Keeping you in the loop
We at MCSI believe it is important to keep our volunteers and supporters informed in relation to the latest research and information from elsewhere in the Chimney Swift (and wider swift) world. Here are a couple of interesting tidbits that have come to our attention recently.
We begin around a slightly older story from 2012 that came up again in recent conversation – and if you haven’t seen it yet is worth the look. Soil scientists can find out about the history of an area by studying the structures and chemistry of soil taken from a borehole. In the same way, a biologist can learn a lot about Chimney Swifts from studying guano (or swift poop) remaining in the bottom of a chimney. In one particular study from Ontario (dated 2012), we learn about changes in diet over time linked to the spread of DDE in the wider environment. It appeared that the number of beetles in the diet of Chimney Swifts declined as levels of DDE (a chemical that comes from the pesticide DDT) increased. Beetles were replaced in the diet of swifts by less nutritious ‘true bugs’. There is also an interesting comment about the need for conserving chimney habitats in the final paragraph – we certainly support this view! If you haven’t seen this story before then please look at http://www.sciencemag.org/news/2012/04/clues-species-decline-buried-pile-bird-excrement.
This segues nicely into some news from London Ontario. We are delighted to share a few articles from Winifred Wake. Winifred has long provided MCSI with advice and assistance and carries a huge wealth of experience. She has published a couple of papers, one in The Cardinal and the other in Ontario Birds and we are delighted to have permission to publish these on our resources page. The Cardinal article analyses chimney loss in London, painting a similar picture to that MCSI published in the Blue Jay. You can read this excellent piece at https://www.mbchimneyswift.com/Documents/Wake2016_cardinal.pdf. The piece in Ontario Birds provides an overview of conservation efforts in London between 2004 and 2015. This is extremely relevant to us here in Manitoba as so many of the issues do overlap and this exchange of experiences going forward will only benefit each organisation as we strive to conserve this species. You can read the piece at
https://www.mbchimneyswift.com/Documents/Wake2017_ONbirds.pdf.

Finally, this segues nicely into news from CBC Manitoba! Winifred was the rehab specialist responsible for the final preparation and release of the Manitoba Chimney Swift chicks (take a look here). These birds were released around a roost in London Ontario. A neat segue then as we move onto a nice profile of Tiffany Lui, the Manitoban rehabber who painstakingly cared for the chicks here in Manitoba. You can read more about Tiffany at

Lewis Cocks Swift Champion !
Our latest Swift Champion plaque was presented recently to Lewis Cocks. Many of you will already be familiar with Lewis as a longtime supporter of Chimney Swift conservation in Manitoba. Indeed, Lewis was the closest we have to a founder of MCSI – it was his idea to do something for Chimney Swifts and he was the initial driving force in setting up what we now call the Manitoba Chimney Swift Initiative. Below Lewis answers a few questions about his involvement as a champion of Chimney Swift conservation in Manitoba.2017 MCSI Data added to the Website !
Thank you once more to all our volunteers who spent hours in sunshine, wind and rain collecting Chimney Swift data in 2017. The fruits of your labours can be found in two datasets which we uploaded to the MCSI website today.
Finally, thank you once more for everyone who made 2017 such a special monitoring year for the Manitoba Chimney Swift Initiative. You can see just by looking at the number of sites monitored in 2017 that this has been an absolutely phenomenal year.By the way, we have updated our Monitoring Results page to include links to new information from the Atlas of the Breeding Birds of Manitoba. you should take a look…

St Adolphe Nest Outcome Summary for 2017

Brodeur Bros. was unoccupied the entire year – absolutely no sign of an entry or exit.
A nesting attempt was made at the other 4 sites and 3 attempts were successful (75% success). This ties the previous record of 3 successful breeding attempts in 2013, however, in that year all 5 nest sites had a breeding pair onsite (60% success).
The SE Club Amical nest failure took place on July 10 (Day 6-8). Crop dusting took place outside St A. on July 2, 3, and 9.
