Book Description
“A noted naturalist explores the centrality of home in the lives of humans and other animals . . . A special treat for readers of natural history” (Kirkus Reviews). Every year, many species make the journey from one place to another, following the same paths and ending up in the same places. Every year since boyhood, the acclaimed scientist and author Bernd Heinrich has done the same, returning to a beloved patch of western Maine woods. Which led him to wonder: What is the biology in humans of this primal pull toward a particular place, and how is it related to animal homing? In The Homing Instinct, Heinrich explores the fascinating mysteries of animal migration: how geese imprint true visual landscape memory; how scent trails are used by many creatures to locate their homes with pinpoint accuracy; and how even the tiniest of songbirds are equipped for solar and magnetic orienteering over vast distances. And he reminds us that to discount our human emotions toward home is to ignore biology itself. “A graceful blend of science and memoir . . . [Heinrich’s] ability to linger and simply be there for the moment when, for instance, an elderly spider descends from a silken strand to take the insect he offers her is the heart of his appeal.” —Julie Zickefoose, The Wall Street Journal “Deep and insightful writing.” —David Gessner, The Washington Post

Book Description
“Just astonishing . . . Our natural navigational capacities are no match for those of the supernavigators in this eye-opening book.”—Frans de Waal, The New York Times Book Review Publisher's note: Supernavigators was published in the UK under the title Incredible Journeys. Animals plainly know where they’re going, but how they know has remained a stubborn mystery—until now. Supernavigators is a globe-trotting voyage of discovery alongside astounding animals of every stripe: dung beetles that steer by the Milky Way, box jellyfish that can see above the water (with a few of their twenty-four eyes), sea turtles that sense Earth’s magnetic field, and many more. David Barrie consults animal behaviorists and Nobel Prize–winning scientists to catch us up on the cutting edge of animal intelligence—revealing these wonders in a whole new light.

Book Description
For decades, as the monarch butterflies swooped through every year like clockwork, people from Canada to the United States to Mexico wondered, "Where do they go?" In 1976 the world learned the answer: after migrating thousands of miles, the monarchs roost by the millions in an oyamel grove in Central Mexico's mountains. But who solved this mystery? Was it the scientist or the American adventurer? The citizen scientists or the teacher or his students? Winged Wonders shows that the mystery could only be solved when they all worked as a team--and reminds readers that there's another monarch mystery today, one that we all must work together to solve.

Book Description
The story that unfolds in this work manifests the pursuit of one of the many historical mysteries that plague the early history of people of African descent in New York State - a mass migration of thousands of African descendants to Washington County, New York at the turn of the 19th century. The impact of this de-valued history and its absence from the historical record has distorted the recollection and remembrance of people of African descent in New York, whose ancestors were trapped in the confinement of enslavement and second-class citizenship. This unrecorded migration transpired while New York was beginning to alter its highly profitable economic system from an enslavement-based economy to a more capitalist system of production. They journeyed to Washington County, families and expectations in tow under the suggestion of a rumor of opportunity and anticipation that a better life was possible for them at the end of this arduous journey. Newly disposed of the day to day dehumanizing nature of enslavement, they struggled to find a more sustainable, prosperous and humane way of life. The correlation between my family, the Van Vrankens and the thousands of other individuals of African descent who migrated to Washington County during this period, is the personal, festering wound of omission that is still not healed or resolved. This work is a continuing byproduct of genealogical research begun by the author in 2000. It represents the second in a series of books relating to his families experiences in early New York. The first Book A Far Cry From Freedom: Gradual Abolition (1799-1827) New York States Crime Against Humanity, was published in 2006.

Book Description
This book analyzes the human consequences of urbanization and geographical mobility for residents of a major city in the Ruhr Valley of Germany during the century-long transition from an agrarian order to the industrial era. By utilizing an un-precidented combination of demographic records, it reshapes the conventional understanding of central European migration.
