What Is the Smartest Bird? The Answer May Surprise You

The smartest bird in the world is widely considered to be the African grey parrot, a species renowned for its extraordinary cognitive abilities, advanced problem-solving skills, and impressive capacity for human language comprehension. When people ask what is the smartest bird, they're often seeking not just a name, but an understanding of avian intelligence—how birds think, learn, and adapt. Among all bird species, African greys consistently outperform others in controlled studies measuring memory, reasoning, and social learning, making them the top contender in the debate over what is the smartest bird in the world.

Defining Avian Intelligence: What Makes a Bird 'Smart'?

Before diving deeper into which bird claims the title of smartest, it's important to clarify how scientists measure intelligence in birds. Unlike mammals, birds lack a neocortex—the brain region associated with higher-order thinking in humans—but they’ve evolved alternative neural structures that support complex cognition.

Avian intelligence is typically assessed through several key indicators:

• Problem-solving ability: Can the bird figure out how to access food using tools or multi-step processes?
• Social learning: Does it observe and imitate others to acquire new behaviors?
• Memory retention: How well can it recall locations, individuals, or past events?
\li>
• Communication complexity: Can it understand symbols, syntax, or abstract concepts?
• Flexibility in behavior: Does it adapt quickly to new environments or challenges?

Birds like parrots, corvids (crows, ravens, jays), and some songbirds score exceptionally high across these domains, challenging long-held assumptions about animal intelligence.

The African Grey Parrot: A Cognitive Powerhouse

No discussion about what is the smartest bird would be complete without highlighting the African grey parrot (Psittacus erithacus). Native to the rainforests of West and Central Africa, this medium-sized grey bird with a bright red tail has demonstrated mental capabilities comparable to those of a 5- to 7-year-old human child.

One of the most famous examples is Alex, an African grey studied by animal psychologist Dr. Irene Pepperberg for over 30 years. Alex learned to identify 50 different objects, recognize seven colors and five shapes, and understand concepts like “same” and “different.” He could even answer questions such as, “What color is the wooden block?”—demonstrating comprehension, not mere mimicry.

More recent research shows that African greys can use logical inference, count small numbers, and exhibit empathy-like behaviors. Their large nidopallium—a region of the avian brain linked to executive function—plays a crucial role in their advanced cognition.

Corvids: Nature’s Feathered Engineers

While parrots dominate in linguistic and symbolic tasks, members of the corvid family—including New Caledonian crows, common ravens, and rooks—are unmatched when it comes to tool use and innovation.

New Caledonian crows (Corvus moneduloides) are particularly remarkable. In the wild, they craft hooked tools from twigs to extract insects from tree bark—a behavior passed down culturally through generations. In laboratory experiments, these birds have solved multi-step puzzles requiring them to use one tool to retrieve another, then use that second tool to get food. This kind of sequential planning was once thought to be uniquely human.

Ravens (Corvus corax) also display exceptional foresight. Studies show they can plan for future bartering scenarios up to 17 hours in advance—something even chimpanzees struggle with. They remember individual humans, hold grudges, and engage in tactical deception during feeding competitions.

So while the question what is the smartest bird often leads to the African grey, many experts argue that ravens and crows may rival or surpass them in ecological intelligence—the ability to survive and thrive in dynamic environments.

Other Contenders in the Race for Avian Intelligence

Though African greys and corvids lead the pack, other bird species exhibit surprising smarts:

• Kea (Nestor notabilis): This alpine parrot from New Zealand is notorious for its curiosity and mischief. Keas have been observed dismantling car parts, solving complex mechanical puzzles, and cooperating strategically in group tasks.
• Blue-headed macaws and cockatoos: Like greys, these parrots demonstrate self-awareness in mirror tests and can operate simple machines.
• Clark’s nutcracker: A member of the crow family, it caches up to 30,000 seeds per season and remembers their locations months later using spatial memory far exceeding human capability.
• European magpies: One of the few non-mammals known to pass the mirror self-recognition test, indicating self-awareness.

Each of these species excels in different cognitive domains, suggesting there’s no single metric for intelligence—only adaptations shaped by evolutionary pressures.

Biology Behind Bird Brains: Small Size, Big Power

For decades, scientists assumed bird brains were primitive due to their small size and smooth surface (lacking folds like the mammalian cortex). However, modern neuroscience reveals that bird brains pack neurons densely, especially in the forebrain.

A 2016 study published in Proceedings of the National Academy of Sciences found that songbirds and parrots have more neurons per gram than primates, including apes. These neurons are concentrated in regions analogous to the prefrontal cortex, enabling decision-making, impulse control, and working memory.

Moreover, birds have highly efficient metabolic systems supporting sustained brain activity. For example, ravens maintain sharp focus during flight and problem-solving despite high energy demands—a testament to their neurological efficiency.

Bird Species	Notable Cognitive Skills	Brain-to-Body Neuron Density	Tool Use?
African Grey Parrot	Language comprehension, numerical cognition, concept abstraction	Very High	Limited (uses objects symbolically)
New Caledonian Crow	Tool crafting, sequential reasoning, causal understanding	High	Yes (complex tool manufacture)
Raven	Future planning, social manipulation, memory	High	Yes (uses natural tools)
Kea	Innovative problem-solving, physical exploration	Moderate-High	Yes (improvised tools)
Clark’s Nutcracker	Spatial memory, cache retrieval	Moderate	No

Observing Intelligent Birds in the Wild: Tips for Birdwatchers

If you're interested in witnessing avian intelligence firsthand, here are practical tips for observing smart birds in natural settings:

1. Visit habitats where corvids thrive: Ravens inhabit mountainous regions, deserts, and tundra across North America and Eurasia. Look for them near cliffs or open woodlands. Watch how they interact with each other and solve problems like opening containers left by hikers.
2. Observe urban crows: In cities, American crows (Corvus brachyrhynchos) drop nuts on roads so cars crack them open—then wait for red lights to safely retrieve the food. This behavior shows timing, risk assessment, and environmental awareness.
3. Travel to parrot-rich regions: Countries like Papua New Guinea, Australia, and parts of South America host diverse parrot species. Guided eco-tours often highlight kea and sulfur-crested cockatoo behaviors.
4. Set up puzzle feeders: If you attract birds to your backyard, try placing food inside transparent boxes with lids or sliding panels. See if local species attempt to open them.
5. Record and share observations: Citizen science platforms like eBird and iNaturalist welcome behavioral notes. Your sighting could contribute to ongoing research on avian cognition.

Common Misconceptions About Bird Intelligence

Despite growing evidence, several myths persist about bird brains:

• Myth: Birds only mimic sounds without understanding. While some species do repeat noises mindlessly, African greys and other parrots clearly grasp meaning. They respond appropriately to novel sentences and categorize objects logically.
• Myth: Only mammals can feel emotions or form bonds. Ravens mourn dead companions; parrots develop deep attachments to caregivers. Emotional complexity is not exclusive to mammals.
• Myth: Bigger brains mean smarter animals. Brain size relative to body mass and neuron density matter more than absolute volume. A raven’s brain is tiny compared to a dolphin’s, yet performs similarly in certain cognitive tasks.

Why Understanding Avian Intelligence Matters

Recognizing the intelligence of birds isn’t just academically fascinating—it has real-world implications. Smarter birds adapt better to climate change, urbanization, and habitat loss. Conservation efforts must account for their behavioral flexibility. For instance, relocating intelligent species requires careful planning because they notice changes in routine and environment.

Additionally, ethical considerations arise in captivity. Highly intelligent birds suffer in barren cages. Enrichment activities—puzzles, social interaction, training—are essential for their mental health.
