329B (RB 2006)

The northern resident killer whales were heard beach-rubbing, calling, and echolocating at the Main rubbing beach in the Robson Bight (Michael Bigg) Ecological Reserve, Vancouver Island BC.  The Orcalab 329B recording from August 28, 2006, begins at 07:18 and ends at 07:56.  A total of 41 repertoire calls were identified.  The main call used was N23 (30%), Pings (9%) from the I15 matriline, and N4 (5%).  Many other calls were varied from their discrete structure, whistles, and disordered vocal noise was heard during this social behaviour.
