Welcome Chimney Swift enthusiasts!

It’s been another eventful week full of activity to fill you in on! Let’s first have a look at what the swifts have been up to outside of Winnipeg, and then we’ll make our way into the city…
Carman
Staring off with a look at the Carman swifts, Rhonda monitored the Carman Memorial Hall site on the afternoon of July 18th. She observed an entry/exit at just under 20 minutes into her watch, occurring within one minute of each other. As it was the only activity she saw, this could be interpreted as an incubation switch-off between a pair of swifts.
Portage la Prairie
Jana and Gordon watched all three chimneys at the NTL Indigenous Residential School Museum on July 23rd. No swifts were seen or heard during their roosting hour watch, but we still very much appreciate their monitoring efforts!
Selkirk
A true swift sanctuary, Selkirk once again saw a lot of action this week:
July 18th was a busy day at the Selkirk Mental Health Centre (SMHC)! Our Steering Committee Chair – Tim Poole – got some daytime monitoring time in with his daughter, Linnea. They watched all of the active sites at the SMHC campus, beginning with a simultaneous watch of the Taller Tower (T01), the Infirmary-attached Tower (T03), and the Infirmary chimney. At T01, they caught an entry/exit event, with the pair exchange occurring less than one minute apart – incubation seems to still be underway inside this tower. T03 produced interesting results: an initial entry/exit event at 9:59 AM – occurring within 30 seconds – then an exit at 10:30 AM, and then a second exit at 10:39 AM followed by an immediate entry afterwards. Tim wasn’t able to immediately determine what this series of events indicates; however, after some discussion with Barb, they are suspicious that it may point to the feeding of non-brooded young with the presence of a third adult helper. Lastly, at the Infirmary chimney, no swift activity was observed. In his correspondence with Barb, Tim noted how interesting it is that in the past couple of years, this chimney has gone from being the most regular breeding site, to now only being used to roost. To quote him directly, “… [it] just goes to show how dynamic these things can be”!
After their first monitoring session, the father/daughter duo then completed another simultaneous watch of the Smaller Tower (T02), the Stack Replacement Tower (T04), and the Powerhouse/“Yellow Brick” chimney. Tim and Linnea saw four entry/exit events at T02, indicating that the adult swifts are hard at work feeding their non-brooded young! Then, at T04, a single exit was observed just four minutes into their monitoring session, with no additional activity seen afterward. Tim surmised that the only possible stage of nesting that would explain this is incubation. As it’s already getting quite late into breeding season, we’ll just have to stay patient and see what happens here. Finally, the longer intervals between entries and exits that Tim and Linnea observed at the Yellow Brick chimney likely mean that a pair is feeding their still-brooded young inside. Overall, a very productive monitoring session from the duo – and based on these daytime watches, it appears that different stages of nesting are still underway at SMHC!
The following evening, on July 19th, Winona kept watch of her usual apartment building on Main St. Precisely at the start of roosting hour (down to the minute), two swifts made their way into the chimney. One final entry was made exactly at the time of sunset, for a total of three swifts roosting overnight. Clearly, they were feeling rather punctual that evening!
Nia and Linda conducted an evening monitoring session of the SMHC Powerhouse/“Yellow Brick” Chimney on July 20th. One swift was seen flying in the vicinity, to which they made their first entry right near the start of roosting hour at 8:51 PM. An exit was then made two minutes later, followed by a final entry at 9:00 PM. In accordance with Tim and Barb’s interpretation of the activity seen at this chimney, this was perhaps a final exchange between a pair, prior to settling in for the night. No other activity was seen after the last entry – which may also be due to the fact that rainy weather rolled in around this time.
July 22nd brought about another very busy evening in Selkirk! At SMHC, Dennis and Patti kept watch of the Infirmary chimney and T03. The swifts were telling a puzzling story over at the Infirmary chimney: an exit was made at 8:19 PM, followed by three entries at 8:58 PM, 9:09 PM, and 9:35 PM. Then, at 9:42 PM a swift exited the chimney and entered T03. Three more entries were then made at 9:46 PM, 9:49 PM, and 9:50 PM. That resulted in five swifts inside when their monitoring concluded. Understandably, Dennis and Patti couldn’t help but question whether the events pointed more towards nesting or roosting. Barb was able to share some insight, here:
“… it could be that nesting activity is occurring but the total number in suggests a roost has formed. Sometimes combo site use takes place. There was an early exit which was followed by the next event – an entry – over 35 min. later; those aren’t likely feeding intervals. … Tim & Linnea had no entry/exits [on July 18th]. That does support the roost-only interpretation.”
