Birds are among the most extensively studied of all animal groups. Hundreds of academic journals and thousands of scientists are devoted to bird research, while amateur enthusiasts (called birdwatchers or, more commonly, birders) probably number in the millions. Birds are categorised as a biological class, Aves. The earliest known species of this class is Archaeopteryx lithographica, from the Late Jurassic period. According to the most recent consensus, Aves and a sister group, the order Crocodilia, together form a group of unnamed rank, the Archosauria. Phylogenetically, Aves is usually defined as all descendants of the most recent common ancestor of modern birds (or of a specific modern bird species like Passer domesticus), and Archaeopteryx. Modern phylogenies place birds in the dinosaur clade Theropoda. Modern birds are divided into two superorders, the Paleognathae (mostly flightless birds like ostriches), and the wildly diverse Neognathae, containing all other birds.

This book represents a complete revision of the authors' previous authoritative work. It incorporates all the significant changes to bird taxonomy that have occurred over the past six years and remains the only single-volume work to list subspecies. Ornithologists are constantly reviewing and revising the scientific and common names of the world's birds--combining and dividing established species and genera. Despite the fact that opinions will continue to vary on the details of avian classification, lists such as this provide a baseline reference to scientific and English names, taxonomy, and distribution for both the professional and amateur ornithologist and taxonomist. In the next decade, new studies using advanced groupings may establish new systematic groupings. The current list, by adding to and amending the classic listing of Peters and his successors, may well be the last and most finely developed list in the traditional mold and, therefore, a prime reference for years to come. Key Features * The most up to date list of the world's birds * Covers their distribution using traditional taxonomy * The only single-volume reference to include subspecies * Lists approximately 9,200 species and their subspecies * Thoroughly revised and updated

The Wonderful World of Birds - How to Make Friends With Our Feathered Friends Table of Contents Introduction Knowing More about the Birds around You – Fun Facts of the More Common Bird Species Blackbirds Sparrows Hawks Cranes Goldfinch Ducks Blue Jays Chickadees Egrets Vultures Falcons Gulls Finches Owls The Territorial Rights of Birds How to Make Bird Houses Different Styles of Bird Houses Special Birdhouse Plans for Different Bird Species Taking Care of Your Bird Pets Feeding Your Feathered Friends Starting A Bird Watching Club Conclusion Introduction Did you know that some of the birds which people believed would never ever be extinct because they were so numerous have disappeared in the 20th and the 21st century? The last passenger pigeon, which once covered the skies of North America, died in captivity in 1904. In the same manner, it took just five years to kill off all the vultures, the Kites, the Eagles and the house sparrow (Passer Domesticus) and many other birds once common in cities, in parts of the Indian subcontinent. Blame it all on pesticides and also humans encroaching the natural habitats of birds. So why should you be interested in the wonderful world of birds, you may ask? Well, it is a well-known fact that a number of bird species are disappearing from the face of the earth, just like the Great Auk and the dodo at the rate of 10- 25 per year. So what, you may say, after all, there are so many other birds to choose from. Just calculate. 25 species going extinct per year, never to make their appearance on earth again. At this rate, we are not going to see a living bird in the next 50 to 75 years. That is reality. There may come a generation, which may ask its grandparents, “what were those silly little creatures, you called birds? We can just hear their songs on audio. What were they like to look at?” And the grandparents trying desperately to describe the magic world of birds. Imagine a world without nightingales singing in Berkeley Square, bluebirds flying over the white cliffs of Dover, peacocks in purple adorning and other such songbirds disappearing from your windowsill, garden and lives. Imagine no bird nesting in your garden or waking you up to birdsong, bright and early in the morning. So if you begin to take an interest in birds, there is a chance that you may want to help save them and your children might grow up to be keen ornithologists.

Birds in the Ancient World from A to Z gathers together the ancient information available, listing all the names that ancient Greeks gave their birds and all their descriptions and analyses. W. Geoffrey Arnott identifies as many of them as possible in the light of modern ornithological studies. The ancient Greek bird names are transliterated into English script, and all that the ancients said about birds is presented in English. This book is accordingly the first complete discussion of ancient bird names that will be accessible to readers without ancient Greek. The only large-scale examination of ancient birds for seventy years, the book has an exhaustive bibliography (partly classical scholarship and partly ornithological) to encourage further study, and provides students and ornithologists with the definitive study of ancient birds.

Turkey is a popular destination for birders and tourists, and although there has been much published on its birds over the past 40 years, there has never been a comprehensive avifauna. The Birds of Turkey redresses this. It contains a detailed account of every species on the Turkish list, with a full breakdown of records and status, distribution in Turkey, and taxonomy. There are also authoritative introductory chapters on geography, climate, habitats, history of ornithology and conservation.

This book looks at the world's naturalised (successfully introduced) species of bird. Many species have been introduced to countries outside their natural range by people, either deliberately or accidentally, with varied consequences for both those species themselves and the native fauna of their 'new' homes. In Britain, the introduced Canada Goose has quickly become ubiquitous at every lake and riverside, while the Golden Pheasant remains a scarce and unobtrusive inhabitant of a few scattered, remote woodlands. The House Sparrow and Common Starling, both in decline over parts of their native range, are thriving in a naturalised state in North America and elsewhere in the world. Naturalised populations of Mallard in various parts of the world are threatening a total of seven other duck species with extinction through hybridisation. This book discusses each species in turn, describing how, why, when and where its introduction took place, how it became established, and the ecological and economic impacts its presence has had in the country or countries it is naturalised in. Each account has a map, showing natural and introduced range, and there is a wealth of beautiful line drawings of the species concerned.
