Make Friends with Nature's 

 Feathered Wards in 



The Book of Birds 



200 Pages, Illuminated with 250 Matchless Subjects in Full Colors, 45 Illustrations 

 in Black and White, and 13 Striking Charts and Maps 

 A HOLIDAY GIFT OF PERMANENT VALUE 



No other Nature-book ever published at a moderate price equals The Book of Birds in 

 the beauty of its illustrations, the fascinating quality of its authoritative text, and the 

 charming intimacy with which it introduces the reader to shy Friends of Forest and Country- 

 side, Seashore and Upland. 



The three principal divisions of this beautiful book are the contribution of the gifted 

 ornithologist and facile author, Henry W. Henshaw, formerly Chief of the United States 

 Biological Surve}'. Dr. Henshaw possesses to a marked degree the rare faculty of de- 

 scribing the haunts and habits of Nature's wild creatures with the ease and grace of the 

 born story-teller and with the insight and knowledge of the scientist equipped by wide 

 experience and exhaustive research. And no author has ever had a more gifted or more 

 sympathetic illustrating collaborator than has Dr. Henshaw in the noted naturalist-artist, 

 Louis Agassiz Fuertes, whose 250 bird portraits, reproduced in full colors in this superb 

 volume, have preserved with wonderful fidelity not merely the richness of tint in plumage 

 but the animation and the personality, so to speak, of each subject. 



An engaging chapter is contributed by F. H. Kennard on "Encouraging Birds Around the Home." 

 Mr. Kennard persuades the reader to become a conserver of bird life, whether he be the possessor of a 

 great estate or the owner of a window-sill. 



That mysterious impulse which Nature has implanted in so many of her creatures — the migrating 

 instinct — is the subject of a wonderful chapter by Professor Wells W. Cooke. 



George Shiras, 3rd, noted as a traveler and naturalist and as the inventor of a method whereby birds 

 and wild animals make their own portraits, gives a delightful account of photographing wild birds with a 

 flashlight camera. 



The Book of Birds is a gift to delight the naturalist who can spend days in the forest, the business 

 man who has only an occasional hour in the woods, or the man or woman whose sole acquaintance with 

 birds is made in the city parks. Placed in the hand of a boy or girl, it will inculcate an imperishable 

 love of Nature and Nature's winged children.
