Download or read book Social Behaviour in Animals written by J. Tinbergen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: HIS book is not intended as an exhaustive review T of facts. Its aim is rather the presentation of a bio logical approach to the phenomena of social behaviour. This type of approach was revived by Lorenz's pioneer studies. It is characterized by emphasis on the need for renewed and careful observation of the huge variety of social phenomena occurring in nature; by emphasis on a balanced study of the three main biological problems function, causation, evolution; by emphasis on an appro priate sequence of description, qualitative analysis, quanti tative analysis; and finally by emphasis on the need for continuous re-synthesis. The character of this approach, combined with the limitations of space, have determined this book's contents. Limits of space led to the omission of a great deal of de scrip tion. Thus, Deegener's voluminous work on fhe multitude of types of animal aggregations has not been discussed. Also, the highly specialized 'states' of social insects have not been treated in detail, since there are excellent books dealing exclusively with them.

Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1953, this is a classic study in animal behaviour, drawing on the author’s own extraordinary studies of insects, fish, and birds, as well as on the literature. The concept ‘community’ is taken in its widest sense to include all types of association of individuals, not only flocks and herds, but also the family, the pair, and even two animals engaged in combat. The author received the Nobel Prize for his work in this field in 1973.

Download or read book Flight Lines written by Andrew Darby and published by Simon and Schuster. This book was released on 2020-11-03 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: A trans-world journey with an extraorindary shorebird—from Australia's southern ocean to the Arctic and back—that explores the mysteries of the natural world and its power to heal. As the sun lowered and turned Gulf St Vincent fiery, they each called a high-pitched 'peeooowiii!', flashed their black wing-pits, spread their tail skirts and took flight... In a luminous new boook, Andrew Darby follows the odysseys of two seemingly-humble Grey Plovers, little-known migratory shorebirds, as they take previously uncharted ultramarathon flights from the southern coast of Australia to Arctic breeding grounds. On these death-defying flights they dodge predators, typhoons, exhaustion, and countless other dangers before they can breed...and then survive the jrouney all over again and return south to their feeding grounds. But the greatest threat to these, and other long-distance migrants on the flyway, is China's "dragon economy," which is engulfing their vital Yellow Sea staging spots. In Flight Lines, we meet the dedicated people of all nationalities and backgrounds working to save these intrepid birds, from Russia to Alaska, from the rim of the Arctic Sea to the coasts of the Southern Ocean. Out of their hard-won science Darby finds hope for the birds—an unexpected bright light for our times. But his journey to understand these marvellous birds almost ends when he is suddenly diagnosed with an incurable cancer. Then he finds science coming to his rescue too, as his own story and the journey of these little birds intersect in an unexpected and beautiful way.

Download or read book Man and Wildfowl written by Janet Kear and published by A&C Black. This book was released on 2010-11-30 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The involvement of humans with ducks, geese and swans has probably been closer than with any other group of birds, today and for several millenia past. This involvement, in its many aspects, is the theme of this compelling and readable account by an Assistant Director of the Wildfowl and Wetlands Trust. Dr Kear ranges widely, from a summary of the taxonomy and natural history of wildfowl, through a history of domestication world wide, to wildfowling, decoys, conservation and captive breeding, conflicts with agriculture, and wildfowl in legend and literature. Throughout, the text abounds with little-known facts and insights to intrigue the general reader and expert alike - a reflection of the author's wide reading and affection for her subject.
