26 INDEX TO PAPEKS EELATING TO FOOD OF BIRDS. 



191O. 



Eeport of the chief of the Bureau of Biological Survey. By H. W. 

 Henshaw. pp. 549-565. 



The economic topics dealt with in this report are as follows : Injury to timber 

 by woodpeckers, food of wild ducks and flycatchers, and birds in relation to the 

 gypsy and brown-tail moths. 



SCHEDULES. 



The series known as schedules, with one exception, consists of 

 blank forms for the recording of data. No. 4, devoted to questions 

 concerning the economic status of the English sparrow, is indexed. 



SCHEDULE 4. Schedule on the English sparrow (Passer domesticus). 

 By Dr. C. Hart Merriam [1 p., unnumbered, 1886]. 



Consists wholly of questions on the presence, abundance, relations to other 

 birds, food, and injurious habits of the English sparrow. 



YEARBOOKS. 



The Yearbook of the United States Department of Agriculture 

 had its origin in a desire to separate papers of a scientific character, 

 with which the annual reports were becoming burdened, from the 

 administrative reports of the various bureaus and divisions. The 

 first Yearbook, that for 1894, was issued in 1895 and this relation of 

 date of publication to date of volume holds throughout the series. 

 The Yearbook consists principally of special reports and papers 

 which are designed to interest and instruct. 



In the 17 volumes thus far issued (including 1910) the Biological 

 Survey has furnished 32 articles dealing to some degree with the 

 food of birds. 



1894. 



Hawks and owls as related to the farmer. By A. K. Fisher, M. D. 

 pp. 215-232. Pis. I-III. figs. 21-24. 



This article is a condensation of Bulletin 3 of the Biological Survey. It 

 contains lists of the wholly beneficial, chiefly beneficial, and harmful hawks 

 and owls, as well as those in which harmful and beneficial qualities about 

 balance. The food habits of 32 species are briefly reviewed. 



The crow blackbirds and their food. By F. E. L. Beal. pp. 233-248. 

 fig. 25. 



This is the most authoritative account of the food of any species of bird, 

 being based upon the examination of 2,258 stomach contents. The paper takes 

 account also of printed and communicated testimony on the food of the crow 

 blackbird. The grains and fruits eaten, animal food, and food of the young 

 are all carefully considered. Depredations on grain and various other in- 

 jurious traits are admitted, while on the other hand the birds are stated to do 

 incalculable good by destroying insects.
