How do mice communicate with each other? - briefly

Mice exchange information through ultrasonic vocalizations, chemical cues such as pheromones and urine markings, and tactile signals via whisker and body contact. These modalities convey territory, reproductive status, and alarm signals.

How do mice communicate with each other? - in detail

Mice rely on several sensory channels to exchange information.

Ultrasonic vocalizations (USVs) are emitted at frequencies above human hearing, ranging from 30 to 110 kHz. Pup distress calls peak around 40 kHz, prompting maternal retrieval. Adult males produce broadband USVs during courtship, while aggressive encounters trigger rapid, low‑duration calls that signal threat. These sounds are generated by the larynx and modulated by airflow, allowing precise timing and amplitude control.

Chemical signaling dominates territorial and reproductive communication. Urine, feces, and glandular secretions contain volatile and non‑volatile pheromones. Major urinary proteins bind odorants, extending detection time. Males deposit scent marks to delineate home ranges; females assess male quality through the composition of these marks. Mother‑pup interactions also involve pheromonal cues that synchronize nursing cycles.

Tactile contact conveys social status and reinforces bonds. Whisker brushing, grooming, and nose‑to‑nose touches transmit kinesthetic feedback that regulates hierarchy. Dominant individuals receive more frequent grooming, reinforcing their position.

Visual cues are limited but not insignificant. Mice detect movement and contrast using a dichromatic visual system. During nocturnal activity, rapid body posture changes and ear orientation serve as short‑range signals, especially in confined spaces.

Auditory, olfactory, tactile, and visual modalities integrate to produce a multimodal communication network. Context‑dependent weighting of each channel enables mice to coordinate foraging, predator avoidance, mating, and group cohesion.