T03 was also incredibly active, with Dennis and Patti capturing 11 entry/exit events! It was very interesting to compare results from Tim and Linnea’s daytime watch to this evening session – both of which are consistent with the feeding of non-brooded young By the end of their watch, four adults settled in to roost. We can hypothesize that at least one of these roosters may be a helper swift, or both may just be individuals keen on roosting at this site, especially since one bird left the Infirmary chimney in favour of T03.
Fred and Nettie had a quieter night over at T01 with an entry at 8:52 PM, an exit at 9:23 PM, and a final entry at 9:27 PM. Perhaps one of the adults went out for a last-minute feed before bedtime? And at T02, Monty and Lisa’s findings align with Tim and Linnea’s – the swifts continued to feed the non-brooded juveniles, with frequent entry/exits observed during their watch. There may be a helper at play here, as well, since three swifts were found to be inside the chimney to roost. Lasty at SMHC, Linda covered T04. Tim was suspicious of incubation during their daytime watch, but during Linda’s session, she saw two entries made at 9:22 PM. If incubation is still underway, a third bird would need to be involved to keep those eggs warm. The mystery at this site grows, and only time will tell us what’s been going on inside that tower! The final Selkirk site of the evening – the Merchants Hotel – was monitored by Winona, but no swifts were observed.
St. Adolphe
Let’s hear directly from Barb regarding the goings-on in St. Adolphe on July 23rd:
“It was a glorious moment in St Adolphe Thursday morning. Twelve swifts were flying low over the parking lot behind the Rectory as we all arrived at 9:25 AM. The birds put on a clinic – V displays by pairs, trio flying, group action, peer ‘n’ veers over the rim of the Church and low level feeding which highlighted their moulting wing feathers. Lewis was a welcome addition to help with a multi-site recce and to count the Max In Air to get a handle on new arrivals which showed up in town Wednesday. Debriefing after the observation session reminded me of 20 years ago when we stood staring at Club Amical, expectantly waiting for the NE fledglings to arrive back to the nest site one night as a Free Press reporter joined us (https://www.winnipegfreepress.com/historic/2007/08/12/look-quickly-chimney-swift-may-disappear-2 ). Two flew into the SE site which had been unused all summer long. Today we watched the group of swifts and wondered how much we’ve learned but how much we still have to learn… and yes, how swift shenanigans through the years keeps you humble.
So, for Thursday July 23:
- Brodeur Bros./Daycare: no entry/exits seen between 9:25 and 11:10; a dedicated hour observation took place between 9:35 – 10:35. No feeding has been detected at this site and it looks as though a nesting attempt has stopped. I saw Max. In Air = 11 at 10:50 and n=12 at 11:02. That is less than the 15 seen Wednesday, but still a very large group of adults to assemble during the daytime.
- The Tower: Rob had eyes on the 9:32 – 10:32 and had 4 entries with 3 being consecutive. As we parked, a swift dropped into the Tower and as we left 2 swifts came out one after the other and then 1 dropped in quickly. The youngsters are being fed very well by their parents and a helper!
- The Church: Lewis had a mission to count airborne swifts and his Max. In Air = 7-11 between 9:33-11:09. Lewis also confirmed ongoing attendance at the Church. A swift had dropped into the chimney before set-up and at least 3 other entries were made, with 2 entering together at 9:56. Today is Day 23 of feeding and the young were being well tended. Fledging = Day 28-30 so we are 5-7 days away from welcoming St Adolphe’s avian congregation to the sky. Can’t wait!”
The mystery in St. Adolphe continues to be the Brodeur Bros./Daycare site. We had hypothesized that rain washing down the inside of the chimney was the reason for consistent nest failures. Despite the new addition of a rain shield on this chimney, however, the swifts still abandoned this nesting attempt. Perhaps the season-end cleanout will provide some valuable clues as to what happened here.
