Birds in Jeopardy : The Imperiled and Extinct Birds of the United States and Canada: Including Hawaii and Puerto Rico. This book is the first concise, authoritative review of the status of the birds currently imperiled in the United States and Canada - those that are federally listed as Endangered or Threatened and those that are listed by the National Audubon Society as suffering local or regional or widespread decline. It also treats the birds that have been driven to extinction in the past two centuries, since the stories of their somber fates can help us learn how to save the other birds that are in jeopardy.
