A wing and a prayer : the race to save our vanishing birds
\"In the fall of 2019, headlines delivered shocking news: nearly three billion birds in North America have vanished over the past fifty years. No species has been spared, from the most delicate jeweled hummingbirds to scrappy black crows, from a rainbow of warblers to common birds such as owls and sparrows. For the past year, veteran journalists Anders and Beverly Gyllenhaal traveled more than 25,000 miles across the Americas, chronicling costly experiments, contentious politics, and new technologies to save our beloved birds from the brink of extinction. Through this compelling drama, A Wing and a Prayer offers hope and an urgent call to action: Birds are dying at an unprecedented pace. But there are encouraging breakthroughs across the hemisphere and still time to change course, if we act quickly\"-- Provided by publisher

Shorebird ecology, conservation, and management
Shorebirds are model organisms for illustrating the principles of ecology and excellent subjects for research. Their mating systems are as diverse as any avian group, their migrations push the limits of endurance, and their foraging is easily studied in the open habitats of estuaries and freshwater wetlands. This comprehensive text explores the ecology, conservation, and management of these fascinating birds. Beginning chapters examine phylogenetic relationships between shorebirds and other birds, and cover shorebird morphology, anatomy, and physiology. A section on breeding biology looks in detail at their reproductive biology. Because shorebirds spend much of their time away from breeding areas, a substantial section on non-breeding biology covers migration, foraging ecology, and social behavior. The text also covers shorebird demography, population size, and management issues related to habitat, predators, and human disturbances. Throughout, it emphasizes applying scientific knowledge to the conservation of shorebird populations, many of which are unfortunately in decline.

Neither Scale of Response Nor Threshold in Habitat Availability Is Conserved Across Species of Forest-Dwelling Songbirds Responding to Habitat Loss
Thresholds can be an effective tool in conservation planning, as they can form a defensible target for habitat conservation or restoration. Generalized thresholds must be used with caution, however, as threshold responses may vary with species and spatial scale. The objectives of this study were to identify the scales at which forest-dwelling birds respond to both habitat availability and critical thresholds in forest cover associated with their occurrence, and to assess if life history traits relate to either scale of response or critical threshold. Using point count data from the Ontario Breeding Bird Atlas, I generated concentric buffers ranging from 100 m to 10 km radius around a random subset of point counts and described forest cover and species occurrence within each buffer. I assessed the likelihood of occurrence of each species at each scale of analysis using logistic regression and identified forest cover thresholds below which the occurrence of each species becomes unlikely using fitted regression curves and ROC plots. Species varied in their response to both landscape scale and forest cover, based on relative growth rate, clutch size, and site fidelity. The mean response to forest cover was 30.8%, with landscape scale ranging from 200 m to 9 km. Despite this range, pragmatic approaches to conservation planning are still possible.

Spatial and thematic bias in the scientific literature on farmland birds across the globe
The global biodiversity crisis and constantly growing human impact on the natural environment call for more evidence where conservation actions are the most urgent. As the agricultural lands are under increased pressure of growing human food needs here the literature survey on farmland bird conservation (FBC) was conducted to reveal geographical distribution in research intensity, the topics addressed and to identify potential drivers for the worldwide scientific effort. The Scopus database search has revealed 2290 papers dedicated to FBC from the period 1990–2020. The distribution was spatially uneven with most papers published in Western Europe and North America. Scientific collaboration was also spatially biased in favor of countries located close to each other and having high scientific capacity. The analysis also revealed 139 terms representing main topics raised in FBC research. The number of FBC papers per country was positively correlated with Gross Domestic Production (GDP), the total number of scientific papers, and number of threatened species, and negatively with the GDP from agricultural production, whereas it was not related to area of agricultural lands or bird species richness. Spatial and thematic biases in studies of farmland birds may have important consequences since uneven scientific evidence constrains development of proper conservation solutions and limits their implementation. We conclude that research on FBC should be globally coordinated and flexible enough to undertake burning conservation problems adjusted to regional differences in agriculture, socio-economy, and bird diversity.

Winged Sentinels
'The ability of the birds to show us the consequences of our own actions is among their most important and least appreciated attributes. Despite the free advice of the birds, we do not pay attention', said Marjory Stoneman Douglas in 1947. From ice-dependent penguins of Antarctica to songbirds that migrate across the Sahara, birds' responses provide early warning signs of the impact of climate change. Winged Sentinels: Birds and Climate Change uses colourful examples to show how particular groups of birds face heightened threats from climate change and to explore how we can help birds adapt in a warming world. Generously illustrated with colour photographs, the book is a fascinating insight into what climate change means for birds, and the potential consequences of ignoring these warning signs.

fall and rise of the wetlands of California's Great Central Valley
This is the first comprehensive environmental history of California’s Great Central Valley, where extensive freshwater and tidal wetlands once provided critical habitat for tens of millions of migratory waterfowl. Weaving together ecology, grassroots politics, and public policy, Philip Garone tells how California’s wetlands were nearly obliterated by vast irrigation and reclamation projects, but have been brought back from the brink of total destruction by the organized efforts of duck hunters, whistle-blowing scientists, and a broad coalition of conservationists. Garone examines the many demands that have been made on the Valley’s natural resources, especially by large-scale agriculture, and traces the unforeseen ecological consequences of our unrestrained manipulation of nature. He also investigates changing public and scientific attitudes that are now ushering in an era of unprecedented protection for wildlife and wetlands in California and the nation.

Urban bird ecology and conservation
Now that more than half of the world's population lives in cities, the study of birds in urban ecosystems has emerged at the forefront of ornithological research. An international team of leading researchers in urban bird ecology and conservation from across Europe and North America presents the state of this diverse field, addressing classic questions while proposing new directions for further study. Areas of particular focus include the processes underlying patterns of species shifts along urban-rural gradients, the demography of urban birds and the role of citizen science, and human-avian interaction in urban areas. This important reference fills a crucial need for scientists, planners, and managers of urban spaces and all those interested in the study and conservation of birds in the world's expanding metropolises.
