| Signal of predators and competitors, as well as the existence of human disturbances, can modify the behavioral responses of carnivores such as the European mink. These responses involve decisions that consider the costs and benefits of implementing certain behaviors. This trade-off may be affected in captive animals, due to the absence of threats, restraining some behaviors that would otherwise be instinctively executed in the natural habitat. The objective of this study was to determine the variation in the surveillance rate of 25 European minks, observing their behavioral responses by simulating an intraspecific encounter (visual signal: without and with a mirror), the presence of a potential predator (olfactory signal: owl and dog feces) and an anthropic threat (acoustic signal: traffic noise and community noise caused by human voices). Both sexes decreased the rate in the presence of a mirror as it was a direct visual signal. Likewise, the rate drastically decreased during community noise caused by human voices in both sexes probably due to habituation to roads, but not to a high human presence. The surveillance rate decreased in the presence of predator feces and road traffic noise before the mirror. However, this one was no relevant during the human voices | |
