商品簡介 |
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. |
