update! CHEEP ACCOMODATION IN DOWNTOWN TORONTO

in Conservation / Director's Blog / News by Su Rynard February 13, 2022 0 comments

UPDATE: Feb. 2022. In the fall of 2021 the inside of the replacement habitat chimney was inspected. (There is a special hatch door in the design at the bottom of the chimney for this purpose.) One nest was observed on the side of the chimney eight feet from chimney base, and two half eggshells were observed at the base of the chimney under the nest. The conclusion is that it appears the chimney is successful in providing habitat for producing more young. This is great news, because, as far as we know, this is the second replacement chimney structure in the province Ontario to have confirmed nesting activity.

UPDATE: July 2021. Swift (multiple swifts) interest and activity has been documented around the chimney. Confirmed at least two birds overnight in the chimney, possibly this pair is nesting.

When the celebrated Toronto firm Kohn Shnier Architects was awarded the contract to build a new school for the Toronto Catholic District School Board in Toronto’s Christie Pits neighborhood, they didn’t expected that the first ‘shovel in the ground’ would be for the neighborhoods special seasonal resident, the Chimney Swift.

Chimney Swifts are among the finest aerial insectivore acrobats in the bird world.

During the day they are often seen in small groups, chittering and circling high in the sky. Often mistaken for bats, they swoop and dive with open beaks scooping up insects all day long. You’ll never see a Chimney Swift perching on a branch or at a bird feeder. In fact, they can’t perch, as their long claws are designed to cling to vertical surfaces. Amazing yes, but this also limits where they can find suitable places to nest, and like other aerial insectivores, Chimney Swifts are in decline.

One of the main problems this bird is facing is a biggie — loss of habitat. A few hundred years ago they lived primarily on cliff faces or in hollow trees, but when we colonizers altered the landscape to make way for civilization these birds had nowhere to go. Interestingly, they adapted to the new world by choosing to nest in something that to them, possibly, resembled the hollowed tree cavities in their old stomping grounds: chimneys. Now Chimney Swifts are listed as threatened under the Ontario Endangered Species Act (ESA).

Before building the new school, the old school had to be torn down. Demolition was set to begin when a notice came from Ontario’s Ministry of Natural Resources and Forestry (MNRF) stating that the school was a known habitat for Chimney Swifts. The news came as a surprise to architect Marty Kohn, “We received notice from MNR indicating that we had to go through an investigation.” Ultimately, the demolition was postponed and could not proceed until replacement habitat was built.

With city permits in hand, demolition was set to begin when a notice came from Ontario’s Ministry of Natural Resources and Forestry (MNRF) stating that the school was a known habitat for Chimney Swifts.

Although the MNRF offers minimum requirements for building new habitat it’s up to the architects or developer to come up with the final engineering and design. Fortunately for the Swifts Marty was on their team. Marty discovered that about fifty Swift towers have been built in Ontario. Twenty were masonry constructions, the rest were timber. Unfortunately, none of the timber structures have been occupied by Swifts, and of the remaining masonry towers, only one has resident Swifts. So, masonry it would be.

The resulting free-standing chimney is a wonder to behold.

Towering 10 meters high, the stand-alone chimney is set apart from where the new school building is to be constructed. The exterior is clad in white brick to match the overall project design. Under the brick is a layer of insulation, then a cinder block structure. The exterior brick is pointed, while the interior has rough mortar joints, making it suitable for nesting. The opening is the recommended 35mm wide, enough to allow access for the Chimney Swifts. The structure also has a vent for airflow and a small access door, allowing for annual maintenance and for monitoring the temperature. The cost was $125,000.

When the building is completed, on-site information on Chimney Swifts will be available, and the school can become involved in monitoring activities.

On the whole, awareness of Chimney Swift habitat is extremely low, not just among the general public, but also among urban planners and developers and building owners. Given the rate at which old chimneys are being capped or demolished, it would be beneficial if there were more builders following the lead of Kohn Shnier Architects. It would certainly be helpful for developers to be informed of the MNRF regulation in advance so they could plan and budget accordingly.

