How Intelligent Are Ravens? Surprising Facts About These Remarkable Birds

How intelligent are ravens? The answer, according to growing scientific evidence, is remarkably so. These large corvids can solve multi-step puzzles, plan for the future, and even appear to share emotions with their flock mates – a trait once thought unique to primates.

We looked into the latest research on raven intelligence and what it tells us about the complexity of the avian mind.

Ravens Can Catch Each Other’s Moods

Research has shown that ravens display emotional contagion – a form of empathy where one individual’s emotional state influences others nearby. When one raven shows signs of pessimism after a negative experience, nearby ravens begin showing similar pessimistic responses even without having the same experience themselves.

This finding is significant because emotional contagion was previously considered a hallmark of socially complex mammals. Discovering it in birds suggests that empathy may have evolved independently in multiple branches of the animal kingdom.

Problem-Solving Abilities

Ravens consistently outperform most animals in cognitive tests. They can solve puzzles involving multiple steps, such as pulling a string to access food hanging below a perch. More impressively, they can figure out these solutions on their first attempt, suggesting genuine reasoning rather than trial and error.

In laboratory tests, ravens have demonstrated the ability to use tools, barter with researchers, and even delay gratification – waiting for a better reward rather than taking an immediate one. This level of self-control is comparable to what great apes demonstrate in similar tests.

Future Planning

A 2017 study showed that ravens can plan ahead for events up to 17 hours in the future. When given a choice of objects, they would select a tool they would need later to access food from a specific apparatus, even when the apparatus was not present at the time of choosing.

This ability to anticipate future needs and prepare for them was once considered a uniquely human capability. Finding it in ravens forced scientists to reconsider fundamental assumptions about animal cognition.

Social Intelligence

Ravens live in complex social groups with shifting alliances, rivalries, and hierarchies. They remember individual relationships, track the social dynamics of their group, and adjust their behaviour based on who is watching them.

They have been observed consoling distressed group members, engaging in playful behaviour, and even appearing to deceive competitors by hiding food in false locations. This level of social sophistication requires a mental model of other individuals’ knowledge and intentions – what psychologists call theory of mind.

How Raven Intelligence Compares to Other Animals

In cognitive tests, ravens perform at a level comparable to great apes despite having brains a fraction of the size. The key difference is brain architecture. Corvid brains pack neurons more densely than mammalian brains, particularly in areas associated with higher cognition.

Among birds, ravens and their corvid relatives – crows, jays, and magpies – consistently rank as the most intelligent. Parrots are their closest rivals, with both groups demonstrating problem-solving, tool use, and social learning.

Ravens in British Culture

Ravens have held a special place in British culture for centuries. The most famous residents are the ravens at the Tower of London, where legend holds that if they ever leave, the kingdom will fall. Six ravens are kept there at all times, cared for by a dedicated Ravenmaster.

In the wild, ravens are found across much of the UK, particularly in upland areas of Scotland, Wales, and northern England. Their distinctive deep croaking call and acrobatic flight displays make them a rewarding species to observe.

Frequently Asked Questions

Are ravens smarter than crows?

Ravens and crows are closely related and both highly intelligent. Ravens tend to perform slightly better in tests involving long-term planning and complex problem-solving, while crows excel at tool use and urban adaptation. The differences are relatively small.

Can ravens talk like parrots?

Ravens can mimic human speech and a wide range of other sounds. In captivity, they have been taught to say words and short phrases. Their vocal abilities are comparable to parrots, though they are less commonly kept as pets.

Do ravens hold grudges?

Research suggests ravens can remember individuals who have cheated or wronged them and adjust their behaviour accordingly for months or even years. This long-term social memory functions similarly to holding a grudge.

How long do ravens live?

In the wild, ravens typically live 10 to 15 years, though some individuals have been recorded living over 20 years. In captivity with proper care, they can live 40 to 50 years.
