What sets crows apart is a unique combination of cognitive abilities that researchers continue to marvel at. Let’s unpack some of these traits and fathom why crows are so smart.

Problem-Solving and Adaptability

Crows have a remarkable ability to adapt to different situations and solve problems. They use tools like sticks to extract insects from tree bark, or hooks to retrieve food from hard-to-reach places.

Moreover, crows have demonstrated basic counting skills, allowing them to keep track of hidden objects or predators in their environment. These problem-solving skills and adaptability contribute to their overall intelligence.

Experimental Insights from Aesop’s Fable


In this video, a classic tale from Aesop’s Fables about a thirsty crow is brought to life through a series of experiments. The fable speaks of a crow who, unable to reach the water in a pitcher, drops stones into it to raise the water level and quench its thirst. Mirroring this tale, New Caledonian crows were trained to pick up and drop stones into a tube to access a floating reward, demonstrating their problem-solving acumen.

These crows quickly figured out that dropping stones would raise the water level, enabling them to reach the reward. Further experiments revealed that the crows could discriminate between sinking and floating objects, choosing the former to effectively raise the water level. They also preferred solid over hollow objects for this task.

However, their performance dipped when they had to deal with wide versus narrow tubes or if part of the tube apparatus was hidden, indicating a need to see the cause and effect to understand the problem fully.

These findings not only bolster the narrative of crows’ problem-solving abilities but also suggest that more research is required to understand the full spectrum of their learning and thinking capabilities.

Self-Awareness and Social Intelligence

Another factor that highlights crow intelligence is their self-awareness and social intelligence.

Crows have passed the mirror test, demonstrating they can recognize and understand their reflection. Furthermore, they can recognize individual human faces and remember those who threaten their safety.

Their complex social behaviors, including cooperation and communication with other crows, underline their intelligence and elevate them as one of the smartest creatures in the animal kingdom.

Advanced Cognitive Capacities of Crows

Beyond basic problem-solving, the intellectual prowess of crows encompasses advanced cognitive capacities akin to those of certain mammals.
