Interesting facts about crows: why they are among the smartest birds

We have all seen a crow cawing on the parapet of a roof early in the morning. It is often thought of as an ordinary bird, yet scientists count crows among the most intelligent creatures in the world. Here are interesting facts about crows that show just how clever this black bird is.
Who are the crows?
Crows belong to the bird family "Corvidae", which also includes ravens, jays and magpies. Two crows are most common in India — the house crow, with a greyish-brown neck, and the slightly bigger, all-black jungle crow. The house crow likes to live close to human settlements and will eat almost anything. That habit lets it live easily in both cities and villages.
How clever are crows?
- They remember faces: in an experiment at the University of Washington in the United States, researchers wearing a particular mask caught some crows. Years later the crows still scolded anyone wearing that mask — even crows that had never seen the capture.
- They make tools: crows on the island of New Caledonia bend twigs and leaves into hook-like tools and use them to pull insects out of cracks in trees.
- They solve puzzles: in experiments crows have solved multi-step puzzles, such as using a short stick to get a long stick and then using that to reach food.
- Brain size: for their body size, crows have large brains — in this respect they match some monkeys and apes.
Did you know? The story of the "thirsty crow" is not just a story. In scientific experiments in 2009 and 2014, rooks and New Caledonian crows dropped stones into water to raise its level and reach floating food.
Family and society
Crows live with their families and raise their young together. Sometimes last year's young even help bring food for the new chicks. When a crow dies, other crows gather near it and make a noise. Scientists believe that by doing this they learn about the danger in that place. Crows guard their territory and will gang up to chase away even big birds of prey such as hawks and kites.
A few more facts about crows
| Item | Fact |
|---|---|
| Food | Omnivorous — grain, fruit, insects, small animals and leftover food |
| Nest | Made of twigs; in cities they even use wire and scraps of cloth |
| Voice | Many calls besides "caw", each with its own meaning |
| Lifespan | Usually 7–8 years in the wild; some live much longer |
The crow in culture and the environment
In Indian tradition, crows are offered food during Pitru Paksha. Folk tales are full of stories of the crow's cleverness. In the environment crows act as "cleaners" — by eating dead animals and leftover food they reduce filth. But India's house crow has travelled with ships to other countries and has become a threat to local birds in places such as East Africa — so there it is treated as an "invasive species".

Key points
- The two most common crows in India are the house crow and the jungle crow.
- Crows remember human faces for years and pass on news of danger to other crows.
- New Caledonian crows make tools out of twigs.
- In experiments, crows dropped stones into water to raise its level, just like the "thirsty crow".
- Crows live in families and act as cleaners in the environment.
Frequently asked questions
Do crows really recognise people?
