Crows: The tail-pulling, food-stealing bird prodigies

If you’re not yet obsessed with crows, you’re behind the times. A flood of research on the birds keeps turning up astonishingly smart behavior. They use tools: in artificial captive situations, in the wild, and by exploiting urban features like traffic. They recognize human faces. They can solve complicated multi-step puzzles.

Despite all the ability, current research barely scratches the surface of the Internet’s love affair with these animals. Floods of anecdotes and videos attribute everything from gratitude to playfulness to the corvid family—colloquially known as crows. We can even watch them appearing to find entertainment in tormenting other animals, like these apparently mischievous (or sadistic) crows causing a cat fight.

It’s hard to escape the feeling that this playfulness tells us something important about crow intelligence—it seems intuitive to take it as a further sign of prodigious animal intellect. The problem is, animal behavior is notoriously tricky to interpret. We have a tendency to project our own minds onto animals, says Alex Kacelnik, a professor of behavioral ecology at Oxford University. “We see animals doing things for which we don’t have appropriate explanations other than pretending we ourselves are doing it.”
