Ever wonder how animals came to possess their particular pigments? The Science behind the Colors series takes a unique approach to color in nature by offering kids simplified explanations of the how and why behind creatures’ colors. Aside from setting off a round of giggles, Blue-Footed Boobies explains that this diving bird’s feet get their bright turquoise hue from a mix of the collagen in their skin and yellow pigment from the fish they eat. Similarly, Flamingos attributes its birds’ signature pink to their diet, rich in carotenoids; the brighter the color, the healthier the bird! Jewel bright and deadly, the tiny amphibians of Poison Frogs are genetically programmed to display eye-catching patterns and colors, which act as warnings against consumption. The neon flamboyance of Sea Slugs’ star mollusks is attributed to diet or genetics, depending on the species, and helps them camouflage or signal danger (poisonous!) to predators. Excellent photos fill the books, which use short sentences, repetition, and a few advanced vocabulary words to support and challenge young readers as they learn about the animals’ diets, habitats, and life cycles. “Take a Look!” infographics and a concluding activity accommodate different learning styles, as well as introduce common nonfiction text features. Interesting and attractive, this will make a strong addition to the science shelves. —Julia Smith
