August 10, 2023, 3:30 - Celebrations with the T-party
Today we saw a T-party consisting of the T002Cs, T037s and T137s travelling together in Trincomali Channel, close to Porlier Pass. All the whales there today were:
T002C Tasu (1989)
T002C1 Rocky (2002)
T002C3 Lucy (2011)
T002C5 Zippy (2020)
T034 Grace (~1969)
T034A Pachamama (2007)
T034A1 (2019)
T034B (2017)
T037 Rocky III (1979)
T037B Harald (1998)
T037B1 Lance (2012)
T037B3 (2022)
T137 Loon (~1984)
T137A Jack (2002)
T137B Tempest (2006)
T137D Wright (2012)
A T-party is what we call multiple pods of transient orca meeting up! They tend to party for hours to weeks to communicate, socialize, and breed. For these pods, it’s Tasu, Pizza Fin/Rocky II and Loon are the matriarchs that run each pod! The matriarchs are vital to the passage of information, they will teach their calves everything they know; where to hunt at specific times of the year, behaviour techniques, the environment surrounding them, vocalization and hunting tactics. Tasu (T002C) is the mother of Rocky, Lucy and her newest calf Zippy. Tasu was born before our official catalogue systems were created so her code used to be M9. Tasu has had five calves so far, her most recent was born three years ago known as Zippy who is pictured below!
When travelling in larger groups in T-parties we will sometimes see less common behaviours such as porpoising, breaching, and tail slapping! Usually, this is mostly seen during or after they’ve made a kill! It’s a bit more difficult to hunt when a T-Party occurs. However, throughout the trip, we noticed the pods split up and began travelling down the coastline to Porlier Pass. When the pods split up like this it’s to minimize the amount of sound created. Since the mammals they are hunting all have well-established hearing. This allows them to have a chance at ambushing their prey. Whether it be a harbour seal, Steller sea lion or porpoise. This theory was likely accurate as during this split the T034’s successfully hunted a Harbour Seal and then the T002Cs also seemed to have a successful hunt closer to Valdes Island. Afterwards, the celebrations commenced!
Later on in the afternoon, we spent time with Europa (BCX0854), her 2023 calf, Nuage/Beak (BCX1606), and Sherwina (BCY0961)! We saw a lot of low and high fluking dives which allowed us to get some good fluke photos! Did you know that every single humpback we have in British Columbia we can individually identify based on the bottom of their tails and their dorsal fins? The coloration on the underside of their tail is completely unique to each whale! You can clearly see the difference in fluke colouration with each of the humpback whales that we saw today.
We also were able to stop for some other non-whale species during our tour, including Harbour Seals, Steller Sea Lions, and even some Cormorants on the Gabriola Bluffs!
All these unique species and individuals can be seen below in the photos taken by Val Watson and Aly Kohlman.
