Spotting an animal's fresh footprints in the wild can conjure a world for the hiker: Why did the deer tracks disappear? Where did the cougar turn off the trail? What does it mean when two sets of footprints seem to coincide? This beautifully illustrated field guide, the first devoted to the tracks and signs of California animals-including birds, mammals, reptiles, amphibians, and invertebrates like spiders and beetles-blends meticulous science with field experience to provide an engaging companion for both armchair exploration and easy field identification. Filled with useful tools for the wildlife expert, and essential background and visual aids for the novice, including in-depth information about the ecology of each species, this book goes beyond basic recognition of types to interpret what animals leave behind as a way of "e;seeing"e; how they move through the world.

This fully illustrated guide--the first of its kind for North American birds--presents thorough and straightforward instruction for identifying bird families or individual species by careful examination of the unique sign they leave behind. It also offers keys to the birds' behavior in the wild.
