Crow Smarts: Inside the Brain of the World’s Brightest Bird (Scientists in the Field series)

This book observes New Caledonian crows and their use of leaves to obtain food. The birds fashion and manipulate the leaves, then demonstrate these techniques to their young. It also explores evidence that these crows can understand a causal idea: that one action may lead to a later result. Sketches, color photographs, and back matter accompany the look at crow behavior and intelligence in New Caledonia.
