INDEX TO PAPERS RELATING TO FOOD OF BIRDS. 29 



lent graphic representation, by means of sectors of a circle, of the proportions 

 of various items in the food of birds. Part of these diagrams are made much 

 more effective by the addition of small figures illustrating a typical member of 

 a group within its particular sector. The article includes an estimate of the 

 value of the crops saved daily by the destruction of locusts by nestling birds 

 in eastern Nebraska during the invasions of Rocky Mountain locusts. 



19O1. 



Two vanishing game birds the woodcock and the wood duck. By 

 A. K. Fisher, pp. 447-458. pis. 63-64. figs. 37-39 (1 map). 

 Brief notes on the food of each of these species are given. 



19OS. 



Audubon societies in relation to the farmer. By Henry Oldys. 

 pp. 205-218. pis. 21-22. figs. 11-12 (maps). 



This article includes a general statement of the economic value of birds, 

 together with a few specific notes on bird food. 



19O3. 



The economic value of the bobwhite. By Sylvester D. Judd, Ph. D. 

 pp. 193-204. pi. 16 (colored). 



This very comprehensive account of the bobwhite includes a statement of its 

 range and general habits; treats the bobwhite as a weed and insect destroyer, 

 as an article of food, and as an object of sport ; and discusses measures for the 

 preservation of the species. A very full list of the seeds, fruits, insects, and 

 other invertebrates eaten by the bird concludes the article. 



It is now stated upon reliable authority that the record quoted on p. 196 to 

 the effect that 47 cotton-boll weevils were eaten by a bobwhite in one morning 

 is based on observations upon a captive bird. The statement has no value, 

 therefore, as an indication of the relation of bobwhite to the boll weevil under 

 normal conditions.

Beal. pp. 241-254.

 introduction of injurious species.
