We report on three interactions between long-tailed weasels (Mustela frenata) and Neotropical singing mice (Scotinomys). Our observations suggest that weasels are potential acoustically-orienting predators of singing mice. We speculate that differences in pressure from eavesdropping by weasels may contribute to differences in length and complexity of songs between sister species of Neotropical singing mice.
