What Are the Smartest Birds in the World?

The smartest birds in the world include species like New Caledonian crows, African grey parrots, and common ravens, all of which demonstrate remarkable cognitive abilities that rival those of primates. When people ask what are the smartest birds, they’re often surprised to learn that certain avian species can solve complex puzzles, use tools, recognize human faces, and even understand abstract concepts like zero. These advanced behaviors stem from highly developed brain structures, particularly the nidopallium caudolaterale—an area analogous to the mammalian prefrontal cortex—responsible for decision-making and problem-solving. Among the most frequently studied intelligent birds, corvids (crows, ravens, jays) and psittacines (parrots, macaws, cockatoos) consistently outperform others in laboratory and field experiments.

Defining Avian Intelligence: How Do We Measure Bird Smarts?

Understanding what makes a bird “smart” requires redefining intelligence beyond mammalian standards. Unlike humans or apes, birds lack a neocortex, yet they exhibit comparable problem-solving skills through a different neural architecture. Scientists assess avian intelligence using several criteria:

• Problem-solving ability: Can the bird adapt to novel challenges?
• Tool use and manufacture: Does it create or modify objects to achieve goals?
\li>
• Social learning: Can it observe and imitate others?
• Memory capacity: How well does it recall locations, individuals, or events?
• Communication complexity: Does its vocal repertoire suggest symbolic understanding?

For example, when researchers posed the question what are the smartest birds capable of, experiments revealed that New Caledonian crows fashion hooks from twigs to extract insects—a behavior once thought exclusive to humans and great apes. This kind of innovation is a hallmark of advanced cognition.

The Top Contenders: Which Birds Rank Highest in Intelligence?

Based on decades of behavioral research, ornithologists generally agree on a shortlist of the most intelligent bird species. Below is a comparative overview:

Bird Species	Key Cognitive Traits	Notable Behaviors	Brain-to-Body Ratio
New Caledonian Crow	Tool fabrication, causal reasoning	Makes hooked tools, plans multi-step tasks	High (comparable to great apes)
African Grey Parrot	Vocal mimicry, conceptual understanding	Identifies colors, shapes, numbers; understands absence	Very high
Common Raven	Social intelligence, memory	Recalls food caches for months, deceives rivals	High
Kea (New Zealand)	Curiosity-driven learning, mechanical insight	Solves puzzle boxes, investigates human objects	Moderate to high
Blue Jay	Episodic-like memory, social deception	Imitates hawk calls, remembers thousands of seed locations	Moderate

New Caledonian Crows: Masters of Innovation

Native to the islands of New Caledonia in the South Pacific, these small black birds have become icons in animal cognition studies. They don’t just use tools—they design them. In one landmark study, a crow named “Betty” bent a straight wire into a hook to retrieve a bucket from a tube, an act of spontaneous innovation never before seen in non-humans. Researchers investigating what are the smartest birds at tool use consistently point to this species as the gold standard.

African Grey Parrots: Linguistic Prodigies

No discussion about what are the smartest birds in terms of communication would be complete without mentioning Alex, an African grey parrot studied by Dr. Irene Pepperberg for over 30 years. Alex could identify 50 different objects, distinguish seven colors and five shapes, and even grasp the concept of “same” versus “different.” He once asked, “What color am I?” after seeing himself in a mirror—suggesting self-awareness, a trait rare in the animal kingdom.

Ravens: The Strategists of the Sky

Ravens display sophisticated social intelligence. They form alliances, remember enemies for years, and engage in tactical deception—such as pretending to hide food in one location while actually stashing it elsewhere. Their ability to plan for future needs, demonstrated in controlled experiments where they selected tools they’d need hours later, places them among the few animals known to exhibit foresight.

Cultural Significance: How Human Societies View Intelligent Birds

Long before modern science confirmed their intellect, many cultures revered these birds as symbols of wisdom, trickery, or prophecy. In Norse mythology, Odin had two ravens—Huginn (thought) and Muninn (memory)—who flew across the world to bring him knowledge. Native American traditions often portray ravens as clever creators or tricksters who shape the world through wit rather than strength.

In contrast, owls are commonly associated with wisdom in Western culture—think of Athena’s owl in Greek mythology—even though they rank lower on cognitive tests compared to corvids and parrots. This highlights a key distinction: cultural symbolism doesn’t always align with biological reality. So when someone asks what are the smartest birds according to science versus folklore, the answer reveals both fascinating biology and deep-seated human narratives.

Biology Behind the Brains: What Makes These Birds So Smart?

Despite having brains the size of a walnut, some birds pack neurons more densely than primates. A 2016 study published in Proceedings of the National Academy of Sciences found that songbirds and parrots have exceptionally high neuron counts in their forebrains, allowing for greater information processing in a compact space. This neuroanatomical efficiency helps explain why a crow can outperform a monkey in certain logic tasks.

Additionally, long developmental periods play a role. Many intelligent bird species have extended juvenile phases during which they learn from parents and peers. This prolonged dependency fosters social learning, much like in human children. For instance, young crows spend up to two years observing adults before mastering tool use—a critical window for cognitive development.

Observing Smart Birds in the Wild: Tips for Birdwatchers

If you're interested in witnessing avian intelligence firsthand, here are practical tips for spotting and interpreting smart bird behavior:

1. Visit areas rich in corvid diversity: Parks, woodlands, and urban environments in North America, Europe, and Australia host crows, ravens, and jays. Watch for caching behavior—birds hiding food and later retrieving it.
2. Look for problem-solving: Place a nut inside a transparent container with a removable lid. If local crows interact with it systematically, you may witness trial-and-error learning.
3. Listen for vocal complexity: Record or note sequences of calls. Parrots and mynas produce layered sounds, sometimes mimicking environmental noises or human speech.
4. Avoid feeding wildlife directly: While tempting, regular feeding disrupts natural foraging behaviors. Instead, maintain native plants that support insect populations—key food sources for intelligent insectivores like crows.
5. Use binoculars and field guides: Identify subtle cues such as eye movement, body posture, and interaction patterns between individuals.

Debunking Myths: Common Misconceptions About Bird Intelligence

Despite growing evidence, misconceptions persist. Here are three myths worth dispelling:

• Myth: Birds have “bird brains” meaning low intelligence.
  Reality: The term is outdated and misleading. Modern neuroscience shows that avian brains are structured differently but equally capable of complex thought.
• Myth: Only parrots can talk, so they must be the smartest.
  Reality: Vocal mimicry doesn't equal intelligence. Some talking birds lack problem-solving skills, while silent ones like crows excel cognitively.
• Myth: Domestication increases intelligence.
  Reality: Captive birds may perform better in tests due to training and familiarity, but wild populations show equal or greater adaptability in natural settings.

Conservation Implications: Why Protecting Smart Birds Matters

Highly intelligent birds often face disproportionate threats due to habitat loss, climate change, and human conflict. For example, the kea of New Zealand is endangered partly because its curiosity leads it to damage cars and buildings, resulting in persecution. Similarly, African greys are heavily trafficked for the pet trade, pushing wild populations toward extinction.

Protecting these species isn’t just about biodiversity—it’s about preserving complex animal minds. Their survival contributes to ecosystem resilience and offers ongoing opportunities to study cognition across evolutionary lines. Supporting conservation groups like BirdLife International or the World Parrot Trust helps ensure these remarkable creatures endure.
