"Ultrasonic calls, too high for the human ear to detect, convey a wealth of information across the rodent's territory."
"In the African desert, wild mice 'sing' tunes that don't travel far but help the animals to tell neighbours from strangers, researchers have found."
Wild African desert mice produce ultrasonic vocalizations that are inaudible to humans. These high-frequency calls convey a wealth of information across individual territories. The vocalizations have limited propagation and do not travel far, restricting communication to nearby areas. Within this short range, the tunes enable animals to distinguish neighbours from strangers, supporting local social recognition and territorial interactions. The high-frequency, localized signaling likely reduces eavesdropping and helps maintain boundaries between neighboring animals in the arid environment. Ultrasonic communication thus functions as an effective, short-range information system among desert rodents.
