Winging directly in on the birdlovers is this collection of pieces from a number of well-known pens. Represented, often by more than one piece, are John Burroughs, John James Audubon, John Muir, E.B. White, Roger Tory Peterson, Edwin Way Teale, Rachel Carson, Sally Carrighar, and many others. The subjects range the air from the tip to stem of the Continent, and vary from pleasant descriptions of bird-watching to lessons on habitat and even the Department of the Interior's article on the how and why of bird-banding. The relation of birds to each other, the exploration of their capacities and limits and lives, the problems of extinction and conservation, what they mean to man and what man means to them in the interlocking of lives are part of the story. Water ouzels, house wrens, Canadian geese, passenger pigeons, cardinals, eagles are present here, and the comments range from the most recent difficulties in claiming territory over which a bulldozer now reigns back to Gonzalo de Oviedo's ""summarie"" of the Indies' birdlife following Columbus in 1525. A generous volume with a built-in market.
