an object, substance, or technique that repels, or drives an animal away. There are several kinds of repellents: scare devices; chemical repellents; and guard animals. Most repellents frighten an animal away from a site or make the desired object (such as a crop or nesting site) intolerable by making it smell or taste nasty, or feel bad to the touch. Animals may be "hazed," or driven away from a site when chased by predators (dogs, falcons) or vehicles (radio-controlled planes, boats). Scare devices include mylar tape, strobe lights, models of predators, and "scare-eye" balloons; noisemakers, such as propane cannons, bangers, clappers, crackers, and distress calls. For details, see chapter five.
