Abstract

Much has been done, during the past few years, in determining the food habits of the various species of birds by means of stomach examinations. With a sufficient number of specimens, this method should give accurate information. Because of the time and patience required, and the difficulties to be overcome, little has been done by means of personal observation of the individuals in the field. During the past few years, it has been a matter of considerable interest to me, to follow up the reports of laboratory examinations of stomachs by personal observation, especially of the birds of prey.
