What phenomenon occurs when deer react to the sound of a bow being drawn?

When deer react to the sound of a bow being drawn, this is referred to as "jumping the string." This phenomenon happens because deer, being highly attuned to sounds in their environment, often instinctively react to the noise of the bowstring releasing.

When a deer hears the sound, its natural reaction is to quickly jump away from the source of the noise, which can cause it to move out of the path of an arrow that is fired shortly after the bow is drawn. This can lead to missed shots, as the timing of the bow draw and the release can coincide with the deer's movement. Understanding this behavior is crucial for bow hunters to improve their shot accuracy and enhance their hunting effectiveness.

The other options, while they may describe reactions or behaviors related to hunting or being startled, do not accurately characterize the specific action of a deer responding to the sound of the bowstring.
