Abstract
For more than a decade, personnel of the Section of Bird Damage Control at the Denver Wildlife Research Center have studied agricultural damage by birds. Much of their research has centered on evaluating damage reduction efforts, and in doing this, they have developed and used many damage appraisal methods. This paper outlines briefly those that have been published. It is hoped that these methods will provide other workers with a useful starting point for evaluating bird losses in other test situations or in other surveys over extensive areas. The reader is cautioned, however, that bird damage appraisal is very complex, and in planning sampling designs, the advice of a good agricultural statistician, or at least attention to a good statistical textbook, is important to prevent a wasted effort.
