The ‘thumbprint’ of each individual is in the pattern of the flukes.  No two are alike although they can have similarities.  The job of a fluke researcher is very labor intensive.  To date, there is no computer program that will compare photographs, or slides, of these animals.  There is a great need out there for someone to write such a program, similar to one that is used for human fingerprints.  The person who does come up with this program could be set for life, not to mention the eternal gratitude from every researcher and intern in this field.

Since the 1960s, this method has been used to determine who goes where.  In the North Pacific stock of humpback whales, which may now number about 20,000 animals, researchers know that about 60% of those who migrate head to Hawaii.  They tell us that 30% head down to Baja, California, and the remaining 10% to the islands south of Okinawa.  To obtain these photographs, researchers follow individuals around all day and take pictures of each dive, hoping to obtain that ‘perfect’ photo.  The photos are then placed into the database and someone later sits and compares all photos, some taken in each area.  From this method we also know of individuals who come to Hawaii and feed in Canadian waters.  Other Hawaiian whales are seen in SE Alaska and the Aleutian Islands.

Since we are out there whale watching nearly every day, there are animals that we have come to know over the years.  Sometimes it seems that they may recognize us as well.  It is not uncommon to have ‘friendly’ whales approach vessels.  We always like to ask “who watches whom?”.

Whale watching in the Hawaiian breeding grounds is an unforgettable and amazing experience that touches different people in various ways.  Some say it is a spiritual connection that keeps them returning during whale season.  Others say watching whales helps them to better understand these gentle giants.  Whatever the reason, I feel we all receive some sort of connection with wild animals.  Possibly it helps us stay grounded with who we really are and why we are here on this amazing planet.  Come to Hawaii and join us.  Get reconnected with your marine mammals.
