简介：
Many birds travel thousands of miles each year, migrating between summer and winter homes. Just how they find their way back and forth, sometimes returning to the exact same nesting grounds each year, has puzzled ornithologists for years. Roma Gans details the many theories scientists have proposed to explain the mysteries of migration.
【媒体评论】
Gans limits her discussion to basic facts about birds andtheir instinctive travel habits. She tells what ornithologists knowabout migration patterns and presents some of their theories abouthow birds know when to fly and their different means of navigation.Watercolor and colored-pencil illustrations show several speciesand their habitats, as well as a few maps and charts. The carefulcoloring and identification of specific birds add to the value ofthis attractive introductory text, but its lack of an index limitsits use for reports.
Ages 4-8. Pictures and text work together beautifully tointroduce facts about bird migration in this new addition to theLet's-Read-and-Find-Out Science series. Richly coloreddouble-spread artwork shows birds and children in a common habitatbefore focusing on birds themselves, in nests and on the wing. Thecrisply delivered accompanying text, larded with specific examples,delves into some of the tantalizing mysteries that surround birds'twice-yearly pilgrimage. Several maps are used to give children asense of distances traveled, and because so many differentvarieties of birds are shown, always clearly labeled, children canuse the book as a sort of informal spotter's guide.
