Meeting of the Clans - Orca and Humpback Vocals!!! Near Telegraph Cove, BC CANADA
One of the most mind-blowing days I have ever had the privilege of experiencing on the water. Wild in the truest sense of the word as matrilines (family groups) of the northern resident (inshore fish-eating) orca population met near Telegraph Cove. The I15s (a G clan matriline) met up with the A36s, A34s, A30s, A8s, A23s and A25s (multiple A clan matrilines) = some 50 whales (I15s and maybe some A34s in this group). The ocean erupted with their vocalizations and, I believe, led to the humpbacks posturing and even vocalizing. Each northern "resident" (inshore fish-eating) matriline is acoustically distinct but the I15s really sound different than the As as they are more distantly related and have a different dialect. This is a direct correlation between acoustic similarity and relatedness. There are 3 dialect groups in the northern resident orca population - A, G and R. ©2013 Jackie Hildering; www.themarinedetective.ca
