夜行性的動物傳達訊息時，氣味或聲音通常較視覺更為重要。白面鼯鼠為一種台灣夜行性哺乳動物，會頻繁地使用叫聲，但是其聲音與行為的關係尚不明確。本研究目的是藉由錄音分析配合行為觀察，探討白面鼯鼠的叫聲類型、使用狀況及可能功能。研究樣區位在阿里山光華村的次生林，於2012年3月至2013年2月，每月連續兩夜，針對樹間活動的白面鼯鼠錄音並紀錄其行為。結果顯示，白面鼯鼠全年皆頻繁的發出叫聲，晚上7-9點與清晨3-5點是兩段高峰期。鳴叫聲依據頻譜特徵可以區分為A、B、C、D四種類型。將周遭環境以及伴隨行為皆納入考慮後，發現每種叫聲類型皆可能發生在不同情況下，但根據出現的頻率，大致上可將不同類型聲音區別出不同功能，分為:單音型A叫聲為警戒音，多用於警戒人類(非同種類入侵者)；連續型A叫聲為社交叫聲，用於相伴活動的個體彼此聯繫；叫聲C為競爭叫聲，多用於同種間的競爭，像是雄鼠間競爭交配機會時；叫聲B與D功能則因樣本數不足無法推斷。叫聲類型A及B在繁殖季出現的次數高於非繁殖季。類型A的叫聲在雌鼠與雄鼠間無顯著差異，但在部分個體間有顯著差異，推測可能因為白面鼯鼠為獨居性之物種，故聲音中所涵蓋資訊不如社會性高之物種一般詳細。

Olfactory or vocal communication is usually more important than visual communication in exchanging information for nocturnal animals. The white-faced flying squirrel (Petaurista lena) is a nocturnal animal and frequently use calls to communicate. However, the relationship between their calls and behavior is not clear. The goals of this study were to describe their calls produced by the white-faced flying squirrel, understand the calling pattern and infer their functions by combining the data collected by call recording and context observation. The field works was conducted in a secondary broad-leaved forest in Guanghua Village, Chiayi County from March 2012 to February 2013. Their calls and accompanied behavior were recorded for two nights per month. The results showed that they called most frequently during 7-9 pm and 3-5 am. The calls were divided into four call types based on their acoustic characteristics. Some call types were associated with one or two contexts more frequency than the other. However, the calls have different functions, namely alarm, affiliative interaction and agonistic interaction. The call rates of call type A and B were significantly higher in reproductive season than non-reproductive season. The call type A were not significantly different between male and female but different among some individuals which possibly due to their low degree of sociality.
