    The Brothers are two tiny islands about 1 km west of Lower West Pubnico, Nova Scotia, Canada.
    They are owned by the province and were designated a wildlife management area in April 2007.
    Access to them during nesting season (April 1 to Aug. 31) is by permit only.


    This report will mostly cover work being done on North Brother, mostly from my perspective.

    Our work on these islands is done in cooperation with Canadian Wildlife Service (CWS) and the Nova Scotia Department of Lands and Forestry (NSDLF). - Ted D'Eon

    OBSERVATIONS:

    The following is a chronological listing of our 2022 work with terns of the Lobster Bay area in general, but in particular, with the Roseate Terns (ROST) of The Brothers. The report also includes tern observations from other professionals and university students working on these islands, as well as observations from local residents. - Ted D'Eon

    February 13, 2022 - The Brothers (North and South).

    I've recently purchased one of those 249 gram drones (DJI Mini 2) and flew to The Brothers from the end of Pond Road, Lower West Pubnico. All went well, and I got the photos and video I wanted. I was impressed!

    My primary goal was to verify the condition of the blind on N Brother as it looked fine and intact from the mainland.

    I also wanted overhead shots of the islands like I used to get with my paramotor (I haven't used it in a couple of years). I believe it's always useful to get reference photos of these islands to compare the changes over the years.

    The plywood blind looks the same as it did on the last day I was there (Sept 27, 2021), so I'm quite confident it will survive the remaining winter.

    See the photos below.

    I have modified 10 old-style square ROST shelters to add to the 50 we already have on North Brother. I bekieve these should work fine.

    What we (Gavin Maclean, Alexis Saulnier, Luc Bilodeau, and Shawn Craik) did today.

    Weather forecast was giving wind but calming down somewhat in the afternoon.

    Well, it was still blowing when we left Abbott's Harbour at 1pm.

    No problem getting to the island as it is not very far, but the landing was a different story

    Alexis and I made the first attempt with 6 ROST shelters and a few more items. We partially swamped the Zodiac upon making land and sort of lost control of it momentarily. We each got wet up to our thighs.

    I decided it was too dangerous to get everyone on the island, so we would get back to my boat after securing the ROST shelters we brought to the island into the plywood blind.

    We made it back to the boat and discussed the situation with the group.

    After some discussion, we decided to make another try and this time land at a part of the beach which didn't seem to be as wild as our first attempt.

    This time we got everyone safely on North Brother; all of us got wet to some extent.

    See the photos below of our work on the island. We managed to get done what we set out to do, and now, 60 ROST nesting shelters are properly placed on the island, ready for the terns' arrival in a week or 10 days.

    When it came time to leave the island, the weather had improved a lot, and now with very little swell so we had no problem getting back to Abbott's Harbour.

    Thank you so much to the wonderful crew: Gavin Maclean, Alexis Saulnier, Luc Bilodeau, and Shawn Craik.

    We had a very successful day!

    April 26, 2022 - Lobster fisherman, Lorne Spinney photographed a tern on a buoy somewhere in Lobster Bay.

    May 2, 2022 - "About 50 terns about 1.75 mile west of John's Island", reported by lobster Fisherman, Edouard D'Eon. That's about 10 kilometres south of The Brothers.

    May 3, 2022 - Alix d'Entremont writes:

    Jerome d'Eon and I swung by North Brother this morning before surveying for Brant on 26 Lobster Bay Islands (91 km round trip). At least 160 terns were present on North Brother, including about 10 Arctics. See the checklist:

    I've uploaded photos of the colonies on eBird: (see https://ebird.org/checklist/S108828493)

    Thank you, Alix.

    May 12, 2022 - North Brother visit by Shawn Craik, Sophie Landry, Luc Bilodeau & Alexis Saulnier - Sophie Landry writes:

    ... Upon our arrival, we saw but four terns circling North Brother. Throughout our visit, we observed a few small flocks of terns, including one Roseate, and the largest flock counting a total of 20 terns. We also noticed one Common Eider nest with 4 eggs on the island.

    We accomplished what we had set out to do for this trip, which was to check the Roseate nesting boxes for the beginning of nest scrapes, as well as clear any encroaching vegetation in or around the boxes.

    "Kathleen MacAulay and I viewed North Brother briefly from the boat yesterday (May 14) in the fog. We estimated about 35 Common Terns and 3 Arctics."

    Thanks, Alix and Kathleen.

    May 19, 2022 - Lobster fisherman. Ben Morton, asked other fishers in Lobster Bay to report to him observations of terns around Lobster Bay Islands:

    Text sent from him to Shawn Craik

    "...guys fishing around (Gull Island) are seeing them."

    May 20, 2022 - North Brother visit - Sophie Landry writes:

    "As we approached the island this morning, we estimated between 150-200 terns.

