Three generations of Humpback Whales have now been documented!
This is such an indication of the great collaborative effort in studying the fortunate return of Humpback Whales off British Columbia’s coast, and its importance.
Alethea Leddy was the first to document Apollo with a calf, now nicknamed Nova. Alethea’s photos from June 18th near Race Rocks even allowed us to determine that the calf is male. The calf had been lying on his back tail-lobbing whereby the pelvic area could be seen. See Aletha’s photo at the end of this blog that allowed determination of Nova’s gender. For detail on gender determination in Humpbacks, click here for our blog on the subject.
We know that Apollo was born in 2010 to Horizon but did not know her gender before now.
We first documented Horizon in 2004 when she was already at least subadult. Apollo is her first known calf. We documented a second calf in 2013 and have not had re-sightings of this whale.
Calves only stay with their mothers for a year. Having these solid ID photos allows us to ID them in future. Because the calves often lose a lot of the white pigmentation in their tails as they age, It is particularly helpful to also have photos showing both sides of the dorsal fin and the trailing edge of the tail. Being able to study whales as individuals allows us to have data informing everything from age of first calving (varies per population), to life expectancy, to social associations, to how the whales use the coast.
Humpbacks are nicknamed for distinctive features so that it is easier to recognize them as individuals. Horizon has horizontal lines on her tail. The markings on Apollo’s tail suggest planets. And, while some of the white will likely disappear on the calf’s tail, there is a distinctive line and a moon-shaped bump that will likely stay. Thereby, Alethea suggested Nova, also keeping with the celestial theme of these 3 generations of whales.
To make the point again that it takes a dedicated community to study giants, below are the names of all those who have contributed sightings of these 3 whales (outside of our direct MERS team). This includes naturalists, captains and guest of at least 9 ecotourism companies as well as our research colleagues:

Marine Education and Research Society
Summer Student Position: Data Analyst
The Marine Education and Research Society (MERS) is a non-profit organization dedicated to promoting conservation and understanding of marine ecosystems through scientific research, environmental education, and marine wildlife response. We are based on NE Vancouver Island. For information about MERS’ research, education and wildlife response efforts, see www.mersociety.org.
The Data Analyst will be involved in MERS’ efforts to study and protect marine mammals in British Columbia, with a focus on consolidating Humpback Whale sighting and photo-identification data as part of a province-wide project to better understand this population. This Humpback Whale study is a collaborative, coast-wide effort that will allow for enhanced knowledge of the abundance, habitat use, social associations, movements, and threats of Humpbacks in B.C., for the purposes of conservation.
Duties will include:
- Conducting comparative analysis of Humpback Whale catalogues to determine the identifications of individual whales.
- Data entry and database management for Humpback Whale sighting and photographic data.
- Assisting in supervising volunteers during data entry and photographic data analysis in order to maintain the quality of the MERS databases.
- Aiding in MERS’ work to serve as a resource to media and the local community (with a focus on local ecotourism operators) in order to enhance the economics/value of wildlife viewing experiences.
- Helping to develop resources to reduce threats to whales and, thereby, increase the sustainability of ecotourism in the region.
- Other office-based work as needed.This is an office-based position but there may also be some opportunities for the Data Analyst to accompany MERS researchers on boat-based surveys to collect Humpback Whale photo-identification data.
- Are Canadian or have a Canadian work permit. (Please note: MERS will not be able to assist candidates in obtaining a Canadian work permit).
- Are students currently enrolled in a full-time post-secondary program, returning to school in the fall of 2018 (funding requirement).

“How to Save a Whale” is an essential resource on the risks of collision and entanglement. It was made possible by the Sitka Foundation. Please see below for the video and share widely.
With the fortunate increase in the number of Humpback Whales off our coast, it is essential that boaters know more about the risks of collision and entanglement (for the sake of whale AND boater safety).
Our preliminary results, conducted in collaboration with Fisheries and Oceans Canada (DFO), show that over 47% of Humpbacks in British Columbia have scarring that shows they have been entangled (>1,000 Humpbacks). This data provides an indication of how very serious the risk of entanglement is. It does not reveal how many Humpbacks have died as a result of entanglement.
For Canada’s Marine Mammal Regulations and key points on how to avoid collision, please see our page www.SeeABlowGoSlow.org.
Summary of key points on what to do in case you find an entangled whale:
- With great urgency, report the entanglement with location. In British Columbia call the DFO Incident Line at 1-800-465-4336. If you do not have cell service, use VHF Channel 16 (Coast Guard).
- If at all possible, remain with the whale at a distance until trained help arrives or another boat takes over tracking, otherwise the chances of relocating the whale are greatly diminished
- Take whatever video/photos are possible but maintain a distance that doesn’t stress the whale.
Why it is so important NOT to attempt to remove any fishing gear or rope from the whale:
- It risks human and whale safety (has led to human death). Professional training and equipment are needed to assess the entanglement and proceed safely with the greatest chance of success.
- Often, much of the fishing gear in which the whale is entangled is not visible at the surface. If members of the public put themselves at risk and remove gear at the surface, they would not help the whale because now it is more difficult to:
– Recognize that the whale is entangled; and
– Disentangle the whale even if it is relocated.
Trailing gear at the surface provides the opportunity for trained responders to attach a tag to track the whale and/or to attach floatation to maintain contact with and slow down an entangled whale. Loss of this gear can significantly reduce rescuers’ ability to save the whale.
There are two opportunities to have the adventure of a lifetime and contribute to our work at the Marine Education and Research Society. We are so grateful to Stubbs Island Whale Watching and Ocean EcoAdventures for making these opportunities possible (September 30 from Cowichan Bay and October 7th from Telegraph Cove). We’ve tried to give a sense of the wildlife in the fall with the slideshow below. All photos were taken in October.
These are very significant fund-raisers for what we do to reduce risks to whales. They are an opportunity for us as researchers to share our work directly with you and for you to see and learn from the astounding beauty of this coast.

