How can we save America's wilderness areas? Wilderness and the Common Good argues that the answer to this question lies in the actions of America's citizens. Beginning with The Wilderness Act of 1964, Dr. Jo Arney examines the state of American environmental policies and how they intersect with individual citizen action. Drawing on the work of environmental and political scientists, advocates, and philosophers, Dr. Arney argues that modern civic responsibility...

Get an introduction to the importance of training dogs, both for owners and the dogs themselves. Through some powerful analogies, Professor Donaldson will put you in the mindset of your dog to show you why certain training methods don't work and others do. Learn the three key principles of dog training that will provide the foundation for every lesson moving forward.
Description
Delve into the fascinating aerodynamics of bird flight. Grasp how a bird's wings operate as an airfoil; study the forces of lift, weight, thrust, and drag; and how birds take off, land, and glide. Then explore the astonishing properties of bird feathers, as they control speed, altitude, and direction. Learn about the structure, the types, and the many roles of feathers in bird behavior.
4) The National Geographic Guide to Birding in North America: Episode 11,Essentials of Bird Migration
Description
Migration seasons provide excellent opportunities to sight unfamiliar bird species. Here, uncover the evolutionary origins of migration, and why birds migrate. Study the triggers and geographical patterns of migration, and the four principal "flyways" (migration zones) of North America. Learn how to maximize your sightings of migrating birds, and how technology can aid this.
Description
Start the proofing process, which means your dog will be proving he knows behaviors even in different conditions or environments. Professor Donaldson demonstrates how taking the same training regimen on the road can have different results and what to do to get over obstacles such as competing motivation, distractions, or problems with generalization.
Description
Begin by delving into the history of birdwatching in the U.S., from the early naturalists of the 18th century to today's highly organized activity. Then look into the origins of birds, and how they are linked evolutionarily to dinosaurs and early reptiles. Finally, explore bird taxonomy, and how their scientific classification aids us in identifying them in the field.
Description
Today, complete your review of the Passerines (songbirds). Beginning with the seed-eating towhees, explore the many varieties of New World sparrows, the juncos, and Old World buntings. Then study the tanagers, cardinals, dickcissels, grosbeaks, and vivid New World buntings, before concluding with families such as the meadowlarks, blackbirds, grackles, orioles, finches, and crossbills.
Description
One of the best ways to curb instincts in your dog is to instill impulse control. Professor Donaldson teaches you how to teach dogs to cool their jets with sit-stay, down-stay, leave it, wait, and loose leash walking. She'll also cover the three most important parameters in down-stay and sit-stay: distraction, distance, and duration.
Description
Now travel into the world of these iconic and alluring birds of prey, and their distinguishing features, ranges, and behaviors. Learn about New World vultures, including the magnificent California condor. Also encounter the osprey, kites, eagles, hawks, falcons, kestrels, and the crested caracara. Consider the challenges of raptor-watching, and their unusual history with humans.
Description
Take account of the miraculous feats of navigation performed by birds, as they migrate huge distances with amazing accuracy. Uncover the ways in which birds use visual landmarks, magnetic fields, Sun position, and the position of constellations in their migratory travels. Consider why birds migrate, the diversity of their migration patterns and habits, and the perils of these epic journeys.
Description
Learn about eleven of the best birding destinations in the Eastern U.S. and Canada. Among them, pay visits to Maine's Monnegan Island, a stopping place for a huge variety of migrants; Cape May, New Jersey, a locus of great birding sites and a haunt of famed birders; and Ohio's Magee Marsh, a legendary birding spot which hosts 338 bird species.
Description
Learn how birds mate; then examine the structure of bird eggs, how they are laid, and how laid eggs develop. Observe how nests are constructed, the diverse materials used to build them, the types and functions of nests, and the range of ingenious avian nesting behavior. Finally, explore how birds incubate their clutch, and study brood parasites, who lay eggs in the nests of other birds.
Description
Track the behavior of birds when they form flocks or colonies. Grasp the diverse benefits of group foraging, and how birds form mixed-species foraging flocks. Investigate group roosting and breeding behavior, and study fossil evidence that suggests some dinosaurs nested just like modern wading birds. Assess why birds form colonies and investigate the advantages and disadvantages of the colonies.
Description
Examine the difference between tricks and obedience. Explore why teaching tricks can be beneficial to your dog as you work through three types of trick training: non-transitive or simple actions, transitive, and behavior chains. By using the foundation of obedience training you've already established, you can teach old (and young) dogs new tricks.
Description
Get some valuable reassurance and reinforcements about continuing your training in a consistent manner as you take on the challenge of getting your dog to go down from a sit, down from a stand, sit from a down, and sit from a stand. You'll also tackle station and watch and evolve your recall from Pavlovian (rewards) to Premack (positive reinforcement).
Description
Lay a foundation for fine bird photography, starting with the basics of aperture, shutter speed, ISO (light sensitivity), and focus. Investigate the use of natural light at different times of the day, and the best equipment for photographing birds. Learn how to approach birds and capture them on camera, and consider the advantages of digiscoping (photography through a spotting scope).
Description
Explore the hatching process and the contrasting conditions for altricial chicks (born naked and helpless) versus precocial chicks (born ready to leave the nest). Delve into how birds feed their young, and the process of educating fledglings for life in the wild. Study the adaptations of siblicide (nestlings killing each other), unmated young who help raise broods, and avian communal breeding.
Description
Today, review a range of methods for attracting birds, in the field and at home. In both places, consider the use of stealth and concealment techniques, for observing while remaining unobserved. Study the remarkable ability of sounds to attract birds, and the use of water, plants, and feeders in your yard. Also learn about important ways to record your observations.
Description
Compare models which may explain female birds' choice of mates. Observe how females "test" potential mates and how males provide a basis for choice, through courtship displays or offering prime territory. Study the intricacies of avian monogamy and polygamy; take account of pair bonding in birds, extra-pair mating, sexual role reversal, and the avian equivalents of "adultery" and "divorce."