The number of fledglings per site was low, although behavioural estimates tend to be underestimates: 1 fledgling at NE Club Amical (behavioural obs.); 2 fledglings at the Church (behavioural obs.); and 3 fledglings at the Main St site (clutch size = 3 = 100% fledging based on physical evidence; behavioural observations estimated n=2 fledglings).
A pdf version of the 2017 Nest Outcome Summary for St. Adolphe may be seen at http://www.mbchimneyswift.com/Documents/stadolphe_2017.pdf
Tim and I are connected to a U of W grad student, Martine Balcaen, who had mosquitoe traps at Howden C.C. on Red River Dr and Marchand Rd (my area northwest of St A.) She noted interesting pulses of mosquitoes between trap locations and shifts in the mass of mosquitoes relative to other species of flying insects. We will follow up with her to see if some explanation can be offered for the successful year of Chimney Swift breeding in St A. relative to the stinking low numbers of mosquitoes in the valley all season long!
The big question to ponder this year is “If mosquitoes never present as a primary food source at the beginning of the season, therefore they do not decline in numbers with mosquito abatement programs mid-season, do Chimney Swifts shift to other prey species with better breeding success?” There’s another big difference this year though: when the hot temp’s arrived the strong winds didn’t; compare to 2011 when rip roaring winds blew for days on end with 30+ C temps – in 2011 the Church nest failed Aug. 2nd on Day 25 (3-5 days before fledging was due) when no bugs could be found.
There’s always a good reason to keep checking in on the birds next year…

End of season update
It’s been over a week with no reports, so it’s very unlikely that any Chimney Swifts remain in Manitoba. Thanks to everyone who has contributed to the Manitoba Chimney Swift Initiative over the course of this busy summer. If anyone still has any outstanding data to submit, it is never too late to email them to us – the more the merrier!
In 2017 you have generated a phenomenal amount of data and below are just a few highlights from a very successful summer.
Number of Communities with Active Monitoring: Volunteers monitored Chimney Swifts in 24 Manitoban communities. The communities in question were: Brandon; Carman, Clearwater; Darlingford; Dauphin; La Broquerie; La Salle; Lac du Bonnet; Lower Fort Garry; Manitou; Melita; Otterburne; Portage la Prairie; Selkirk; Souris; Southport; St Adolphe; St François Xavier; Saint-Jean-Baptiste; Steinbach; Stonewall; The Pas; Wasagaming and; Winnipeg. Swifts were also noted in Morden and the Turtle Mountain Provincial Park.
Number of Sites Monitored: A very impressive 137 sites were monitored in 2017, up from 87 in 2016. This is an awesome effort from a lot of people.
Number of New Sites: We added 39 new site codes to the MCSI database. 32 of these sites were active (i.e. someone saw a swift fly into, or out of, the chimney). New sites were added in La Broquerie, Melita, Selkirk, Lower Fort Garry, Portage la Prairie and Winnipeg (Downtown, South Point Douglas, Fort Rouge, the West End and St James). The La Broquerie chimney is of particular interest. In 2016, volunteer David Dawson was involved in helping to remove an old bees nest and masonry from the top of a second chimney on the church. In 2017 the chimney was used by a second pair of swifts. Well done David!
List of 31 Target Sites: Amazingly, we were able to monitor every single target site identified prior to the breeding season. Of these, 1 was already capped, 1 was later demolished, 13 were unoccupied on the date of monitoring and 16 were occupied. See https://drive.google.com/
Old Database Sites With Chimney Swifts: There are a number of sites present on the database which have no swift records. In 2017 swifts were seen entering a few of these sites in Winnipeg. These were the Nutty Club Food Club on Lombard, VJ’s on Main and 303 Assiniboine Avenue, which turned out to contain a rather large roost. In addition, the Via Rail Station in the The Pas and St. Hyacinthe Church in La Salle were confirmed as active sites.
Number of Volunteers: We are aware of 95 volunteers who have been out and about monitoring chimneys in 2017. This is up from 61 in 2016. The Selkirk Birdwatchers Club led by Gerald Macnee, the Assiniboine School monitors and Gord Ogilvie in Portage la Prairie have coordinated group monitoring in local areas. Frank and Jacquie Machovec also deserve a mention, being always willing to drive longer distances to monitor swifts where no local volunteers are available.
