Description Animals are all around us. While we may not often see them, we can see signs that they've been there. Some signs might be simple footprints in snow or mud (tracks) and other signs include chewed or scratched bark, homes or even poop and pee (traces). Children will become animal detectives after learning how to "read" the animal signs left all around. Smart detectives can even figure out what the animals were doing! This is a perfect sequel to Mary Holland's Animal Anatomy and Adaptations series.
