Book Description
A sighting in the field is just one way birders can identify bird species. Observant nature-lovers can discover what birds are where by examining tracks, trails, and a variety of bird sign: discarded feathers, feeding leftovers and caches, pellets, nests, droppings, and skulls and bones. 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. Includes songbirds, waterfowl, owls, shorebirds, warblers, woodpeckers, nightjars, and birds of prey. For trackers, birders, and nature-lovers.

Book Description
Have you ever wondered what left behind those prints and tracks on the seashore, or what made those marks or dug those holes in the dunes? Life Traces of the Georgia Coast is an up-close look at these traces of life and the animals and plants that made them. It tells about how the tracemakers lived and how they interacted with their environments. This is a book about ichnology (the study of such traces) and a wonderful way to learn about the behavior of organisms, living and long extinct. Life Traces presents an overview of the traces left by modern animals and plants in this biologically rich region; shows how life traces relate to the environments, natural history, and behaviors of their tracemakers; and applies that knowledge toward a better understanding of the fossilized traces that ancient life left in the geologic record. Augmented by illustrations of traces made by both ancient and modern organisms, the book shows how ancient trace fossils directly relate to modern traces and tracemakers, among them, insects, grasses, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically grounded book that will serve as source both for scientists and for anyone interested in the natural history of the Georgia coast.

Book Description
An indispensable color-illustrated field guide to the tracks and signs of Europe's animals and birds This beautifully illustrated field guide enables you to easily identify the tracks and signs left by a wide variety of mammal and bird species found in Britain and Europe, covering behaviors ranging from hunting, foraging, and feeding to courtship, breeding, and nesting. Introductory chapters offer detailed drawings of footprints and tracks of large and small mammals, which are followed by sections on mammal scat, bird droppings, and the feeding signs of animals on food sources such as nuts, cones, and rose hips. The book then describes specific mammal species, providing information on size, distribution, behavior, habitat, and similar species, as well as more specific detail on tracks and scat. Distribution maps are also included. This indispensable field guide covers 175 species of mammals and birds, and features a wealth of stunning color photos and artwork throughout. Helps you easily identify the tracks and signs of a variety of mammals and birds Covers 175 species Illustrated throughout with photos, drawings, and artwork Includes informative descriptions of mammal species along with distribution maps

Book Description
If classical Lie groups preserve bilinear vector norms, what Lie groups preserve trilinear, quadrilinear, and higher order invariants? Answering this question from a fresh and original perspective, Predrag Cvitanovic takes the reader on the amazing, four-thousand-diagram journey through the theory of Lie groups. This book is the first to systematically develop, explain, and apply diagrammatic projection operators to construct all semi-simple Lie algebras, both classical and exceptional. The invariant tensors are presented in a somewhat unconventional, but in recent years widely used, "birdtracks" notation inspired by the Feynman diagrams of quantum field theory. Notably, invariant tensor diagrams replace algebraic reasoning in carrying out all group-theoretic computations. The diagrammatic approach is particularly effective in evaluating complicated coefficients and group weights, and revealing symmetries hidden by conventional algebraic or index notations. The book covers most topics needed in applications from this new perspective: permutations, Young projection operators, spinorial representations, Casimir operators, and Dynkin indices. Beyond this well-traveled territory, more exotic vistas open up, such as "negative dimensional" relations between various groups and their representations. The most intriguing result of classifying primitive invariants is the emergence of all exceptional Lie groups in a single family, and the attendant pattern of exceptional and classical Lie groups, the so-called Magic Triangle. Written in a lively and personable style, the book is aimed at researchers and graduate students in theoretical physics and mathematics.

Book Description
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.
