The decline of bird species in a wide range of North American habitats -- forests, prairies, shrublands, mountain regions, marshes, and deserts -- has inspired two decades of intense scientific study of bird ecology and conservation. But for professional scientists and amateur birders alike, interpreting the results of these diverse studies is often complex and bewildering. This accessible book pulls together recent research on bird species and habitats to show how basic ecological principles apply in seemingly different situations. Robert A. Askins provides an engaging introduction to bird ecology and concepts of landscape ecology, focusing on such intriguing species as Bachman's Warbler, Red Crossbill, Mountain Plover, and Marbled Murrelet.Understanding the ancient landscapes of North America and how humans have changed them, Askins says, is essential for devising plans to protect and restore bird populations. In addition to such obvious changes to the landscape as the clearing of forests and plowing of prairies, more subtle changes also dramatically affect birds. Species may disappear when we interrupt natural disturbances by suppressing wildfires or trapping out beaver, or when we disrupt habitat with roads and housing developments. Askins challenges some of the assumptions that underlie current conservation efforts and offers concrete recommendations, based on sound ecological principles, for protecting the rich natural diversity of North America's birds.

Scores of bird species are in decline throughout North America. But the extent of that decline, writes zoologist Robert Askins, is unknown. Newspapers, for instance, report one day that songbird species are widely threatened, another day that songbirds seem to be thriving, offering conflicting views that, Askins hints, seem not to take into account the phenomena of migration and the very real destruction of the natural world.
Drawing on the methods of landscape ecology, Askins looks at ways in which to measure the health of individual habitats. He pays special attention to seemingly habitat-threatening events such as fire and flood, which generations of conservation managers and foresters have attempted to suppress, but that are important mechanisms in maintaining the balance of nature. He also revisits principles that are becoming better understood--among them the fact that some species, such as the controversial spotted owl and the less-publicized upland sandpiper, require large areas of undisturbed habitat in order to survive. Those large areas are a commodity that development is making ever more rare, and, Askins points out, most declining bird species are associated with what he calls "lost landscapes," once-plentiful habitats that have been erased or transformed. Only through a vigorous program of habitat restoration and conservation can North America's birds--and other wildlife species--be protected from further ruin. Askins's book is an eye-opening and instructive work of scientific inquiry. --Gregory McNameeAbout the Author:
