There are lots of stunning birds you can only see in wintertime
Everybody is familiar with that in the drop, many familiar birds migrate to warmer, sunnier spots and usually are not witnessed again till the spring.
But as it turns out, for many northern birds, “hotter, sunnier spots” aren’t essentially warm spots like Florida or Mexico — they are spots 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 extended-tailed ducks (see photo earlier mentioned) and buffleheads, tundra birds like snow buntings and snowy owls and boreal birds like frequent redpolls.
Not only can you see species that continue to be significantly in the North at other periods of the year, but quite a few of them also congregate in large numbers that make them simpler to see, and there are no leaves in the way.
Emily Rondel, president of the Toronto Ornithological Club, claims numerous Arctic ducks have to have open h2o so they can dive for food, and Lake Ontario is often the 1st open water physique they discover when they fly south. That usually means 1000’s form groups or “rafts” on the lake that she calls the “winter waterfowl spectacle.”
“It can be actually, actually enjoyable to see those people species since we don’t get to see them at other instances a 12 months,” she mentioned. “They have all kinds of unique, amazing colours and designs and they’re all definitely uniquely beautiful … in addition I can depend on them. I know that they are heading to be there each winter.”
In the meantime, Saskatchewan has the best winter season density of snowy owls any where in the entire world, states Stan Shadick, who operates well known snowy owl excursions out of Saskatoon in the wintertime. His firm, Saskatoon Customized Hen Tours, also offers a tour to see willow ptarmigan, a further Arctic species that only will come within just get to of southern Saskatchewan in winter season.
“A person of the fascinations of chook-watching is there is usually something distinctive to see,” Shadick explained.
Yousif Attia, a biologist with the conservation group Birds Canada, explained for the reason that many Arctic birds congregate in urban locations in wintertime, scientists can get help from the general public to keep an eye on them all through events like the impending Wonderful Yard Fowl Rely, which runs Feb. 17-20.
“We can in fact count a good deal of them all in 1 spot, whilst in the summertime, they’re just much more unfold out,” he reported. Arctic species like very long-tailed ducks are likely to scatter across mainly inaccessible northern lakes, forests and tundra throughout the breeding time.
Checking courses display that lots of birds are not wintering as considerably south as they utilised to. “We’re viewing extra and much more winter season birds each individual 12 months, seriously,” Attia explained. “I would say wintertime is the ideal time to get interested in birds.”
Want to test winter birding on your own?
Rondel recommends beginning by heading out to purely natural or waterfront regions with an open mind. She suggests bringing binoculars or a digicam to get a nearer search and earning use of bird identification applications like Merlin. “That would make birding a large amount of entertaining, simply because it can help you determine out what you’re looking at.”
If you want to participate in the Excellent Yard Chicken Count, the sightings you document on Merlin or eBird will mechanically be counted between Feb. 17 and 20.

“I savored Emily Chung’s report on unpleasant fruit and veg. Food stuff insecurity is a huge issue these times. My plan is that expiry dates on food stuff are often beauty as properly as random CYA guesses by the company. Why do canned meals and jam have these types of brief expiry dates? Who goals these up? Canning, jams and preserving by fermentation (cheese and yogurt) had been applied in the earlier to shop foods long term. There are so quite a few preservatives in breakfast cereal, sliced bread and other highly processed foodstuff that the shorter most effective prior to dates are a preposterous squander of food stuff. When is the Canadian Foodstuff Inspection Company likely to wake up and tackle this tremendous squander of food stuff. Next thing they’ll place an expiry day on is salt!”
“My father was years ahead of his time. In the ’60s, he dealt with big families who struggled to get food items on the table. So, he purchased working day-previous bread, buns, etc. by grocers (they experienced to clear shelves immediately after a number of days and restock with contemporary). The solution was continue to great and he offered it in bulk at a discounted. Everything remaining just after a handful of much more days was marketed or offered to the nearby farmers as feed for their animals. Minimal or no waste.”
David Grigg experienced a reaction to some of very last week’s reader opinions suggesting that supermarkets do not always update the stickers on their fridges soon after shifting refrigerants:
“Great information and facts on refrigeration in supermarkets. Re: sticker updating refrigerant gas: so uncomplicated to put an update sticker on the doorway and proclaim green credits. My car or truck tire and oil transform store never fails to update their servicing right on the windscreen.”

