Book excerpt: Excerpt from Birds That Eat the Cotton Boll Weevil: A Report of Progress The problem of controlling the ravages of the cotton boll weevil in the United States is of such moment that it is being studied by the Department of Agriculture from a number of different standpoints. One of these is the relation of birds to the weevil. Accurate informa tion as to the value of our native birds as destroyers of this pest is of considerable importance to the cotton grower, but such information can be obtained only by means of careful and continued observation in the field, supplemented by study of the stomach contents of the birds. Field observations alone, unverified by stomach examinations, have proved unreliable. Birds may be observed picking insects from cotton plants, but it does not follow that the insects are boll weevils; nor is the statement that boll weevils have been found in birds' stomachs, if made by persons unaccustomed to the identification of insects, to be accepted as conclusive. Insect remains in a bird's stomach are nearly always in a more or less disintegrated condition, so that identification of the species is difficult and requires the services of a specialist. Investigation of the problem was begun by the Biological Survey in the fall of 1904 under the direction of Vernon Bailey. The results of this study, with a summary of work done by the Bureau of Entomology, were published in a special bulletin by Mr. Bailey in Stomachs of 38 species of birds were examined, and 11 species were found to have eaten boll weevils. The number of species known to feed on the weevil was increased to 20. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
