There are a lot of beautiful birds you can only see in winter season
Absolutely everyone is aware of that in the slide, lots of acquainted birds migrate to hotter, sunnier sites and usually are not viewed again right up until the spring.
But as it turns out, for lots of northern birds, “warmer, sunnier spots” are not essentially sizzling spots like Florida or Mexico — they’re places in southern Canada like Vancouver, Toronto, Halifax and the southern Prairies.
That indicates winter season is the only time when most Canadians can see Arctic waterfowl like prolonged-tailed ducks (see photograph above) and buffleheads, tundra birds like snow buntings and snowy owls and boreal birds like popular redpolls.
Not only can you see species that continue to be significantly in the North at other situations of the yr, but many of them also congregate in large numbers that make them a lot easier to see, and there are no leaves in the way.
Emily Rondel, president of the Toronto Ornithological Club, suggests quite a few Arctic ducks need open up h2o so they can dive for food stuff, and Lake Ontario is frequently the to start with open up h2o body they locate when they fly south. That suggests 1000’s kind teams or “rafts” on the lake that she phone calls the “winter waterfowl spectacle.”
“It really is definitely, seriously thrilling to see people species since we will not get to see them at other situations a yr,” she claimed. “They have all types of different, wonderful colours and designs and they are all really uniquely stunning … in addition I can rely on them. I know that they are heading to be there each winter season.”
Similarly, in winter, other types of Arctic ducks and shorebirds these kinds of as snow geese and dunlins flock to places like the coasts of B.C. and Nova Scotia.
Meanwhile, Saskatchewan has the maximum wintertime density of snowy owls anyplace in the entire world, says Stan Shadick, who runs well-known snowy owl excursions out of Saskatoon in the winter. His enterprise, Saskatoon Custom made Hen Excursions, also gives a tour to see willow ptarmigan, a different Arctic species that only arrives within just get to of southern Saskatchewan in winter season.
“One particular of the fascinations of hen-viewing is there’s always a little something various to see,” Shadick stated.
Yousif Attia, a biologist with the conservation team Birds Canada, explained simply because several Arctic birds congregate in city spots in winter season, scientists can get assist from the community to keep an eye on them during events like the approaching Good Backyard Chicken Rely, which operates Feb. 17-20.
“We can in fact rely a ton of them all in one place, whereas in the summer time, they’re just far more spread out,” he claimed. Arctic species like prolonged-tailed ducks tend to scatter across largely inaccessible northern lakes, forests and tundra in the course of the breeding year.
Monitoring plans exhibit that numerous birds aren’t wintering as far south as they employed to. “We’re observing more and a lot more winter birds every yr, actually,” Attia claimed. “I would say wintertime is the greatest time to get fascinated in birds.”
Want to try out winter season birding yourself?
Rondel recommends starting by likely out to natural or waterfront parts with an open up mind. She indicates bringing binoculars or a digital camera to get a closer search and creating use of bird identification apps like Merlin. “That helps make birding a lot of enjoyment, for the reason that it will help you figure out what you might be observing.”
If you want to participate in the Great Backyard Chicken Depend, the sightings you file on Merlin or eBird will mechanically be counted involving Feb. 17 and 20.

“I savored Emily Chung’s report on unsightly fruit and veg. Foods insecurity is a substantial issue these days. My plan is that expiry dates on food items are generally beauty as very well as random CYA guesses by the manufacturer. Why do canned foodstuff and jam have this sort of quick expiry dates? Who dreams these up? Canning, jams and preserving by fermentation (cheese and yogurt) were used in the previous to retail store meals long term. There are so lots of preservatives in breakfast cereal, sliced bread and other very processed foodstuff that the short very best in advance of dates are a preposterous squander of food. When is the Canadian Food Inspection Agency going to wake up and deal with this great squander of food. Next thing they’re going to put an expiry day on is salt!”
Lenn Hart:
“My father was several years ahead of his time. In the ’60s, he dealt with huge families who struggled to get food items on the table. So, he acquired day-outdated bread, buns, and so forth. via grocers (they had to crystal clear shelves right after a couple of days and restock with clean). The products was even now good and he marketed it in bulk at a price reduction. Something left soon after a few additional days was bought or provided to the local farmers as feed for their animals. Tiny or no squander.”
David Grigg experienced a reaction to some of last week’s reader feedback suggesting that supermarkets don’t generally update the stickers on their fridges soon after altering refrigerants:
“Terrific data on refrigeration in supermarkets. Re: sticker updating refrigerant gas: so simple to put an update sticker on the door and proclaim environmentally friendly credits. My motor vehicle tire and oil modify shop never fails to update their servicing suitable on the windscreen.”

