Discrete Calls of Solitary Southern Resident Killer Whale, Orcinus orca, L98 (Tsuxiit / Luna)

The purpose of this research was to determine if L98 (Tsuxiit / Luna) a wild solitary killer whale was emitting vocal calls. During daily monitoring procedures of the young four year old whale, underwater recordings were made in Nootka Sound from September to October 2003. Acoustic analysis revealed L98 using three main calls in Nootka Sound (L98_1, L98_2, L98_3). L98 could be identified by frequent use of two main calls (L98_1 and L98_3). These calls were comparative to Southern Resident killer whale calls S1 and S19 of K and L pod respectively. The L2 matriline (L98’s family) have been known to use both the S1 and S19 calls. This research provides information on isolated killer whale call behaviour and increases knowledge on vocal learning and communication.