St. Andrews
Gerald monitored the Lower Fort Garry sites on July 21st. At the Fur loft, he recorded two roosting entries, accounting for both swifts he saw in the area. There was a flurry of activity at the Men’s House, with eight entry/exits observed by Gerald. With these intervals beginning well prior to the roosting hour, it appears as though the young inside are non-brooded and hungry, with feedings occurring only minutes apart. One curious thing to note: on his datasheet, Gerald likened the exit seen at 9:07 PM to a crawl rather than a typical swift exit. Based on what was observed, there’s no way to say for certain that this was an unconfident exit by a fledgling and may have simply been an anomaly. It will be exciting to see what continues to unfold here!
The following evening, Gerald and Brittany watched both chimneys at the Lock and Dam Powerhouse. A total of five swifts were seen in the area. The south chimney saw two simultaneous entries just past sunset, with no other activity recorded. At the north chimney, activity was observed prior to roosting hour indicating that feeding is likely underway here. The intervals between entry/exits varied, with the first event happening at 8:30/8:32 PM – a typical duration when the young are non-brooded. However, the second event at 9:29/9:40 PM was much longer. The final entry was then seen at 9:46 PM. Alas, swift activity continues to be rather inconsistent at this site… Do the St. Andrews swifts enjoy toying with us?
Swan River/The Pas
Joel provided an update on our northernmost swifts in The Pas – although no formal site monitoring was conducted, swifts continue to be heard intermittently in the area.
And, in Swan River:
“On July 21st … I observed 3 swifts. Mid evening they appeared to be going into the group of trees between Aspira Dental (3rd St N) and the apartment complex to the west or the very northeast part of this apartment bldg. This is directly south of the school which also happens to have several purple martin colonies.”
Winnipeg
Charleswood/Tuxedo/Westwood
An interesting report from Graham at CMU this week! On July 20th, he conducted a daytime watch of the chimney and saw that eight swifts were frequenting the area. After reviewing prior accounts of the site, it appears as though more swifts have gathered in the area – potentially as they enter the pre-migration phase of their breeding season. There were three entries recorded in succession at 1:41 PM, 1:43 PM, and 1:44 PM. Graham also noted that clumsy entry attempts were made twice during his monitoring period at 1:44 PM and 1:47 PM, respectively. Three swifts entering during the day is curious! Is there the possibility of fledged offspring, here, rather than a pre-migratory gathering? After the triple-entry event, exchanges more typical of non-brooded feeding occurred. We’re certainly keen on seeing what develops here in the coming weeks!
Daniel McIntyre
On the morning of July 22nd, Program Assistant Gibson monitored the Mennonite Church on Home St. No swifts were seen or heard during his session, but he did note that construction appeared to be underway at the site. Two swifts were seen there as recent as 2025 – it’s unclear whether the possible commotion has deterred them, or they’ve simply chosen a new site.
East Kildonan/Elmwood
Brookelyn and Erin watched the MMF tower on July 23rd. An entry/exit occurring two minutes apart was observed ~20 minutes into their daytime watch – an exchange of some sort, possibly brooded young. The next bout of activity came 20 minutes later, with two entries made at 11:12 AM. Following these entries, no other activity was seen. The activity in this tower is still difficult to ascertain – stay tuned!
Fort Rouge/East Fort Garry
On July 20th, a chance encounter between himself and a swift at Dominion Auctions resulted in Tim spotting a daytime entry! The observation period was swift itself – only two minutes long, just as he was passing by – but enough to confirm activity at this site! Quite exciting, as no reports have been made here in the last three years.
The following day, Program Assistants Brooke and Gibson monitored at Lancaster Apartments, and the Wakefield – both of which are Priority Sites. It was determined that the Wakefield chimney had been outfitted with a pest cage, preventing any use by the swifts. There also wasn’t any activity at Lancaster, with the four swifts in the area seemingly uninterested in either site.
Transcona
… If you can believe it, Tim also had a second incidental swift observation on the same day (July 20th), which quite literally led to a new site being discovered! At the Blessed Sacrament Parish Church Hall, a quick five-minute watch led to Tim witnessing an exit out of the chimney. Tim is truly the Swift Whisperer!
