This entry in the Let's-Read-and-Find-Out series asks plenty of
questions in a brief, lucid text, urging readers to think about
what happens to birds in winter - how they return to their nesting
grounds year after year across continents and oceans, and how they
navigate by day, at night, and in fog. Gans (When Birds Change
Their Feathers, 1980, etc.) answers some questions - making clear
that there are still many mysteries in the field of ornithology -
and discusses how scientists learn about migration through
observation and experimentation. Appealing full-color illustrations
complement and extend the discussion: close-ups of familiar
neighborhood birds, some in unusually vivid plumage; dramatic views
of flight; and accessible maps of migration patterns. A solid
introduction to a fascinating topic and a welcome addition to the
series. (Kirkus Reviews)
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.