The Huge Photograph: Rewilding Arts Prize
A great deal of the coverage all over climate improve and biodiversity reduction is quite detrimental, for noticeable motives. But for lots of environmentally engaged individuals, the increasing severity of the problem has opened up a area to believe in different ways about our partnership with the natural globe.
Just one instance of this is the Rewilding Arts Prize, a new initiative recognized by the David Suzuki Foundation and Rewilding magazine that celebrates Canadian artists “who are making use of creative indicates to creatively visualize and bring consideration to troubles of rewilding in our life and communities.” Additional than 550 artists applied, and the jury not long ago declared 6 winners (just about every getting $2,000).
They contain Quebec multidisciplinary artist Khadija Baker (image higher than), whose set up Executing Community Backyard garden includes her donning an outfit manufactured of handmade paper and crops and inviting passersby to acquire a plant, just about every of which is named right after a human being “shed or displaced through violent circumstances of many local communities.”
There’s Toronto-based Amanda McCavour, who makes big-scale embroidery installations with powerful ecological motifs. The get the job done of Vancouver theatre firm The Only Animal emphasizes humanity’s elemental link with mother nature, although Vancouver’s Natasha Lavdovsky finds inventive approaches to transform lichen into artwork.
You will find also Anishinaabe artist Amber Sandy, who, amid other issues, will make baggage out of birch bark, deer and moose disguise as a way to honour common practices that were disturbed by colonialism. And Justin Tyler Tate generates what he calls “Put up-Anthropocene architecture” — improvised buildings in mother nature that increase queries these as: “Which non-human species are its supposed users?”
Sizzling and bothered: Provocative thoughts from all-around the website
- A team of University of Ottawa pupils is working with soaring foods rates by dumpster diving powering supermarkets prior to browsing inside. They describe why and how they do it.
What is a microclimate? And why is it significant?
Microclimates exist all about us. It may be a side of a town that often appears to be a tiny hotter or constantly receives far more snow.
Consider about Calgary, with its rain shadow from the mountains and chinook winds, or downtown Vancouver, which usually is warmer and sees fewer snow than encompassing regions.
Microclimates can range in scale from the city warmth island result that encompasses an total downtown appropriate down to the sides of your lawn that are equipped to increase different points.
When you seem at a microclimate, there are a ton of variables at engage in, but in basic conditions, it arrives down to temperature and dampness.
“A microclimate essentially is the way … the solar energy is used by the surface,” explained Sylvie Leroyer, a investigate scientist with Surroundings and Weather Alter Canada.
Leroyer said that the things primary to a microclimate can be complex, including almost everything from how porous the ground is and how significantly shade an location receives to the sum of reflection off the floor and adjustments in elevation. H2o bodies will also engage in a job by moderating temperature and influencing wind designs.
“For the duration of the working day, you would have wind circulation coming from the water toward the land that is hotter, and in the night it is the reverse,” she explained. “All all those consequences interact alongside one another so that at the end, it can be quite complex.”
Microclimates can have a considerable impact on the plants and animals inside them.
Mhairi McFarlane, director of science and stewardship with the Nature Conservancy of Canada, claims that distinctions in microclimates are often a lot more obvious in mountainous or coastal places. But even in flatter locations, little undulations can build their very own microclimates that enable with species range.
“You can anticipate to see distinct animals and various plants and unique locations due to the fact of these really modest versions in humidity and gentle.”
McFarlane explained wetter, shadier places will host distinct species than higher, dry, sunny spots on the best of a little hill or even a truly slight incline.
And microclimates can evolve, both on their personal or with an exterior disturbance.
“If you have a natural hollow, then drinking water will assemble in there and that signifies that vegetation, for illustration, that have tailored to … obtaining their feet soaked will mature there,” she claimed. “As they increase, areas of them die. They’re going to also fall seeds into the h2o and soil and that will type of alter that microclimate over time.”
Each individual garden will have its individual microclimates, and understanding them is very important to owning a thriving backyard garden, suggests Helen Shook, a investigation technician who operates GardenLine, a free support service available by the College of Saskatchewan.
It begins with the positioning of a property. Shook claimed that commonly the south side will be drier, while the west will get scorching sunlight in the summertime and the north is often shadier and windier.
But which is just the starting. You also have to take into consideration things like slope.
“Lower-lying places are inclined to be parts where by h2o will accumulate but also frost will type of settle and be at the base of a slope,” Shook claimed.
In urban areas, your neighbours will have an impact on your microclimate, too.
“In metropolis properties, we have neighbours with residences, with garages, we have fences, and all of individuals items will gradual wind pace down,” she mentioned. “Taller properties can be a minimal bit of an issue, due to the fact based on how substantial they are, they can truly funnel wind down and generate a pretty turbulent region.”
