Hypothesis
It is unclear if and when ultrasonic vocalizations (USVs) are produced by Peromyscus mice in the wild and how they function in natural habitats.
Conclusion
The discovery of ultrasonic vocalizations produced by Peromyscus in the wild highlights an important aspect of their behavior and opens new avenues for research.
Supporting Evidence
- 65 unique ultrasonic vocalization phrases were recorded from Peromyscus over 6 nights.
- The vocalizations represent 7 different motifs.
- Considerable variation in acoustic characteristics suggests individual and contextual variation in ultrasound production.
Takeaway
Researchers recorded sounds made by wild mice called Peromyscus, showing that they can communicate using special high-pitched noises.
Methodology
The study involved passive recording of ultrasonic vocalizations from two species of Peromyscus over six nights using a grid of microphones.
Limitations
The study was limited to two species and the recordings were made over a short period.
Participant Demographics
The study focused on two species of Peromyscus: P. californicus and P. boylii.
