The food of Australian birds, J. B. Clkland et ai.. (Dept. Agr. N. 8. Wales, 

 Soi. Bui. 15 (1918), pp. 112). — In the present bulletin an analysis is made of 

 all available data on the food of wild birds in Australia. It includes the re- 

 sults of examinations, made during the course of control work with the blowfly 

 pest of sheep, of all birds in the sheep-breeding districts which might play a 

 possible part In order to meet all needs the information has been arrant sd 

 In several ways, including (1) a short summary of the food of and a verdict 

 on various birds or groups of birds, the most important being taken first, and 

 (2) lists indicating the birds which feed on particular kinds of food of more 

 or less economic importance- 

 Appendix 1 consists of a tabulated examination of the contents of the 

 stomachs and crops of each species of bird examined, full details being given 

 of the animal and vegetable food with remarks appended opposite the species 

 amplifying these details. Appendixes 2 and 3 consist of tabulated examinations 

 of the contents of stomachs and crops of the individual Australian birds, etc., 

 examined, from which appendix 1 was compiled. 



The English sparrow and starliDg were found to do much more harm than 

 good, neither apparently playing any definite part in the control of the blowlly 

 pest. The crow, while doing marked harm at times, is undoubtedly of decided 

 value on other occasions, ami by destroying dead carcasses tends to prevent 

 the multiplication of blowflies. Of the large number of other species examined, 

 with one or two notorious exceptions, the vast majority serve a more or less 

 definitely useful purpose in maintaining the balance of nature as regards the 

 various species of insects. Only a few, however, have been found to feed on 

 blowflies, and these do so only occasionally and play no definite part in con- 

 trolling this pest.

Maggot-infested birds, W. W. Arnold (Auk, 36 (1919), No. 1, pp. 147, 148).— 

 This note relates to the infestation of the smaller birds, including yellow wnr- 

 blers, goldfinches, house finches, horned larks, vireos, and house sparrows, in the 

 vicinity of Colorado Springs, Colo., by ProtocaUiphnrn azurea. "A few western 

 meadowlarks have been brought to me, two specimens, fledglings, yielding 100 

 worms, their bodies presenting the appearance of having been struck by a load 

 of shot. The largest number of these worm-infested creatures come from the 

 homes of the house sparrow."
