The purpose of this study was to determine the relative importance of vision, audition, and olfaction to coyotes (Canis latrans) hunting under various environmental conditions. The time durations for four coyotes to locate rabbits within a large outdoor enclosure were determined, with the visual, auditory, and olfactory stimuli emitted by the rabbits blocked individually, in pairs, and altogether. Visual stimuli were eliminated by conducting the tests only during sub-threshold nocturnal conditions. Auditory stimuli were eliminated by killing the rabbits immediately prior to a test. Olfactory stimuli were eliminated by inducing anosmia in each coyote through irrigation of the nasal mucosa with a 10% zinc sulphate solution. The relative importance of these three senses in decreasing order was concluded to be: vision, olfaction, and audition.
本研究的目的是确定视觉、听觉和嗅觉对郊狼（犬属）在各种环境条件下捕猎的相对重要性。测定了四只郊狼在一个大型户外围栏内定位兔子的时间，分别单独、成对以及同时阻断兔子发出的视觉、听觉和嗅觉刺激。视觉刺激通过仅在阈下夜间条件下进行测试来消除。听觉刺激通过在测试前立即杀死兔子来消除。嗅觉刺激通过用10%硫酸锌溶液冲洗每只郊狼的鼻粘膜诱导嗅觉丧失来消除。得出这三种感官的相对重要性由高到低依次为：视觉、嗅觉和听觉。
