How Do Birds Find Their Way? (Let's-Read-and-Find-Out Science 2)
Grade 1-3?Gans limits her discussion to basic facts about birds and their instinctive travel habits. She tells what ornithologists know about migration patterns and presents some of their theories about how birds know when to fly and their different means of navigation. Watercolor and colored-pencil illustrations show several species and their habitats, as well as a few maps and charts. The careful coloring and identification of specific birds add to the value of this attractive introductory text, but its lack of an index limits its use for reports.?Kathy East, Wood County District Public Library, OHCopyright 1996 Reed Business Information, Inc.
