Abstract: | Summary Further analysis of radar tracks of migrating birds over the Atlantic Ocean (Larkin et al., 1979) indicates that birds sometimes fly at lower air speeds when winds are in the direction of flight than in crosswinds or head winds. The birds are able to estimate wind direction over open ocean by a mechanism which is presently open to speculation. |