A keen observer, indeed: John Hays watched over a dozen chimneys in and around downtown Winnipeg!
Creative volunteer recruitment: Jan and Ken Wainwright have kept monitoring the Dauphin roost throughout the season over a decade. In an attempt to drum up more local interest in the swift population they put on an evening for geocachers with up to 6 coming along for the show! Swift watches were also organised in Portage la Prairie and Winnipeg and larger blitzes in Selkirk and Souris.
Largest Roost: Jake Peters counted 210 swifts enter Assiniboine School on May 18th. This was the largest total ever counted by MCSI. The largest fall count was by John Hays at 303 Assiniboine Avenue in Winnipeg, a total of 102 on August 6th.
Confirmed Breeding: It is not always easy to determine nesting success but in 2017 we did have a few sites confirmed. From the information supplied we think we have successful breeding in Brandon, St Adolphe, Winnipeg, La Broquerie and Dauphin. Active nesting behaviour was observed in a number of other places – including The Pas for the very first time.
Latest fledgling swifts: Margaret and Millie had a later brood in Brandon. The fledglings were last noted on August 28th having first been confirmed on August 24th. The hatch date is unknown – but this does appear to be a late record for Manitoba.
Latest roosting birds: The Selkirk Birdwatching Club managed it again! Gerald, Carol, Robert and Donna had a single swift at the Selkirk Mental Health Centre on September 2nd. Cal Cuthbert also had birds at the Red River College in Portage la Prairie on August 30th.
Latest birds in air: Rudolf Koes noted a swift over Assiniboine Park on September 3rd flying quite high over the river.
Although the swifts have migrated to their winter feeding grounds in the Upper Amazon, MCSI will continue to be active on a number of projects. Keep an eye on our website during the winter for latest news and developments.
A Happy Ending
The last remaining swifts are still lingering in Manitoba with birds still being counted into chimneys in Brandon, Portage la Prairie and Selkirk. Well done everyone involved! We will give a comprehensive update soon.
However, the subject of this blog is of a swift rescue par excellent by Bird Studies Canada’s own Christian Artuso. If you cast your mind back to a previous blog, we left it with a story about Christian rescuing a swift from a chimney in a private household in Tuxedo. The story went as follows:
‘An adult bird had slipped down through the gap in the damper and chimney and could not get back up. I was able to very carefully use my two (large) cupped hands to coax the bird upward to the bottom of the damper (having covered the fireplace glass with black plastic and poking my head through it). The swift perched upside down clinging to the bottom of the damper for a split second and from there i gently coaxed it through the damper gap. Once through the gap the swift flew straight up and straight out – no signs of damage to the wings and clearly no impediment to flight.. impressive in fact. During this process chicks were audible but i could only see one wall of the chimney and could not see the nest…’
That was the 25th July. On the 27th Christian and then Frank and Jacquie Machovec returned to monitor the adults to ensure they were still actively feeding the chicks. Christian reported at 2:52pm:
‘Things are looking good. the adults have been in and out of the chimney at least three times so it looks like they have found their babies. I will come by after 5 pm to check again and I can update you then but more than likely the plan of attack will be to leave the parents to do the job…’
Everything seemed fine. Christian noted at 5pm that adults were still entering and exiting as normal. When the owners of the house returned home from work that evening and chatted with Christian outside, they decided to go in and just check that everything was ok in the fireplace.
And a good job they checked! Here again Christian takes up the story:
‘After Frank and Jacquie had found a good pattern of entries and exits in the late morning and early afternoon, I went back at 16:30 and observed two entry/exit cycles between then and 17:30. On both occasions one adult entered and left again within 7 minutes. The family came home around 17:30 and I greeted them in the driveway. I suggested we check the fireplace just in case, thinking that after doing that I could go home and call it a day. Well, I was horrified to see baby swifts in the fireplace.
