When evening comes to the rain forest, the macaw and the toucan go to sleep, but the red-eyed tree frog awakens, ready for action. He is both the hunter and the hunted in the natural cycle of the forest. Joy Cowley’s spare text is geared toward the very young: “Here is an iguana. Frogs do not eat iguanas. / Do iguanas eat frogs? The red-eyed tree frog does not wait to find out. / It hops onto another branch.” Throughout she maintains a scientific perspective as she recounts the daily drama of the natural world: eat or be eaten. Nic Bishop’s exquisitely vivid color photos heighten the drama by using close-ups and freeze- frame photography. (Ages 2-6)
