[Objective]Vigilance behavior is one of the important anti-predatory strategies for animals.The chirping of plateau pika is an important component of its vigilance behavior.Clarifying plateau pika's alert is of great significance for understanding plateau pika's survival strategy and enriching rodent voice communication research.[Method]In this study,20 adult plateau pikas,including 15 males and 5 females,were selected from the distribution area of plateau pika in Xiahe County,Gansu Province in 2021.They were captured,color marked and released.The Shotgun Microphones and camera were used to record the chirping sound and accompanying behavior,and the alarm call was identified.Adobe Audit 2020 was used to analyze the characteristics of its alarm call signal.[Result]The re-sults showed that:(1)Both male and female individuals of plateau pika could emit alarm call,which belonged to short sound.After the alarm call was issued,other individuals showed vigilance behavior of stopping feeding and look-ing around.(2)The alarm call tone is composed of one syllable and lasts 0.1～0.3s.(3)Under different distur-bances obtained under natural and remote control model interference,the alert call characteristics of plateau pika are different.After playing back the alarm calls with two different sound characteristics in the field,the plateau pika can be observed to make alert behavior responses.[Conclusion]Therefore,the plateau pika can use acoustic signals to transmit risk information.Its alarm call is a very short call,and there are differences in the alarm call under different risk levels.
