The Travels of Birds
by Frank M. Chapman
Publisher: D Appleton & Company 1916
Number of pages: 160
Birds are the greatest travelers in the world. The bird traveler asks help from no one. He has no use for locomotives, automobiles or steamships. He carries no chart and no compass, and he can go with ease to parts of the world which it took man many years to reach, and to some parts of the world which still are unknown to man.
