Beyond The Tortoise and The Hare
A songbird can fly about three times as fast as the silver Y moth over short distances. But during long-distance seasonal migrations, moths travel just as fast as birds, say scientists from Sweden's Lund University and elsewhere. They tracked birds and moths using radar and found that both averaged 18 to 40 miles per hour. The moth's trick: it waited for favorable tail winds or sought altitudes with fast-moving air. The bird's edge: it flew in most conditions.
