A Doll’s Eyes: Functional Autism in Parrots

When We Recognize Suffering

Imagine walking into a home and discovering a nearly seven-year-old girl lying on a filthy mattress, wearing nothing but a soiled diaper, surrounded by excrement and insects. What would you do?

Most of us would react immediately. We would recognize the conditions as abuse and demand that something be done.

Yet when similar deprivation occurs in the life of a parrot, it often goes unnoticed. Not necessarily because people are cruel or indifferent, but because they do not understand what constitutes suffering for these extraordinary animals.

We recognize neglect in a human child because we understand something about human needs. Children require affection, social interaction, stimulation, opportunities to learn, and an environment in which they can develop. But how many people understand that parrots have their own equally important, species-specific needs?

The Girl With the Doll’s Eyes

In 2008, the St. Petersburg Times published Lane DeGregory’s extraordinary story of Danielle, a young girl discovered living in appalling conditions in Plant City, Florida.

For much of her early childhood, Danielle had experienced profound neglect and social deprivation. When authorities intervened, she could not speak, had severe developmental difficulties, and struggled with basic activities that most children learn through ordinary interaction with their families.

Her eyes appeared distant and unresponsive, giving the impression of a child withdrawn from the world around her. They were described as a doll’s eyes.

Danielle eventually found a loving adoptive family. With patient care, attention, and professional assistance, she began learning skills that had previously been beyond her reach.

Her story illustrates both the devastating consequences of deprivation and the remarkable capacity of a living being to respond when given opportunities for learning, security, and companionship.

Although human development and parrot development are not identical, Danielle’s experience raises an important question: What happens when an intelligent, highly social creature is denied the experiences necessary for normal development?

When a Parrot Becomes an Inconvenience

People rarely acquire a companion parrot intending to neglect it. Most are attracted by the bird’s beauty, intelligence, affectionate behavior, or remarkable ability to imitate human speech. Unfortunately, many have little understanding of what they are bringing into their homes.

A parrot is not simply a decorative animal that occasionally talks. It is a complex, intelligent creature whose behavior has been shaped by millions of years of evolution. These are, quite literally, living dinosaurs. And they are not domesticated animals in the same sense as dogs and cats.

A large cockatoo may have the curiosity and determination of a small child, the destructive capabilities of a powerful beak, and a voice that rivals a jet aircraft at takeoff.

When these characteristics emerge, an unprepared guardian may become frightened, frustrated, or overwhelmed. The bird screams. It bites. It destroys expensive objects. It refuses to cooperate.

The guardian may interpret these behaviors as stubbornness, spite, or disobedience. But what if the bird is simply behaving like a parrot?

Without an understanding of its natural behavior and learning history, the guardian may respond by restricting the bird’s freedom, reducing interaction, or moving its cage into an isolated room. Eventually, the bird that was once welcomed into the family becomes an inconvenience.

And an intelligent, social creature may spend years, sometimes decades, confined and misunderstood. Not because it was inherently defective or malicious, but because the people responsible for its care never learned to understand it.

The Formative Years: Learning to Be a Parrot

There is another parallel between Danielle’s experience and the lives of many companion parrots. Both humans and parrots undergo important periods of development during which their experiences help shape how they interact with the world.

During childhood, we learn to communicate, develop social relationships, explore our surroundings, and respond to the behavior of others. Parrots must learn many of these things as well, although their development follows a different timetable.

In the wild, young parrots grow up surrounded by parents, siblings, and other members of their flock. They have opportunities to observe, explore, communicate, and learn the behaviors necessary for life among their own kind.

Yet many companion parrots begin life under very different circumstances. Some are removed from their parents at an early age and raised primarily by humans. Others spend important developmental periods in environments that offer little opportunity for normal social interaction. They may learn to depend on humans without developing adequate opportunities to interact with other parrots.

What happens when these birds reach sexual maturity? Their behavior changes, as we should expect it to. They may become more selective about social partners, more territorial, or more interested in reproductive behavior.

But the people who purchased an affectionate baby bird may not understand these changes. The bird that once eagerly accepted attention may now bite, scream, or resist handling. Instead of recognizing the animal’s changing biological and behavioral needs, the guardian may conclude that something has gone wrong with the bird. And so the bird loses the companionship it once enjoyed.

This is where the consequences of an inadequate learning history may become especially apparent. Dr. Susan Friedman and Bobbi Brinker, in their article Early Socialization: A Biological Need and the Key to Companionability, discuss the importance of early experience in the development of social and emotional behavior.

The lesson is not that development ends at a particular age. Learning continues throughout life. Rather, early experiences can have lasting consequences, and correcting the effects of deprivation may require considerable patience, appropriate environmental changes, and carefully designed learning opportunities.

