NOTES: adult female and later an adult male with tail-flagging periods and caller sex verbally noted on tape. Her initial tail-flagging and associated "rough grunts" isfollowed by several other group members engaging in the tail-flagging display. It is typical for flagging and "rough-grunting" to began with one highly aroused individual and then be followed by several or many other group members all flagging. Tail flagging may be a mobbing display, though some researchers feel that is it more likely a "distraction display" (Dr. P.C. Wright, personal communication). No formal data exist to firmly answer this question.
NOTE GREAT "SHRIEKS" AT 6:38, 7:43, AND 8:14. Such "SHRIEKS" are given collectively by groups at dawn and dusk (in a chorus fashion) as well as by single spatially separated ("lost") individuals.
LNS NOTE: Unbroken cut with internal recordist announcement/handling noise gain change (MJA, 29 June 2005).
