In the world of animals, intelligence shows up in many surprising ways. We often think of primates, like monkeys and apes, as the smartest animals because they use tools and can recognize themselves in mirrors. Orcas, or killer whales, are also known for their smarts, with their special ways of communicating and hunting together. Even dogs, our furry friends, show complex social skills and emotions.
But did you know that one of the smartest animals isn’t a mammal at all? It’s a bird! Specifically, it’s the crow, part of the corvid family, which includes crows, jays, ravens, rooks, and magpies. These birds are famous for their playful tricks and amazing intelligence. They use tools to get food and solve tricky problems. For example, they might drop nuts on roads for cars to crack open, then safely pick them up. Crows can even recognize human faces and remember people who have been mean to them for years!
Research shows that the New Caledonian crow is the smartest of all corvids. In experiments, these crows have solved problems that involve moving water to get food, similar to what kids aged five to seven can do. However, they find it hard to solve more complicated tasks that need a deeper understanding of how things work.
Crows can make tools with multiple parts, a skill once thought to be unique to humans and some great apes. They can also plan for the future, which means they can wait for a better reward instead of grabbing the first thing they see. In studies, crows picked the right tools for specific tasks and often chose to wait for a better treat.
The intelligence of crows makes scientists wonder why they evolved to be so clever. Birds and mammals split from a common ancestor 320 million years ago, yet both have developed complex brains. Birds have a brain part called the pallium, which is similar to the mammalian neocortex, possibly explaining their intelligence. Crows also have a high density of neurons in their brains, which boosts their brainpower.
One idea about why crows are so smart is their long period of parental care. New Caledonian crows are fed by their parents for up to two years, giving them time to learn how to use tools and other skills by watching. While adult crows don’t usually live in big social groups, young crows form “gangs” and interact socially, which might help them become smarter.
Interestingly, corvids sometimes interact with other animals, like wolves, which might help them find food. This ability to work with other species has led to ideas about training crows to help clean up the environment.
By studying smart animals like crows, scientists learn more about how brains develop and how intelligence works. Exploring animal intelligence helps us understand the complexities of the brain and encourages more research into other animals that might have hidden smarts.
Try creating a simple tool using everyday materials like paper clips, rubber bands, and sticks. Your goal is to design a tool that can pick up a small object, like a paper ball, from a distance. This activity will help you understand how crows use tools to solve problems.
Work in pairs to conduct a face recognition experiment. One student will wear a mask or disguise and interact with the other. After a few minutes, remove the disguise and see if your partner can recognize you. This activity demonstrates how crows can remember human faces.
Engage in a puzzle-solving activity where you need to move water from one container to another using limited resources. This simulates the problem-solving skills of New Caledonian crows and helps you think critically about resource management.
Spend some time observing birds in your area. Take notes on their behavior and interactions. Discuss with your classmates how these observations might relate to learning and intelligence in crows. This activity encourages you to think about how animals learn from their environment.
Play a game where you have to choose between an immediate reward or waiting for a bigger reward. Reflect on your choices and discuss how this relates to the planning abilities of crows. This activity helps you understand the concept of delayed gratification.

In the animal kingdom, intelligence has evolved in various ways across different species. We often consider primates as the most intelligent due to their tool use and self-recognition. Orcas are also highly intelligent, showcasing unique language skills and coordinated hunting techniques. Dog owners frequently witness their pets’ complex social intelligence and emotional sensitivity.
However, one of the most intelligent animals, surprisingly, is not a mammal but a bird: the crow, specifically the corvid family, which includes crows, jays, ravens, rooks, and magpies. Corvids are known for their mischievous and playful nature, as well as their remarkable intelligence. They use tools to forage and solve complex problems, such as dropping nuts on roads for cars to crack open and then retrieving them safely. They can recognize faces and hold grudges against those who mistreat them for years. Their problem-solving skills have been shown to rival those of a seven-year-old human.
Research has demonstrated that the New Caledonian crow is the most intelligent among corvids. In experiments, crows have shown the ability to solve problems involving water displacement to access food, similar to the cognitive abilities of five to seven-year-old children. However, they struggled with more complex tasks that required understanding specific setups.
Crows can also construct multi-part tools, a skill previously thought to be unique to humans and a few great apes. They have demonstrated the ability to plan for the future, a skill that involves delayed gratification and foresight. In studies, crows were able to select the correct tools for specific tasks and often chose to wait for a better reward rather than opting for an immediate but lesser one.
The intelligence of crows raises questions about the evolutionary reasons behind their cognitive abilities. While birds and mammals diverged on the evolutionary tree 320 million years ago, both have developed distinct brain structures. Birds possess a pallium that is organized similarly to the mammalian neocortex, which may explain their intelligence. Additionally, the density of neurons in crows’ brains contributes to their cognitive capabilities.
One theory for the evolution of crow intelligence is their extended parental care. New Caledonian crows are fed by their parents for up to two years, allowing them to learn tool use and other skills through observation. Although adult corvids often do not live in complex social groups, juvenile corvids form “gangs” and engage in social interactions that may foster their intelligence.
Interestingly, corvids have been observed interacting with other species, such as wolves, which may enhance their scavenging abilities. This propensity for interspecies interaction has led to ideas about training crows to assist in environmental cleanup efforts.
By studying intelligent species like crows, scientists gain insights into brain development and intelligence. This exploration of animal intelligence reveals the complexities of the brain and encourages further research into other species that may possess hidden cognitive abilities.