    Our goal today was to identify some COTE and ARTE nests and check ROST nest boxes. We counted 7 ROST boxes with nest scrapes (no eggs yet) and about 30 COTE nests (to be confirmed from the blind).

    We also counted 7 eider nests (one of which remained occupied by the female during the entirety of our visit!).

    We did not identify any ARTE nests, but we didnít walk along the eastern ridge as to not disturb the eider on her nest.

    Team: Shawn Craik, Alexis Saulnier, Luc Bilodeau & Sophie Landry."

    Thank you, team Université Sainte Anne, and to Sophie for the report. Nice to see the 150 to 200 terns at North Brother; this is very encouraging for another successful season for 2022!

    May 23, 2022 - Alix d'Entremont texted me, "About 25 terns on Île Ferrée (Pubnico Harbour). 40 feeding between Île Ferrée and the Pont du Marais." Good news!

    May 24, 2022 - Dennis Point and North Brother - Trip report by Alexis Saulnier.

    Sophie and I started out our day by visiting Dennis Point Wharf to conduct observations of fish (i.e., herring) and terns in the area, where we established that neither were present at the time we were there.

    Around noon, Luc joined us for a visit to North Brother Island, where we estimated about 350 terns upon our arrival. We walked through the colony to check the ROST shelters, as well as mark Common (22) and Arctic (10) tern nests for monitoring.

    Seven shelters contained single Roseate tern eggs. Only six Roseate terns were seen at a time during the observations from the blind, however the state of the ROST shelters indicate that at least 14 Roseate terns have been frequenting the island.

    Two banded Roseate terns were identified: L12 (red band on the right leg Ė nest R41) and L93 (red band on the right leg Ė nest R43). Team: Alexis Saulnier, Luc Bilodeau & Sophie Landry

    May 25, 2022 - Trip report to Wood's Harbour islands by Sophie Landry.

    Shawn, Alix and I made a trip from Woods Harbour to survey foraging terns in the area.

    "The Ball" island, bar and ledge - near Wood's Harbour (Navionics chart)

    At The Ball bar, the tide was

    high, but we saw up to 10 COTE and 2 ROST foraging over the rip as near as 50m from the boat. Prey seemed to be mostly sandlance (see below, photos by Alix). We also saw a few COTE foraging at the bar near Johnís Island and 2 ROST fly over the bar at Johnís Island going South.

    May 26, 2022 - North Brother - Trip report by Sophie Landry.

    On Thursday, (May 26) we installed the weather station on the island and checked the status of nests of all species. About 450 terns were circling the island as we arrived. There were 17 ROST nest boxes with eggs (two of which had 2 eggs)! We identified more ARTE (24 total) and COTE (25 total) nests and 2 new COEI nests (9 total). Two more banded ROST were identified at nest box 2: L03 and L05.

    We also started our directional prey scans, during which we saw most prey coming from the South.

    Team: Shawn Craik, Alexis Saulnier, Luc Bilodeau & Sophie Landry.

    See below, some photos (taken by Luc Bilodeau) of prey seen on the island on May 26.

    May 30, 2022 - North Brother report by Soplie Landry.

    We headed out to the island in the afternoon to check the status of nests of all species and collect directional prey data.

    Our estimate tern count is about 500 terns. We counted 35 ROST nests (2 outside nest boxes)!

    In terms of prey species, we saw sandlance, lumpfish, hake, and herring.

    Five banded Roseate terns were identified:

    - L76 (red band on the right leg Ė nest R39),
    - L35 (red band on the left leg Ė nest R42),
    - L96 (red band on the left leg Ė nest R57),
    - L47 (red band on the right leg Ė nest R29), and
    - L00 (red band on the left leg Ė nest R29).

    June 1, 2022 - Dennis Point Wharf - Trip report by Alexis Saulnier.

    Wednesday morning, Sophie and I went to Dennis Point Wharf to check for the presence of fish and terns.

    During our observations to the North of the wharf, we noted the presence of a large school of fish Ė easily a few hundred Ė which we identified as possible herring. This marks our first observations of probable prey for the terns at Dennis Point this year!

    We also noticed a dozen larger orange coloured fish measuring about a foot in length, but the visibility was too poor to identify them.

    Three Common terns were seen diving about 50 m off the new extension to the wharf, one of which even circled a nearby effluent pipe surrounded by gulls.

    (Later in the day) We were unable to make our way to North Brother safely due to large swells, so we returned to Dennis Point for more observations with Shawn.

    June 3, 2022 - At sea, south of The Brothers, towards Wood's Harbour - report by Sophie Landry.

    During our at-sea foraging survey, we didnít see any terns at The Ball bar. However, we saw a total of 18 terns, including a total of 5 ROST, flying over Johnís Island toward the south. A group of 4 COTE were diving around the bar at Johnís Island before continuing south.

