When a Predator Pauses: A Rare Moment at the Waterhole

A waterhole in its last stages offers no immediate rush: the lion moves slowly, while the antelope stays nearby, motionless and watching, with neither taking any action. Instead of initiating a hunt, the two animals continue staying in their places, drinking and observing each other. This seems to run contrary to the basic laws regulating the relationship between predators and prey.
However, as research conducted for Biological Conservation suggests, it is only natural considering the environmental factors influencing such an encounter. As water becomes scarce in times of drought, animals find themselves forced to get closer than normal, creating opportunities for uncommon actions. In such a situation, animals rely more on the assessment of circumstances rather than on instincts when deciding on any specific behavior.
Interactions are affected because of resource pressure
The waterholes represent survival sites for all the species involved, with conflicting needs. While it is normal for the prey species to avoid the predators in terms of timing and distance, the environment may upset this equilibrium. There is evidence that environmental stress affects predator-prey avoidance behavior, making it possible for species that do not come into contact during normal circumstances to overlap in their activities. The predator may be forced to restrain its actions due to a lack of certainty over its success, in order to preserve energy. On the other hand, the prey may be willing to take chances as far as risk is concerned for reasons of survival.
Adaptation and context
The behavioral response to shared resources is not only determined by the immediate need to survive. Chemical markers, the environment, and past experience all factor into the animal responses. Scientists have shown that animals can recognize potential danger through the slightest signs and modify their behavior based on this information. Other factors, such as human influence, which may result in the destruction of a habitat or reduced access to water, add to the intensity of such encounters.
Such instances will not alter the dynamics between predators and prey. They demonstrate, however, how adaptable these dynamics can be and how survival requires time, caution, and adaptation.
