| We studied the effectiveness of electronic deer whistles in scaring away sika deer that are likely to run onto roads, resulting in accidents.

To assess the effectiveness of the whistles in alerting deer, the deer's reactions to the whistles were observed by blowing the whistle from a fixed place that is visible to the deer when they appear by the roadside. For the control sample, deer's behavior when no whistle was blown was observed. When no whistle was blown, 51% of the deer were on alert... |
