets and can’t…then this blog is for you.

Nutrient Requirements for Parrots

I once again just recently researched published scientific information about parrot diets. It is still true that the best minds don’t know for certain what the best diet is for any parrot. They readily admit this. “Few nutrient requirements have been derived scientifically for companion birds, so nutrient requirements are based on the best guess from galliforms [chickens, ducks, turkeys, Japanese quail]”. (Orosz, S. 2006) Photo by Kris Porter

“Companion bird nutrition has virtually no tradition. In the last fifteen years progress has been made in the area of pet avian nutrition. As companion bird popularity increases, interest into researching nutritional needs has surfaced. There is still a relative lack of research information due to lack of funding, need to research “natural” diets, and the difficulty in duplicating nutritional needs in captivity.” (Ritzman, T. 2008) It is now ten years after that was written, and progress in growing our knowledge has been slow.

In the face of such a lack of knowledge, why would anyone adhere so strongly to their own prejudices that pellets aren’t important to a balanced diet when most veterinarians advocate their use so strongly? Significant advances in parrot health have been seen since they were introduced. Yet many do.

Let’s take a look at the many aspects of feeding pellets, so that you can make up your own mind about the correct choice: Should I feed my parrot pellets, or not?

The Default Diet

First, I contend that we all need a “default” diet. By this I mean a diet that our parrots will eat that we can pour out of a bag. Serving other foods can be good for adding variety into the diet to ensure nutritional balance. However, the day may come when some problem prevents you from following through with your usual parrot food preparation plans. In times of disaster, we need a food that we can serve quickly that will support good health.

This “default diet” is going to be either a seed mix or a formulated diet. If we want to protect our parrots’ health, we can’t feed seed as the main dietary staple. Not only does daily consumption of a seed mix lead to malnutrition, it sets the parrot up to develop diseases like obesity, lipoma development, atherosclerosis and fatty liver disease.

Problems with Seed Mixes

Seed mixes are deficient in 32 essential nutrients. They are very low vitamin A, which is essential if the immune system is to function correctly. If it does not, illness results. Seed mixes also lead to calcium deficiencies, which can put a bird’s life in peril. Many egg-bound birds who lay soft shell eggs do so because of the seed mix they eat. images (7)

Feeding a high-fat diet can also contribute to behavior problems. Dr. Jamie Lindstrom explains: “As we provide these high carb, high lipid diets, we’re also providing these birds with high energy. If the parrot has insufficient opportunities to expend this energy, it leads to some of the aberrant behaviors, such as screaming and biting, that we see in these birds.” (Lindstrom, J. 2010)

Fatty foods give the parrot more energy, which may be channeled into biting or screaming. With one client years ago, I improved a screaming problem simply by converting a Scarlet Macaw from a seed mix to pellets and vegetables. That wasn’t the sole solution of course, but that change was crucial to long-term success. It is also thought by many that high fat diets contribute to increased “hormonal” behaviors, such as cavity seeking, intense bonding with one person in the family, paper shredding on the bottom of the case, and territorial aggression. (Hoppes, S. 2018)

In Defense of Seed Mixes

Some defend seed mixes by pointing out that pellets have been mixed with the seed or that vitamins have been sprayed on the outside of the seeds to create a “balanced” diet. However, whether a diet is deemed balanced or not depends upon what that bird actually eats. When given the option of seeds vs. pellets, parrots usually only eat the seed. When vitamins are sprayed on the outside of seeds, this also does nothing to balance the diet. Parrots hull all of the seeds they consume. Thus, the added vitamins wind up on the floor of the cage with the shells. “For the supplement to be effective, it must be consumed in proportion to its presence in the mix.” (Brilling Hill, Inc. 1996)

Even if the attempt is made to balance a seed mix by feeding table food, the fact still remains that seed mixes contain too much fat for the average parrot. Adding table food can make this worse, as most Americans do not eat a low-fat diet. There really is no valid argument in favor of feeding a seed mix as the chosen dietary staple. That leaves us with the option of feeding pellets (formulated diets).

Types of Formulated Diets

Formulated diets come in three types. Two of the types are typically lumped together, being described as “pellets.” The third type is manufactured by combining seeds and pellets into one product. An example would be the Lafeber Nutriberries and Avicakes.

