This
is probably the final, FINAL, swift monitoring report of 2019, and oh what a
year it has been! Unofficially, you, our volunteers, have watched more chimneys
and identified more active sites than any previous year. Below we present a
summary of the latest reports received since our last blogpost on August 21st.
First
to Dominion City and a report sent from Dave, a local homeowner and an
email dated August 20th:
‘Just wanted to report another successful nesting season in
my chimney. At least 12 years and running my swift family has been here and
have raised yet another brood. Now the chimney has now gone quiet as they have
now left for another year.’
Having been fortunate to look in the bottom of this chimney, I can
tell you that it is absolutely packed full of swift nesting material.
Margaret and Millie sent a report
from Brandon on the same day with an entry/exit cycle followed by two entries.
In Selkirk, Linda and Nia did not see any swifts at the
Mental Health Centre, also on the 21st.
Blair sent his weekly summary of reports
on the 21st:
‘This week I saw one Chimney swift entering the chimney at 188 St.
Mary’s on August 19th.
For 261 Youville Street, I was watching two swifts over the season
but on August 20, they were not seen, therefore no evidence of a
successful breeding.
690 St. Joseph, was watch on August 21, and no swifts were seen
this night. Since there were 8 entering the chimney at last viewing the
chimney swifts must have started their migration.’
It is sometimes very hard to decipher what has happened with such
an elusive species, but Blair has been brilliant for MCSI in 2019. Thank you!
Also on the 21st Rudolf sent his report from a
waning East Kildonan:
‘I had not seen any swifts in my neighbourhood for about a week,
but today two were near my home.’
Frank and Jacquie sent a report in
from Waterfront:
Jacquie and I parked near MacDonald and Gomez to observe the
waterfront chimneys. It’s hard to find line of sight to both chimneys…
Only one CHSW was seen during the roost hour, and there was one
entry to the 527 Waterfront chimney. That’s it, that’s all.
I really thought we were going to see more activity tonight.’
On the 22nd, Ken and Jan sent an update from
Dauphin:
‘Well we missed last night’s count as we were helping set up our
church for it’s 65th Anniversary till dark so tonight
was the night to check. As I sat watching an empty sky I thought well this is
it for the season but, yes but, after 11 minutes one swift came in and down the
chimney and within 2 minutes it was out and foraging again. It seems the young
still have not fledged from this nest. Every 10 minutes or so there was an
entry/exit cycle but, oh not another but, there was an exit when there was not
supposed to be any birds in the chimney. Just before the end of my observation
period, 3 single birds entered the chimney about 3 minutes apart. It looks like
this pair has recruited a helper for this late in the season. These were the
only swifts seen so everyone else must be heading to a warmer south
destination.’
Barb was on hand to give some thoughts
as to the activity in the chimney though:
‘Thanks so much for sending the summary along Ken…I think you’re
likely in the post-fledging phase with flight training. The Aug. 14th activity
looks suspiciously like touch ‘n’ go fledgling activity; it was triple the
activity rate seen the previous week.
Just for comparison, the ST A fledglings seem to anchor departure
for 7-10 days minimum, so Aug. 22 in your chimney is nominally 1 week
post-fledging. I think they could be gone – successfully, with juveniles in tow
– anytime now and just start the southern trip slowly.’
Barb
is such an asset to MCSI!
Earlier
on the same day, Katrina had seen zero activity at the zoo tower over an
hour monitoring session. It seems these birds may already have migrated.
The
most excitement came from Brandon. Margaret and Millie had 5 swifts in
the chimney, including some iffy entries. Yes, this chimney did it again and
fledged a family of up to 3 young.
Robert
and Donna counted 4 swifts using the large stack at the Mental Health
Centre in Selkirk on the 22nd. Gerald also had 2 swifts use
the southwest chimney at Lower Fort Garry.
On the
23rd, Gerald counted 3 entries and an exit at the St Andrews
Maintenance Compound in Lockport, another successful year at this site by the
looks of things.