    Later, on North Brother Island, we didnít see many terns returning with prey, but we did see 1 ROST returning with sandlance from the South.

    Team: Shawn Craik, Alix díEntremont & Sophie Landry.

    June 3, 2022 - North Brother - Trip report by Alexis Saulnier.

    Luc and I visited Dennis Point to conduct observations, however no fish nor terns were present while we were there.

    We then joined Shawn and Sophie for an outing to North Brother Island where we visited the nests and observed terns arriving to the island with prey. About 500 terns flushed the island upon our arrival.

    We found 41 active nests of Roseate terns, 28 of which had two eggs. One nest had but a single unfertilized egg (see photo).

    No evidence of predation or carcasses was found, indicating a healthy colony. All nine Common Eider nests were active and warm.

    We also observed a tern with a yellow band but were unable to clearly see the ID number.

    Thanks to Lucís photos, we were able to identify more banded Roseate terns:

    - LJ0 (red band on the right leg)
    - B65 (red band on the left leg)
    - LD0 (red band on the right leg)
    - B75 (red band on the left leg)
    - L32 (red band on the right leg)
    - L33 (red band on the left leg)
    - L40 (red band on the left leg)
    - B95 (red band on the right leg)

    June 6, 2022 - North Brother - Trip report by Sophie Landry.

    We made our way to North Brother Island in the morning to collect some directional prey data. Upon arrival we estimated upwards of 500 terns. During our observations, most terns with prey were seen returning from the South.

    The most common prey species brought back to the colony was first and foremost herring, then some sandlance, butterfish, hake, and lumpfish.

    We were not able to return in the afternoon due to the wind.

    Note: We also saw a COTE with an interesting tag (see photo).

    This must be the same bird we saw on North Brother on May 31, 2020. Or, is it? In 2020, it seemed to be missing the claws and possibly a toe from its left foot!?

    This is what I wrote at that time (2020).

    "There was also a banded COTE with an orange flag on one leg and a metal band on the other. The grey metal band looks Argentinian. We've seen Argentinian bands on North Brother before. See below."

    June 7, 2022 - Trip to Ball Bar with Alix d'Entremont - report by Sophie Landry.

    On Thursday morning (June 7) , Alix and I made another trip out to The Ball bar and surrounding islands to monitor tern feeding behaviour in the area. There were no terns feeding at the Ball, but we saw a total of 9 COTE fly over the bar to and from the South, including one individual carrying a fish. The occasional tern would bank over the bar or attempt a dive, but no groups were seen foraging consistently.

    At Johnís Island, we saw similar behaviour, terns were flying over the bar to and from the South. One tern dove once before moving on. We didnít see any ROST on our trip.

    June 7, 2022 - Dennis Point and North Brother - Trip report by Alexis Saulnier.

    Luc and I started by visiting Dennis Point Wharf in the morning. Although we saw no fish near the wharves, we did see three Common terns dipping over the water to the South of the new wharf extension (roughly the same location as was last recorded on June 1st).

    With great weather, we sailed to North Brother mid-morning. As we arrived, we estimated that no less than 550 terns were circling the island.

    We walked through the colony to check the status of the nests and found 43 Roseate tern nests. The colony was more aggressive than usual and, though we observed some terns arriving with fish, there was a relatively low volume of prey brought back to the island. We believe this may be due to their anticipation of the hatching of chicks in the coming days.

    Lucís photos revealed that hake and herring were the prey of choice for the day. We were also able to identify a new banded Roseate tern: L53 (red band on the right leg).

    All nine Common Eider nests were still warm and active Ė one even had a two newly hatched ducklings! There was no evidence to suggest that predators nor the Avian Influenza have reached the colony.

    June 11, 2022 David Surette, a retired lobster fisherman and seaweed harvester living in Middle West Pubnico, very close to the shore of Pubnico Harbour, reports no terns foraging this year below his house. I checked the situation out also, and also couldn't scope out a single tern along that shore and as far as I could see.

    I scoped out Île Ferrée and couldn't see any terns there either!

    The island is about 30 metres in diameter at its widest and in 2020 hosted an incredible 277 Common Tern nests in 2020, 176 nests in 2019, and 41 in 2018.

    However, 2021 was not a good year for Île Ferrée: 24 tern nests there on May 26, down to 3 on June 2, and then up again to 25 on June 6. 2021. Definitely a predator problem there! (Great Horned Owl, gull, mink, fox?)

    June 11, 2022 - (evening) My daughter, Ingrid D'Eon, reported about 4 terns foraging at Abbott's Harbour.

    June 11, 2022 - Alix d'Entremont reports "At least 2 Roseates on nests at Cape Sable!". Wow, exciting news! Thanks Alix!