A parrot cannot be expected to develop skills it has never had the opportunity to learn.

Flight: Taking Away the Means of Escape

Danielle spent much of her childhood confined to a room, unable to explore the world around her. In a sense, her freedom of movement had been taken away. We do something remarkably similar to parrots when we routinely clip their wings.

Flight is not simply a convenient means of transportation for a bird. It is an essential part of its natural behavioral repertoire. A wild parrot confronted with danger has options. It can move away. It can fly to another location. It can put distance between itself and something frightening.

Now consider a companion parrot whose wings have been clipped. A frightening person approaches. The bird attempts to retreat, but its opportunities for escape are limited. What options remain? It may threaten, lunge, or bite.

We then label the bird aggressive, when its behavior may be an attempt to escape or avoid something it finds frightening. The beak, which has many functions, becomes an important means of defense when other options are unavailable.

This does not mean that every clipped bird will become aggressive, or that every bite results from fear. Behavior is influenced by its immediate circumstances and learning history. But we should recognize the consequences of restricting an animal’s ability to move away from situations it finds threatening.

There are legitimate safety considerations when managing flight in a human home. Windows, ceiling fans, open doors, and other hazards require careful attention. Nevertheless, permanently restricting flight should not be treated as a substitute for providing a safe environment and teaching appropriate behavior.

Whenever possible, parrots should have opportunities for safe, controlled flight and other forms of physical activity. These animals evolved to move through the air. We should think carefully before denying them that opportunity.

Environmental Enrichment: The Need to Destroy

Imagine giving a child a toy that cannot be manipulated, taken apart, explored, or used in any meaningful way. Now imagine that this is the child’s only toy for months or years. We would hardly consider that an adequate environment for learning and development.

Yet parrots are routinely given toys that offer little opportunity to engage in their natural behaviors. Parrots chew. They shred. They explore objects with their beaks and feet. In the wild, these activities are part of their everyday lives.

A companion parrot may spend hours dismantling a wooden toy that its guardian purchased only yesterday. And what does the guardian say? “I bought him a new toy, and he destroyed it!” Precisely. That is what the toy was for.

A parrot toy is not necessarily supposed to remain attractive and intact. Its purpose is to provide opportunities for activity, exploration, and the expression of natural behavior. Destruction is often evidence that the toy is serving its intended function.

This does not mean every toy is suitable. Materials must be safe, appropriately sized, and free from hazards such as toxic substances or dangerous entanglements. Nor does every parrot enjoy the same activities.

Some prefer soft wood. Others enjoy paper, cardboard, or more challenging objects. Some birds must gradually learn to interact with unfamiliar materials. The important question is not how long a toy lasts. It is what opportunities the toy provides.

Foraging is equally important. Wild parrots spend substantial portions of their day searching for and processing food. A companion bird that receives all its food in a bowl may have few opportunities to engage in these activities.

Foraging toys, appropriately prepared food puzzles, and opportunities to manipulate safe materials can help restore some of the behavioral complexity missing from captivity. Environmental enrichment is not a luxury. It is part of responsible animal care.

When we deprive an intelligent animal of opportunities to explore, learn, manipulate objects, and exercise some control over its surroundings, we should not be surprised when behavioral difficulties develop. The problem is not necessarily the bird. Sometimes the problem is the world we have created for it.

A Clean Cage Is Not Necessarily a Healthy Environment

When authorities discovered Danielle, she was living in conditions that no child should ever experience. Her surroundings were filthy, and she had been denied even the most basic standards of care.

We recognize such conditions as unacceptable for a human being. Yet many companion parrots live in environments that fall far short of their physical and behavioral needs.

A cage may appear clean at first glance, but appearances can be deceiving. Food debris, droppings, and moisture can accumulate beneath cage grates, around perches, and in places that are difficult to reach.

The upper surfaces of cage bars may be wiped clean while contamination remains underneath. Damp bedding and accumulated organic material can encourage microbial growth, including molds that may present serious health risks.

A parrot’s respiratory system is remarkably efficient, but that efficiency also makes attention to airborne contaminants especially important. Cleanliness is not simply a matter of appearance.

Cages, perches, feeding equipment, and surrounding surfaces must be cleaned regularly using methods and products appropriate for birds. But sanitation is only one part of the picture.

A perfectly clean cage can still be an impoverished environment. A parrot needs opportunities to move, explore, interact, and engage in meaningful activities. We must consider both physical health and psychological welfare.

