| THE BROTHERS, Yarmouth County, Nova Scotia |
The following is a chronological listing of our 2026 work with terns of the Lobster Bay area in general, but in particular, with the Roseate Terns (ROST) of The Brothers. The report is mostly the work carried out by Alexis Saulnier, Luc Bilodeau and Dr. Shawn Craik. It also includes tern observations from other professionals working on these islands, as well as observations from local residents. - Ted D'Eon
April 26, 2026 - North Brother
This morning six of us left the shore at the end of Rock Road, Lower West Pubnico and headed out to North Brother on a beautiful morning, perfect for the job at hand.
The crew consisted of Shawn Craik with his wife Amélie, Alexis Saulnier, Luc Bilodeau, Geneviève Gauthier and me.
-----------------------
Dr. Shawn Craik is a biology professor at Université Sainte-Anne, Church Point, Nova Scotia.
Alexis Saulnier is a former student of Professor Shawn Craik, now working on her Masters at Acadia University, Wolfville, NS. Her Masters involves tern foraging by species and the food they bring back to the colony, and much more!
Luc Bilodeau is the technician of this "tern colony" team. He runs the boat, does the photography for leg bands, etc.,and the heavy lifting. He is also Alexis' partner in life.
Geneviève Gauthier is a graduate student at Université Sainte-Anne, studing waterfowl.
-----------------------
The plywood blind is still in good shape and the 72 Roseate Tern nesting shelters inside survived the winter well!
The island hasn't changed much since last year other than there is now a little less soil at the southern end. The gang worked hard to remove much of the weeds; these were placed along the shore below the high tide line; hopefully they'll wash away.
And then the numbered nesting boxes were strategically placed so all the numbers could all be seen and read from the blind.
Seven rectangular plots were identified and sprayed with a saline solution to see if this would reduce the unwanted vegetation (especially wild radish) growing among the nesting area; the spray would be repeated two more times. Also, seven "control" plots were identified where no weed managenent would be done, for later comparison with the saline sprayed plots.
It was a lot of work, but with a great team, all went well. Thank you, crew!
Great crew and a job well done! Thank you all.

May 3?, 2026 - First report of terns in the area.
On Friday, May 8, 2026, I had a conversation with a lobster fisherman who had just tied up at the Dennis Point wharf. He told me the first terns he had seen this spring were from the mainland at Pubnico Point "last weekend".
The weather and sea conditions had not been very good for fishing over the past couple of weeks so they had only gone out a few times. This was Friday, May 8, and the previous time they had gone out fishing was on Saturday, May 2. So, from that, I assume that by "last weekend" he must have meant Sunday, May 3.
If and when I get a better date for the first arrival of terns, I'll update this post.

Terns on May 9, 2026
Kathleen MacAulay, Logan Moore and I left Abbott's Harbour at low tide at about 7 am on May 9, and checked North Brother Island for terns. We estimated about 76 Commons and 4 Arctics, but no Roseates. There were 2 Roseates foraging with about 40 Commons at a place called Hoptoad Ledge near Forbes Point. We didn't see any terns around Ball Bar.
We then landed on Bon Portage Island, checked on the alcid colony at Green Island (near Cape Sable Island) and returned to check the Ball Bar area on the way back to Pubnico. The tide was low on our first check in the morning, but by early adternoon, the tide had changed and a strong current had formed at the northern end of Bon Portage and at Ball Bar. A group of about 50 terns were diving at Bon Portage's northern bar including 3 Roseates. From there we looked north and saw an even bigger group at the Ball Bar. An estimated total of 450 terns were foraging or loafing nearby! This is the most terns I've ever seen away from a breeding colony. We counted and estimated from photos that this huge group of terns could have included up to 69 Roseate Terns! At a minimum, there were certainly at least 43 (13 actively foraging + 30 in a single photo of the loafing birds after a flush). We had a similar observation of an early spring large group of terns at Ball Bar on May 12, 2025 (https://ebird.org/checklist/S237001167).
On our way back to Abbott's Harbour, we stopped to look at North Brother again and saw that there were no terns. They must have all been at the Ball Bar!
The attached images (below) are all from Ball Bar on May 9, 2026.

North Brother Terns on May 18, 2026
Kathleen MacAulay, Richard Donaldson and I stopped for a quick look from the boat at North Brother in the morning yesterday (May 18) and saw about 400 terns on the island.

