What Is Considered The Dumbest Bird Species?

Birds display incredibly complex behaviors and advanced cognitive abilities. However, some species are known for being less intellectually gifted than others. When it comes to bird intelligence, which feathered friends end up at the bottom?

If you’re short on time, here’s a quick answer to your question: The domestic chicken is often considered to be one of the least intelligent birds based on behavioral studies and brain anatomy.

In this in-depth article, we’ll examine how researchers study and measure bird intelligence across species. We’ll look at brain structure differences and behavioral traits that point to lower intelligence. And we’ll countdown some of the birds believed to be the least smart in the avian world.

How Bird Intelligence is Studied and Measured

Examining Brain Anatomy

One way researchers study bird intelligence is by examining their brain anatomy. By comparing the size and structure of different regions of the brain, scientists can gain insights into a bird’s cognitive abilities.

For example, the size of the forebrain, which is responsible for problem-solving and learning, can indicate the level of intelligence a bird possesses. Additionally, scientists study the presence of specific brain structures, such as the hippocampus, which is associated with spatial memory and navigation skills.

Research conducted by Dr. Irene Pepperberg on the African Grey Parrot, Alex, revealed that these birds have a high level of intelligence. Alex was able to learn and understand over 100 words and could even hold meaningful conversations with humans.

This research has provided valuable insights into the cognitive abilities of birds and has challenged the notion that intelligence is solely a human trait.

Testing Cognitive Abilities

Another method used to study bird intelligence is through various cognitive tests. These tests are designed to measure a bird’s problem-solving skills, memory, and ability to learn. For example, researchers might present birds with puzzles that require them to manipulate objects to obtain a reward, or they might test their ability to recognize and remember specific patterns.

One study conducted at the University of Cambridge found that New Caledonian crows possess remarkable problem-solving abilities. These birds were able to use tools to extract food from tubes, a skill previously thought to be unique to humans and a few other primates.

This research suggests that bird intelligence is more complex and diverse than previously believed.

Analyzing Behavioral Traits

In addition to brain anatomy and cognitive tests, researchers also analyze behavioral traits to assess bird intelligence. Observing social interactions, communication patterns, and foraging strategies can provide valuable insights into a bird’s cognitive abilities.

For example, the intelligence of the common raven has been studied extensively. These birds are known for their problem-solving skills and their ability to communicate with each other using a variety of vocalizations.

They are also skilled at using their beaks and claws to manipulate objects and extract food. By studying these behavioral traits, scientists can gain a deeper understanding of the intelligence and adaptability of bird species.

Bird Species Considered Least Intelligent

Domestic Chicken

When it comes to bird intelligence, the domestic chicken is often considered one of the least intelligent bird species. While chickens may excel in certain areas such as finding food or recognizing their flock, they are generally not known for their problem-solving abilities or complex behaviors.

Despite this, chickens have their own unique characteristics and social hierarchies within their flocks, making them fascinating creatures to observe.

Domestic Turkey

Another bird species that is often considered less intelligent is the domestic turkey. Turkeys are known for their curious nature but are not typically recognized for their cognitive abilities. However, it’s important to note that intelligence can be difficult to measure and can vary within individuals of the same species.

While turkeys may not exhibit the same problem-solving skills as some other birds, they have their own unique behaviors and survival strategies.


The ostrich, the largest bird species in the world, is often associated with its inability to fly. In terms of intelligence, ostriches are not known for their problem-solving abilities or complex behaviors.

However, they possess exceptional speed and endurance, making them well-adapted to their environment. Ostriches also have unique parenting behaviors, with males incubating the eggs and females taking on the role of protecting the nest.


Similar to the ostrich, the emu is a flightless bird species that is often considered less intelligent. Emus are known for their strong instincts and adaptability to harsh environments, but they are not typically recognized for their cognitive abilities.

Despite this, emus have their own unique behaviors, such as elaborate courtship displays and communal nesting habits.


While pigeons have shown impressive feats in certain areas, such as their homing abilities, they are often perceived as less intelligent compared to other bird species. Pigeons have been trained to perform various tasks, including delivering messages and participating in races.

