Famous for their size and elegance in flight, albatrosses are familiar to anyone who has travelled through the southern oceans, and are a flagship family of conservation concern. However, albatrosses are just one of several groups of 'pelagic' birds - those that visit land only to breed, and spend the rest of their lives far from the coast, soaring from ocean to ocean in a never-ending search for food. Mysterious and graceful, these birds can present a formidable identification challenge to even the most experienced birder. This fixed-format ebook provides the answer - the first comprehensive guide to pelagic birds, the albatrosses, petrels, shearwaters, storm-petrels and diving petrels. Optimised for iPad, it features the book in crisp, clear high-resolution. A total of 46 detailed, fully zoomable colour plates highlight key ID criteria of the birds in flight, with close-ups of diagnostic regions of the plumage. The plates are accompanied by accurate distribution maps, while the sparkling text brings the world of these amazing birds to life. Sea-watchers all around the world will find this superb field guide indispensable – and no birder will want to be without it.

Petrels, albatrosses, and storm-petrels are among the most beautiful yet least known of all the world's birds, living their lives at sea far from the sight of most people. Largely colored in shades of gray, black, and white, these enigmatic and fast-flying seabirds can be hard to differentiate, particularly from a moving boat. Useful worldwide, not just in North America, this photographic guide is based on unrivaled field experience and combines insightful text and hundreds of full-color images to help you identify these remarkable birds. The first book of its kind, this guide features an introduction that explains ocean habitats and the latest developments in taxonomy. Detailed species accounts describe key identification features such as flight manner, plumage variation related to age and molt, seasonal occurrence patterns, and migration routes. Species accounts are arranged into groups helpful for field identification, and an overview of unique identification challenges is provided for each group. The guide also includes distribution maps for regularly occurring species as well as a bibliography, glossary, and appendixes. The first state-of-the-art photographic guide to these enigmatic seabirds Includes hundreds of full-color photos throughout Features detailed species accounts that describe flight, plumage, distribution, and more Provides overviews of ocean habitats, taxonomy, and conservation Offers tips on how to observe and identify birds at sea

In this fifteenth edition of State of the World, Lester R. Brown and the Worldwatch research team look at the environmental effects of continuing economic growth as the economy outgrows the earth's ecosystem. As the global economy has expanded from $5 trillion of output in 1950 to $29 trillion in 1997, its demands have crossed many of the earth's sustainable yield thresholds

The extent to which human activity has influenced species extinctions during the recent prehistoric past remains controversial due to other factors such as climatic fluctuations and a general lack of data. However, the Holocene (the geological interval spanning the last 11,500 years from the end of the last glaciation) has witnessed massive levels of extinctions that have continued into the modern historical era, but in a context of only relatively minor climatic fluctuations. This makes a detailed consideration of these extinctions a useful system for investigating the impacts of human activity over time. Holocene Extinctions describes and analyses the range of global extinction events which have occurred during this key time period, as well as their relationship to both earlier and ongoing species losses. By integrating information from fields as diverse as zoology, ecology, palaeontology, archaeology and geography, and by incorporating data from a broad range of taxonomic groups and ecosystems, this novel text provides a fascinating insight into human impacts on global extinction rates, both past and present. This truly interdisciplinary book is suitable for both graduate students and researchers in these varied fields. It will also be of value and use to policy-makers and conservation professionals since it provides valuable guidance on how to apply lessons from the past to prevent future biodiversity loss and inform modern conservation planning.
