The Sandhill Cranes (Bulletin No. 29, Cranbrook Institute of Science)

Dust jacket notes: "This book is the story of one species of crane, whose four subspecies occur from western Siberia to central Cuba. The cycles of its generations, its season, its days, are fully treated. From the egg to old age the cranes have had few unwatched moments, and the author has synthesized both his own extensive observations and those of others to make this one of the most complete studies of any large bird. Today the crane populations are decreasing, owing to encroachment of agriculture on their nesting territories and the predation of many animals, including man. It is hoped that this book will help point the way to the perpetuation of the species. The book has 34 photographs and five maps. Pen studies by Francis Lee Jacques embellish the title page and cover. References to the literature are virtually complete. An appendix keys the cranes of the world."
