What happens in just a second? A bat makes 200 high-pitched calls. A hummingbird beats its wings 50 times. A woodpecker hammers a tree trunk with its beak 20 times. A human can blink 7 times. A vulture in fight flaps its wings once. This nonfiction picture book explores the concept of time as a series of events in the natural world that take place in given units of time. Steve Jenkins's stunning collage illustrations and fascinating collection of facts create an engaging and interconnected look at time, animals, science, and the natural world.
