Avian Repellents: Options, Modes Of Action, And Economic Considerations, J. Russell Mason, Larry Clark
National Wildlife Research Center Repellents Conference 1995
The present manuscript considers visual, auditory, tactile, chemosensory, and physiologic repellents currently available for use in the United States. Discussion of tactile, chemosensory, and physiologic repellents is emphasized for three reasons. First, these products are preferred by users. Second, application of these substances is regulated by state and federal agencies. Third, only four active ingredients are legally available at the present time. This lack reflects difficulties in obtaining regulatory approval and limited market size.

Great Plains Wildlife Damage Control Workshop Proceedings
Ripening field corn lost to wildlife was measured in fall 1993 in 10 midwestern states that have produced 83% of the field corn in the United States over the past 10 years. Sampling of damage was stratified by producer expectation of likely wildlife damage or unlikely wildlife damage. Damage was assessed immediately before harvest. Two plots that measured 4.5 m x 2 rows were assessed in each selected field. Of assessed fields, wildlife damage was present in 340 of 1,259 (27.0%) likely damaged fields and 108 of 1,243 (8.7%) unlikely damaged fields. As a percentage of harvested production, birds (Aves) …
