THE TRAVELS OF BIRDS 



Argentina, nearly eight thousand miles from 

 their nesting ground. Here they remain for 

 about four times as long as they do in their nest- 

 ing resort before beginning their northward 

 journey. 



The path they select in the spring makes the 

 Golden Plover's migration route one of the most 

 puzzling things in bird migration. They do not 

 return to the Arctic Regions over the road by 

 which they came from them, but take a wholly 

 different course. This leads them first to north- 

 western South America whence they go through 

 Central America, or over the Caribbean Sea to 

 the Gulf of Mexico. They then cross the Gulf,

 migrates northward up the Mississippi Valley, 

 and southward along the Atlantic coast. 



The Black Tern evidently follows a similar
