Crows are able to look at a handful of four-sided shapes and correctly distinguish those that exhibit geometric regularity from those that don't, according to a provocative new study. It's the first ...

A recent study showed that carrion crows could be trained to use tools, suggesting flexibility in this intelligent behavior.

Crows have long been known for their clever tricks, but new research shows they may be even smarter than we thought. Scientists have discovered that crows can recognize geometric patterns—a skill once ...

Crows have a sense of geometric intuition much like our own, a new study reveals. They can detect the 'odd one out' in a set of geometric shapes, and have an affinity for geometric regularity – shapes ...

Animal training can teach carrion crows to use a stick tool to retrieve food. With increasing practice, they not only demonstrate great skill and achieve their objective in a few steps, they also ...

Crows are arguably among the smartest creatures on the planet, possessing some cognitive abilities that rival those of 5- to 7-year-old human children. Now, a new study adds basic geometry to the list ...
