 Previous to the publication of this paper little had been made public concern- 

 ing the destruction of scale insects by birds. Indeed, currency had been given

 upon the black olive scale, one of the most injurious species in the United States.

The relations between birds and insects. By F. E. L. Beal. pp. 

 343-350. 

 The principal points made in this paper are that birds are a very important 

 check upon insects aud that, their true function is not so much to destroy this or 

 that insect pest as it is to lessen the numbers of the insect tribe as a whole. 

 While the bulk of the paper consists of a general discussion of the relations 

 between birds and insects, definite notes on the food of a few species are given.
