Book Description
Avian Biology, Volume II is a collection of papers that deals with the biology of birds such as their integumentary and respiratory systems. One paper describes the integument of birds that includes the skin, feathers, pterylosis, skin muscles, and other integumentary derivatives such as beaks, comb, claws, and spurs. The book explains the process of molting and the different generations of feathers; such molting is dependent on the wear and tear of the plumage, as well as hormonal changes. One author compares the blood vascular system of birds and mammals, and then gives a detailed description of avian hematology. Other papers deal with the respiratory functions, digestive system, and the nutritional needs of birds. Of interest is one author's description of the production of nutritive fluids, holocrine, which is secreted for the young. This secreted fluid contains about 23 percent protein, 10 percent fat, and no sugar. Unlike mammalian milk, it also contains cells. Another paper examines the intermediary metabolism of birds and the climatic effects on metabolism. This book is suitable for bird enthusiasts, zoologists, and avian biologists.

Book Description
The essential text for ornithology courses, this book will leave students with a lifelong understanding and appreciation of the biology and ecology of birds. Aves, the birds, is the wildlife group that people most frequently encounter. With over 10,000 species worldwide, these animals are part of our everyday experience. They are also the focus of intense research, and their management and conservation is a subject of considerable effort throughout the world. But what are the defining attributes that make a bird a bird? Aimed at undergraduate and graduate students, Ornithology provides a solid modern foundation for understanding the life and development of birds. Written by renowned experts from around the globe, this comprehensive textbook draws on the latest research to create an innovative learning experience. Moving beyond bones, muscle, and feathers, it provides the core information needed to “build” the bird, linking anatomy and physiology with ecology and behavior. As it reviews the major orders of birds, the book highlights their wide diversity and critically evaluates ornithological concepts and theories. Incorporating brief biographies of leaders in the field, the text describes their contributions in the context of key historical events in bird science. Each chapter ends with a summary of the material covered, a discussion of potential management and conservation applications, and suggested study questions that will stimulate thought and discussion.
