Available in PDF, EPUB and Kindle. Book excerpt: At a time when the world is seeing its species rapidly go extinct, the Kirtland's warbler is not just a survivor, it's a rock star. The Kirtland's warbler is the rarest warbler species in North America and will always be rare because of its persnickety nesting preferences. But when the total population fell below 400 birds in the 1970s and 1980s---driven largely by a loss of habitat and the introduction of a parasite---a small group of dedicated biologists, researchers, and volunteers vowed to save the Kirtland's warbler despite long odds. This is the story of the warbler's survival and gradual recovery, the people and policies that kept it from extinction, and the ongoing challenges that may again jeopardize the bird's future. In The Kirtland's Warbler, William Rapai explores the bird's fascinating natural history as well as the complex and evolving relationships between the warbler, its environment, its human protectors, and state and federal policies that today threaten to eradicate decades of work done on the species' behalf. Beginning with an account of the warbler's discovery in the mid-nineteenth century and ornithologists' desperate hunt for information on the elusive new species, the book goes on to examine the dramatic events that quickly led to the warbler's precarious status and its eventual emergence as a lightning rod for controversy. The Kirtland's warbler is often described as a "bird of fire" for its preference for nesting in areas cleared by wildfire. But it also warrants the name for the passion it ignites in humans. Both tragic and uplifting, the story of this intriguing bird is a stirring example of how strong leadership, vision, commitment, sustained effort, and cooperation can come together to protect our natural world.

This book was released on 2014-09-05 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past two centuries, cowbirds have increased in numbers and extended their range across North America, while many of the native songbird species whose nests they parasitize to raise their young have declined. This timely book collects forty essays by most of the principal authorities on the biology and management of cowbirds. The book's goals are to explore the biology of cowbirds, the threats they pose to host species and populations, and the management programs that are being undertaken to minimize these threats. The book is organized into five sections, each with an extended editors' introduction that places the contributions in a broad, up-to-date setting. The sections cover: The changing abundance of cowbirds and the ways in which their numbers can be estimated. Host choice by cowbirds, the negative effects of cowbirds on particular host species, and the daily patterns of cowbird behavior. Behavioral interactions between cowbirds and specific host species. Patterns of cowbird abundance and host use across varying landscapes. Management programs designed to control cowbirds and protect threatened songbirds.

This book was released on 1997 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This study examines prey availability as a factor influencing breeding habitat selection by Kirtland's Warblers (Dendroica kirtlandii), and characterizes the foraging behavior of this endangered species. Kirtland's Warblers nest on the ground in early-successional jack pine forests in northern Lower Michigan. The species may reject old jack pine stands for nesting due to decreased prey density in lower branches and ground vegetation of old stands. Insects were captured in young and old nesting habitat and in mature jack pine too old to be attractive for breeding, and birds were observed foraging in young and old nesting habitat. Insect biomass in low vegetation was less in old nesting habitat than in young nesting habitat, and was much less in mature habitat. Kirtland's Warblers in old nesting habitat did not forage higher than those in young nesting habitat, suggesting that the decrease in insect biomass in old nesting habitat is not great enough to affect the birds. Managed plantations and natural wildfire-regenerated jack pine stands were very similar in terms of insect abundance, diversity, and distribution, and warbler behavior. Warblers foraged most often on jack pines, but also used ground vegetation and pin oak trees as foraging substrates. The proportion of foraging attempts in oak varied widely among stands, suggesting that warblers use oak in proportion to its availability. Female Kirtland's Warblers foraged significantly lower than males, following a general trend for species of parulid warblers.
Download or read book The Kirtland s Warbler written by William Rapai and published by University of Michigan Press. This book was released on 2012-02-08 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book looks at the Kirtland’s warbler and wildlife conservation in a way that no other book has. It looks back on the history of this unique bird, examines the people and policies that kept the warbler from extinction, explores the cult of personality that surrounds it, and examines the challenges of the future—all through the eyes of the people who have acted so passionately on its behalf. The story of the Kirtland’s warbler is a story of complex relationships between the bird and its environment, the humans who interact with it, and the complex government policies that affect it. And now, just when it appears that the Kirtland’s warbler has recovered for good, a change in its status may send the warbler’s population into a downward spiral once again.

Oliarnyk and published by Kemptville : Eastern Ontario Model Forest = Forét modèle de l'est de l'Ontario. This book was released on 1996 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the breeding biology, reproductive success and habitat use of a population of Cerulean Warblers (Dendroica cerulea), a poorly understood, threatened migrant songbird. I established study sites in three areas of mature deciduous forest in the Frontenac Axis region of Ontario: two in unmanaged forest, and the third in an area of selective cutting. Reproductive success was high over the two years of the study, with 20 of 27 pairs (74%) successfully fledging at least one young. Nest failure due to predation was relatively low (14.8%), and there were no known instances of brood parasitism by Brown-headed Cowbirds (Molothrus ater). High rates of success, associated with low rates of predation and brood parasitism, are likely attributable to the large area of contiguous forest in this region, which buffers the pressures of forest "edge effects."

Download or read book Conservation Biology written by Fred Van Dyke and published by Springer Nature. This book was released on 2020-07-07 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a thorough, up-to-date examination of conservation biology and the many supporting disciplines that comprise conservation science. In this, the Third Edition of the highly successful Conservation Biology: Foundations, Concepts, Applications, the authors address their interdisciplinary topic as it must now be practiced and perceived in the modern world. Beginning with a concise review of the history of conservation, the authors go on to explore the interplay of conservation with genetics, demography, habitat and landscape, aquatic environments, and ecosystem management, and the relationship of all these disciplines to ethics, economics, law, and policy. An entirely new chapter, The Anthropocene: Conservation in a Human-Dominated Nature, breaks new ground in its exploration of how conservation can be practiced in anthropogenic biomes, novel ecosystems, and urban habitats. The Third Edition includes the popular Points of Engagement discussion questions used in earlier editions, and adds a new feature: Information Boxes, which briefly recap specific case histories described in the text. A concluding chapter offers insight into how to become a conservation professional, in both traditional and non-traditional roles. The authors, Fred Van Dyke and Rachel Lamb, draw on their expertise as field biologists, wildlife managers, consultants to government and industry, and scholars of environmental law, policy, and advocacy, as well as their many years of effective teaching experience. Informed by practical knowledge and acquired skills, the authors have created a work of exceptional clarity and readability which encompasses both systemic foundations as well as contemporary developments in the field. Conservation Biology: Foundations, Concepts, Applications will be of invaluable benefit to undergraduate and graduate students, as well as to working conservation scientists and managers. This is an amazing resource for students, faculty, and practitioners both new and experienced to the field. Diane Debinski, PhD Unexcelled wisdom for living at home on Wonderland Earth, the planet with promise, destined for abundant life. Holmes Rolston, PhD Van Dyke and Lamb have maintained the original text’s emphasis on connecting classical ecological and environmental work with updated modern applications and lucid examples. But more importantly, the third edition contains much new material on the human side of conservation, including expanded treatments of policy, economics, and climate change. Tim Van Deelen, PhD Fred Van Dyke and Rachel Lamb break new ground in both the breadth and depth of their review and analysis of this crucially important and rapidly changing field. Any student or other reader wishing to have a comprehensive overview and understanding of the complexities of conservation biology need look no further – this book is your starting point! Simon N.