    Alix writes:

    Kathleen MacAulay and I spent about 1.75 hrs anchored off the large tern colony on Cape Sable this morning (red star in map below).

    We were able to confirm at least five Roseates sitting on nests. We did not land so only observed from the boat. I was able to take images of the fish being carried by the ROST. We were not able to determine which direction the ROST were returning from with fish as we focused on confirming breeding.

    We did, however, see a ROST foraging at Hawk Inlet (here 43.404024, -65.614290) with a loose group of COTE/ARTE and then another ROST foraging with a group of about 30 COTE and 20 ARTE (here 43.405252, -65.627648). See the orange stars in the map below for these two Roseate foraging locations.

    There were COTE and ARTE foraging between the two green stars on the map below. Roughly 20-50 COTE/ARTE were seen headed west from the direction of Barrington Bay (see green arrow in map below). There were terns seen foraging sparsely farther out in the bay, but I believe most terns headed west were from an area farther east than we could see (towards Baccaro?).

    June 12, 2022 - North Brother and Dennis Point - Trip report by Alexis Saulnier.

    After many days of large swells, high winds, and rain, we were finally able to make our way to check on the colony on North Brother.

    Upon our arrival, we noted the very first Common tern chicks. We then decided we should return to shore and prepare for the nest count.

    Luc and I walked through the colony marking and calling out nest species and egg counts as Sophie took note of our findings.

    Our final tally of the nests on North Brother Island for 2022 is a remarkable 1032 nests Ė the NBI nest count for 2021 was 893.

    To date, we have identified 43 Roseate tern nests. We noticed about a half dozen broken tern eggs, however it was difficult to tell whether they had been depredated or sent rolling down the rocky shore by waves and/or wind following an attempt at predation.

    We were unable to check the status of all the Eider nests, but seven were still active and warm, some with eggshells and egg membranes nearby indicating a hatched duckling. One additional Eider nest was found with two eggs. One Common Eider egg was found that had clearly been depredated.

    We finished off the day by visiting Dennis Point, but no fish were seen surrounding the wharf.

    12 Common terns were seen flying over the water to the East of wharves 1 & 2 (a few aborted dives, but no evidence of foraging was observed).

    14 Common terns were seen to the South, but it is possible that some of these had been previously counted to the East of the wharves, as they had been last seen heading to the South.

    Team: Luc Bilodeau, Sophie Landry & Alexis Saulnier

    Well done Luc, Sophie, and Alexis.

    1032 is a huge number of tern nests for this tiny island!
    It is the highest number of tern nests that I know of or ever heard of being recorded there! Amazing!

    June 15, 2022 - Dennis Point and North Brother - Trip report by Sophie Landry.

    In the morning we headed to Dennis Point, where we saw a few terns fly overhead. The only foraging tern we saw was picking at the scraps left behind by the gulls at the effluent pipe South of wharf 4.

    The construction supervisor at the wharf, Bob Morton, informed us that on Tuesday (June 14) he saw quite a few terns diving about 10 feet from the new wharf extension and he saw schools of fish near the edge of the wharf. We also saw some prey fish, possibly juvenile herring, in between wharves 2 and 3.

    In the afternoon, we were able to get out to the island (North Brother) to check the nests and collect directional data. Most terns returning with prey were seen from the East and the North.

    We also saw our first ROST chick, so we will be banding soon!

    June 16, 2022 - At-sea survey - Trip report by Sophie Landry.

    Shawn, Alix and I completed another at-sea survey on Thursday morning. We saw 3 ROST and up to 3 COTE foraging East of The Ball bar.

    Near the bar at Johnís Island, we saw 1 ROST dive once South of the bar, but no other foraging activity. However, we were able to see small fish from the side of the boat (about 0.75 culmen in length).

    A total of 10 COTE were seen flying over the surveyed area toward the South.

    June 16, 2022 - At-sea survey - Trip report by Alexis Saulnier.

    While Sophie and Shawn were doing an at-sea survey with Alix, Luc and I began the day by visiting Dennis Point Wharf to observe the presence of fish and terns. What we suspect to be juvenile herring was spotted at two of the observation sites next to wharves 1 and 2. We also observed six Common terns dipping for bits of fish left behind by the gulls feeding at the effluent pipe, as well as up to eight Common terns foraging and dipping on the northern side of wharf 1.

    Four Common terns were foraging between the boats stationed at wharves 1 and 2. To the south of wharf 4, we counted 17 Common terns where the majority of which (9) were diving adjacent to the new extension to the wharf. Up to eight Common terns were looking for leftover pieces of fish near the effluent pipe with a few gulls.

    On the island, Shawn, Sophie, Luc, and I thinned the vegetation around the Roseate nesting boxes to limit growth and facilitate observations from the blind.

