"Mesozoic Birds is the first book to bring together world-renowned specialists on fossil birds and their importance to avian origins and, more importantly, it stresses a unified approach (cladistics) and presents the most anatomically detailed analyses available to date. No other study or collection of studies has ever done so much. How could the project not be welcomed by its audience of paleontologists, ornithologists, and evolutionary biologists!"—David Weishampel, editor of The Dinosauria "This is the first comprehensive volume dedicated to the relationships and evolution of the birds that lived during the Age of Dinosaurs. Its wealth of information and its diversity of viewpoints will ensure that this indispensable volume is used and discussed for many years to come."—Kevin Padian, University of California, Berkeley

Depletion of fisheries due to acid rain may pose a future threat to bald eagle and osprey populations in some regions. Loss of essential habitat has affected declines in the caracara and western burrowing owl and the disappearance of the norther aplomado falcon from the southern United States. Most populations of the ferruginous hawk, marsh hawk, and prairie falcon appear stable; habitat loss is the most critical factor in population changes.

What caused the extinction of so many animals at or near the end of the Pleistocene? Was it overkill by human hunters, the result of a major climatic change or was it just a part of some massive evolutionary turnover? Questions such as these have plagued scientists for over one hundred years and are still being heatedly debated today. Quaternary Extinctions presents the latest and most comprehensive examination of these questions. ÑGeological Magazine "May be regarded as a kind of standard encyclopedia for Pleistocene vertebrate paleontology for years to come." ÑAmerican Scientist "Should be read by paleobiologists, biologists, wildlife managers, ecologists, archeologists, and anyone concerned about the ongoing extinction of plants and animals." ÑScience "Uncommonly readable and varied for watchers of paleontology and the rise of humankind." ÑScientific American "Represents a quantum leap in our knowledge of Pleistocene and Holocene palaeobiology. . . . Many volumes on our bookshelves are destined to gather dust rather than attention. But not this one." ÑNature "Two strong impressions prevail when first looking into this epic compendium. One is the judicious balance of views that range over the whole continuum between monocausal, cultural, or environmental explanations. The second is that both the data base and theoretical sophistication of the protagonists in the debate have improved by a quantum leap since 1967." ÑAmerican Anthropologist

Joseph M. Forshaw, one of the world’s leading authorities on parrots, calls attention to the threats they face: they are one of the most endangered groups of birds, with a growing number of species nearing extinction. The main threats arise from habitat loss through deforestation and agricultural development and from the taking of birds for the international live-bird trade. Vanished and Vanishing Parrots brings together information on species that have become extinct in historical times with information on species that are in danger of becoming extinct to increase public awareness of the plight of these magnificent birds. Vivid colour plates by the wildlife artist Frank Knight draw attention to the spectacular species that we have lost or that could be lost. Forshaw’s work gives us fascinating insight into these endangered and extinct parrots. Vanished and Vanishing Parrots will be a valuable reference for scientific, ornithological and avicultural organisations, as well as individual lovers of birds and of illustrated natural history books.

The landscape of southwestern Wyoming around the ghost town of Fossil is beautiful but harsh; a dry, high mountain desert with cool nights and long, cold winters inhabited by a sparse mountain desert community. But during the early Eocene, more than fifty million years ago, it was a subtropical lake, surrounded by volcanoes and forests and teeming with life. Buried within the sun-baked limestone is spectacular evidence of the lush vegetation and plentiful fauna of the ancient past, a transitional ecosystem giving us clues to how North America recovered from a great extinction event that wiped out dinosaurs and the majority of all species on the planet. Paleontologists have been conducting excavations at Fossil Butte for more than 150 years, and with The Lost World of Fossil Lake, one of the world’s leading experts on the fossils from this spectacular locality takes readers on a fascinating journey through the history of the discovery and exploration of the site. Deftly mixing incredible color photographs of the remarkable fossils uncovered at the site with an explanation of their evolutionary significance, Grande presents an unprecedented, comprehensive portrait of the site, its treasures, and what we’ve learned from them. Grande presents a broad range of fossilized organisms from Fossil Lake—from single-celled algae to palm trees to crocodiles—and together they make this long-extinct community come to life in all its diversity and splendor. A field guide and atlas round out the book, enabling readers to identify and classify the majority of the known fossils from the site. Lavishly produced in full color, The Lost World of Fossil Lake is a stunning reminder of the intellectual and physical beauty of scientific investigation—and a breathtaking window onto our planet’s long-lost past.

The flightless Mancallinae (Aves, Pan-Alcidae) from the Pacific Ocean are represented by one of the richest fossil records among Charadriiformes. A detailed review of previously published and previously undescribed fossils referred to Mancallinae resulted in taxonomic revision of the clade and the identification of three new species from the Miocene and Pliocene of California, USA. This monograph includes descriptions of new Mancallinae species and provides the first species-level phylogenetic hypothesis of Mancallinae relationships. Phylogenetic hypotheses were generated through the combined analysis of molecular sequence data and newly identified morphological character data for extant and extinct charadriiforms. The results of the combined phylogenetic analysis places hypotheses regarding the ethology and morphological convergence of Mancallinae to other flightless wing-propelled divers in phylogenetic context and facilitates comparisons between alcid paleodiversity and paleoclimatic events that have been hypothesized as drivers of alcid evolution.

A Dictionary of Birds enlists contributions from over 280 ornithologists and other specialists from around the world. Major, authoritative articles cover the field of modern ornithology and related subjects, many of them running to several thousand words. In addition there are articles on all the bird families, almost all of which are illustrated by a representative species. There are also numerous short entries defining special terms, application of names, etc. The total gives a text of over 800,000 words, supported by more than 500 photographs, drawings and diagrams. The photographs have been selected under the guidance of Eric Hosking to illustrate different activities of birds, and Robert Gillmor has assembled a collection of over 200 drawings of birds, almost all of which were specially drawn for the Dictionary. Compiled for the British Ornithologists' Union, this new work is in line of succession from Newton's A Dictionary of Birds of 1896 and Landsborough Thomson's A New Dictionary of Birds published in 1964 (2nd impression 1965) and now long out of print. This dictionary, encyclopedic in treatment, is destined to be a major reference in any ornithologist's library; and its editors and contributors, most of whom gave their time and knowledge freely, have earned the thanks and acclaim of users for many years to come.

From the discovery of the fossil Archaeopteryx to more than 10,000 different documented species today, birds have become the second most diversified class of vertebrates on Earth. Birds have evolved extensively since they first emerged in prehistoric times--but that diversity could dwindle and even vanish unless we take steps to conserve their habitats, ensuring that they sustain their numbers and their variety. This natural history of birds starts in the distant past--going back to the Jurassic, Cretaceous and Paleogene periods--in order to get a broader understanding of the birds that we see today. Chapters cover their lives, breeding, flight, migration and more, while also highlighting some especially unique bird fossils, such as the Pelagornis Sandersi, which had a wingspan of more than 20 feet. Also included are chapters on the loss of needed habitats, the current decline of native birds, and what can be done to reverse it.
