How Do Birds Find Their Way? (Let’s Read and Find Out) 自然科学启蒙2：鸟儿会迷路么？ISBN

　　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.
　　Ages 4-8. Pictures and text work together beautifully to
introduce facts about bird migration in this new addition to the
Let’s-Read-and-Find-Out Science series. Richly colored
double-spread artwork shows birds and children in a common habitat
before focusing on birds themselves, in nests and on the wing. The
crisply 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 a
sense of distances traveled, and because so many different
varieties of birds are shown, always clearly labeled, children can
use the book as a sort of informal spotter’s guide.
