THE TRAVELS OF BIRDS 



food is scarce at the north, we may hope to see 

 Crossbills, Redpolls, and even Pine Grosbeaks. 

 All these late arrivals will stay with us until 

 spring. By the ornithologist they are classed as 

 "Winter Visitants." 



Birds like the Golden Plover and Turnstone, 

 that have to cross two thousand or more miles 

 of ocean and are not believed to alight upon the 

 water, cannot, of course, rest by the way. But 

 the Warblers and other small birds that migrate 

 chiefly over land evidently rest for several days 

 after making an all-night flight. During this 

 time they may travel a little by day, as they 

 hunt insects from tree to tree, or if they have 

 happened to come down into some small piece 

 of woodland such as is found in city parks, they 

 may remain in the same place until they are 

 ready to continue their journey. 



While they are waiting they may be passed by 

 other birds of their own kind, and while these 

 birds are resting somewhere on ahead they may 

 in turn fly on ahead of them. An individual 

 bird may therefore fly four or five hundred miles
