Thinkers of the Jungle. The Orangutan Report - Willie Smits, Jay Ullal, Gerd Schuster

It is no exaggeration to describe the book as a sensation. A swimming orangutan is seen for the very first time in world-exclusive photos, although research still assumes that great apes cannot swim. Orangutans are shown angling with sticks this form of tool use was unknown until now. Jay Ullal's photos are simply the best to be found in this field. Almost ten thousand photos were shot during five trips to Borneo and Sumatra, including 40 world-exclusive gems. These, and hundreds of other fascinating photos, are contained in this book.
