- Abstract: Possum acoustic behaviour is complex and varies substantially, with some species having numerous calls used in various contexts, while other species are limited to one known vocalisation or non‐vocal sounds. Here, we report that the first known recording of Sulawesi bear cuscus ( Ailurops ursinus, 1824) acoustic behaviour and observations of associated behavioural displays. We observed an animal adopting a raised posture in apparent threat display and audio‐recorded the concurrent short, harsh sounds. The animal produced a 'chatter', composed of four notes given at short, regular intervals, followed by a series of 'clicks' given at longer and irregular intervals. We describe the frequency and temporal characteristics of these sounds. Clicks were variable in acoustic structure, possibly falling into three subtypes, and some clicks overlapped in acoustic features with individual chatter notes. Click and chatter notes were broadband and non‐tonal, and so appear to be non‐vocal sounds, produced by the mouth or tongue rather than larynx. Our observations and recording of A. ursinus contribute to the natural history of this poorly known and enigmatic species, that is currently threatened with extinction from illegal wildlife trade, hunting and deforestation.

Rekaman pertama perilaku akustik kuskus beruang Sulawesi (Ailurops ursinus). Hal ini berkontribusi pada sejarah alam dari spesies yang kurang dikenal dan penuh teka‐teki, yang saat ini terancam dari perdagangan ilegal satwa liar, perburuan dan penggundulan hutan Abstrak: Perilaku akustik possum bersifat kompleks dan sangat bervariasi, dengan beberapa spesies memiliki beragam panggilan yang digunakan dalam berbagai konteks, sementara spesies lain diketauhi terbatas pada satu suara vokalisasi atau non‐vokal. Di sini, kami melaporkan rekaman pertama yang diketahui dari perilaku akustik Kuskus beruang Sulawesi ( Ailurops ursinus, 1824) dan pengamatan dari tampilan perilaku terkait. Kami mengamati seekor hewan yang mengadopsi postur tubuh yang tampak seperti ancaman, dan merekam audio suara yang pendek dan kasar secara bersamaan. Hewan itu mengeluarkan "obrolan", terdiri dari empat nada yang diberikan secara singkat dan teratur, diikuti oleh serangkaian suara decak yang diberikan dengan interval yang lebih panjang dan tidak teratur. Kami menjelaskan frekuensi dan karakteristik temporal suara‐suara ini. Suara decak bervariasi dalam struktur akustik, mungkin terbagi dalam tiga sub‐jenis, dan beberapa suara decak tumpang tindih dalam fitur akustik dengan catatan obrolan individual. Nada decak dan obrolan adalah nada pita lebar dan non‐nada, sehingga tampak seperti suara non‐vokal, yang dihasilkan oleh mulut atau lidah daripada laring. Pengamatan dan pencatatan kami terhadap A. ursinus berkontribusi pada sejarah alami spesies yang kurang dikenal dan misterius ini, yang saat ini terancam punah karena perdagangan illegal satwa liar, perburuan dan penggundulan hutan.
