Book Description
"Why are male birds often so brightly colored? Why do some birds lay more eggs than others? Will bird species adapt to climate change? In How Birds Evolve, Douglas Futuyma invites readers into the amazing world of bird evolution to answer these and other questions. Futuyma's goal in this book is not to offer a comprehensive evolutionary history of birds, but to explore how the processes of evolution produced the distinctive features and behaviors we observe in birds today as well as their impressive diversity. Using one or two birds per chapters as a lens into broader questions, Futuyma explores how a bird's evolutionary history helps us understand the diversity of species and the bird tree of life and how natural selection explains most of the characteristics of birds from how populations adapt to sexual selection and birds' amazing social behavior. Futuyma concludes by discussing the future of birds, particularly patterns of extinction and whether they can adapt to a changing climate. Ultimately, Futuyman wants readers to see that evolutionary biology helps us to better understand birds, and that the reverse is also true: studies of birds have informed almost every aspect of evolutionary biology, from Darwin to today"--

Book Description
The New York Times–bestselling author of H is for Hawk explores the human relationship to the natural world in this “dazzling” essay collection (Wall Street Journal). In Vesper Flights, Helen Macdonald brings together a collection of her best loved essays, along with new pieces on topics ranging from nostalgia for a vanishing countryside to the tribulations of farming ostriches to her own private vespers while trying to fall asleep. Meditating on notions of captivity and freedom, immigration and flight, Helen invites us into her most intimate experiences: observing the massive migration of songbirds from the top of the Empire State Building, watching tens of thousands of cranes in Hungary, seeking the last golden orioles in Suffolk’s poplar forests. She writes with heart-tugging clarity about wild boar, swifts, mushroom hunting, migraines, the strangeness of birds’ nests, and the unexpected guidance and comfort we find when watching wildlife.

Book Description
Everyday kids learn how they can help protect bird species, near and far, with the award-winning book Counting Birds—the real-life story behind the first annual bird count. What can you do to help endangered animals and make a positive change in our environment? Get counting! Counting Birds is a beautifully illustrated book that introduces kids to the idea of bird counts and bird watches. Along the way, they will learn about Frank Chapman, an ornithologist who wanted to see the end of the traditional Christmas bird hunt, an event in which people would shoot as many birds as possible on Christmas. Chapman, using his magazine Bird-Lore to promote the idea of counting birds, founded the first annual bird count. More than a century after the first bird count, bird counting helps professional researchers collect data, share expertise, and spread valuable information to help all kinds of birds around the world, from condors to hawks to kestrels and more. Counting Birds introduces kids to a whole feathered world that will fascinate and inspire them to get involved in conservation and become citizen scientists. 2019 Outstanding Science Trade Book for Students: K–12 (National Science Teachers Association and Children's Book Council) 2019 Best STEM Book for K–12 Students (National Science Teachers Association and the Children's Book Council) Winner of the 2019 Riverby Award (The John Burroughs Association) Recipient of the 2019 Green Earth Book Award Honor (The Nature Generation)

Book Description
Speciation is the process by which co-existing daughter species evolve from one ancestral species - e.g., humans, chimpanzees, and gorillas arising from a common ancestor around 5,000,000 years ago. However, many questions about speciation remain controversial. The Birds of Northern Melanesia provides by far the most comprehensive study yet available of a rich fauna, composed of the 195 breeding land and fresh-water bird species of the Bismarck and Solomon Archipelagoes east of New Guinea. This avifauna offers decisive advantages for understanding speciation, and includes famous examples of geographic variation discussed in textbooks of evolutionary biology. The book results from 30 years of collaboration between the evolutionary biologist Ernst Mayr and the ecologist Jared Diamond. It shows how Northern Melanesian bird distributions provide snapshots of all stages in speciation, from the earliest (widely distributed species without geographic variation) to the last (closely related, reproductively isolated species occurring sympatrically and segregating ecologically). The presentation emphasizes the wide diversity of speciation outcomes, steering a middle course between one-model-fits-all simplification and ungeneralizable species accounts. Questions illuminated include why some species are much more prone to speciate than others, why some water barriers are much more effective at promoting speciation than others, and whether hypothesized taxon cycles, faunal dominance, and legacies of Pleistocene land bridges are real. These years of study have resulted in a huge database, complete with distributions of all 195 species on 76 islands, together with their taxonomy, colonization routes, ecological attributes, abundance, and overwater dispersal. Color plates depict 88 species and allospecies, many of which have never been seen before. For students of speciation, Northern Melanesian birds now constitute a model system against which other biotas can be compared. For population biologists interested in other problems besides speciation, this rich database can now be mined for insights.