Pelleted or Extruded Diets

Not all pellets are created equal. There are two methods for manufacturing a “pelleted” diet. The first creates an extruded nugget. An example of this type would be Zupreem or Pretty Bird. Some extruded products contain sugar, which makes them a favorite among many parrots. Some say that it is easier to convert a parrot to an extruded nugget, but I have not found this to be true. images (8)

Extruded diets are manufactured by forcing a mixture of dry, ground ingredients and water through a die under high pressure and high temperature. The higher temperatures required to produce extruded diets may cause more nutrient depletion than happens with pelleted foods. In either case, nutrients that break down under higher temperatures are then added back into the product to ensure that nutrient levels are met. (Brilling Hill. 1996)

Extruded diets often, but not always, contain chemical dyes that are made from petroleum. It has not been substantiated definitively that food dyes cause behavior problems or allergies in children. However, many swear that this is the case. Choose a product without artificial coloring if this is a concern of yours.

True pellets, on the other hand, are produced by adding steam to a mixture of dry, ground ingredients and then forcing this through a die to create the shape. Generally, they are produced under lower temperatures than are extruded nuggets. Some pellet brands are organic and non-GMO. Ingredients may be less finely ground and there may be more whole-food ingredients listed on the label. Harrison’s is an example of a pelleted diet.

A word of caution: You can’t choose a pellet simply by reading the ingredient list. Organic, non-GMO, and a variety of ingredients are all good claims. However, you must also ask yourself what person or body is behind the product.

Who formulated the product? Do they have a degree in nutrition or other pertinent education? Was any research done during the formulation? Any feeding trials performed? Do they claim that the pellet is a complete diet? If the company cannot willingly and happily provide you with this information, you should consider another choice.

Arguments Against Feeding Pellets

Let’s look at some of the arguments often given for not feeding pellets:

Argument: Pellets are too dry and can contribute to a “dry crop mix” if the parrot doesn’t drink enough water.

Answer: I have never seen or heard of such a case. Parrots in the wild consume many foods, including soil, that vary widely in moisture content. It is likely that they readily adjust their water intake to account for this. If a parrot is ill or is prevented access to water, this could be an issue. However, consuming pellets poses no risk to a healthy parrot.

Argument: Pellets are boring.

Answer: They are to us. We can’t know how our parrots regard them. In any case, I’m not sure that parrots expect their food to be exciting. That said, this is why it’s a good idea to offer a variety of vegetables, limited fruit, whole grains, and legumes.

Argument: Pellets do not allow for natural foraging behavior.

Answer: They do if you include them in foraging toys and other foraging opportunities.

Argument: Pellets cannot possibly meet the nutritional needs of all species of parrots kept in captivity.

Answer: This is probably true, especially for those species who forage from a huge selection of plant materials and invertebrates in the wild. However, it’s no reason not to feed them. They offer balanced nutrition. It’s up to us to supplement the pellets with enough healthy variety as described above to make sure that we get as close as possible to offering a balanced diet.

Argument: Pellets are not palatable so parrots don’t like them.

Answer: Not true. This argument is the result of incorrectly interpreting behavior. Many people conclude this after offering pellets and finding that the parrot won’t eat them. Introducing pellets has to be done correctly to ensure acceptance. You can’t offer a choice between seeds and pellets and then conclude that the parrot doesn’t like pellets. This is like offering a two-year-old a choice between broccoli and ice cream. Further, if a parrot hasn’t seen pellets before, it may take several weeks of offering them before he accepts them.

Argument: Eating pellets leads to iron storage disease (hemochromatosis).

Answer: True… IF your parrot consumes moderate quantities of both pellets and citrus fruits or juice. Parrots do not need dietary iron and too much iron absorbed from the diet can cause a health risk. The ascorbic acid in citrus fruit causes increased absorption of iron from the diet. There is no need to feed citrus fruits and they are best avoided in a pellet-eating parrot.

Argument: Veterinarians only recommend pellets because they make money off of them.

Answer: This is so ludicrous it doesn’t even merit a response.

Argument: Eclectus parrots develop toe-tapping and wing flipping if you feed them pellets.

Answer: Actually, these behaviors cannot be blamed solely on pellets or vitamin supplementation. (Desborough, L. 2014)

Argument:: Converting my parrot to pellets is just too hard; he never eats them.

Answer: He will if you introduce them in the right way. Read on…the next section is for you.

