Use loud noises to deter predation of livestock by mammals to reduce human-wildlife conflict
A replicated, controlled study on captive animals in Utah, USA (Shivik & Martin 2000) found that playing loud noises deterred consumption of food by coyotes Canis latrans. Six of 14 coyote pairs did not eat food while loud noises were playing repeatedly, whilst all seven coyotes pairs not played loud noises ate their food. Food consumption was reduced if loud noises were activated solely when coyotes approached food. Twenty-one pairs of coyotes were held in 0.1-ha pens. An alarm was suspended 2 m above the door to the pen, where 100 g of food was positioned. For seven coyote pairs, the alarm sounded every 7–9 seconds for an hour. For seven more pairs, it activated solely when they approached the food. For seven further coyote pairs, it was not activated. Behaviour of coyotes was observed for one hour.
