This is the first book created primarily for the field identification of parrots, one of the most familiar and colorful groups of birds. From the mighty. macaws to the diminutive pygmy parrots, the 350 species of parrots include cockatoos, parakeets, lovebirds, and Budgerigar. Most are brightly colored or even gaudy, but a few are drab, and some are nocturnal and flightess. Parrots, found throughout most of the warmer regions of the world, occur in greatest numbers in Australasian and South America. This book includes 88 superb color illustrations of every species and most identifiable subspecies of parrot, as well as range maps of their locations. It offers many firsthand insights into the ecology of each species, vocalizations, life cycle characteristics, and geographical variation. It also provides up-to-date information on the conservation status of those species of parrots that are threatened or endangered.

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.

Forestry professors used to remind students that, whereas physicians bury their mistakes, foresters die before theirs are noticed. But good institutions live longer than the scientists who contribute to building them, and the half-century of work of the USDA Forest Service's Institute of Tropical Forestry (ITF) is in plain view: an unprecedented corpus of accomplishments that would instill pride in any organization. There is scarcely anyone interested in current issues of tropical forestry who would not benefit from a refresher course in ITF's findings: its early collaboration with farmers to establish plantations, its successes in what we now call social forestry, its continuous improvement of nursery practices, its screening trials of native species, its development of wood-processing technologies appropriate for developing countries, its thorough analysis of tropical forest function, and its holistic approach toward conservation of endangered species. Fortunately, ITF has a long history of information exchange through teaching; like many others, I got my own start in tropical forest ecology fromjust such a course in Puerto Rico. And long before politicians recognized the global importance of tropical forestry, the ITF staff served actively as ambassadors of the discipline, visiting tropical coun tries everywhere to learn and, when invited to do so, to help solve local problems. It is a general principle of biogeography that species' turnover rates on islands are higher than those on continents. Inevitably, the same is true of scientists assigned to work on islands.

Concerned conservationists and professional and amateur ornithologists alike welcomed the inauguration, in 1983, of Bird Conservation. Sponsored by the U.S. Section of the International Council for Bird Preservation, the ambitious project was designed to provide a yearly overview of current research and key ecological topics in the field of bird conservation. This, the second yearbook of the series, includes essays by leading ecologists and ornithologists and focuses on a range of issues critical to island birds--among them, the status of endangered birds of Micronesia, the distribution and abundance of Hawaiian native birds, the vulnerability of endemic island birds to extinction, and bird conservation efforts in the United States Caribbean. Also included are concise reports on recent bird conservation activities and research and an annotated bibliography of relevant literature.

This book explains how to foresee and manage ecosystem changes in the Luquillo Mountains in Puerto Rico, by looking at underlying causes and effects. The lessons from the abiotic and biotic environments, populations, and ecosystems in this region apply to analogous forest biomes in Central and South America, as well as around the world.
