To love whooping cranes, sandhill cranes, and Kirtland's warblers was easy for Larry Walkinshaw. Saving them from extinction engulfed his life. Journey into Walkinshaw's incredible life drama to discover how his adventures led him onto the pinnacle of ornithological attainment-into that world of birding he so loved and mastered. Join him in the global wilderness of marshlands, deserts, and tundra seeking nature's truths as birds literally hatched, fluttered, and died in his hands. On the Wings of Cranes reveals how cranes and Walkinshaw became synonymous. Recognized as "The Father of International Studies of Gruiformes," he led in the salvation of endangered whooping cranes, greater sandhill cranes, and Kirtland's warblers. At times, heartbreak entered his life, but his perseverance held as he took calculated risks, sacrificed, and struggled to save endangered birds. Beneath the mask of his deliberate and reserved personality resided a uniquely complicated genius who desired to serve both nature and humankind. On the Wings of Cranes extends an invitation to respond to the powers of inspiration, motivation, and self-discipline. The theme of Walkinshaw's life is birding-inspiration its message. Soar with Walkinshaw, from take-off to landing, on the wings of cranes.

In the past two centuries, cowbirds have increased in numbers and extended their range across North America, while many of the native songbird species whose nests they parasitize to raise their young have declined. This timely book collects forty essays by most of the principal authorities on the biology and management of cowbirds. The book's goals are to explore the biology of cowbirds, the threats they pose to host species and populations, and the management programs that are being undertaken to minimize these threats. The book is organized into five sections, each with an extended editors' introduction that places the contributions in a broad, up-to-date setting. The sections cover: ? The changing abundance of cowbirds and the ways in which their numbers can be estimated. ? Host choice by cowbirds, the negative effects of cowbirds on particular host species, and the daily patterns of cowbird behavior. ? Behavioral interactions between cowbirds and specific host species. ? Patterns of cowbird abundance and host use across varying landscapes. ? Management programs designed to control cowbirds and protect threatened songbirds. James N. M. Smith teaches at the University of British Columbia in Vancouver. Terry L.
