the well being of the various species. Long before the white man 
came to America the birds had established their seasonal lanes of mi- 
gration throughout the Western Hemisphere, as here outlined. The 
economic, inspirational, and esthetic values of these migratory species 
dictate that they be permitted to continue their long-accustomed and 
still mysterious habits of migration from clime to clime.

4 Since almost every faunal paper on birds has a bearing on the subject of migration, only a few can be 
listed in this publication. Those included were selected to aid the student wishing to pursue the subject 
further and to cover not only all cited in the text but also others consulted and used in its preparation.