    We then conducted observations looking for terns arriving to North Brother with prey as well as a feeding watch on the nest (R44) with the only hatched Roseate tern chick. Most prey was seen arriving from the East and South, comprised of herring and mummichog. Our observations in the afternoon revealed that most terns with prey were arriving from the South carrying herring.

    June 18, 2022 - Cape Sable - Report by Alix d'Entremont.

    Kathleen MacAulay, Bertin d'Eon, Logan Moore and I carried out the tern colony census at Cape Sable. Many details can be found at this eBird checklist https://ebird.org/checklist/S113218558, but the brief update is that we now have 6 Roseate nests, 5 of which are marked. Some of the non-viable eggs and perhaps chicks were likely attributable to a washout.

    Thankfully, the Roseate nests appear to be in areas with slightly higher elevation.

    I wasn't able to read any PFRs. I know at least one Roseate did have one of our plastic bands.

    I could return in a week or two to check on the Roseate nests and attempt to photograph PFRs.

    The aerial image below shows my track during the surveys. You'll see there are two areas of back and forth on land representing the two nearby colonies.

    Thank you, Alix, Kathleen, Bertin, and Logan! Great work!

    June 19, 2022 - Île Chespêque, Pubnico Harbour - from eBird Checklist by Alix d'Entremont (see https://ebird.org/checklist/S113272845).

    Tern colony survey for Université Sainte-Anne and the Canadian Wildlife Service.

    A total of 26 Common Tern nests were found on the southern end of the island. The island is covered in poison ivy and most nests were surrounded by the plant.

    Nests:
    1 egg          (2)
    2 eggs         (8)
    3 eggs        (14)
    1 chick        (1)
    1 egg, 1 chick (1)
    Total = 26
    

    The terns lifted upon our arrival and called for a few minutes, but after stayed in the air mostly not directly above the colony. This may be due to the small size of the colony. In larger colonies, the birds are much more aggressive towards unwanted visitors.

    Thank you Alix and Kathleen.

    June 19, 2022 - Round and Flat Islands ("Mud Island" group of islands in Lobster Bay).

    It was a family outing. Our primary aim was to do a tern nest count on Flat Island.

    Our first stop was to the east side of Round Island to get an estimate of the Atlantic Puffins and Black Guillemots there. We were not disappointed as there were about 40 to 50 of each.

    We then headed west for a few kilometres and landed on Flat Island to conduct the nest count. The total count was 23 with the nests being about half Common Tern and half Arctic Tern. Most of the ARTE nests were in the rocks and gravels on the south side of the pond, while most of the COTE nests were at the far western end of the island.

    Nests:
    1 egg          (4)
    2 eggs        (15)
    3 eggs         (3)
    1 egg, 1 chick (1)
    Total = 23

    Any publicity we can give to the Roseate Terns and the other terns in general, I feel, is good publicity.

    June 26 2022 - North Brother report by Sophie Landry.

    On Sunday morning (June 26), we made a visit to North Brother to check monitored nests,collect fecal matter samples, and swab chicks for Avian Influenza (thanks to Kathleen!). We didnít see any adult carcasses, but we did see quite a few dead chicks,unfortunately including roseate chicks. However, Kathleen identified a new ROST nest on the western ridge that we marked as R70 (see photo)!

    We also visited Dennis Point, where we saw herring mostly between the wharves rather than to the North as we were seeing last year.

    In terms of foraging terns, we saw 4 COTE to the North of wharf 1, 3 COTE in between wharves 2 and 3 and about 15 COTE to the South of wharf 4. We also saw at least 1 ROST further South.

    June 26 2022 - Dennis Point, Lower West Pubnico. Alix d'Entremont reports that in the evening there were at least 8 ROST foraging from 10m to 300m south of wharf #4. He photographed a Roseate Tern successfully catching prey near the construction site for the extension to wharf #4.

    See below.

    June 29 2022 - North Brother report by Sophie Landry.

    We made our way to North Brother on Wednesday morning (June 29) to band more ROST chicks (total of 18 banded) and collect ROST and ARTE chick fecal matter. We noted more chick mortality, however there seemed to be a good chick density on the northwestern and western ridges.

    Shawn remarked a new Roseate nest behind one of the nesting boxes which we marked for monitoring with a wooden stake (R71). This brings our total to 48 confirmed Roseate tern nests on North Brother.

    In the afternoon, Luc, Alexis, and I carried out directional observations from the blind as Shawn did an inventory of foraging terns to the South of Dennis Point Wharf. We saw most terns returning with prey from the East and the most common prey was Herring. We witnessed some kleptoparasitism of large sandlances, and the predation of an ARTE chick by a Herring gull.

    A total of 25 sites used by COTE and 5 sites used by ROST were identified.

