Whale Tails


Cover Image:
Orcas tail slapping in unison

An exciting part of whale watching is seeing the tails (called flukes) of whales coming out of the water as the animals dive. Some whales like to perform tail slaps, that is an animal will raise its tail out of the water and hit the water repeatedly with their tail creating a loud sound. It is thought that tail slapping could be a form of communication and it could be a form of play. Among the species of Cetaceans here in B.C., Humpback whales and Orca can be seen performing tail slaps occasionally.

There have been sightings of Transient Orca in Howe Sound, around Powell River, and in various inland waterways. Some Orca were reported further north along Johnstone Strait and remains unidentified, but possibly could be the Northern Resident Orca. A couple of Orca were also spotted close to shore in Victoria. Pacific White Sided Dolphins have been observed in small pods and in large pods, some numbering in the hundreds. Dall’s porpoises have appeared in many areas and some make a regular appearance in Toba Inlet. Dall’s porpoises have also been spotted in Georgia Strait off of Point Grey in Vancouver. Rounding our report are a few sightings of Humpback whales and Harbour porpoises.

WOWs works throught the year, so please continue to keep your eyes open, and report your sightings to us.

    Thar She Grows: A New Way to Tell a Gray Whale’s Age
    Hakai Magazine, BC
    Being able to accurately estimate an animal’s age is an important step in understanding the health of a population.
    If you see a gray whale cruising offshore, it’s fairly easy to guess, based on little more than its size, whether it’s an adult or a juvenile. But without digging through a dead whale’s earwax or examining its ovaries, determining age is surprisingly difficult.

    A Canadian researcher has now discovered a novel method to eyeball a gray whale’s age that is much less invasive than existing techniques. By analyzing the relationship between whales’ sizes and their ages, Selina Agbayani, a master’s student at the University of British Columbia (UBC) in Vancouver, has plotted growth curves that describe in detail how gray whales change in length and weight as they age….

    Vancouver Sun: Whale of a mystery: Local orcas three times more likely to die in even years
    VANCOUVERSUN
    Southern resident killer whales are three times more likely to die in even years than odd years, a pattern that cannot be explained by the widely accepted threats to their health.

    Successful orca births are also 50 per cent less frequent in even years than odd years over the past two decades, according to a study by researchers in Washington state….

    From the humpback to the Antarctic blue: why do whales sing? | The Independent
    INDEPENDENT
    Sometimes a whale just wants to change its tune. That’s one of the things researchers have learnt recently by eavesdropping on whales in several parts of the world and listening for changes in their pattern and pitch. Together, the new studies suggest that whales are not just whistling in the water, but constantly evolving a form of communication that we are only beginning to understand….