However, their cognitive abilities are not as advanced as some other bird species, and they are not known for their problem-solving skills.

It’s important to remember that intelligence can be difficult to define and measure, and each bird species has its own unique set of behaviors and adaptations. While some bird species may not exhibit the same level of problem-solving abilities as others, they still play important roles in their ecosystems and have fascinating characteristics worth exploring.

Why Some Birds Have Lower Intelligence

While birds are generally considered to be intelligent creatures, there are some species that are known for their lower intelligence. Understanding why certain birds have lower intelligence can provide insights into their unique characteristics and behaviors.

Domestication and Captive Breeding

One reason why some birds may have lower intelligence is due to domestication and captive breeding. Over generations of being bred in captivity, certain bird species may have lost some of their natural instincts and cognitive abilities.

This can be observed in domesticated birds, such as certain breeds of chickens, which have been selectively bred for specific traits and may lack the problem-solving skills and adaptability seen in their wild counterparts.

No Need to Innovate or Use Tools in the Wild

In the wild, birds often evolve intelligence and problem-solving skills in response to environmental challenges and the need to find food and survive. However, some bird species have evolved in environments where there is less need for innovation or tool use.

These birds may have access to abundant food sources or lack natural predators, reducing the need for complex cognitive abilities. For example, the kiwi bird of New Zealand has adapted to its environment by becoming flightless and relying on its excellent sense of smell to find food, rather than using complex problem-solving skills.

Lower Predation Pressures

Another factor that may contribute to lower intelligence in certain bird species is lower predation pressures. Birds that are not highly targeted by predators may not need to develop advanced cognitive abilities to evade capture or outsmart their predators.

This can be seen in species like the emu, which is the second-largest living bird and has few natural predators due to its size and strength.

It’s important to note that intelligence is a complex trait that can vary widely even within bird species. While some species may be considered less intelligent based on certain criteria, it’s essential to appreciate the unique adaptations and behaviors that each bird species has developed over time.

Impact of Limited Intelligence on Bird Behavior

While all bird species possess unique characteristics and abilities, some are considered to have limited intelligence compared to others. This limited intelligence can have a significant impact on their behavior and interactions with their environment.

Let’s explore the various ways in which limited intelligence affects bird behavior.

Poorer Problem-Solving Skills

Bird species with limited intelligence often struggle with problem-solving tasks. They may have difficulty finding food, building nests, or adapting to changing circumstances. For example, some studies have shown that certain bird species have a harder time solving complex puzzles compared to more intelligent species.

This can affect their ability to thrive in challenging environments and can make them more vulnerable to predation or competition.

Less Advanced Communication

Intelligence plays a crucial role in communication among birds. While all birds have the ability to communicate, species with limited intelligence may have a more basic and less diverse range of vocalizations.

This can impact their ability to convey information, such as warning signals or mating calls, effectively. As a result, they may have a harder time attracting mates or warning their flock about potential dangers.

Simpler Social Structures

Intelligence plays a role in the complexity of social structures among bird species. Birds with limited intelligence tend to have simpler social structures, with less hierarchical organization and fewer complex interactions.

This can limit their ability to form strong social bonds or engage in cooperative behaviors. For example, certain bird species with limited intelligence may have less efficient hunting strategies compared to more intelligent species that can work together to catch prey.

More Instinctual Reactions

Birds with limited intelligence rely more on instinctual reactions rather than cognitive decision-making. They may have a harder time adapting to new situations or learning from past experiences. This can make them more predictable in their behavior and less able to respond flexibly to changing circumstances.

For example, when faced with a new predator, a bird species with limited intelligence may have a default response of flight rather than assessing the situation and choosing the most appropriate response.


While avian intelligence exists on a broad spectrum, certain birds like chickens, turkeys, and ostriches consistently score lower on measurements of brain structure, cognition, innovation, and complex behaviors.

Rather than making them less amazing, these birds show intelligence evolving as adaptations to specific niches and environments. And their unique traits continue to reveal captivating insights into the avian mind.
