Show GO SOUTH TO SEEK FOOD Hunger, Not Cold, Forces Birds to Migrate Mi-grate From Northern Climates to the Warmer. If birds could store food for the win ter few would need to migrate. It Is hunger nnd not cold or darkness which drives them In multitudes every autumn au-tumn to more temperate climes. Certain Cer-tain privileged species can II ml food for themselves and t..elr young even lu midwinter In northern climates; and so fur from flocking Into the South when autumn calls, they choose the coldest months of the year for their breeding season. Young crovihills are fed on the seeds of pine cones, Wrenched out by the old birds' twisted beaks; and since rlc pine cones are plentiful In winter, crossbills begin to nest In Kugtand In December nnd Jan uary. Many birds, however, to find their dally food must innke n tremendous Journey Into the opposite temperate tone. The American golden plover travels nbout 10,000 miles encli year from its breeding grounds on the arctic arc-tic const of Canada to tho plains of Argentlnn nnd bnck. Swallows lu England Eng-land and Scotland have been marked at tho nest and 'identified In British South Africa few mouths lutcr. Such Journeys make modern human travel seem small; and they havo been pop formed for countless generations or bird life, wince the passing of the Inst glacial age. Christian Science Monl tor. |
