Effect Of Primary And Secondary Repellents On European Starlings: An Initial Assessment, Roger W. Sayre, Larry Clark
Effect Of Primary And Secondary Repellents On European Starlings: An Initial Assessment, Roger W. Sayre, Larry Clark
USDA Wildlife Services: Staff Publications
Wildlife managers need chemical repellents that are effective at deterring damage by birds, but these repellents must be environmentally and toxicologically safe. The number of commercially available bird repellents has been reduced because of concerns about environmental safety. Currently, there are 2 categories of avian repellents. Chemicals that are reflexively avoided by birds because they irritate the peripheral chemical senses are referred to as primary repellents. Chemicals that cause gastrointestinal illness and learned avoidance of ancillary sensory cues that are paired with the illness are known as secondary repellents. Secondary repellents most often identified as the most effective avian repellents …
