Book Description
The Painted Bunting’s Last Molt explores fatherhood, parenting, and separation anxiety; and the ways in which time and memory are both a prison and a giver of joy. Fifteen years in the making, Virgil Suárez’s new collection uses his mother’s return to Cuba after 50 years of exile as a catalyst to muse on familial relationships, death, and the passing of time. Moon Decima If it were the Eucharist, it’d be hard to swallow, this moon of lost impressions, a boy in deep water, something tickling his skin. This memory of weight- lessness—a kite that somehow still manages to hover in the dog mouth blackness of sky. This is a cut out moon of lost children, or is it a savior’s moon? This boy will float on home, or be swallowed by the water. Above the pines and mangroves, this moon hangs unrelenting. Is it the one eye of an indifferent God that remains open just so?

Book Description
Birders who come to the American Southwest often keep an eye out for Mexican species that stray across the border. Many neotropical migrants of western North America winter in Sonora, and a host of hummingbirds make their home south of the border as well. This eagerly awaited volume by two respected authorities covers more than 500 species of birds and contains a vast amount of information not available elsewhere. The Birds of Sonora describes all the species known from that state and includes information on distribution, seasonal patterns of occurrence, abundance, and habitats. The first book of its kind in more than half a century to treat birds of this Mexican state immediately south of Arizona, it also contains details of nesting activity for breeding species, provides insight into factors influencing distribution, and notes historical changes in status. Each account is accompanied by a range map depicting the bird's range in Sonora—valuable information not available from any other source and useful to anyone interested in the distribution and ecology of North American birds. Drawings by internationally known wildlife artist Ray Harm enhance many of the entries. Because other books on Mexican birds don't treat Sonora in detail, The Birds of Sonora is an indispensable resource for birders, and its background descriptions of Sonoran geography, climate, and habitats also make it a key reference for conservation and land use planning. A useful companion to field guides, it is a narrative account that puts readers in touch with birds of this important biogeographic area.

Book Description
The first comprehensive review of all aspects of the biology of moult, drawing information from across the literature and in all birds, from penguins to passerines. Feathers are amazing structures unique to birds and, for a variety of reasons, they need to be renewed periodically as a whole in a process called moult. During this process, all of the functions of plumage are impaired and most aspects of a bird's life are affected. Every moult determines a bird's appearance anew, and restores plumage efficacy for flight and insulation. Moult profoundly affects physiology and the organization of the annual cycle, and it constrains reproduction and migration. Given these major impacts, which are equal to the other annual challenges of reproduction and migration, it is surprising that research on moult has largely been so neglected a subject. Lukas Jenni and Raffael Winkler have brought together the widely scattered results of studies on the processes and consequences of moult in birds. This book opens with an overview of the functions of plumage, and of feather maintenance and feather wear, and then introduces the two functions of moult: replacement of worn feathers and adjustment of plumage characteristics and appearance. The body of the book then examines feather-growth and the physiology, energetics and control of moult, and how various other physiological processes interact with moult and may compensate for its costs. Significantly, the authors explain how variations in moult and feather quality affect a bird's overall plumage quality, and they highlight the resulting consequences in terms of physical performance, appearance and signalling. Finally, there is a review of all the various solutions that birds have developed to fit moult into the annual cycle. This long-awaited book covers for the first time all aspects of the biology of moult and fills an important gap in the literature, completing our understanding of how the most important annual events in a bird's life fit together into a coherent whole. It draws on a wide range of information – from penguins to small passerines, from raptors to wildfowl – to highlight the variety of the subject and to pinpoint the many gaps in our knowledge along with avenues for fruitful further research.

Book Description
For centuries biologists have tried to understand the underpinnings of avian migration: where birds go and why, why some migrate and some do not, how they adapt to a changing environment, and how migratory systems evolve. Twenty-five years ago the answers to many of these questions were addressed by a collection of migration experts in Keast and Morton's classic work Migrant Birds in the Neotropics. In 1992, Hagan and Johnston published a follow-up book, Ecology and Conservation of Neotropical Migrant Landbirds. In Birds of Two Worlds Russell Greenberg and Peter Marra bring together the world's experts on avian migration to discuss its ecology and evolution. The contributors move the discussion of migration to a global stage, looking at all avian migration systems and delving deeper into the evolutionary foundations of migratory behavior. Readers interested in the biology, behavior, ecology, and evolution of birds have waited a decade to see a worthy successor to the earlier classics. Birds of Two Worlds will complete the trilogy and become indispensable for ornithologists, evolutionary biologists, serious birders, and public and academic libraries.