The Loneliness of a Flock Animal

Most parrots are highly social animals. In the wild, their lives are organized around relationships with other birds. They communicate, forage, rest, and respond to changes in their surroundings within complex social environments.

Yet we frequently expect companion parrots to spend much of their lives alone. A bird may receive attention for a short period in the morning before its guardian leaves for work. It may then spend the next eight or ten hours confined to a cage, waiting for someone to return. Sometimes the isolation continues into the evening.

Occasionally, a bird is left with little meaningful interaction for an entire weekend. We should ask ourselves what such a life means to an animal whose natural history is built around social relationships.

Not every parrot responds to isolation in the same way. Some become excessively vocal. Others develop repetitive behaviors, withdraw from interaction, or engage in feather-damaging behavior.

These behaviors can have multiple causes, including medical conditions, and should never be attributed to isolation without careful assessment. Nevertheless, inadequate social opportunities are an important welfare concern.

The solution is not simply to place any two parrots together. Birds have individual histories, preferences, and compatibility requirements.

Some may benefit from carefully managed contact with compatible birds. Others may require substantial human interaction, gradual social learning, and opportunities to choose whether to participate.

What matters is that we recognize social contact as a need rather than an occasional reward. Companionship should not be something a parrot receives only when it is convenient for us.

Learning to Speak Their Language

Danielle’s profound deprivation affected her ability to communicate. Without ordinary opportunities for social interaction and learning, she had not developed many of the communication skills expected of a child her age.

There is another lesson here for those of us who live with parrots. We are fascinated by their ability to imitate human speech. We teach them words, encourage them to repeat phrases, and delight when they appear to carry on conversations. But how much effort do we devote to learning their language?

Parrots communicate through vocalizations, body posture, movement, feather position, and interactions with their surroundings.

A bird may lean away from an approaching hand. It may move toward a preferred person, lower its head, raise its feathers, or shift its position on a perch. These behaviors provide information about what the bird is experiencing and how it may respond.

Their meaning, however, depends on context. A raised crest does not always indicate aggression. A lowered head does not necessarily mean that a bird wants to be touched. We must learn to observe the whole animal and the circumstances in which its behavior occurs.

This is where the science of behavior becomes particularly valuable. By observing antecedents, behavior, and consequences, we can begin to understand the relationships between environmental events and an individual’s actions.

A functional assessment helps us develop informed hypotheses about why a behavior occurs. When appropriate, a carefully designed functional analysis can help test those hypotheses.

The goal is not simply to stop behavior we find inconvenient. It is to understand what the animal is communicating and arrange conditions in which more desirable behavior can develop.

Research has also revealed remarkable complexity in parrot vocal communication. Studies of wild parrots have documented individually distinctive vocal signals, including contact calls associated with particular individuals.

These findings remind us that parrot communication is far more sophisticated than the simple imitation of human words. We have spent generations teaching parrots to speak our language. Perhaps it is time we devoted equal effort to understanding theirs.

Behind the Bars

Danielle’s story is heartbreaking. Yet it also reminds us that meaningful improvements can occur when an individual receives appropriate care, security, and opportunities to learn.

Her experiences cannot be undone. But her future need not be defined entirely by her past. The same principle offers hope for parrots that have experienced deprivation.

A bird that has spent years in isolation may initially fear unfamiliar people, objects, or situations. It may scream, threaten, bite, withdraw, or engage in repetitive behavior.

We should not assume that such behavior reflects a defective personality or an animal that cannot change. Behavior develops through interactions between biology, learning history, and the current environment.

By changing those conditions, we can often help an animal acquire new skills and experience a better quality of life. Progress may be slow. Some difficulties may persist despite excellent care.

But even modest improvements in an animal’s ability to make choices, interact with its surroundings, and participate in meaningful activities can be important.

The animals in our care do not need us to make them behave like humans. They need us to understand what it means to be a parrot.

Behind the bars of cages throughout the world are intelligent, sensitive creatures waiting for someone to recognize their needs. Some have spent years without meaningful companionship.

Others have learned that approaching hands predict frightening experiences, or that their attempts to communicate will be ignored.

When a parrot retreats, threatens, or cries out, we should ask what its behavior tells us about its experiences. We should ask what we can change.

And above all, we should remember that the animal did not choose the circumstances in which it lives. We did. The responsibility for making those circumstances better belongs to us.

Author’s Note

This essay was originally written between 2014 and 2018. The term functional autism was used descriptively to draw attention to behavioral similarities between individuals experiencing severe deprivation and certain outward behaviors associated with autism. It was not intended to suggest that autism is caused by neglect, nor that parrots can be diagnosed with human autism spectrum disorder. Similar-looking behaviors may have different causes and functions.
