Manual of Ornithology

"Here is a volume that has no parallel. . . . A good reference book for those interested in the details of avian anatomy."--Science Books & Films "A gold mine of facts. . . . Every library and biology department, as well as every birder, should have a copy close at hand."--Roger Tory Peterson, from the foreword One of the most heavily illustrated ornithology references ever written, Manual or Ornithology is a visual guide to the structure and anatomy of birds--a basic tool for investigation for anyone curious about the fascinating world of birds. A concise atlas of anatomy, it contains more than 200 specially prepared accurate and clear drawings that include material never illustrated before. The text is as informative as the drawings; written at a level appropriate to undergraduate students and to bird lovers in general, it discusses why birds look and act the way they do. Designed to supplement a basic ornithology textbook, the Manual of Ornithology covers systematics and evolution, topography, feathers and flight, the skeleton and musculature, and the digestive, circulatory, respiratory, excretory, reproductive, sensory, and nervous systems of birds, as well as field techniques for watching and studying birds. Each chapter concludes with a list of key references for the topic covered, with a comprehensive bibliography at the end of the volume.
