Gr 3-5-In his signature photo-essay format with appealing full-page color photographs, Simon provides a broad overview of Antarctic penguins' physical characteristics and behavior. Mating, egg laying, and care of the young are described, as are the animal predators and human factors that threaten the survival of penguins. A few species-emperor, king, gentoo, macaroni, Adelie-each get an individual page of description. Readers will find more detailed information in Laurence Pringle's Penguins! Strange and Wonderful (Boyds Mills, 2007) and in several of the many other books available on this popular animal, but Simon's photographs are eye-catching. A serviceable introduction that will have familiarity for the author's many fans.-Margaret Bush, Simmons College, Boston Copyright 2007 Reed Business Information.
