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.

Book Description
The story of the discovery of nearly 300 bird species new to science since 1960. Amazing as it might sound, ornithologists are still discovering several bird species each year that are completely new to science. These aren't all obscure brown birds on tiny islands – witness the bizarre Bare-faced Bulbul from Laos (2009), spectacular Araripe Manakin from Brazil (1998), or gaudy Bugun Liocichla from north-east India (2006). Birds New to Science documents more than half a century of these remarkable discoveries, covering around 300 species. Each account includes the story of discovery, a brief description of the bird (many with accompanying colour photographs), and details of what is known about its biology, range and conservation status. Written in an engaging style, this is a rich reference to an incredible era of adventure in ornithology.
