For over three decades, contemporary Native American artist Hock E Aye Vi Edgar Heap of Birds has pursued a disciplined practice in multiple media, having shown his paintings, drawings, prints, and text-based conceptual art throughout numerous national and international galleries and public spaces. In the first book-length study of this important artist, Bill Anthes analyzes Heap of Birds's art and politics in relation to the international contemporary art scene, Native American history, and settler colonialism. Foregrounding how Heap of Birds roots his practice in Cheyenne spirituality and an indigenous way of seeing and being in the world, Anthes describes how Heap of Birds likens his art to "sharp rocks"—weapons delivering trenchant critiques of the loss of land, life, and autonomy endured by Native Americans. Whether appearing as interventions in public spaces or in a gallery, Heap of Birds's carefully honed artworks pose questions about time, modernity, identity, power, and the meaning and value of contemporary art in a global culture. 

 

Named after a Sardinian princess of the fourteenth century who established laws protecting falcons, Eleonora's falcon is the only European bird to breed in autumn and feed its brood on the mass of birds that migrate from Europe to Africa between July and October. It breeds on small Mediterranean islands in colonies of up to 200 pairs and hunts often in groups, preying on more than 90 species of migrant birds. During the winter this falcon visits the rain-soaked woodlands of Madagascar.

In this study—illustrated beautifully and extensively with 59 line drawings and 38 photographs—Hartmut Walter shows how the unique geographical and biological situation of Falco eleonorae makes the species' health an important indicator of environmental decay. For though it lives in relatively isolated areas, Eleonora's falcon nevertheless may ingest the many pollutants contained in its diet of birds migrating from industrial Europe. Walter, who has studied raptors on several continents and has been an ornithologist since his early youth, examines several discrete colonies of Eleonora's falcon. He concentrates on the species' intraspecific behavior and ecology—such as the falcons' aggressive actions, hunting strategies, and response to fluctuating environmental conditions—and investigates their evolutionary past.

Sprinkled across the tropical Pacific, the innumerable islands of Oceania are home to some of the most unique bird communities on the planet, and they sustain species found nowhere else on earth. Many of the birds that live in this region are endangered, however; many more have become extinct as a result of human activity, in both recent and prehistoric times.

Reconstructing the avian world in the same way archeologists re-create ancient human societies, David Steadman—a leading authority on tropical Pacific avian paleontology—has spent the past two decades in the field, digging through layers of soil in search of the bones that serve as clues to the ancient past of island bird communities. His years of indefatigable research and analysis are the foundation for Extinction and Biogeography of Tropical Pacific Birds, a monumental study of the landbirds of tropical Pacific islands—especially those from Fiji eastward to Easter Island—and an intricate history of the patterns and processes of island biology over time. 

Using information gleaned from prehistoric specimens, Steadman reconstructs the birdlife of tropical Pacific islands as it existed before the arrival of humans and in so doing corrects the assumption that small, remote islands were unable to support rich assemblages of plants and animals. Easter Island, for example, though devoid of wildlife today, was the world’s richest seabird habitat before Polynesians arrived more than a millennium ago. The forests of less isolated islands in the Pacific likewise teemed with megapodes, rails, pigeons, parrots, kingfishers, and songbirds at first human contact. 

By synthesizing data from the distant past, Steadman hopes to inform present conservation programs. Grounded in geology, paleontology, and archeology, but biological at its core, Extinction and Biogeography of Tropical Pacific Birds is an exceptional work of unparalleled scholarship that will stimulate creative discussions of terrestrial life on oceanic islands for years to come.

Along with reproduction, balancing energy expenditure with the limits of resource acquisition is essential for both a species and a population to survive. But energy is a limited resource, as we know well, so birds and mammals—the most energy-intensive fauna on the planet—must reduce energy expenditures to maintain this balance, some taking small steps, and others extreme measures.

Here Brian K. McNab draws on his over sixty years in the field to provide a comprehensive account of the energetics of birds and mammals, one fully integrated with their natural history. McNab begins with an overview of thermal rates—much of our own energy is spent maintaining our 98.6?F temperature—and explains how the basal rate of metabolism drives energy use, especially in extreme environments. He then explores those variables that interact with the basal rate of metabolism, like body size and scale and environments, highlighting their influence on behavior, distribution, and even reproductive output. Successive chapters take up energy and population dynamics and evolution. A critical central theme that runs through the book is how the energetic needs of birds and mammals come up against rapid environmental change and how this is hastening the pace of extinction.
