Comprehensive guide to the animals of North America Fully illustrated with drawings and photographs User-friendly format makes comparing species easy

This uniquely thorough reference and guidebook offers illustrations, descriptions, and measurements for the skulls of some 275 animal species found throughout North America. The skull--the collection of bones that house and protect a creature's brain and sensory organs--is the key anatomical feature used to identify an animal and understand many of its behaviors. This book describes in words and pictures the bones and regions of the skull important to identification, including illustrations of all the bones in the cranium, leading to a greater understanding of a creature's place in the natural world. Life-size drawings and detailed measurements make this guide an invaluable reference for wildlife professionals, trackers, and animal-lovers alike.

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 "seeing" how they move through the world.
