In 2002, two scientists devised a study testing whether crows could make tools. Placing a treat in a tiny bucket, the researchers lowered it into a tube. A flexible wire lay nearby. Using it, crows Betty and Abel tried to spear the food, without success. Given access to a straight wire and a bent one, Betty used the latter to raise the bucket out of the tube. Swiping the wire, Abel did the same. Next, Betty bent the straight wire into a usable tool. With the approach and look of a graphic novel, the story is based on actual events, dramatized in the lively illustrations. Most of the text appears in speech balloons within the illustrations. An intriguing glimpse of scientists evaluating the intelligence of crows, from the Animal Masterminds series (6 titles)
