Download or read book Avian Biology written by Donald S. Farner and published by Elsevier. This book was released on 2013-09-17 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ornithology written by Michael L. Morrison and published by JHU Press. This book was released on 2018-09-03 with total page 1017 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sunbirds written by Clive F. Mann and published by A&C Black. This book was released on 2010-07-30 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sunbirds is the first book since the 19th Century to cover in detail all the world's sunbirds and spiderhunters - the Nectarinidae. It also includes the allied families of flowerpeckers and sugarbirds; a total of 176 species is described and illustrated. The book has been designed to help readers identify all of these species and also their various subspecies, the most distinctive of which are illustrated as well as described. Each species account provides a distribution map, a summary of identification criteria and a description of how the species differs from similar ones. The calls and songs, habitat, geographical distribution, status, movements, food (including a list of known food plants), habits, and breeding biology are also described. Finally, a full description of the species and salient features of each subspecies is given, together with measurements and references. Sunbirds not only aids identification, it provides a wealth of information on the ecology and behaviour of these birds. The authors have carried out extensive fieldwork in Asia and Africa. They have also studied skins, nests and eggs held by museums, analysed tape recordings and critically reviewed the vast amount of material contained in books and scientific journals. The superb plates would not have been possible without the exhaustive study of specimens which, together with the use of photographs of living birds, has resulted in the artist, Richard Allen, capturing the essence of the birds, their 'jizz', and accurately portraying the beautiful, bright, often iridescent, plumages of these spectacular families.
