Where are birds in the greatest variety and numbers ? In the 

 Torrid Zone. 



What proportion of birds in North America migrate? More 

 than half. 



Why do they leave in the fall ? Partly because of the disappear- 

 ance of seeds, fruits, and insects which formed their food. ( There are 

 other reasons which are too mysterious for man to flnd ouf.)
