“…The present study found that plateau pikas can transmit alert information by emitting a very short chirp with a duration of less than 2 s. This was uncovered through observation and analysis, and then the function of this short chirp was verified experimentally. Our result differed from the analysis by Hua [12] with regard to plateau pikas' chirps, who concluded that alarm calls were long chirps. We found that vigilance behavior was always accompanied by a simultaneous short chirp.…”

“…However, with continuous advancement in research techniques, it is now clear that audible signals are particularly important for social and gregarious rodents [11]. They play an important role in territorial behavior, courtship, warning and other activities by emitting different sounds [12]. For example, Pearson's tuco-tuco (Ctenomys pearsoni) will frequently make a unique courtship sound in the initial stage of reproduction [13]; when gerbils (Rhombomys opimus) are frightened, they will emit a short whistle to alarm other individuals [14]; and squirrels of different species can emit different alarm calls, with some even possessing a variety of different alarm sounds to transfer information about different predators [15].…”

“…He et al [23] analyzed the acoustic characteristics of calls in plateau pikas and speculated on their biological meaning, ranging from courtship, to raising alarm, to scaring away predators. In another study, Hua et al [12] concentrated on the temporal distribution of long calls and their influencing factors in male plateau pikas. In addition, when Zhang et al [24] studied the predation risk of plateau pikas, it was found that they were highly sensitive to predator "voices" and the distressed screams of other plateau pikas.…”

Acoustic communication plays a vital role in passing or sharing information between individuals. Identifying the biological meaning of vocal signals is crucial in understanding the survival strategies of animals. However, there are many challenges in identifying the true meaning of such signals. The plateau pika (Ochotona curzoniae) is a call-producing mammal endemic to the Qinghai–Tibet plateau (QTP) and considered a keystone species owing to its multiple benefits in alpine rangeland ecosystems. Previous studies have shown that plateau pikas emit alarm calls as part of their daily activities. However, only field observations have been used to identify these alarm calls of the plateau pika, with no attempts at using playback experiments. Here, we report the alarm calling of plateau pikas through field observations as well as simulated predator and playback experiments in the Eastern QTP from 2021 to 2022. We found that both female and male adults emitted alarm calls, the signals of which comprised only one syllable, with a duration of 0.1–0.3 s. There were no differences in the characteristics between the observed alarm calls and those made in response to the simulated predator. The duration of the alarm call response varied with altitude, with plateau pikas living at higher altitudes responding at shorter durations than those at lower altitudes.