It is interesting to note that in the spring 2018, the newly elected Ontario Government moved Species at Risk from MNRF to the Ministry of Environment, Conservation and Parks (MECP). It’s unclear if MNRF still has a role to play in the implementation of the ESA as MECP has little operational presence across Ontario. Importantly, in order for the MNRF to act to protect Chimney Swift habitat, they rely on reports from citizen scientists who monitor and participate in Swift Watch groups.

Around the world animal habitats continue to shrink as human population increases.

In the case of Chimney Swifts, after its original habitat disappeared they adapted to chimneys, but now these are disappearing too. While many nesting sites remain in the downtown areas where there is a greater concentration of older low-rise buildings, these are now being replaced with condos and new developments, leaving many demolished chimneys in their wake.

Can we, with our modern ways of living find better ways to share our habitat with our animal companions?

Soon this idea will put to the test. Chimney Swifts are impressive migrants, wintering in South America and returning to eastern North America in the spring. And this year, we will be watching! The hope is that these threatened birds will rest and roost in the new tower and ultimately a pair will successfully nest and raise the next generation.

If you happen to be at the north end of Christie Pits on Barton Avenue twenty minutes before or after sunset please watch the new tower! Share your swift sightings with ebird or another citizen science app, and with @BirdsCanada (OntarioSwiftWatch@birdscanada.org) and @SongbirdSOSfilm. If you want to know more about spotting Chimney Swifts this spring and summer, we will be posting more in the weeks ahead. Stay tuned!

Note: The official Birds Canada Swift Watch is canceled due COVID-19. But you may be surprised what you can see from your own back window, patio or roof deck.

The Jackman Humanities Institute Program for the Arts presents:
Heeding The Messenger (Songbirds and the Scale of Climate Change)
Friday Nov 6, 2020
in cooperation with the IHPST, Victoria University, and Cinema Studies Institute,
University of Toronto

Heeding the Messenger is a one-day interdisciplinary event inspired by, and culminating in, a screening and round table discussion of Toronto film-maker Su Rynard’s 2015 documentary film The Messenger. Echoing the mythical role of birds as divine messengers, the film sets out to discover what we should learn from the recent and rapid decline of migrating songbirds around the globe. In concert with scientists, naturalists, activists, museum curators and concerned citizens, Rynard follows the migration routes of songbirds to critical points of observation–from downtown Toronto to deforested Costa Rica, drought-ridden Turkey, and Manhattan’s 9/11 memorial–seeking insight into the ecological and environmental causes and consequences of songbirds’ decline.

Heeding the Messenger brings together STS and sound studies scholars, participants in Rynard’s film, and the director herself to explore the themes and issues raised in the film and by the plight of songbirds in general. Engaging local and global perspectives, speakers and participants will speak to multiple aspects of contemporary climate change, offering a multivocal and multifaceted account of affective and ecological dimensions of the Anthropocene.

Birding in a Pandemic

So, let me guess…

So, let me guess… you had been planning a once-in-a-life-time nature safari this summer to explore the hidden secrets of the Amazon rain forest of northern Peru, right? And then an unexpected global pandemic put those plans on hold and now you’re stuck at home staring out your kitchen window and you’re feeling isolated, not just from your fellow humans, but from the natural world. Am I close? Well, I’ve got great news for you, Nature is about to save you the trip to Peru and instead will be parading past your window in the coming weeks and throughout the summer months. Lucky you!

Hundreds of species of birds migrate from South and Central America on their way up to Canada’s Boreal forest, but I’d like to bring your attention to one species in particular that is summering alongside those of us who live in cities and small towns in the central and eastern states from Texas up to Minnesota and into southern Ontario and Quebec and out to the Maritime Provinces and states along the eastern seaboard. Unlike migratory birds that you will only see in passing during the migration season, the Chimney Swift will be staying close to home, close to your home.

Much like humans, Chimney Swifts have adapted their way of life to live mostly in cities and towns rather than forests. Who wants to live in a rotten old tree when there’s a perfectly good apartment building waiting for you? But unlike humans, the overall population of Swifts has dropped dramatically over the years. So much so that they are now considered a species at risk in many regions.

All birds are pretty spectacular when you get to know them, but the Chimney Swift has superpowers beyond the scope of most species.