North Kildonan
Prior to monitoring with Gibson on July 20th, Brooke had her own happenstance encounter while in line for her morning coffee. As she was in the drive-thru line at McDonald’s, she incidentally caught a perfect view of a swift making a quick exit out of the Curtis Hotel chimney. ‘Twas a perfect way (and a lucky sign) to kick off her day of monitoring!
Mynarski
Brooke and Gibson also monitored two Priority Sites in this neighbourhood on July 20th: St. John’s Cathedral and the Ukrainian National Federation. The former proved to be very successful, with definitive confirmation of nesting within the chimney. Upon arrival, five swifts were seen circling directly over the site, and once monitoring began, the assistants were treated to an up-close view of the feeding exchanges. They occurred at 10:29/10:30 AM, 10:31/10:32 AM, and 11:00/11:01 AM. A total of eight swifts were seen as a group over the site, which led to the assistants being curious about which sites they were all based at. The nearest known sites a quite a ways away, prompting Gibson to do a sweep of the area for any potentially new sites, but none could be determined in that short period. All in all, it’s wonderful to cross off another Priority Site off the list! However, less success was had over the Ukrainian National Federation, with no swifts seen or heard during their watch.
St. Boniface
Blair monitored three sites in St. Boniface this week. On July 20th, he watched Kaljieb Electrics in the late morning. There was only one exchange within the hour he monitored, at 11:53/11:54 AM. The infrequency of daytime activity at this site could signify that incubation is still underway.
Next, on July 22nd, he set his sights on Springs Christian Academy. Nine swifts were accounted for, and instances of daytime chimney use were observed. The first entry/exit was at 10:15/10:16 AM, followed by another at 10:46/10:51 AM. However, the 10:46 AM entry was made by two swifts. The timing of these activities suggests the feeding of brooded young – so perhaps a helper is involved in the care of these babies, and that double-entry event allowed for a switch of the incubating adult!
Blair then visited Nelson McIntyre Collegiate on the afternoon of July 23rd. Unfortunately, no activity was seen.
St. James
The Program Assistants conducted multiple solo monitoring sessions of Priority Sites in St. James, on July 22nd. Brooke visited a Private Residence site, Marner Apartments, Carillon Towers, and St. Anne’s Roman Catholic Church. Overall, she didn’t have an overly successful day, as none of the Priority Sites she kept watch of were being used by swifts.
Gibson’s sites contained more promise! He was able to watch the Stanley Park Apartments and Thunderbird Apartments concurrently and counted a maximum of five swifts in the area. Although no chimney use was seen at the Stanley Park Apartments, he confirmed nesting activity at Thunderbird! He noted that he may have missed the initial entry – but an exit was captured at 10:59 AM, followed by entry/exits at 11:07/11:08 AM and 11:34/11:37 AM. Given the frequency, it certainly seems like these swifts are feeding their young to me!
Later that evening, Breanne and Barret also got out monitoring at the Hilton Apartments. As it’s a Priority Site, it was very exciting to learn that this chimney is being used as a considerably large roosting site! In total, 20 swifts were accounted for. Twelve of them made entry into the chimney, beginning ~20 minutes before the start of roosting hour and continuing throughout the evening. A notably late exit was made by a single swift at 9:57 PM, which begs the question of why would they make such a late exit? Breanne pondered this, as well, continuing to monitor for nearly a half hour afterwards without seeing the swift return to the roosting site. Very odd! Thank you, Breanne and Barret, for confirming the use of this site!
The last site to be monitored in the neighbourhood was on July 24th. Cam monitored at the Assiniboine Inn on the Park during roosting hour No swifts were observed at the site, nor in the surrounding area, despite Breanne having confirmed the site only two weeks prior to this watch. Another mystery as to where those swifts ended up!
… Wow, that was a lot of interesting swift activity to go over! I sincerely hope you enjoyed this glimpse into all the swift-related news across our province, as I thoroughly enjoyed writing it (as always!). I’d like to extend my gratitude to the volunteers who monitored this week, as we managed to cover a lot of ground and visit many sites. Please review the updated Priority Site list to see where we stand, and to see where we have yet to visit! Lastly, please don’t forget to mark your calendars with our next MCSI Blitz on Wednesday, August 12th!