But first, an additional argument is often presented. Why feed pellets at all? Why not just offer a healthy variety and allow the parrot to choose which foods he needs? Grey In theory, this should work. In practice, it does not. I can assure you of that from my own personal experience. In addition, “a self-selected diet in African grey parrots (Psittacus erithacus) resulted in a diet that was deficient in a total of 12 dietary components consisting of vitamins, minerals and amino acids. (Orosz, S. Lafeber.com)” For most species a combination of a formulated diet (50-80%) is ideal along with fresh vegetables, fruits, legumes, and other appropriate fresh foods.” (Ritzman, T. 2008)

Converting the Seed-Eating Parrot to Pellets

Let me reassure you about two things. First, I have never been unsuccessful in converting a parrot from seed to pellets. Second, I have never found it necessary to make the parrot hungry in order to accomplish this goal. If pellets are introduced correctly, your parrot will choose to eat them. The following is a foolproof method for getting your parrot to eat pellets:

First, make a chop mix for your bird. You may already have heard of “chop.” (While some lay claim to this idea, some version of it has been around for a long time.) Chop.FB Whole grains are cooked, then mixed with finely chopped vegetables and other items. The mix is frozen and then defrosted for feeding. It’s a good way to get a lot of variety into a parrot’s diet and offer a foraging experience. Here is an excellent article about making chop.

The only way you can screw this idea up is by including too many “goodies” (nuts, wheat-based pasta, dried fruit, etc.) into your mix. It should include only grains as close to nature as possible and a wide variety of vegetables. Other healthful additions might include flax seed, pasta made from legumes, sprouts, etc. Using the chop mix to convert the parrot to eating pellets works extremely well for birds who are used to being offered variety.

Once you have created your chop mix:

Measure the amount of seed mix consumed each day.
Mix this into an equal quantity of chop mix; offer this on a daily basis. (Your parrot will need to forage through the chop in order to eat his seeds. If he won’t go near the dish, then you will need initially to offer a small quantity of seed in a separate dish so that he doesn’t go hungry.)
At the same time, begin to offer in a separate dish a good-quality pellet. Don’t worry if he doesn’t eat them at this time. Feed fresh pellets daily in a small quantity (two or three) until he starts to eat them.
When you observe that he is eating some of the grains and vegetables, start reducing the amount of seed you mix into his chop. (You can reduce the overall quantity of seed by as little as one teaspoon a week if he is slow to eat the chop. Or, you can reduce it more quickly if he eats the chop mix readily. Take your cues from your parrot. Go as slowly or as quickly as he needs, but continue to steadily reduce weekly the amount of seed you put into the chop.)
Drumroll: At some point (once the quantity of seed mix offered gets to the point where he can no longer rely on it to meet his nutritional need for dietary fat) he will begin to eat the pellets. You won’t have to do anything else to encourage him to eat pellets.
Once he is eating the pellets well, completely eliminate the seed mix from the daily diet. Give it to the wild birds or use it to reward different behaviors that you ask him to perform.

Please note that this method is intended for species other than budgerigars and cockatiels. Generally, veterinarians recommend feeding these species fewer pellets. I convert these birds first from seed to Labefer Nutriberries and Avicakes, then add in a smaller quantity of pellets. This method has been most successful.

There are other ways, of course, to successfully introduce pellets to parrots. However, if I make this blog any longer, no one will read it!

Feeding Other Foods

If you do offer other foods in addition to the pelleted or extruded diet, you may change the nutrient balance of the diet as a whole, which could be problematic. This only becomes a serious problem if you are adding in seeds or nuts. As previously stated, parrots will eat high fat foods in preference to formulated foods. The best practice is to reserve any treats, whether seeds or nuts or cheese, for use in reinforcing behaviors that you have asked the parrot to do.

If you supplement with fruits and vegetables, you are less likely to upset the total nutrient balance of the diet. These foods are high in water content, so even if they make up a high proportion of dietary weight, they have a relatively small influence on the balance of nutrients supplied by dry pellets or extrusions that contain much less water. (Brilling Hill, Inc. 1996)

Veterinarians generally recommend that formulated foods make up between 50% and 80% of what is consumed. My best advice is to consult your own veterinarian as to what brand and amount to feed.

A Few Cautions

If pursuing a diet change, please weigh your parrot regularly to guard against weight loss. This is easier than trying to figure out what the parrot is actually eating. (An exception to this would be if your veterinarian has recommended weight loss for your parrot and is monitoring your progress with this.) Otherwise, weigh your parrot once or twice a week. You can use a good-quality kitchen scale. Alternatively there are many websites that sell scales with perches.

You should also be monitoring the droppings as an added precaution. What goes in must come out. If you have more than one bird in the cage, please also increase the number of food dishes. You should eliminate any competition for food as the diet conversion is completed.
