VOCAL COMMUNICATION



pant-hoot: This is consists of a series of loud calls which are rising and falling in pitch and often end in a scream (Nishida and Hiraiwa-Hasegawa, 1987). This call is most often given by males, but females may also give it (Nishida and Hiraiwa-Hasegawa, 1987). This call is given at abundant feeding sites, after smaller groups have been reunited after a few days, a response to loud calls, and as a response to charging display (Nishida and Hiraiwa-Hasegawa, 1987).

pant-grunt: This consists of a series of soft, low grunts (Nishida and Hiraiwa-Hasegawa, 1987). This is given by subordinate individuals to dominate ones as a response to dominance displays, such as the charging display (Nishida and Hiraiwa-Hasegawa, 1987).

wraaa: This call is given as a fear vocalization especially the fear of something strange (Estes, 1991).
