The feathery tribe : Robert Ridgway and the modern study of birds
\"Amateurs and professionals studying birds at the end of the nineteenth century were a contentious, passionate group with goals that intersected, collided and occasionally merged in their writings and organizations. Driven by a desire to advance science, as well as by ego, pride, honor, insecurity, religion and other clashing sensibilities, they struggled to absorb the implications of evolution after Darwin. In the process, they dramatically reshaped the study of birds. Daniel Lewis here explores the professionalization of ornithology through one of its key figures: Robert Ridgway, the Smithsonian Institution's first curator of birds and one of North America's most important natural scientists. Exploring a world in which the uses of language, classification and accountability between amateurs and professionals played essential roles, Lewis offers a vivid introduction to Ridgway and shows how his work fundamentally influenced the direction of American and international ornithology. He explores the inner workings of the Smithsonian and the role of collectors working in the field and reveals previously unknown details of the ornithological journal The Auk and the untold story of the color dictionaries for which Ridgway is known\"-- Provided by publisher.
Ospreys
A fascinating look at one of the greatest conservation success stories of the modern era: the wildly popular, unique, and thrilling raptor, the Osprey. Ospreys are one of the few bird species that are found throughout the world. From forests in Hokkaido to rivers in Oregon and islands off Australia, Ospreys steal the show as nature lovers easily watch them build their massive nests and tend to their young. The fact that the Osprey is one of the few large birds that can hover adds to its mystique, and to watch it plunge into the water, emerging with a fish clutched in its talons, is truly a sight one will remember. As widespread as Ospreys are, not long ago they were under threat of extinction. During the 1950s and '60s, scientists tied the decline of Osprey populations to the heavy use of DDT and other human pollutants. In the 1980s, Ospreys began a slow recovery due to the efforts of conservationists and through the resilience of the adaptable raptors themselves. Today they are again considered common in most parts of the world, although some populations remain threatened. In this gorgeously illustrated book, Alan F. Poole, one of America's premier Osprey experts, has written a lyrical exposé of these majestic creatures, describing their daily habits and exploring their relationship with the environment. Ospreys celebrates the species' miraculous recovery from contaminants and hunters, chronicles their spectacular long-distance migrations, and unveils their vital role in bringing life to coastal habitats. Few other birds have such a hold on the human imagination. This book shows us why.
The Individual Travel Cost Method with Consumer-Specific Values of Travel Time Savings
The treatment of the opportunity cost of travel time in travel cost models has been an area of research interest for many decades. Our analysis develops a methodology to combine the travel distance and travel time data with respondent-specific estimates of the value of travel time savings (VTTS). The individual VTTS are elicited with the use of discrete choice stated preference methods. The travel time valuation procedure is integrated into the travel cost valuation exercise to create a two-equation structural model of site valuation. Since the travel time equation of the structural model incorporates individual preference heterogeneity, the full structure model provides a travel cost site demand model based upon individualized values of time. The methodology is illustrated in a study of recreational birdwatching, more specifically, visits to a ‘stork village’ in Poland. We show that the usual practice of basing respondents’ VTTS on 1/3 of their wage rate is largely unfounded and propose alternatives—including a separate component of the travel cost survey aimed at valuation of respondents’ VTTS or, as a second best, asking if they wish if their journey was shorter and for those who do—use full hourly wage as an indicator of their VTTS.
migration ecology of birds
This book presents an up-to-date, detailed and thorough review of the most fascinating ecological findings of bird migration.

Human Actions Alter Tidal Marsh Seascapes and the Provision of Ecosystem Services
Tidal marshes are a key component of coastal seascape mosaics that support a suite of socially and economically valuable ecosystem services, including recreational opportunities (e.g., fishing, birdwatching), habitat for fisheries species, improved water quality, and shoreline protection. The capacity for tidal marshes to support these services is, however, threatened by increasingly widespread human impacts that reduce the extent and condition of tidal marshes across multiple spatial scales and that vary substantially through time. Climate change causes species redistribution at continental scales, changes in weather patterns (e.g., rainfall), and a worsening of the effect of coastal squeeze through sea level rise. Simultaneously, the effects of urbanization such as habitat loss, eutrophication, fishing, and the spread of invasive species interact with each other, and with climate change, to fundamentally change the structure and functioning of tidal marshes and their food webs. These changes affect tidal marshes at local scales through changes in plant community composition, complexity, and condition and at regional scales through changes in habitat extent, configuration, and connectivity. However, research into the full effects of these multi-scaled, interactive stressors on ecosystem service provision in tidal marshes is in its infancy and is somewhat geographically restricted. This hinders our capacity to quickly and effectively curb loss and degradation of both tidal marshes and the services they deliver with targeted management actions. We highlight ten priority research questions seeking to quantify the consequences and scales of human impacts on tidal marshes that should be answered to improve management and restoration plans.
