Abstract

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.

Reportamos tres interacciones entre la comadreja de cola larga (Mustela frenata) y los ratones cantores neotropicales (Scotinomys). Nuestras observaciones sugieren que las comadrejas potencialmente escuchan las vocalizaciones y así favorecen la depredación de estos ratones. Especulamos que diferencias en la presión de escuchar subrepticiamente por comadrejas pueden contribuir a las diferencias en duración y complejidad de la vocalización entre especies hermanas de los ratones cantores neotropicales.
