#20 Bay of Warmth (Part 5): GSL Right Whales!

This is Part Five of a series of posts about surveys taking place in the Baie de Chaleur in the southern Gulf of St. Lawrence. Click on the links to read Part One, Part TwoPart Three and Part Four!

After a beautiful afternoon with near ideal survey conditions we began our long trek from Bonaventure Island back to the Stonehaven dock. We encountered the (presumably) same fin whales again in the same area and continued our return in relatively quiet conditions. That is, until about 5:30 PM. We were traveling along the Quebec side of the bay and spotted a blow off the bow followed by a fluking dive. It was what we all had been waiting for: a North Atlantic right whale! This being the GSL team’s first sighting and all the excitement aboard the R/V Callisto was palpable. We quickly went into action exchanging our binoculars for cameras, recording time and coordinates, and keeping watch for it to reappear. We did not have to wait long for it to resurface and the rest of the sighting consisted of it curiously approaching our boat and diving at short intervals. We discussed the familiarity of its scars and callosity and concluded quickly that we recognized this individual: Catalog #1278.

First seen in the Great South Channel in 1980, this adult male has an extensive sightings history in every known habitat over the last 35 years. One of the most interesting realization we had was that he was photographed about 4 miles from this site close to a year before, and had been seen a few times prior in the Gulf of St Lawrence. With no dedicated right whale effort in the Bay of Chaleur it is possible that this and other whales visit this area more frequently than documented and that this habitat could be more used than we thought.

We had one more survey day the following Thursday before returning to Lubec, and had our second whale of the trip encountered another old male very close to our first sighting (~6 miles), identified as Catalog #1307.

This individual was first seen in 1974, and also has been observed in every known habitat over its 40 year sightings history. He actively avoided our boat, which may shed some light as to why he bears far fewer scars than #1278.

Unfortunately high winds on Friday and Saturday prevented us from another survey prior to leaving. Given that both whales we observed were swimming into the Bay of Chaleur it is quite possible that more whales arrived after we departed. Hopefully with more effort and data collection we can figure out the significance and usage of this bay to North Atlantic right whales.

#19 Bay of Warmth (Part 4): Gannets Everywhere

This is Part Four of a series of posts about surveys taking place in the Baie de Chaleur in the southern Gulf of St. Lawrence. Click on the links to read Part One, Part Two, and Part Three!


While hauling the R/V Callisto, Alex noticed an adult northern gannet with limited movement at the boat ramp. Upon approach he saw that there was a hook stuck in its wing with line originating from its mouth; the line wrapped the wing in such a way that it could not extend it and who knows how long it had been entangled like this. We knew that we had to do something to help this individual.

We promptly devised a plan to safely secure the bird and gathered the appropriate tools (gloves, wire cutters, towel and sunglasses as safety goggles) to remove the hook and monofilament line. Alex blocked its access to the harbor and distracted it so Monica and I could carefully capture it.

We successfully cut the hook and removed as much line as we could, and were happy to see the gannet flee to the water with its wings lifted.

On Tuesday, August 25th, we had a great forecast so decided to travel to the northern opening of the Bay of Chaleur in an attempt to make it as close to the Gaspé Peninsula as time and weather would allow. We encountered some fin and minke whales, but other than that the survey was relatively quiet. We reached Percé in the afternoon and stopped for a quick lunch break and to take in the beautiful views.

Here we got to watch northern gannets on Bonaventure Island, the largest colony in North America.
Males are competitive for prime nesting sites and are the principal nest builders using mud, grass, seaweed, and feathers. Northern gannets are monogamous and long term pairs often use the same nest for years and potentially mate for life. Both parents incubate the single egg and are active in feeding the chick.

It was amazing to see the white bodies crowding the cliffside and the active scene on the island and in the air. As we watched the gannets on and around Bonaventure we pondered (and hoped) that the one we had helped earlier in the trip was there and reunited with its mate. After this refreshing break we continued our tracklines back towards our dock and scanned the water for what we had come to find- a right whale.

#18 Bay of Warmth (Part 3): Heading Offshore for Right Whales

This is Part Three of a series of posts about surveys taking place in the Baie de Chaleur in the southern Gulf of St. Lawrence. Click on the links to read Part One and Part Two!

With three full days of survey in excellent conditions and no right whales to be seen we were rejuvenated by a report from our colleagues in the air.  An aerial survey had found a group of approximately 15 right whales about 40 miles offshore of Miscou Island, New Brunswick.  Miscou marks the separation of Baie des Chaleur with the Gulf of St. Lawrence. In order to travel to the reported location in the R/V Callisto we needed a day of preparation.  The sighting was far from our wharf (about 80 miles) and we quickly realized that moving the Callisto and launching from Lameque Island  (via Miscou Harbor) made more sense. However, the drive would take over two hours on dark, secondary roads well before sunrise if we wanted to be on the water at first light.  We had been warned many times from the locals about the real threat of moose on the road and car accidents. We took advantage of a windy day on land and packed our food cooler, equipment and the boat and drove to Caraquet (about halfway between Janeville and Miscou Harbor).

In Caraquet we rented a life raft  and booked a hotel room for the night.  Our morning offshore would begin very early as we planned on leaving the hotel around 5:00 am to continue our drive to Miscou Harbor.

 The weather proved amazing for our trip offshore and spirits were high that we would be able to find the small aggregation that had been sighted just three days prior by the aerial survey.  However, after a full day of survey we only logged fin whales, minkes and a few sightings of tuna.  Feeling disappointed at what we thought was a sure thing we headed back to shore discouraged but thankful for the gorgeous weather and sighting conditions.