Not knowing how long they had been there since slipping through the damper gap a second time I decided to act quickly. I put two swiftlets in a box and left one clinging to the fireplace wall (far enough out of my way) and then reached my head in to look up with a flashlight. I could not see any gap in the sponge, paper and cardboard I had stuffed between the damper and the wall but obviously something was not right. Removing the sponges and paper I found that there were five baby swifts in total since one was clinging on the brick wall half way up that I had not seen previously. Since none of the babies looked injured in any way I hatched a new plan to try to get all the babies to cling to the wall and then somehow to try to force the jammed damper into a closed position.
This was not easy at all! The chimney was slightly tapered above the damper and I needed to get the babies above the taper (to maximise the chances that the adults would feed them) and then I needed to encourage them to leave my hand and grab the wall. This meant I had to jam my head right into the chimney with eyes closed due to all the falling soot, carefully cupping a baby swift in one hand, as I slid my arm through the narrow damper gap all the way to my shoulder. I got several scrapes and bruises, especially on my inner biceps doing this but it was the only way to get my arm in high enough. One by one, I picked up the babies and coaxed them onto the wall (the same wall as their sibling “on high” assuming it was the best seat in the house). Their gripping power was staggeringly strong for such little creatures but their reluctance to leave my hand was also noticeable. When they finally latched onto the wall I had to hold my finger against their back and gently back my hand away. It took some time but finally I could see all five clinging to the wall in what I considered reasonably good positions. The next trick was to try to move the damper into the closed position by scratching away as much soot as possible and gently wiggling it back and forth. Crystal brought a screwdriver and some WD40. I didn’t use the WD40 in the end because, after much scraping and wiggling, I got the damper loose enough that we could turn it into the closed position. It still doesn’t work by turning the knob alone but it opened and closed with Crystal turning the knob and me pulling on it from inside the fireplace. What a relief that was. To be absolutely sure, I wedged a sponge under the damper and we made sure it was good and locked in place. Just before triple checking and closing the damper, I noticed that two of the baby swifts had climbed upwards, one of them had made almost a foot of vertical gain and the other an inch or two. All five were cling to the wall. This was a good sign.
When all was said and done, I was completely black – hilariously so in fact. My face was as black as though someone had smeared it liberally with shoe polish and my hair was looking like a sooty grey Afro-frizz. I can tell you that when I caught a glimpse of myself in the car mirror I got a shock! Rather than audition for a black and white minstrel show, I went home for a LONG shower and a whole lot of scrubbing!
Once a little more respectable, I went back at 19:20 and observed one adult enter at 19:25 and exit 13 minutes later. Then at 19:55 two adults entered the chimney almost simultaneously. One exited after three and a half minutes but the other had not exited by 20:20 when I decided to leave. Obviously the adults are feeding and that is the most important thing. I couldn’t stand really close to the chimney and watch the top at the same time so I could not hear them; however, the pattern of entries and exits throughout the day (thanks to Frank and Jacquie for great work monitoring) and after the intervention made me feel confident we had given them the best shot we could. A confab with Barb confirmed that the pattern of entries and exits is good for chicks of this age. Fingers crossed none got dehydrated in the fireplace and that all five make it through!’
Following this, Christian, Frank, Jacquie and on one occasion, Tim, took up the mantle of monitoring the swifts, checking everything was ok. During this period all reports were sent to Barb and Rob Stewart and they gave some brilliant interpretation of the behaviour being observed. The good news was that somewhere around August 11th and 12th Crystal, the homeowner stopped hearing the chicks in the chimney and they fledged (we have since confirmed this from the contents of the chimney).
This success would not have happened without the support of Crystal Dalgleish and her family and we were delighted to hand over one of our legendary plaques. We will also work with the family to fix the damper.
Thanks also to Frank, Jacquie, Rob, Barb and of course Christian

New Fall Roost Discovered in Downtown Winnipeg
Last week Patricia stepped outside a friends apartment and noticed a large group of swifts forming over the Donald Bridge. In the following few minutes, 19 swifts entered the northern chimney on an apartment block at 303 Assiniboine Avenue.
A few days later, Marie-Eve, a fellow U of M postgraduate biologist whom Patricia had been visiting that fateful first evening, watched 40 swifts enter the chimney from her apartment overlooking the chimney, plus 2 popping into the southern chimney on that same building.