    This area was chosen to survey given that recent observations from the blind on NBI have revealed a large number of adult terns with prey returning to the island from the vicinity of lower Pubnico Harbour.† All ROST foraging sites were south of wharf 4 at Dennis Point. It seemed as though ROST were moving south from the wharf and aiming to reach a foraging site around a rocky outcrop about 1.25km south of the Dennis Point.

    Thank you, Shawn.

    June 30 2022 - North Brother report by Alexis Saulnier.

    Thursday morning (June 30), we made our way to North Brother to observe terns arriving to the island with prey. We also set GoPro cameras on Roseate tern nest boxes where we had previously banded chicks to conduct more specific nest watches.

    In the blind, Shawn and I noted our first substantial observations from the North since chick hatching. We also noted that all four cardinal directions were actively being used, the most coming from the East. As Sophie previously remarked, there is a fair amount of kleptoparasitism within the colony, most often for larger prey such as sandlance, pollock and silverside.

    One Common tern has adapted a new tactic, possibly to protect its prey against kleptoparasitism, by carrying the fish halfway in its beak/gullet (see photo). This observation has been seen on multiple occasions on the island since then.

    July 1 2022 - North Brother report by Alexis Saulnier.

    Luc and I sailed to North Brother Island to check the monitored nests, collect fecalsamples from Common tern chicks as well as conduct observations from the blind.

    Since our last nest check on June 26 th , nine Roseate chicks were found dead in their nests. Itís uncertain whether these individuals were affected by the Avian Influenza because no fresh samples could be collected at the time.

    While observing for returning terns, we noted that the most common preys were herring and sandlance. As I was looking towards the South, I observed four Roseate terns arriving with prey from this direction within a single observation block of 30 minutes Ė this marks our highest number of Roseate terns seen during an observation period this year!

    We were also able to observe Common terns feeding bits of fish rejects to its chick, likely foraged from the area surrounding the effluent pipes South of Dennis Point Wharf (see previous observations June 15 th & 16th ).

    A Herring gull also attempted predation of Arctic chicks on the eastern side of the island on three occasions within five minutes. However, the gull was mobbed and chased away by about a dozen terns.

    July 1 2022 - Alix d'Entremont reports from visit to Ball Bar and John's Island.

    Alix writes:

    Bertin d'Eon and I completed a Roseate foraging survey at the Ball Bar and John's Island this morning. It was glass calm.

    We had two groups of Roseates foraging. A group of three east of the Ball Bar and four east of John's Island.

    Below are the details. There was a good amount of north and south movement by Common Terns, mostly east of John's Island and farther south. We saw perhaps 30-40 Common Terns going either north or south during our route. We had a group of 4-5 Commons headed north between Bon Portage Island and Shag Harbour. Otherwise, the groups were smaller Ė singles or 2 or 3.

    Time: 7:56 am
    Coordinates 43.503774,-65.754108
    Terns: 3 ROST, 2 COTE
    Presence of strong current: No
    

    Description of substrate and marine algae: 3 fathoms deep (using rope and anchor), but couldn't see bottom

    I was able to get some photos of the prey that the Roseates were catching east of John's Island. See below.

    Great work, Alix and Bertin! Always good information to have.

    July 4 2022 - Alix d'Entremont reports an update on the Cape Sable Island Roseate Tern colony - Substantial Colony Abandonment!

    Kathleen (MacAulay) and I visited the Cape Sable tern colony to check on the terns following a report on June 30 from Mark Dennis (Cape Sable Island) that the tern numbers in the area was low and that he was not seeing activity at the colony.

    On our arrival, there were about 110 terns loafing on the beach near the colony and only about 40 birds seemed to be landing in the nesting area. Ninety-six (96) of the loafing birds were immature (second-year/third-year types) Arctic Terns. I've never heard of such a large group of non-breeding birds anywhere else in Nova Scotia.

    We walked through the colony with the main goal of checking all nests marked on June 18, 2022. Of the 10 staked nests (all with eggs on June 18), only 3 still had eggs.

    Including staked and un-staked nests, we found three broken eggs, 4 eggs that were buried or appeared to have been washed out of the nest, and 17 nests that appeared in good condition, however, we did not touch the eggs to check for incubation. We were limiting our contact because of the risk of Avian Influenza.

    Three dead chicks were found. One was likely predated and only had the lower half of it left and two were deceased for quite some time and were dried out. No live chicks were found.

