Abstract
The present paper is a report on an intensive ornithological survey of a typical section of prairie farm land in northwestern Iowa. In making the survey several objects were in view. Besides merely making a census, it was hoped that some light might be thrown on the relation of birds to various crops, the effect of constant tillage on bird life, etc. It was thought that the exact data accumulated now would furnish a basis for comparison at a future time. With some such means of measuring the actual increase or decrease of the bird population, we will be in a better position to determine the problems of our bird life.