This is very inspirational. So often, you don’t get to know if your efforts have an impact but this time . . .
Ashley Hasgawa is a student at Shawinigan Lake School. She attended one of our “Humpback Comeback” presentations. We always make quick mention of our work around endangered Leatherback Turtles – that they belong off the coast of British Columbia, coming all the way from Indonesia and that a risk to them is that they cannot discern plastics and balloons from their jellyfish prey. (See leatherbacksinbc.org.)
Ashley later took up contact asking for data around this risk to wildlife, explaining that her school had a balloon-release at their Closing Day ceremony. She had done the work to know that, while they use biodegradable balloons, these can take a very long time to breakdown (over 6 years, see this link).
She wanted to ensure she had solid facts before having a discussion at her school about how the risk could be further reduced.
We provided the data and some links to alternatives for such ceremonies. The lowest risk would be not to release balloons.
Never could we have anticipated the ingenuity of the compromise agreed upon by the graduating class and school management.
Here is Ashley’s recent email describing what they did:
” . . . We attached a carabiner to each balloon, as a grad class, we all clipped the balloons onto a fishing line like a kite. As you can see in the pictures [see below], they all flew out together. Later on, we brought it back down again after the graduation ceremony. Unfortunately, there were still about 3-4 balloons failed on clipping onto the fishing line, but most of the balloons did get brought down, got popped by our school and dumped to our own compost facility. This could not have happened without the support of our headmaster, David Robertson, and the teachers, especially, my fine art instructor, Scott Noble for always helping me. Thank you so much for your fantastic presentation, I will never forget it. I am so happy that I went and made a difference for the environment.”
Imagine how happy we are.
Thank you Ashley and all those who made it possible for a student’s concern to lead to empowerment. Our great hope is that this approach to balloon releases will go widely into the world, creating further awareness of the risk to wildlife.

One of the best things about researching individual whales is that, no matter how long we study them, we keep being reminded of how much more there is to learn…
In 2011, MERS researchers observed a humpback whale named “Conger” (BCY0728), a whale that we have documented off northeastern Vancouver Island since 2009, doing something that we had never seen a humpback do before. Conger was remaining at the water’s surface with his mouth wide open, and he stayed like this for an extended period of time.
With his mouth open, he spun slowly in place for about a minute, and then used his flippers to push fish toward his mouth!
After observing this feeding behaviour several more times, we named it “trap-feeding”, because it reminded us of the way that Venus flytraps catch flies. Humpbacks were remaining stationary and waiting for prey to enter their mouths. By studying the behaviour further, we have learned that, in addition to often using their long flippers to direct fish toward their mouths, humpbacks also benefit from diving birds that are chasing the same prey. While trying to escape the birds, the small fish appear to school in or next to the whales’ mouths.
We know of only two whales who used this trap-feeding behaviour in 2011 – Conger and “Moonstar” (BCY0768), who was three years old at the time. But by the end of 2015, sixteen of the humpback whales that feed off northeastern Vancouver Island had been documented using this strategy at least once. In some cases, humpbacks even trap-fed side-by-side!
Aided by the many people that have contributed photos, videos, and sightings of trap-feeding over the past six years, MERS researchers have concluded that when whales trap-feed, they are feeding in the same locations and on the same prey species (juvenile herring) as when they lunge-feed. BUT there is a big difference in the size and density of the schools of fish that humpbacks consume when they trap-feed vs. when they lunge-feed…
The schools of herring that humpback whales trap-feed on are much smaller and less dense than the schools that they lunge-feed on. We believe that trap-feeding is an energetically efficient way to feed on these smaller schools of fish. When whales are lunge-feeding, they accelerate toward their prey, then open their mouths – an energy-intensive strategy that only makes sense if schools of fish are large and dense enough to result in a net energy gain for whales. But while trap-feeding, whales open their mouths while stationary or near-stationary, and therefore use much less energy.
If you see humpback whales exhibiting this feeding behaviour, we would love to know! Sightings and photos can be sent to firstname.lastname@example.org
Additionally, MERS researchers are in the process of publishing a study focused on trap-feeding – so a lot more information about this new humpback whale feeding strategy will be available soon!
