378 THE STRUCTURE AND LIFE OF BIRDS ch. XIV 



It is very remarkable that the study of birds, of all 

 animals the greatest wanderers, should have laid the 

 foundation of animal geography. Though the subject 

 of the geographical distribution of birds is one of 

 great interest, a detailed account of it is beyond the 

 scope of this book. It is only necessary to make it 

 clear that it must be carefully distinguished from 

 migration. The reader is referred to the article in 

 Professor Newton's Dictionary of Birds.
