- Ultrasound: Grey near can hear sounds at frequencies up to 100,000 Hz, while humans can only hear sounds up to 20,000 Hz. This allows them to hear the high-pitched squeaks and whistles of prey and predators.
- Infrasound: Grey near can also hear sounds at frequencies below 20 Hz, while humans can only hear sounds down to 20 Hz. This allows them to hear the low-rumbling sounds of storms and earthquakes.
- Directional hearing: Grey near have highly directional hearing, which means that they can accurately locate the source of a sound. This is important for hunting and predator avoidance.
In addition to being able to hear sounds at different frequencies, grey near also have a much greater hearing range than humans. They can hear sounds from up to 15 miles away, while humans can only hear sounds from up to about 1 mile away. This allows them to detect potential predators and prey from a much greater distance.
Grey near use their hearing to a number of important purposes, including:
- Hunting: Grey near rely on their hearing to locate prey. They can hear the sounds of prey moving through the forest, and they can even pinpoint the location of a prey animal by its vocalizations.
- Avoiding predators: Grey near also use their hearing to avoid predators. They can hear the sounds of predators approaching, and they can take evasive action to avoid being caught.
- Communicating: Grey near use vocalizations to communicate with each other. They can make sounds to warn of danger, to attract mates, and to coordinate hunting and foraging activities.
The hearing of grey near is a remarkable adaptation that helps them to survive in the wild. By being able to hear a wide range of sounds and from great distances, they can find prey, avoid predators, and communicate with each other.