The Massive Picture: Rewilding Arts Prize
A large amount of the protection around local weather transform and biodiversity decline is very adverse, for noticeable factors. But for quite a few environmentally engaged individuals, the rising severity of the difficulty has opened up a place to imagine in a different way about our marriage with the natural environment.
One particular example of this is the Rewilding Arts Prize, a new initiative established by the David Suzuki Foundation and Rewilding journal that celebrates Canadian artists “who are utilizing creative implies to creatively visualize and deliver awareness to problems of rewilding in our lives and communities.” Much more than 550 artists utilized, and the jury lately announced six winners (every acquiring $2,000).
They involve Quebec multidisciplinary artist Khadija Baker (photo above), whose set up Accomplishing Group Backyard garden will involve her donning an outfit produced of handmade paper and crops and inviting passersby to just take a plant, each of which is named right after a person “misplaced or displaced by means of violent circumstances of various regional communities.”
You will find Toronto-based Amanda McCavour, who makes significant-scale embroidery installations with powerful ecological motifs. The get the job done of Vancouver theatre enterprise The Only Animal emphasizes humanity’s elemental link with nature, although Vancouver’s Natasha Lavdovsky finds inventive ways to turn lichen into artwork.
There’s also Anishinaabe artist Amber Sandy, who, between other points, makes bags out of birch bark, deer and moose hide as a way to honour classic procedures that were being disturbed by colonialism. And Justin Tyler Tate generates what he phone calls “Post-Anthropocene architecture” — improvised buildings in nature that increase queries this sort of as: “Which non-human species are its meant buyers?”

What is a microclimate? And why is it vital?
Microclimates exist all close to us. It could be a side of a city that often seems to be a minimal warmer or normally gets more snow.
Consider about Calgary, with its rain shadow from the mountains and chinook winds, or downtown Vancouver, which commonly is warmer and sees considerably less snow than encompassing regions.
Microclimates can range in scale from the city heat island effect that encompasses an complete downtown right down to the sides of your property that are capable to expand various items.
When you seem at a microclimate, there are a lot of aspects at perform, but in straightforward conditions, it comes down to temperature and dampness.
“A microclimate basically is the way … the photo voltaic strength is applied by the floor,” claimed Sylvie Leroyer, a investigate scientist with Natural environment and Local weather Improve Canada.
Leroyer reported that the elements main to a microclimate can be complicated, which includes all the things from how porous the ground is and how considerably shade an space will get to the sum of reflection off the ground and variations in elevation. Water bodies will also engage in a function by moderating temperature and impacting wind styles.
“For the duration of the working day, you would have wind circulation coming from the water towards the land that is hotter, and in the evening it truly is the reverse,” she said. “All all those effects interact collectively so that at the stop, it can be rather elaborate.”
Microclimates can have a substantial effect on the vegetation and animals inside of them.
Mhairi McFarlane, director of science and stewardship with the Character Conservancy of Canada, claims that variances in microclimates are generally a lot more obvious in mountainous or coastal parts. But even in flatter places, compact undulations can make their own microclimates that support with species range.
“You can assume to see distinctive animals and unique vegetation and distinctive places since of these incredibly small versions in moisture and light-weight.”
McFarlane claimed wetter, shadier places will host various species than high, dry, sunny places on the leading of a tiny hill or even a definitely slight incline.
And microclimates can evolve, either on their individual or with an outdoors disturbance.
“If you have a natural hollow, then h2o will collect in there and that means that vegetation, for instance, that have adapted to … having their feet damp will increase there,” she mentioned. “As they improve, sections of them die. They’ll also drop seeds into the h2o and soil and that will variety of transform that microclimate in excess of time.”
Just about every yard will have its have microclimates, and understanding them is crucial to acquiring a thriving garden, suggests Helen Shook, a investigate technician who operates GardenLine, a cost-free enable support offered by the University of Saskatchewan.
It starts with the positioning of a yard. Shook said that typically the south facet will be drier, though the west will get warm sunlight in the summer season and the north is often shadier and windier.
But which is just the beginning. You also have to take into account points like slope.
“Very low-lying parts have a tendency to be regions where by h2o will accumulate but also frost will type of settle and be at the bottom of a slope,” Shook claimed.
In city places, your neighbours will have an affect on your microclimate, too.
“In town attributes, we have neighbours with homes, with garages, we have fences, and all of those people points will gradual wind speed down,” she stated. “Taller properties can be a minor bit of an problem, for the reason that based on how significant they are, they can truly funnel wind down and create a extremely turbulent area.”