All birds are pretty spectacular when you get to know them, but the Chimney Swift has superpowers beyond the scope of most species. First of all, they don’t spend any time on the ground. Unless it’s nesting season, these birds take flight in the morning after sunrise and they won’t land again until sunset. They are areal insectivores, so they take their breakfast, lunch and dinner on the fly, literally. There’s no hopping around looking for worms, or grabbing a bite at the feeder, no splashing about in birdbaths and certainly none of this bird-on-a-wire stuff. Swifts are up in the sky gathering food all day long. But don’t think that Chimney Swifts are all work and no play. More than most birds, the Swifts are community oriented, so you will often see them flying in small groups, sometimes in formation like tiny, feathered fighter jets. The constant chittering sound that they emit is probably some kind of air traffic control (“On your left! On your left!), but to our ears sounds more like the gleeful chatter of passing school kids on a Friday afternoon. (Remember when children used to go to school?) They really sound like they’re having a good time.

If you want to see a Chimney Swift, there’s a good chance that if you live in a city, all you need to do is tilt your head and look up in the sky and wait.

If you want to see a Chimney Swift, there’s a good chance that if you live in a city, all you need to do is tilt your head and look up in the sky and wait. If you see some Starling-sized birds making erratic bat-like movements, those are probably Chimney Swifts. You’ll know because you’ll be able to hear them chattering to one another. But if you want to see a Chimney Swift perform a magic trick that no other species can do, a miracle so beautiful and profound that you’ll half expect David Attenborough to show up and pontificate, well, for that you’ll need a bit of patience. And a chimney.

Not just any chimney will do, you’ll want to find one with good swift-potential.

Not just any chimney will do, you’ll want to find one with good swift-potential. The best place to start is an old church, a school or an older industrial building. Swifts need a certain amount of clearance inside the flue, so although they sometimes resort to small residential chimneys, they prefer the wider, more industrial kind. And if a chimney has a metal liner poking up, forget about it, Swifts prefer exposed-brick interiors. Also, if there are too many trees or other obstructions close to the chimney, that’s another deal-breaker; they’ll only settle for uninterrupted access.

Timing is everything. Within 15 minutes on either side of sunset is when the Swifts are most likely to enter the chimney they are occupying.

Timing is everything. Within 15 minutes on either side of sunset is when the Swifts are most likely to enter the chimney they are occupying. So don’t bother with the other 23 and a half hours of the day, but for that one half hour, keep your eye on the chimney. Stand where you can see it clearly silhouetted against the sky. Sometimes there will be a few fly-overs in the minutes leading up to their dramatic entrance, but more often than not they’ll appear out of nowhere. It often happens so fast you might be left thinking: “did I actually see what I think I just saw?” If you’re lucky, you might see one or two Swifts entering a chimney. But if you are REALLY lucky, you might encounter a roost, where dozens or even hundreds of Swifts will enter a single chimney. Bearing witness to such a beautiful phenomenon just might change your life.

Sadly, due to Covid-19, it is not possible right now to register your sightings on some of the conservation websites that are working to track these endangered birds such as the SwiftWatch program organized by Birds Canada. (although it is still a great resource for information on Swifts). https://www.birdscanada.org/bird-science/swiftwatch/

But eventually things will open up again, and you’ll be able to contribute your citizen science data there or locally where ever you live. In the meantime, there are other useful apps such as iNaturalist or eBird where you can register your findings. Or, you can simply look up and enjoy the show.

Pesticides Make Migrating Birds Lose their Way

in Conservation / News by SongbirdSOS December 14, 2017 0 comments

Guest Blog post by Dr. Bridget Stutchbury

Pesticides are widely recognized as a risk to birds that forage in agricultural environments especially during migration. Since many current use insecticides are potent neurotoxins, we speculated that they could have behavioural effects in small songbirds landing in agricultural fields during their journey north if they consume tainted seeds or granules when they stop to fuel.

