HOW DOES THE PLOVER FIND ITS W.\Y EVERY TO THE LITTLE IIA- WAIIAN ISLANDS, 2,400 MILKS ACROSS THE OCEAN? The above gives a probable and fairlvsatisfactory explanation of the origin ofthe present migration route of the goldenplover over the Atlantic Ocean. But thisis a very simple problem compared withthat presented by the Pacific goldenI)lover. The Hawaiian Islands are inthe middle of the Pacific (^cean. miles from California on the miles from Alaska on the north,and ,v7();> niik-s from japan to the west. 188 orR GREATEST MAP SHOWING THE EVOLUTION OF THE PRESENT MIGRATION ROUTE OE THE GOLDEN PLOVER (SEE PAGE 187) Golden plovers in considerable numbersfly each fall the 2,400 miles across anislandless sea from Alaska to Hawaii,spend the winter there, and fly backagain the next spring to nest in how did they first find their way toHawaii? It is not to be supposed that any birdswould deliberately strike out over un-known seas hunting for a new winterhome. It is scarcely more probable that,even if a large flock was caught in astorm and carried far out of its courseto the Hawaiian shores, the birds wouldchange in a single season habits of count-less generations and start at once a radi-cally new migration route. It has alreadybeen said that present migration routesare evolutions—age-long modifications ofother routes. The problem, then, is tofind some migration route from whichthe golden plovers present Hawaiian-Alask