    Below are the details for each staked nest. e = egg

    Stake 01 - COTE - 0e (1e June 18)
    Stake 02 - COTE - 2e (1e June 18)
    Stake 03 - COTE - 1e (2e June 18)
    Stake 04 - ROST - 0e (2e June 18)
    Stake 05 - ROST - 0e (1e June 18)
    Stake 06 - ROST - 1e (2e June 18)
    Stake 07 - ROST - 0e (1e June 18)
    Stake 08 - COTE - 0e (3e June 18)
    Stake 09 - COTE - 0e (3e June 18)
    Stake 10 - COTE - 0e (3e June 18)
    

    Two tern nests (1 COTE and 1 ROST) were marked with coffee stirrers on June 18, but neither were found. A nest with 1 egg that was 6 feet west of Stake 6 was confirmed on June 18, and it appeared to have no eggs today.

    In summary, regarding ROST, of the six nests found on June 18, five were checked and only one still had eggs (2 eggs). See the attached images (Stake01, Stake06, and Stake08) for comparisons of the nests on June 18 (left) and July 4 (right).

    Some possible reasons for the abandonment

    Looking at the weather and tide between June 18 (nest census day) and June 30 (when Mark alerted me to the lack of terns), the conditions on June 27 might have contributed to a flooding event. A southerly wind of 24-32 km/h from 19:00 on June 27 to 5:00 on June 28. The high tide at West Head was at 3.01 m at 21:30/21:45 on June 27.

    A strong n.e. wind of 39 km/h occurred at 21:00 on June 23 but did not coincide with the West Head high tide of 2.82 m at 18:30. A washout several years ago has left the area of Cape Sable where the terns nest without protective dunes and at a very low elevation.

    The wrack line near the colony appeared to have moved farther up beach. Also, comparing images of the staked nests on June 18 vs. images from today (July 4), portions of the vegetation have turned yellow. The yellowing of the vegetation may be indicative of direct exposure to salt water.

    Below are the details on the banded ROST. One ROST had only a federal band.

    L0? white on red right leg, federal left. (unsure of code) See Note below.
    BE1 white on red right leg, federal left.
    BA1 white on red right leg, federal left.
    T83 black on yellow left leg, federal right. (image not of good quality, but also seen in the scope)
    

    Looking forward hearing the details about the banded ROST.

    Note: On July 9, 2022, Dr. Jeff Spendelow writes: "Ted: I've been reviewing your blog and I suspect that the red "L0?" PFR that was seen on 4 July at Cape Sable Island probably was "L08" as that is the only PFR in the "L0#" series that has been seen in the past several years where the PFR was on the right leg." Thank you, Jeff.

    I was able to get images of banded ROST (see below).

    July 5 2022 - Alix d'Entremont updates information on Roseate Tern BE1. (From Facebook post}

    Kathleen MacAulay and I found a banded adult Roseate Tern on Cape Sable yesterday (July 4, 2022) with with a plastic field readable (PFR) band with code BE1.

    This individual was born on North Brother Island in 2019, the year of recolonization of the island following the 2017 abandonment. Once they fledge, the adults bring the juvenile birds close to the foraging areas to feed them.

    I found BE1 on Bar Island (owned by Ted D'Eon) being fed by an adult in Aug 2019. This 2022 sighting of this bird is the first since 2019.

    July 5 2022 - North Brother and Pubnico Harbour report by Sophie Landry.

    On Tuesday morning, we visited North Brother to collect fecal matter from ROST and ARTE chicks and band ROST chicks. We now have a total of 28 banded chicks. We noted one new dead ROST chick, but still no adult carcasses.

    In the afternoon, Shawn conducted a survey of terns in the harbour as we returned to the island to collect directional data and set GoPros to observe chick provisioning. We saw most terns returning from the East with prey, and mostly with herring or hake-like fish. We saw more evidence of common terns delivering fish bits likely from fish plant effluent pipes to chicks, Shawn was informed by an employee that they were processing haddock and pollock during this time.

    We were able to identify new PFR bands within the colony thanks to Lucís photos:

    - B12 (red band on the right leg)
    - L45 (red band on the right leg)
    - Z04 (red band on the right leg)
    - LM1 (red band on the right leg)
    - L36 (red band on the left leg)
    - L16 (red band on the right leg)

    July 7 2022 - Lower Pubnico Harbour tern surveys by Shawn Craik.

    ROST foraging locations are generally confined to south of Dennis Point, and notably at lower tide levels around the large rocky outcrop about 1.25 km south of Dennis Point and at higher tide levels in the protected bay immediately north of the East Pubnico light. It seems as though they are taking herring from at least the Pubnico light location.

    COTE are generally foraging in much shallower waters than ROST, and often where there is emergent or submergent marine algae around shorelines (see attached photo of site of GPS point 121). ROST don't seem to associate with these very shallow water areas.

    COTE are clearly more tied to the fishing industry than ROST. For example, COTE are the only terns that have been seen dipping for food at pipes and going for scraps of fish tossed overboard around Dennis Point.

    Thank you, Shawn.

