Book Description
A comprehensive study of Pine Crossbills. 'From mid-January to mid-April 1935 I was off on my dilapidated bicycle, but how different Speyside was from Breckland. In late February many crossbills were still in flocks; I had to walk and cycle for many miles before finding my first nest in the last week of March, when I located a small breeding group in a plantation of old pines close to a keeper's cottage. Thenceforward, until 1942, I followed the crossbills and slowly began to understand a little about them. At first everything was gloriously new. I watched my crossbills mating and discovered how subtly a winter flock changed to a mating party and from a mating party to mated groups. I studied patterns of territory and dispersion and watched how hens built their nests. I sat under trees and I climbed to nests. I watched hens brooding and saw cocks feeding them. One hen pitched on my fingers and allowed me to catch her. I still vividly recall the sharp resiny scent of her body. I saw pairs rear their young and followed them and their broods through the forest. Soon my notebooks were full, but this was only the beginning.' That extract from the book's first chapter describes how the author began his study of the Scottish pine-feeding crossbills, having noticed earlier that the calls of crossbills in Rothiemurchus Forest were different from those of the spruce-feeding common crossbills he had known in the English Breckland. From this study and a quest for the true identity of the Speyside crossbills has emerged that all too rare book, a work of scholarship and research that is wholly readable, in which the author's delight in his study subject becomes the reader's, too.

Book Description
The highly variable North American red crossbill complex has presented one of the most controversial problems in avian systematics. Although crossbills wander nomadically and breed all year, they have not become homogenized in bill and body size. This study suggests that this crossbill complex contains several distinctive sibling species that breed sympatrically and show ecological differences.

Book Description
Our purposes in this preface are, first, to reiterate our view of Current Ornithology's role; second, to describe briefly the contents of this vol ume; and third, to acknowledge the generous help of our Editorial Board and of the reviewers we have consulted about the contents of Volumes 13 and 14. As far as we know, Current Ornithology is the only English-lan guage publication currently devoted exclusively to extensive reviews and syntheses of topics pertaining to all aspects of the biology of birds. Its chapters deal with subjects falling under such diverse rubrics as ecology, evolution, behavior, phylogeny, behavioral ecology, anatomy and physiology, and conservation biology, but all focus primarily on birds. Its authors, whether members of the National Academy or young investigators just beginning their careers, are leading authorities on their subjects, and its referees are selected for their knowledge and expertise in the topics covered by the chapters they are asked to review.

Book Description
This book presents an up-to-date, detailed and thorough review of the most fascinating ecological findings of bird migration. It deals with all aspects of this absorbing subject, including the problems of navigation and vagrancy, the timing and physiological control of migration, the factors that limit their populations, and more. Author, Ian Newton, reveals the extraordinary adaptability of birds to the variable and changing conditions across the globe, including current climate change. This adventurous book places emphasis on ecological aspects, which have received only scant attention in previous publications. Overall, the book provides the most thorough and in-depth appraisal of current information available, with abundant tables, maps and diagrams, and many new insights. Written in a clear and readable style, this book appeals not only to migration researchers in the field and Ornithologists, but to anyone with an interest in this fascinating subject. * Hot ecological aspects include: various types of bird movements, including dispersal and nomadism, and how they relate to food supplies and other external conditions * Contains numerous tables, maps and diagrams, a glossary, and a bibliography of more than 2,700 references* Written by an active researcher with a distinguished career in avian ecology, including migration research

Book Description
The Canary: Natural History, Science and Cultural Significance covers the ecology, evolution and conservation of the canary and related species, along with the history and cultural significance of the domestic canary worldwide and various scientific disciplines in which canaries have played a key role as a model species. The book synthesizes the multiple ways in which the canary and its relatives have been, and continue to be, an important scientific model in diverse areas and have influenced human culture. Each chapter is written by international experts in areas such as biogeography, animal behavior, evolutionary ecology, conservation, neurobiology, genetics, or ethnology. In covering this eclectic array of topics, while always focusing on the canary and its close relatives, this book uses the immense appeal of the canary as a vehicle to present notions of ecology, evolution, biodiversity conservation, and so on, to a wide audience. Details all aspects of Crithagra and Serinus canaries as well as relatives like crossbills Structured to begin with more accessible topics like natural history, domestication, and conservation Closes with discussions of more specialized topics like evolution, neurobiology, behavior and genomics
