Book
Urban Ornithology
Urban Ornithologyis the first quantitative historical analysis of any New York City natural area's birdlife and spans the century and a half from 1872 to 2016. Only Manhattan's Central and Brooklyn's Prospect Parks have preliminary species lists, not revised since 1967, and the last book examining the birdlife of the entire New York City area is now more than fifty years old.
This book updates the avifaunas of those two parks, the Bronx, and other New York City boroughs. It treats the 301 bird species known to have occurred within its study area-Van Cortlandt Park and the adjacent Northwest Bronx-plus 70 potential additions. Its 123 breeding species are tracked from 1872 and supplemented by quantitative breeding bird censuses from 1937 to 2015. Gains and losses of breeding species are discussed in light of an expanding New York City inexorably extinguishing unique habitats.

In the Field, Among the Feathered
America is a nation of ardent, knowledgeable birdwatchers. But how did it become so? And what role did the field guide play in our passion for spotting, watching, and describing birds? This book tells the history of field guides to birds in America from the Victorian era to the present, relating changes in the guides to shifts in science, the craft of field identification, and new technologies for the mass reproduction of images. Drawing on experience and a wealth of archival research, this book shows how the twin pursuits of recreation and conservation have inspired birders and how field guides have served as the preferred method of informal education about nature for well over a century. The book begins with the first generation of late nineteenth-century birdwatchers who built the hobby when opera glasses were often the best available optics and bird identification was sketchy at best. As America became increasingly urban, birding became more attractive, and with Roger Tory Peterson's first field guide in 1934, birding grew in both popularity and accuracy. By the 1960s recreational birders were attaining new levels of expertise, even as the environmental movement made birding's other pole, conservation, a matter of human health and planetary survival. The book concludes by showing how recreation and conservation have reached a new balance in the last forty years, as scientists have increasingly turned to amateurs, whose expertise had been honed by the new guides, to gather the data they need to support habitat preservation.

American Bird Conservancy guide to bird conservation
Whether we live in cities, in the suburbs, or in the country, birds are ubiquitous features of daily life, so much so that we often take them for granted. But even the casual observer is aware that birds don’t fill our skies in the number they once did. That awareness has spawned conservation action that has led to notable successes, including the recovery of some of the nation’s most emblematic species, such as the Bald Eagle, Brown Pelican, Whooping Crane, and Peregrine Falcon. Despite this, a third of all American bird species are in trouble—in many cases, they’re in imminent danger of extinction. The most authoritative account ever published of the threats these species face, The American Bird Conservancy Guide to Bird Conservation will be the definitive book on the subject. The Guide presents for the first time anywhere a classification system and threat analysis for bird habitats in the United States, the most thorough and scientifically credible assessment of threats to birds published to date, as well as a new list of birds of conservation concern. Filled with beautiful color illustrations and original range maps, the Guide is a timely, important, and inspiring reference for birders and anyone else interested in conserving North America’s avian fauna. But this book is far more than another shout of crisis. The Guide also lays out a concrete and achievable plan of long-term action to safeguard our country’s rich bird life. Ultimately, it is an argument for hope. Whether you spend your early weekend mornings crouched in silence with binoculars in hand, hoping to check another species off your list, or you’ve never given much thought to bird conservation, you’ll appreciate the visual power and intellectual scope of these pages.

Welcome to subirdia : sharing our neighborhoods with wrens, robins, woodpeckers, and other wildlife
\"Welcome to Subirdia presents a surprising discovery: the suburbs of many large cities support incredible biological diversity. Populations and communities of a great variety of birds, as well as other creatures, are adapting to the conditions of our increasingly developed world. In this fascinating and optimistic book, John Marzluff reveals how our own actions affect the birds and animals that live in our cities and towns, and he provides ten specific strategies everyone can use to make human environments friendlier for our natural neighbors. Over many years of research and fieldwork, Marzluff and student assistants have closely followed the lives of thousands of tagged birds seeking food, mates, and shelter in cities and surrounding areas. From tiny Pacific wrens to grand pileated woodpeckers, diverse species now compatibly share human surroundings. By practicing careful stewardship with the biological riches in our cities and towns, Marzluff explains, we can foster a new relationship between humans and other living creatures--one that honors and enhances our mutual destiny.\" -- Publisher's description.

The invasive Red-vented bulbul
Invasive alien species are a major cause of biodiversity loss globally, but especially on islands where high species richness and levels of endemism accentuate their impacts. The Red vented bulbul (Pycnonotus cafer), a tropical passerine bird that has been introduced widely across locations of high conservation value, is considered an extreme pest. It is currently expanding its range in New Caledonia, one of the world's biodiversity hotspots. Decisive recommendations on management strategies are required urgently to inform local managers and policy makers, but they should be based on quantitative local evidence, not just on expert opinion. The Red-vented bulbul is widely blamed for its impacts on biodiversity, especially through competition. We used data from 2,472 point counts to explore the abundance relationships between the Red-vented bulbul and 14 other species of bird. Our results revealed a negative relationship between the occurrence of the bulbul and the mean abundance of nine species, all native (or endemic, n = 3) to the New Caledonia archipelago. In contrast, the abundance of other introduced species such as Acridotheres tristis (Common myna), Passer domesticus (House sparrow) and Spilopelia chinensis (Spotted dove) were not affected by the Red-vented bulbul. Moreover, temporal trends in the abundance of impacted species suggest that the Red-vented bulbul may cause niche contractions rather than mortality for native species in man-modified habitats. Monitoring and control of the Red-vented bulbul is recommended to prevent on-going impacts on native bird communities throughout New Caledonia, and its impact on native bird communities elsewhere should be quantified.
