Twenty-five years after its first publication, this classic Let's-Read-and-Find-Out Science book has been reissued with a few minor changes in the simple text and with entirely new full-color illustrations. Watson has replaced her original crosshatched ink drawings with big, bright, clear collage-type pictures that show how animals and people sleep and what happens when they don't get their rest.

Gr 2-4--A straightforward account of the first brood of peregrine falcon chicks to hatch in the wild in the eastern U.S. in 30 years--on a ledge of a Baltimore skyscraper. General facts about falcon behavior and habitat; explanations of how the peregrine population was affected by DDT; and scientists' efforts to save the species provide the background for the story of one bird. Scarlett had been raised at a special research facility, banded, and released into the wild. She landed on a skyscraper, waited five years for a mate, and raised her brood of four. Lloyd's excellent watercolor illustrations capture the variety of falcon positions from nesting to flight, and the artist's perspective of the cityscape as viewed from Scarlett's eyrie 33 stories above enhance the text. Additional information about five species of falcons and a list of places to observe them round out the presentation. A good introduction to birds of prey and how wildlife is dependent on the environment.--Diane Nunn, Richard E. Byrd Elementary School, Glen Rock, NJ
