242 Roosevelt Wild Life Bulletin 



they often over-emphasize characters that are not apparent in the 

 field, and leave out the points concerning general appearance, habit, 

 and voice that are most useful there. I have attempted to describe 

 songs as accurately as is possible, without actually making definite 

 song records for each species, in the hope that the descriptions will 

 prove of value. These descriptions in most cases are not based on 

 study in the Allegany Park alone, but on investigations in various 

 other localities also. I had had some previous field experience with 

 all the species thus far found in the Park. My former acquaintance 

 with the Mourning Warbler, however, was decidedly meager and 

 did not include its song, while my previous observation of the 

 Cerulean Warbler had been made so long ago that it was now 

 almost like seeing and hearing a new bird. 



For the beginner I would suggest that this publication be com- 

 bined with some good general bird guide, and that no attempt be 

 made to use it alone, since other species besides those listed are 

 likely to be found in the Park. There are numerous good popular 

 bird guides, but I would particularly recommend Chapman's 

 "Handbook of birds of Eastern North America" (1914), or Hoff- 

 mann's " Guide to the Birds of New England and Eastern New 

 York" (1904). The former is the most complete and authoritative 

 guide that has been written, and is invaluable to one who intends to 

 take up serious ornithological study. The latter, the work of a close 

 and careful field student, contains many hints on habits, notes, or 

 differences between puzzling species that make it extremely useful 

 in the field. The Reed " Bird Guide, East of the Rockies " (1913) 

 has the advantage of small size, low price, and a colored portrait 

 of each species ; but the small size makes it impossible to include 

 much information, and in some copies the colorings are not' very 

 accurate. Eaton's " Birds of New York " (1910-1914) will also be 

 found most useful because of the local records and migration dates 

 for various parts of New York State, as well as the excellent and 

 almost complete set of colored plates. This work, however, is too 

 large and heavy for field use. 



For beginners I should like also to recommend what Silloway 

 has written on the subject of bird study in his " Guide to the Sum- 

 mer Birds of the Palisades Interstate Park" (1920, pp. 17-22). 

 Job's " How to Study Birds " (1910) is a delightful and most help- 

 ful book, especially for the would-be camera-hunter. Forbush's 

 "Useful Birds and their Protection" (1913) leads to an appre- 

 ciation of the economic value of birds and their role in nature. 

 Those who have developed a deeper interest in bird life and wild 

 life generally, and are concerned about its ultimate fate, will do 

 well to read Adams' " Suggestions for the Management of Wild 

 Life in the Allegany State Park" (1921).