    July 7 2022 - At-sea report by Sophie Landry. le="font-family:courier;"> Alix, Kathleen, and I had an eventful at-sea survey on Thursday morning. We saw ROST foraging in 4 different locations: Up to 4 ROST at Sunken Ledge, up to 3 ROST at The Ball, at least 1 ROST diving and 6 loafing on rocks near Goodwinís Island and 5 ROST near Johnís Island. Alix got some pictures of terns with prey, which all seem to be sandlance, and of PFR band BL1 (red band on the right leg).

    July 8 2022 - North Brother report by Alexis Saulnier.

    Friday morning, we started out our visit to the island by checking the active nests in the colony, where we found no new chick deaths since our last visit. Within the Roseate tern population, we found two newly hatched chicks aged roughly between three and ten days.

    Kathleen accompanied us to conduct the swabbing for Avian Influenza in the tern colony. We saw no definitive evidence that the colony had been infected.

    As Kathleen did her work, we collected more fecal matter samples from Arctic and Common tern chicks to aid in assessing chick provisioning.

    In the afternoon, Luc, Sophie, and I returned to the island to conduct directional observations. We observed no activity from the northern quadrant. However, we observed all three tern species returning from the South, which was our most active direction for the day.

    We also observed a new banded Roseate tern: BB1 (red band on the right leg).

    July 10 2022 - North Brother report by Alexis Saulnier.

    Sunday, we made our way to North Brother Island to observe terns arriving to the colony with prey, as well as conduct nest watches using GoPro cameras set on Roseate tern nests.

    As we observed for terns arriving with prey, we noted that the colony had resumed using all four cardinal directions since our last visit. Moreover, it seemed that most prey brought back to the colony was herring-like fish from the East.

    We also observed the predation of a chick of an unconfirmed species by a juvenile Herring gull, who was then mobbed by the adults of the colony.

    Thanks to Lucís photos, we were able to confirm new Roseate tern bands:

    - L08 (red band on the right leg; previously seen by Alix & team while on an at-sea survey on July 7th)

    - LR0 (red band on the right leg)
    - LU0 (red band on the right leg)

    July 16 2022 - North Brother report by Alexis Saulnier.

    After nearly a week,†we were finally able to make our way to North Brother Saturday afternoon.

    Upon our arrival to Rock Rd, we noticed three birds seeming to belong to the Corvidae family - most likely crows - circling within the colony. After being mobbed by a large number of terns for a few minutes, they abandoned their search for wandering chicks.

    Once on the island, we checked the Roseate tern nests, collected fecal matter samples for both Arctic and Common terns, and conducted directional observations.

    † The walkthrough of the nesting boxes revealed two brand new Roseate tern chicks, likely having hatched that very same day, and two new nests that we later confirmed from the blind.

    There was no evidence of recent chick mortality nor anything to suggest that predation had occurred by the corvids or otherwise.

    Although there weren't many terns arriving to the island, we observed Common terns arriving from the East and South only, mostly carrying hake or herring-like fish.

    Thanks to Lucís photos, we were able to identify a few new bands:

    - B40 (red band on the right leg)
    - LT0 (red band on the left leg)
    - Z27 (red band on the left leg)

    On Sunday, we left for the island in the morning to finish collecting fecal matter samples and conduct more directional observations.

    We were able to collect all but one Arctic tern sample, which we expect to get in the next visits to the island.

    Our directional observations were cut short due to the island being completely enveloped by dense fog, obstructing our visibility. However, from what we were able to observe from the East and West, we observed only Common terns arriving with herring and hake-like fish, respectively.

    July 24 2022 - Mink on Cape Sable - Report by Alix d'Entremont.

    With the recent collapse of a tern colony of 322 nests including 6 Roseate Tern nests on Cape Sable, Shelburne County, the presence of mink on the island might deserve some attention.

    While the ultimate cause of the abandonment of the tern colony on Cape Sable is unknown, mink was likely the cause of complete failure of a tern colony on the nearby Dog Islands in 2021. On the Dog Islands, all eggs of Common Eider and Common Tern were freshly broken when I visited on June 13, 2021.

    The attached image is of a mink on the open ocean facing beach on Cape Sable, about here (43.395195, -65.622834) on July 24, 2022.

    We also went to Cape Sable and did not see any ROST.

    Thank you, Alix.

    August 2 2022 - Jeff Spendelow writes that he has already seen 19 Roseate Terns from North Brother on Cape Cod, Massachusetts.

    Seven of them, red Z76, Z77, Z79, Z81, Z83, Z89, and Z95 were chicks from this year, and the other 12 were adults (red B12, B25, B76, BM1, BS0, L02, L16, L36, L47, LM1, LU1, and Z01).

    It's amazing how quickly our birds get to Cape Cod, where they fatten up before continuing farther south and eventually to South America.

    Thank you Jeff.
