Book Description
Drawing on the knowledge and insight gained from a lifetime of watching, studying, and enjoying birds, this book is full of information about more than four hundred species of birds in Texas, most all of which author Gary Clark has seen first hand. Organized in the standard taxonomic order familiar to most birders, the book is written in a conversational tone that yields a wide-ranging discussion of each bird’s life history as well as an intimate look at some of its special characteristics and habits. Information regarding each species’ diet, voice, and nest is included as well as when and where it can be found in Texas. Magnificent photographs by Kathy Adams Clark accompany each bird’s entry. For those just beginning to watch birds to those who can fully relate to the experiences and sentiments communicated here by a veteran birder, this book reveals the kind of personal connection to nature that careful attention to the birds around us can inspire.

Book Description
Ten years have passed since the first edition of this book. During that time the field of bird migration has experienced many advances which are reflected in this second edition. No other book exists to bring together the vast amount of information currently available on the subject of bird migration. Includes discussion of evolution and history of bird migration, physiology, orientation mechanisms and threats to migrations and is accessible to experts as well as amateurs.

Book Description
This is the first book to summarize the methods, conceptual issues and results of studies using the interpretation of feather growth rates as an index of nutritional condition in birds. The author has coined the term ptilochronology (literally, 'the study of feather time') to describe this technique, which relies on the fact that as a feather grows it produces visible growth bars. Both the technique and its conceptual foundations have been applied worldwide to numerous studies ofavian evolution, ecology, and conservation biology. The author reviews this work, chronicles the various criticisms that have been made, and describes how these have influenced the development of ptilochronology. He goes on to suggest experimental methodologies and analytical techniques to safeguardagainst invalid results. A final chapter summarises this new technique's contribution to avian biology, and suggests potential applications and a future research agenda. An appendix details specific measurements and describes the methodology associated with ptilochronology.Ptilochronology provides a practical resource as well as a conceptual understanding of how this technique can be used to address important questions in avian biology. It will be of relevance and use to professional avian biologists and ornithologists as well as to graduate students of avian behavioural ecology, evolution and conservation.

Book Description
Some birds mate for life, while others have many partners. Why? In this book, fourteen classic studies of bird behaviour are brought together to compare the different partnership patterns from ecological and evolutionary perspectives. Often there is a battle of the sexes, as individual birds behave in the way that serves their best interests. Introductory and concluding chapters review the latest thinking on this fascinating subject. - ;Some birds mate for life, while others have many partners. In this book, fourteen studies are brought together to compare different partnership patterns from ecological and evolutionary perspectives. The subjects have been chosen to include the same species living in different habitats (Sparrowhawks) and at different population densities (Great Tits). There are comparisons between closely related species (Mute Swans and Bewick's Swans). The studies span the globe and the behavioural gradient, from Iceland's strictly monogamous Whooper Swans to Australia's sexually promiscuous Splendid Fairy-wrens. In all cases, sexual and social relationships strongly influence a bird's survival and breeding success. -

Book Description
How birds have evolved and adapted to survive winter Birds in Winter is the first book devoted to the ecology and behavior of birds during this most challenging season. Birds remaining in regions with cold weather must cope with much shorter days to find food and shelter even as they need to avoid predators and stay warm through the long nights, while migrants to the tropics must fit into very different ecosystems and communities of resident birds. Roger Pasquier explores how winter affects birds’ lives all through the year, starting in late summer, when some begin caching food to retrieve months later and others form social groups lasting into the next spring. During winter some birds are already pairing up for the following breeding season, so health through the winter contributes to nesting success. Today, rapidly advancing technologies are enabling scientists to track individual birds through their daily and annual movements at home and across oceans and hemispheres, revealing new and unexpected information about their lives and interactions. But, as Birds in Winter shows, much is visible to any interested observer. Pasquier describes the season’s distinct conservation challenges for birds that winter where they have bred and for migrants to distant regions. Finally, global warming is altering the nature of winter itself. Whether birds that have evolved over millennia to survive this season can now adjust to a rapidly changing climate is a problem all people who enjoy watching them must consider. Filled with elegant line drawings by artist and illustrator Margaret La Farge, Birds in Winter describes how winter influences the lives of birds from the poles to the equator.

Book Description
Few capitals in the world are blessed with such rich and varied bird-life as Delhi. While these avian visitors and residents have always fascinated the people of this city, it is during the past few years that birdwatching has become a popular hobby among the young and old alike. In this book, the author profiles over 150 species of birds, inviting readers from all walks of life to join him in uncovering some of the city's most precious avian wonders-be it birds that visit your garden, or those you see in the city's parks and woodlands; the huge rafts of wildfowl and other water-birds on the Jamuna and nearby water-bodies, or the mysterious flocks that arrive and depart during the year. Also of use to those interested is information on what each of these birds looks like, where and when they can be found, what they eat, whether or when they breed or visit Delhi, and more. The book also introduces readers to various birding areas in and around Delhi, and highlights the bird life found there. Familiar areas include the Yamuna, Okhla, Tughlaquabad, the Ridge, the Asola Sanctuary, Sultanpur National Park, Badhkal Lake, as well as some of Delhi's parks and green area: Lodhi Garens, Buddha Jayanti Park, Deer Park, Qudsia Gardens, and the National Zoological Park, to name a few. The 50 color plates in the text comprise photographs of birds encountered by the author in the course of his many birdwatching expeditions. While some photographs capture rare species, others of birds more familiar to us, are no less fascinating.