Margaret
and Millie only had 3 swifts in the chimney in Brandon on
that evening, but then on the 24th the full family of 5 showed up!
Bob
and Valerie were at New Silver Heights in St James:
‘We observed the chimney at the Silver Heights apartments a
couple of times recently (reports attached). On 23 Aug 2019, it seemed
that young had fledged, but it was very windy and as the birds seemed to be
having difficulties with their entries into the chimney, our counts may not
have been too accurate. We looked again on 30 August 2019 for a while,
but only saw one entry; we hope the other birds have survived.’
One week is ample time for these birds to spread their wings and
seek some better feeding!
On the
25th, Ken sent a lonely report from Dauphin:
‘Yes, I was out this evening to see how the swifts were
fairing here in Dauphin after about a 2 inch rainfall and it appears that the
swifts have missed it and headed south for the winter.’
Another report from Margaret and Millie came in:
‘Two swifts only, entered on Aug 26 – we wondered if they had been
left behind; or, had they been the only two outside the
chimney?
Poor weather kept us from monitoring Aug.27 & Aug 28.
Last evening, Aug. 29 no swifts were seen.’
Gerald also sent another report on the 28th:
‘There are still 2 active chimneys here. Today, Robert Hempler
noted Swifts entering and exiting the Infirmary chimney. This
evening between 8:00 and 8:20 PM I noted 3 Swifts entering the north
chimney at Lockport Bridge.’
Surely not still breeding in the infirmary?
Finally, Barb sent us her final St Adolphe update last
week, documenting the final flaps of swifts as they exit town for another year:
‘Last week, on Tues. Aug. 20th, I did an hour long multi-site
recce in town. Starting at 6:20 PM along the east dyke near the Curling Club,
no Purple Martins, Barn Swallows, Tree Swallows, or Chimney Swifts were seen or
heard. Moving over to the cemetery, a half hour later, yielded the last
sighting of the season. A single swift flew low to the west of the Church ~7
PM. It may have been in the company of a second swift, but the fleeting glimpse
made the bird hard to i.d. with certainty. That was it for over an hour of
monitoring. Things were really winding down.
On Wed. Aug. 21st, I was really wound up. During a 90 minute
roosting hour watch at Club Amical, there wasn’t a swift to be seen or heard.
The absence of swifts made sense and you can’t really want them to linger. The
food supply is running out.
Tues. Aug. 27th and another week has slipped by. Swift watching
may be futile. At 10 AM, it’s 100% overcast, 13 C, winds are gusting to 42 kph,
and more rain is on its way. Another cold, wet, windy morning to challenge
aerial insectivores. Two hummingbirds are sitting and sucking nectar at their
feeder like it’s one big Slurpee dispenser. An adult Barn Swallow is taking
refuge on the plant hanger under the deck roof. No other birds seem to be
active in the area. The Chimney Swift breeding season in St Adolphe is
over.
Now it’s time to send a big shout out of thanks to many, many people
for their contributions to MCSI ’19 – our 13th year of swift-seeking in
Manitoba. My St Adolphe supporters, with their considerable patience and
tolerance, make chimney vigils possible. Other monitors, who contribute to the
big provincial picture by watching, waiting, and counting swift entries and
exits, are sent a huge bouquet of appreciation. It is not a glamorous job, but
it is an essential job, to generate those precious data points. Tim, as
fearless leader, has done a remarkable job of coordinating all the elements of
our program ~ monitoring, stewardship, & outreach ~ that make MCSI such a
success. Frank, our amazing webmaster, is instrumental in linking all of our
activities to the ether zone where we share information and knowledge.
So, keep Chimney Swift issues in mind as the “off
season” descends. We’ll look forward to swift-filled skies (and chimneys)
next spring!’
And with that, the end of this (probably) final monitoring report of 2019. THANK YOU EVERYONE who has contributed to making 2019 a successful year.
Please, please, please send any outstanding reports back to us. We
welcome them even if they are spring straddlers from May!
If you fancy compiling these reports in future, there is an
excellent opportunity to do just that – https://www.mbchimneyswift.com/?p=2145.