John followed up again last night and counted an impressive 103 swifts, with a possible exit thrown in for good measure.
It is very common for large roosts to form during fall migration, although this is the largest recorded in Winnipeg since MCSI began formal monitoring.
The swifts are beginning to gather for migration but watch out for any further evening gatherings as they prepare for the long journey to South America.
Swift viewing highlights
The end of July is almost nigh and it feels like the right time for an update on the exhausting summer of swift activity. Highlights of the previous month include new active chimneys in The Pas, Portage la Prairie and Winnipeg, a swift rescue and more!
First some context from the month of July, and the best way we can do that is to paste some of Barb Stewart’s reports from St Adolphe. On July 3rd Barb reported: ‘I have checked in on all of the St Adolphe nest sites over the last two days. Brodeur Bros is still unoccupied; no primary occupation during the spring arrival phase and no secondary arrivals of late migrants/dispersing locals in late June. The SE and NE Club Amical, Church, and Main St sites are all occupied and all pairs are incubating eggs. There are quick exchanges with ~ 50-70 minutes between visits. Yesterday at the Church, I saw repeat hovers at the ends of a dead Manitoba Maple branch. It is a tree with a newly exposed flight path now that the old convent/school/nursing home has been demolished. Nest building does stop completely with hatching so that is another indication that incubation is still ongoing. There was one interesting entry at the Church with a swift blowing by a goldfinch that was perched on the chimney rim.’ Her update on July 13th was as follows: ‘What a difference a few days makes…in St Adolphe, the SE Club pair failed to show up on Monday (July 10) and again today (July 13) – the nest has failed. However, feeding juveniles has moved into the non-brooded stage at the Main St, Church, and NE Club sites. Consecutive entries/exits sure help make monitoring definitive! The NE Club Amical pair were feeding 4 X hour and the other 2 sites were 3 X hour. Lots of continuous, low flying action this morning and again, some buzz-by’s over the artificial tower top but no entries. The group size in town was 7 in the air while 2 adults were in the NE Club, so at least 9 swifts are in town.’ And on July 24th: ‘In St Adolphe, the earliest fledging date has been July 27th; the latest on record are Aug. 11, 12, and 16th; most have occurred between July 30 and Aug. 6. Currently, 3 nest sites are active in St A and while I need to put my head down into the datasheets to fine tune details, this year’s fledglings are due out ~Aug. 1-4th. I checked in with the St Adolphe sites this morning and all 3 of the active sites were still ok. There was a lot of low flying feeding and activity by the swifts; recently fledged Purple Martins and adults added to the chaos. Quite fun chaos though. Wind was the issue – lining up on the chimney tops for entries was tough on occasion.’ Elsewhere, it’s been a busy month with a lot of monitoring and a fair few new sites to boot. Joel in The Pas reported in on July 18th: ‘Yesterday at 7:10 am was getting gas at a station adjacent to a long suspected swift site at 5th and Larose. As usual look up at the chimneys hoping to see an entry/exit. While their sitting on the chimney is a small bird, the angle and crouched position make it impossible to id. Could it be a fledgling swift, I ask myself, hoping. Realize my truck has an air lock so it takes quite a long time to fill. It was getting to the time my tank is just about filled when whoosh a swift comes out of nowhere and enters the chimney. This rousts the perched bird which turns out to be a juvenile sparrow, when swooping through the air comes another swift to escort the sparrow away.’ Further south and Ken and Jan in Dauphin are expecting their first confirmed fledgling swifts in the coming days. This site has been a regular large roost but in 2017 a pair have decided to attempt nesting for the first time in 10 years monitoring. Fingers crossed that the nest will be successful! In Brandon, Margaret and Millie were still reporting 2 swifts in the Orange Block as of July 19th. Further south in Souris and back to June, Katharine gets the award for most dedicated volunteer for 2017. Following her very early morning Breeding Bird Survey, Katharine spent the entire day in Souris monitoring swifts. She checked four sites and had successful entries at the museum and Chocolate Shop. Great effort! Heading east and to Portage la Prairie. Gord has just reported a new site in the west of the city with non-brooded young and also that a pair is in residence in the