Dogs, cats, and other pets are easy to watch, but what about animals that live outside? This illustrated chapter book for would-be nature detectives offers information, tips, and do-it-yourself activities for observing and tracking local wildlife. Divided into different categories of clues (tracks, sheddings, scents, etc.), it provides a good general introduction to animal signs. Readers may be surprised at how much they can learn about an animal by the traces it leaves behind.
