Wetland birds provide us with some of nature's most wonderful sights--from vast flocks soaring overhead to newly-hatched chicks drying in the sun. Apart from their beauty and recreational and economic importance, these birds are excellent indicators of water quality and measures of biodiversity. But how do they use wetland habitats, and how can we best conserve and maintain them for the future? Milton Weller describes the ecology of wetland birds by identifying patterns of habitat use and typical bird communities that result from the use of resources such as food, cover, and breeding sites. He integrates basic and practical information on bird/habitat relationships for researchers, landowners, managers, and avid birders alike. As wetlands continue to decline, this book will help us to understand the potential and limits of wetlands as bird habitats.
"Freshwater Marshes "was first published in 1994. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. Prairie potholes, wetland edges of lakes and rivers, and other freshwater marshes play a vital role in maintaining a clean and plentiful water supply for wildlife and human use. These wetland areas provide habitat for spawning fish, feed waterfowl, purify and retain water, and control erosion. In this updated third edition, Milton W. Weller describes the components of the freshwater marsh: its annual and seasonal dynamics as affected by rainfall cycles and the plant and animal population's response to such changes. Weller discusses how such wetland areas are managed for wildlife populations and diversity, and how such processes can be used in wetland conservation and restoration. He considers the impact society has on wetlands and offers conservation goals for freshwater wetland complexes. Weller broadens the third edition to include an analysis of how prairie wetlands compare in water dynamics with swamps, tidal marshes, and other wetlands. He also expands the discussion of wetland classification, evaluation, mitigation, and restoration, and introduces a new glossary of current wetland terminology. "Freshwater Marshes " is Volume 1 of Wildlife Habitats. Milton W. Weller is professor emeritus and former Kleberg Chair in Wildlife Ecology, at Texas A&M University.
"Waterfowl in Winter "was first published in 1988. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. The emphasis in research on waterfowl has traditionally focused on breeding as opposed to migrant or wintering birds. Scientists have long been interested in courtship, nest sites, laying, and brood-rearing, and they have also been concerned about losses of eggs, young, nesting hens, and breeding habitats, especially as they have affected the goal of increasing populations. But lately there has been an upsurge of interest and research on the migratory and wintering phases, and this volume offers ample evidence of the knowledge gained. The authors--105 waterfowl biologists--have contributed 47 chapters that range geographically from Alaska to northern South America, and from the Pacific Northwest to Nova Scotia and Florida. Their subjects include: distributional changes due to human influence; population trends and concerns over less common species; pairing and other behavior that occurs in the wintering areas and is vital to the success of the species; feeding ecology and body condition during winter; new habitats created by such activities as aquaculture and park development; losses of habitat due to development and drainage for alternate uses; lead poisoning and pollutants that are detrimental to waterfowl; habitat management for maintenance of successful populations now and in the future. Also presented are reports of workshop discussions outlining current issues and future research needs. Preparation of this volume was assisted by an editorial board comprising Bruce J. J. Batt, Robert H. Chabreck, Leigh H. Fredrickson, and Dennis G. Raveling.
