March 29th - Orca party off Gabriola
The Salish Sea is a very large area, starting in the north near Quadra Island and extending down through the Georgia Strait, the Puget Sound, and the Juan de Fuca Strait. This huge area is where our whales spend a lot of their time, traveling ad looking for food or socializing with friends and family. We travel throughout the Strait of Georgia during our tours looking for whales and other wildlife. These days we primarily watch the Transient Orcas who normally travel in small groups of 2-6 individuals. Looking for the groups on the water can feel a lot like looking for a needle in a haystack. Thankfully there are 109 pods that travel through our region, this includes lone females and lone males as their own “pod”.
Lately we’ve been seeing a lot of T-parties, often with pods that have welcomed a new little whale to the family in the last few months. These T-parties are usually full of life and always a treat to see. Today we got to spend our time with another T-party - the T037’s, T037A’s, T049C, T036’s and the T137’s were all together traveling south along the East side of Gabriola Island.

These 4 pods plus a lone male, Janet, were cruising along, traveling, and looking for afternoon snacks. Orcas need a lot of food to have the energy to be constantly traveling through our waters. On average an adult Orca will need about 300 lbs of food per day. Orca’s primarily feed on harbour seals that average about 200 lbs as adults, so each adult Orca needs about 1.5 adult harbour seals per day. That’s quite a lot of food. It’s for this reason we think that Transient Orcas usually travel in small groups, with the most common pod size being 4 whales, many pods range from 2-5 individuals. It’s easier for small groups to find the food they need because Seals and Sea Lions are smart, and once Orcas have been through and had a bite to eat, the other prey usually leave the area or haul up out of the water much too high for the Orcas to get.
This group of 18 whales would need approximately 5400 lbs of food, for just one day. That’s about 27 seals. No wonder they travel in smaller groups. Finding 6 seals is a lot easier than finding 27. Although, in larger groups like this Orcas can take on much larger and faster prey, like sea lions, which can weigh over 1000 lbs. That would certainly make a nice snack for this group of whales.
One of the cool things about this T-party is the family relations between the pods. As female Orcas begin having their own calves, they will start to spend more time away from mom, eventually leaving the pod all together with their own calves and becoming their own separate pod. T036 Flapjack is not only mom to T036B Tattertip, but she’s also believed to be the mother of T137 Loon.
Because we only started really studying Orcas in the 70’s we aren’t too sure on the family ties whales would have had before then. Loon and Flapjack were documented leading their own pods separately and it wasn’t until much later that we made the connection and realized that they were likely related. We can’t say 100% for sure because we don’t genetically test our Orcas, but it’s likely that Loon was here to hang out with her mom, sister, and their families.
Likewise, T037 Rocky III is T037A Volker’s mom. This means we had 2 little family reunions going on in the same party today. Mature females will revisit mom often to check in on their families, introduce new family members, or just to get together and hang out. Orcas are incredibly family oriented animals and form lifelong bonds with each other.
