Book Description
'This long-awaited update to the acclaimed first edition is the definitive guide to a complex and intriguing family. The species accounts and taxonomic treatments have been fully revised in line with recent studies, and the all-new plates and photos complete this remarkable work. Highly recommended.' – Dominic Mitchell Beautiful, colourful, often fearless hunters of large insects and small vertebrates, shrikes are among the most admired of all avian groups. The group is widespread (particularly in the Old World) with a large number of species, though many populations have plummeted in recent years, especially in Europe. This is a second edition of Norbert Lefranc's Shrikes, fully updated from its 1997 predecessor. The introductory texts have been significantly expanded and six new sections have been added in the species accounts: vagrancy, foraging behaviour, breeding success, population trends, conservation and taxonomic notes. Special attention has been given to the latest developments in shrike systematics, not forgotten by the DNA revolution. The species accounts give information about the past and current distribution, along with threats and conservation status. Detailed and fully revised maps accompany the authoritative text, along with hundreds of high-quality photos showcasing racial and ageing differences as well as interesting aspects of shrike behaviour. An exceptional new series of plates by Tim Worfolk have been created, with more individual plumages shown than in the previous edition. This beautiful book represents the definitive account of shrikes and their relationships, appearance, conservation and lifestyle; it will be treasured by birdwatchers and professional ornithologists alike.

Book Description
Ornithology in Laboratory and Field is intended as an aid to ornithological study at the college or university level. Students who lack the background knowledge usually acquired during a course in general zoology or biology should keep it handy for ready reference a standard elementary text on the subject. This book contains extensive material for purely informational reading, possibly enough to supplant the need of an additional textbook. Its principal purpose still complies with the title of its predecessors for it is essentially a manual to guide and assist the student in direct observations. All twenty sections, except the last (""The Origin, Evolution, and Decrease of Birds""), suggest methods and provide instructions for studies; and all conclude with an extensive list of references, frequently annotated, for further information. The twenty sections of the book can be taken up in almost any order and some may be omitted without affecting the instructional value of the others. A feature of this new edition is an introduction to birds and ornithology, intended for reading at the beginning of a course. The purpose is twofold: to show the significance of birds for study and to give an overall preview of ornithology, the subject, with emphasis on its wide scope, how it is studied, and some of the continuing and exciting opportunities that it offers for investigation.
