MAP SHOWING SUMMER AND WINTER HOMES OE THE BIRD THAT HATES DARKNESS 



The summer home of the Arctic tern is along the Arctic coast of North America; its 

 winter home within the Antarctic Circle, 11,000 miles away. During eight months of the year 

 the bird lives where the sun does not go below the horizon. The track of the tern in its 

 round journey of 22,000 miles is unknown (see page 359).