Southport site. There was also news that swifts were checking out some of the historic buildings in the Fort La Reine Museum earlier this spring. On July 5th there was a blitz night with Janice recording breeding activity in the main chimney at the Trinity United Church and a roost in the second chimney. Cal also had a pair in the Victoria College chimney that evening. Cal and Betty continued monitoring the church one evening per week with both chimneys occupied by swifts. South to the area around Morden and Carman. Paul and Valerie confirmed daytime activity on the Darlingford Museum again for 2017. On July 26th Patricia and Tim noted at least 5 swifts in Carman and Patricia counted 3 entry/exit cycles on the Memorial Hall. Later that same day, Matt, Tim and Patricia observed 2 swifts in Morden but no entries. If anyone lives down there, please keep an eye out for swifts! They also checked the towns of Miami, Roseisle, Homewood and Roland, found some interesting looking chimneys but no swifts on the day. The southeast, an area which is probably under-observed when it comes to swifts has thrown a tantalising observation. Carla Church from the Manitoba Conservation Data Centre thought she heard swifts in the town of Roseau River on July 12th. if anyone is in the area please take a look! A little further north and Frank and Jacquie counted 5 swifts at Providence College using 2 chimneys but unfortunately not showing any breeding activity. Frank and Jacquie had more luck on their return to Winnipeg. On the 24th they found a new site at 415 Mulvey and noted numerous entry/exits including a possible early juvenile tumbling awkwardly. John has been his energetic self. We make it that in the month of July alone John has watched at least 14 chimneys. He found a new site at 486 Sherbrook and another at 527 Waterfront. Another of the sites John was watching, the Bardal Funeral Home on Sherbrook was discovered by Christian one evening while visiting a friend in the area. In the Exchange, Tim found a new site at 54 Adelaide while out on his lunchtime stroll and as of today (the 26th), the adults were still feeding young in the chimney. Ron also noted daytime activity at VJ’s on July 5th. In Osborne Village, both Marie-Eve and Patricia confirmed use of two new apartment blocks. Patricia also discovered a new site on the Mount Royal Apartments on Portage with daytime entries on July 20th. This was on the western end of a group of apartments with a known site on the eastern end. This chimney on the New Silver Height Apartments also had daytime entries and exits, with adults likely to be feeding non-brooded young. In St Vital, Badal counted 2 swifts at the Good News Fellowship chimney but nothing at Christ the King School in mid-July. Heading north along the Red River and congratulations to Gerald, Robert, Nia, Linda, Carol, Sharon, Ray, Sybil, Ray, Dorothy and Virginia from the Selkirk Birdwatchers for a terrific one night blitz in Selkirk and Lower Fort Garry. We now have two occupied sites at Lower Fort Garry including a roost with 4 swifts. Gerald also added yet another new site in Selkirk, the Lord Selkirk Hotel having 5 swifts. 24 swifts were counted at the large stack chimney at the Mental Health Centre as well. This dedicated group continue to provide excellent coverage in this area! Christian was also called on by the Dalgleish family in Tuxedo to perform a swift rescue act when a swift was found in the fireplace. the family managed to continue the swift in the fireplace before Christian arrived. He tells the rest of the story as follows: ‘An adult bird had slipped down through the gap in the damper and chimney and could not get back up. I was able to very carefully use my two (large) cupped hands to coax the bird upward to the bottom of the damper (having covered the fireplace glass with black plastic and poking my head through it). The swift perched upside down clinging to the bottom of the damper for a split second and from there i gently coaxed it through the damper gap. Once through the gap the swift flew straight up and straight out – no signs of damage to the wings and clearly no impediment to flight.. impressive in fact. During this process chicks were audible but i could only see one wall of the chimney and could not see the nest…’
Phew, all ends well then! Over the next couple of weeks we will start to see a change as swift adults are joined in the air by juveniles. So please keep those reports coming, we really appreciate them!

The end of July is almost nigh and it feels like the right time for an update on the exhausting summer of swift activity. Highlights of the previous month include new active chimneys in The Pas, Portage la Prairie and Winnipeg, a swift rescue and more!
