Book Description
"The Iowa Breeding Bird Atlas"—the first comprehensive statewide survey of Iowa's breeding birds—provides a detailed record of the composition and distribution of the avifauna of the Hawkeye State. The atlas documents the presence of 199 species, 158 of which were confirmed breeding. This landmark volume will alert Iowans to the limited distribution of numerous species and serve as a guide to the management practices—such as forest and wetland management, set-aside programs, reduction in farm chemical use, and crop diversity—which could help insure that many future changes are positive ones. "The Iowa Breeding Bird Atlas" provides a welcome and much-needed baseline for future comparisons of changes in Iowa's birdlife and, by extension, the lives of all animals in the state.

Book Description
Much has changed with Iowa’s wildlife in the years 1990 to 2020. Some species such as Canada goose, wild turkey, and white-tailed deer that once were rare in Iowa are now common, and others like sandhill crane, river otter, and trumpeter swan are becoming increasingly abundant. Iowa’s Changing Wildlife provides an up-to-date, scientifically based summary of changes in the distribution, status, conservation needs, and future prospects of about sixty species of Iowa’s birds and mammals whose populations have increased or decreased in the past three decades. Readers will learn more about familiar species, become acquainted with the status of less familiar species, and find out how many of the species around them have fared during this era of transformation.

Book Description
"The Kansas Breeding Bird Atlas represents the efforts of 180 volunteers who diligently sought out birds over a period of six years, observing their behavior and locating active nests and fledged young throughout the state, whether in tallgrass prairies, riparian forests, or wetlands. In addition to these efforts, Busby and Zimmerman gathered a wealth of information relating the volunteers' observations to ecological factors affecting the birds' habitat selection.".

Book Description
No bird is common, if we use “common” to mean ordinary. But birds that are seen more commonly than others can seem less noteworthy than species that are rarely glimpsed. In this gathering of essays and illustrations celebrating fifty of the most common birds of the Upper Midwest, illustrator Dana Gardner and writer Nancy Overcott encourage us to take a closer look at these familiar birds with renewed appreciation for their not-so-ordinary beauty and lifeways.Beginning with the garishly colored male and the more gently colored female wood duck, whose tree cavity nest serves as a launching pad for ducklings in the summer months, and ending on a bright yellow note with the American goldfinch, whose cheerful presence enlivens the midwestern landscape all year long, Overcott combines field observations drawn from her twenty-plus years of living and birding in Minnesota's Big Woods with anecdotes and data from other ornithologists to portray each species' life cycle, its vocalizations and appearance, and its habitat, food, and foraging methods as well as migration patterns and distribution. Infused with a dedication to conserving natural resources, her succinct yet personable prose forms an ideal complement to Gardner's watercolors as this renowned illustrator of avian life worldwide revisits the birds of his childhood. Together art and text ensure that the wild turkey, great blue heron, sharp-shinned hawk, barred owl, pileated woodpecker, house wren, ovenbird, field sparrow, rose-breasted grosbeak, red-winged blackbird, and forty other species of the Upper Midwest are never seen as common again.

Book Description
"Johnsgard provides an overview of the history, current status, and uncertain future of prairie birds, from falcons and shorebirds to larks and sparrows. Some are intercontinental migrants that winter in South America, others sedentary species or short-distance travelers that may frequent the grasslands of Mexico. Johnsgard describes each species - its features, habits, habitats, migratory patterns, and breeding season ecology.".

Book Description
Nutrients from farms in the Mississippi River Basin are the leading cause of the Gulf of Mexico‘s 'Dead Zone,' a 5,000 to 7,000 square mile region where declining oxygen levels are threatening the survival of marine life. From the Corn Belt to the Gulf explores how new agricultural policy can help alleviate this problem, and at the same time improve water quality overall, enhance biodiversity, improve the quality of life for the people who live and work in Corn Belt communities, and relieve downstream flooding. The themes of the book are the far-reaching environmental impacts of Corn Belt agriculture, including associated economic and social effects at multiple spatial scales - and the potential for future agricultural policy to address those impacts through changes in agricultural landscapes and practices. We know that the environmental 'footprint' of Corn Belt agriculture extends beyond farmland and adjacent lakes and streams to groundwater, rivers, cities downstream, into the Gulf of Mexico, and, ultimately, to global oceanic and atmospheric systems. And we acknowledge that agricultural policies, including commodity support payments, have economic impacts at the national and international levels. Pressing negotiations with America‘s trade partners, along with increasing societal attention to both the costs and environmental effects of current agricultural policy, are creating momentum for policy change. From the Corn Belt to the Gulf presents innovative, integrated assessments of the agriculture and ecological systems in the Mississippi River Basin along with studies of local Iowa agricultural watersheds. Contributors from multiple academic and professional disciplines discuss how agricultural policies have contributed to current environmental conditions, and, in what the authors term 'alternative futures' for agricultural landscapes, envision how new policy can help achieve more beneficial patterns.

Book Description
Although the 12 species representing three waterfowl tribes described in this volume are not closely related, they fortuitously provide an instructive example of adaptive evolutionary radiation within the much larger waterfowl lineage (the family Anatidae), especially as to their divergent morphologies, life histories, and social behaviors. The whistling-ducks (Dendrocygna), with three known North American species, are notable for their permanent pair-bonds, extended biparental family care, and strong social cohesion. In contrast, males of the five typical pochards of North American diving ducks (Aythya) establish monogamous pair-bonds that are maintained only long enough to assure that the female's eggs are fertilized. The endpoint of this behavioral gradient, promiscuity or polygyny, exists among at least some of the typical stifftails (Oxyura). Such diverse reproductive strategies have exerted powerful evolutionary influences on interspecies variations in sexual dimorphism, sexual behavior, anatomy, ecology, and other traits. This volume includes more than 63,000 words, plus some 200 maps, photos, drawings, and sketches, and nearly 650 literature citations. It is the last of five volumes that describe all 55 waterfowl species that have been historically documented in North America; collectively, the volumes total over 300,000 words, with nearly 3,000 literature citations, and more than 600 maps, photos, drawings, and sketches.
