The
purpose of this research was to determine if L98 (Tsuxiit / Luna)
emits vocal calls. During daily monitoring procedures, underwater
recordings of L98 were made in Nootka Sound from September to
October 2003. Acoustic analysis reveals L98 using three main calls
in Nootka Sound (L98_1, L98_2, L98_3). L98 can be identified by
frequent use of two calls (L98_1 and L98_3). These calls are comparative
to southern resident killer whale common calls S1 and S19 of K
and L pod respectively. The L2 matriline have been known to use
these calls. This research and baseline data on southern resident
killer whale isolated call behaviour, could further studies on
killer whale communication. |