So we designed a study to test whether low level exposure to 2 widely used insecticides – imidacloprid (a neonicotinoid) and chlorpyrifos (an organophosphate) could disrupt the migratory ability of a wild-caught songbird. White-crowned sparrows, a common seed eater, were captured on migration and held in captivity at the Facility for Applied Avian Research at the University of Saskatchewan. After acclimation, we exposed the birds to either a low or high dose of either imidacloprid or chlorpyrifos at concentrations they could realistically encounter in the environment, and tested their orientation in a series of Emlen funnel migration trials before dosing, during the 3 day exposure, and during the recovery period.

What surprised us was how sensitive and rapid the effects were, particularly to imidacloprid.

The birds showed a significant loss of body mass and signs of acute poisoning (lethargy and loss of appetite). The migration trials also showed that birds completely failed to orient or changed their northward orientation, whereas controls continued to behave as expected. While the chlorpyrifos treated birds did not show toxicity in terms of weight loss, they too lost their migratory orientation. In the wild, we calculated that these effects would be seen if the birds consumed just a few treated seeds or granules mistaken as grit.

We were encouraged that most birds survived, and could recover following the cessation of dosing, but the effects we saw were severe enough that the birds would likely experience migratory delays or changes in their flight routes that could reduce their chance of survival or cause a missed breeding opportunity.

Since these chemicals are used over vast areas of North America and the timing of application directly overlaps with spring migration, the results of this study raises serious concern about the risk of increasing use of seed and granular pesticide treatments to millions of migrating songbirds.

The Ortolan Bunting Will Finally Be Off the Menu in France!

in Conservation / News by SongbirdSOS December 13, 2017 0 comments

“We have won our battle against Ortolan Bunting trapping and the phenomenon is basically wiped out from Les Landes.”

THE MESSENGER took audiences into the fields of Les Landes, in south-west West France, to witness the illegal hunting of Ortolan Bunting, a practise that was decimating local populations. Now, the Ortolan Bunting will finally be off the menu in France! No other European songbird has declined as rapidly in recent years, with an overall decline of 84% since 1980 due to poaching and intensive agriculture – this, despite hunting of the species being forbidden by French law since 1999 when it became a protected species. Because the Ortolan dish is considered a cultural tradition, authorities had often turned a blind eye to the activities of poachers.

For the past 10 years, LPO (League for the Protection of the Oiseaux) the BirdLife International partner in France has been fighting this illegal practice on the ground, and also in the air, where alongside CABS (Committee Against Bird Slaughter), they have been identifying trapping sites and releasing the birds, before alerting the authorities. Until recently, these interventions were the only way to identify and prosecute the poachers, who operated with the blessing of local elected officials and hunting officials, and who claimed that the state “tolerated” these practices. Indeed the authorities wouldn’t file charges for installations of 30 traps or less. More on the practise and new developments in this article from Bird Life International.

The French Ministry of the Environment requested guidelines to study the Ortolans on a continental scale.

Frédéric Jiguet from Museum National D’Histoire Naturelle in Paris, (featured in The Messenger) partnered with other scientists from more than 12 countries across EU to conduct the study. He also worked in partnership with ONCFS (French Hunting & Wildlife National Office).

Frédéric Jiguet and his colleagues research work helped convince French Ecology Minister, Nicolas Hulot, to call for a definitive end to the hunting. This was followed up in the field with a high pressure from the police this past fall, so there are now very few poachers.

The main conclusions are that the numbers migrating by south-west France are estimated on average only 81,000 pairs (300,000 individuals including juveniles), with a recent decline estimated between -20% and -30%, while the overall trend of birds using the western flyway, or the eastern flyway, is a decline of lower amplitude estimated between -10% and -20%. The birds flying by south-west come mainly from Poland (probably 75%), the others coming mainly from Germany and Sweden, and also from Norway (where there are only astonishingly only 10 breeding pairs left) – so almost only from EU countries. The first pages of the report are a summary of overall results, then detailed parts on each techniques. (genetics, isotopes, geolocators). (see links below)

Andrea Rutigilano, an on-the ground warrior for CABS also featured in the film says, “We have won our battle against Ortolan Bunting trapping and the phenomenon is basically wiped out from Les Landes.”

Frédéric JIGUET sent us the links to this comprehensive research study about the Ortolan Bunting.