Pubnico Harbour
There have been about 25 terns on Île Ferrée lately. It does look like a pair of Great Black-backed Gulls are nesting there again which isn't great for the terns.
I haven't checked on Île Chespêque.
Thank you, Alix.
May 24, 2026 - Update from North Brother - Email from Alexis Saulnier
Here's a short update from NBI. Luc (Bilodeau) and I went on the island this morning to find approximately 250-275 terns with at least 60 Roseates and 8 Arctics.
I'm glad to say that everything's looking good with the colony: egg laying may have started a bit later than previous years but there are still many Common Tern eggs and a few Roseate eggs, the feeding rate seems good with a typical array of early season prey (small lumpfish, mummichog, hake and herring, some sand lance, and various other fish in small quantities), and no signs of predation.
As usual, we have many returning Roseates that are banded (a full list of bands will be provided later) and we also saw two Common Terns that still have their GPS backpacks (X50 and X57). Unfortunately, the base station hasn't been deployed yet, but we'll let you all know if those tags are still working once we've got everything set up.
We're looking at approximately the 11th of June for the nest count.
We'll keep you posted as the season progresses.
Cheers, Alexis
Thank you, Alexis and Luc
May 31, 2026 - Update from North Brother - Email from Alexis Saulnier
The colony looks healthy and strong, and there are still no signs of predation.
They (the terns) were quite aggressive while we went through the colony and their behaviour is what we expect to see (i.e., not a lot of feeding while partners switch out incubating the egg(s)).
We have 62 Roseate nests, including four active out-of-box nests and a big increase in Arctic Tern nests to at least 15 nests. We also have another returning GPS tagged tern (Roseate Tern band NB4) and we were able to deploy the GPS base station thanks to Jen and Sarah's quick work to get us a functioning one.
Julie (McKnight) will be coming to help us out later this week as we attempt to trap these GPS birds to remove their backpacks.
See a list of identified bands below.

Great to see so many Roseate Tern nests and as well, so many leg bands identified! Great work!

I made my first visit of the year to NBI with Alexis and Luc for some observations and a tour of the island.
The colony was loud and aggressive.
We marked some additional ARTE, COTE and ROST nests in the colony, bringing our total ROST count to 64 nests.
Alexis and I managed to identify some new bands and affiliate couples to specific nests.
New spotted ROST bands : - RX6 (yellow field readable, right leg), with GPS deployed 2025 - NB3 (yellow field readable, right leg), with GPS deployed 2025 - Z26 (red field readable, left leg) - BC1 (red field readable, right leg) - LU1 (red field readable, right leg)

We got to the island for a day of trapping. Prioritizing birds with slipped metal bands causing injuries to their feet and those still wearing GPS deployed in the previous year.
New shelter traps were used to capture the 5 following ROST :
- NH8 (yellow field readable, left leg), formerly B76
- NH9 (yellow field readable, right leg), formerly had a metal federal band (9822-51571)
on its left leg.
Note: This band had slipped and was crushing the bird's foot.
We removed the metal band and added a plastic field readable (NH9) on it's right leg.
To avoid having another injury, no new metal band was placed on it's left leg.
- NJ0 (yellow field readable, left leg), formerly unbanded
- NB3, GPS removal
- RX6, GPS removal

The tern's body conditions after removing the bands and GPS were assessed, and then the birds were released.
The colony seemed strong, and quite a few fish were seen flying overhead during our visit.
New identified ROST band: BE1 (red field readable, right leg)

June 5, 2026 - Visit to Gull Island - from a text received from Alix d'Entremont.
About 90 or more terns there; no Roseates.
Two sheep are also there; the shepherd told him they would soon be removed so they wouldn't trample the tern nests.
Thank you, Alix.
June 7, 2026 - Pubnico Harbour - from Alix d'Entremont's Facebook page.
Kathleen MacAulay and I launched the Zodiac in Pubnico Harbour this afternoon at high tide. Our goal was to check on the tern colonies at Île Ferrée and Île Chespêque.
We estimated 70 on Île Ferrée and 27 on Île Chespêque. Like previous years, Île Ferrée also had a Great Black-backed Gull pair that nested and we saw two young on the island today.
There was still a small group of scoters in Pubnico Harbour that included 9 Surfs and one White-winged.
Thank you, Alix and Kathleen.

Census day!
Despite some empty scrapes (presumed egg predation) being seen for all three species as we made our way around the island, we were pleasantly surprised by the total number of nests on North Brother Island this year.
COTE : 577 nests ARTE : 15 nests COTE/ARTE : 1 nest ROST : 62 nests - TOTAL : 655 nests (579 in 2025)
In addition to eggs, our first 2 COTE chicks for the year were hatched. 3 Common Eider ducklings were also found hanging out in a ROST box near their nest.
Though the colony was aggressive and loud during our visit, a few terns managed to land on our heads, which was quite a welcome surprise!
With the weather looking uncooperative for the rest of the week, the terns will get a well-deserved break from us until our next visit early next week.
