Savvy whitetail hunters know the different vocalizations deer make and how to use products mimicking those sounds to bolster their hunting success.

Sound travels differently through open fields than the woods. When deer eat up bushes, small trees and other forest plants, it affects the transmission of bird calls and other natural sounds.

Rattling, calling, and scent control used to be considered completely idiotic tactics for hunting deer. Now, they're mainstays.

A study that analyzed how deer react to predator sounds concluded that whitetails fear humans more than wolves, coyotes, dogs, and cougars.
