For red foxes, having great hearing is important. It’s the main way they are able to detect various prey, like rodents. During the winter, when the prey is under the snowpack. The fox will stalk their prey with their hearing, following the unsuspected prey before pouncing on them. They are able to hear low-frequency sounds made by rodents underground, such as rustling, squeaking, scratching and chattering. Other animals are not able to hear some of these sounds, but thanks to a chamber in their eardrums of the fox, that echoes the tiniest of sounds. Foxes can hear them from over 100 feet away. Underground or hidden noises from 20 to 25 feet away. It’s the same distance for me when someone is unwrapping a chocolate bar.
