Birds on the Brain

Clever Crows and the Wisdom of Not Being TOO Rational

by Michael Balter

A new study finds that both young children and members of the crow family are good at solving this problem, but children appear to learn it in a very different ways from birds.

Recent studies, particularly ones conducted by Nicola Clayton’s experimental psychology group at the University of Cambridge in the United Kingdom have shown that members of the crow family are no birdbrains when it comes to cognitive abilities. They can make and use tools, plan for the future, and possibly even figure out what other birds are thinking, although that last claim is currently being debated.

A few years ago, two members of Clayton’s group showed that rooks can learn to drop stones into a water-filled tube to get at a worm floating on the surface. And last year, a team led by Clayton’s graduate student Lucy Cheke reported similar experiments with Eurasian jays: Using three different experimental setups, Cheke and her colleagues found that the jays could solve the puzzle as long as the basic mechanism responsible for raising the water level was clear to the birds…
