Plentiful Humpbacks!
Of the 126 sightings we received this week, 99 of them were of Humpback whales. There are many more Humpback whales out there around British Columbia and it is an amazing conservation story to see their population rebounding to healthy levels from where it was over 40 years ago.
A number of Humpback whales were observed breaching. The cover image shows a Humpback whale just about to re-enter the water after breaching with its underside (ventral side) facing up, and you can see the pleats on its underside. These pleats or creases allows the underside to expand significantly when the whale is foraging so the whale can take in a large amount of water with prey into its mouth. Blue whales and Fin whales are from the same family as Humpback whales and they also have pleats on its lower jaw. Also observed were a number of Humpback mother and calf pairs; calves usually stay with their mothers up to one year before they seperate from them.
Transient Orca were observed a lot less than usual. On June 26th, a larger pod of about 20 Transient Orca was observed in Discovery Passage. One pod of Transient Orca swam into Departure Bay in Nanaimo on June 27, stayed for a short time, and departed; they were observable from land. The T046B pod was observed a few times which includes a younger Orca that is white in colour (ID #T046B1B). This pod was seen near Powell River on the evening of July 1st and a couple of days later on July 3rd, they were seen in Howe Sound near Langdale. Then on July 5th, the T046B’s were near Mitlenatch Island – go down to our Magazine Section and read about an amazing encounter with them! They really travel around quite a bit!
Rounding our report are sightings of Pacific White-Sided dolphins and Dall’s porpoise. Dall’s porpoises appeared in Sechelt Inlet and at the north end of Loughborough Inlet, which are rare occurrences.
Boaters, please use caution on the water. Remember N.E.W.S. when you see a whale, meaning put your boat in NEUTRAL, ENJOY the view, WAIT till the whales are at a fair distance, and then SLOWLY leave the scene.
The Federal Government (DFO) has issued the following statement about watching whales in the wild: “To address disturbance in the presence of whales, a mandatory 400-metre vessel approach distance for all killer whales is in effect starting June 1, 2020 in all southern British Columbia coastal waters between Campbell River and just north of Ucluelet. The Marine Mammal Regulations continue to remain in effect year-round, including maintaining a minimum 200 metre approach distance from all killer whales in Canadian Pacific waters other than described above, and 100 metres for other whales, porpoises and dolphins OR 200 metres when the animal is in resting position or with a calf.”
WOWs works throught the year, so please continue to keep your eyes open, and report your sightings to us.
