Today in Nature: A Painted Turtle


September 25th: This is one of Ontario's eight species of turtles. It is a Midland Painted Turtle. When it gets cold, it will settle down into the bottom of a pond to nestle into the mud. These turtles have a special kind of antifreeze in their blood so that they can stand temperatures as low as -9C. Being below the ice, they are okay as long as the entire pond doesn't freeze solid. The other way of seeing this is that a Canadian turtle spends about half of its life under the ice, just dreaming of days like today when it can hang out in the sunshine....

Today in Nature: Great Egrets and the Audubon Society

September 28th: This is a Great Egret, which has played an important part in the conservation movement. The Audubon Society was created in the late 19th century to protect the Great Egret. Its long head plumes ( only seen during breeding) had become fashionable for ladies' hats, and the bird was on the verge of being hunted to extinction in North America. Efforts to protect the Great Egret led to laws forbidding the shooting of wading birds that migrate, which is one reason we can enjoy their beauty today.

Today in Nature: Deer Food and the Prehistory of Toronto


Acorns on the ground in Toronto's High Park

September 29th: I nearly fell when I walked on these acorns today,  it was like walking on ball bearings. Acorns are inconvenient for us, but deer like their protein for fattening up for winter, and to help males in their head-butting competitions. In the 1780s, just before the city of Toronto ( York) was established, the Mississauga tribe used to travel to the Oak Ridge Moraine to hunt for deer when the acorns dropped in the fall. Skins and smoked deer meat would then come down the Humber River to villages close to Lake Ontario.

Today in Nature: A new Disney monster


September 24th: It is amazing what is walking around us, usually unnoticed. This little monster is about as tall as a grain of rice standing on end. He visited me on a park bench, and is so small, I had no idea how cool looking he was until I looked at the pictures. I haven't a clue what he is, and I would love to know. I bet Disney would love to model a cartoon character after him.

Today in Nature:Why do Snails Climb Trees?


September 23rd: One way of knowing if it has been raining really hard lately is whether there are snails on the trees. Snails don't like drowning, so when a downpour comes, they head for higher ground, even if it means hauling themselves straight up. Fortunately, there's lots to eat, such as mould and dry dead matter on a tree's surface. When the ground is dry, they will head back down, where they come out mostly at night to eat rotting leaves, just doing their part to keep the planet tidy.

Today in Nature: The Fall Equinox

September 22nd: Happy fall equinox, all. The term 'equinox' is Latin for 'equal night', since the ancients noticed that days and nights are roughly equal at this time of year. Here in Ontario, we are losing 2-3 minutes of sunlight each day, as we slide towards the shortest day of the year in December. That loss of sunlight is triggering all sorts of natural changes, including leaves losing their green pigment, revealing their reds, yellows and oranges.

Today in Nature: What Roots Really Look Like


September 18th: Here's a good look at what tree roots look like, thanks to an eroded hill in one the city's ravines. Roots are pretty cool - they weigh about as much as all the branches and leaves, making them an underground mirror. Roots tend to grow outward, like the bottom of a wine glass, providing stability. They usually don't go very deep, either, since their job is seek out and absorb water and minerals. The roots grow in a random way, often along the tracks made by worms or natural grooves in the soil.

Today in Nature: An American Goldfinch

September 19th: It took me a while to figure out who this was - I am pretty sure it is an adult female American Goldfinch. Their male mates are a bright yellow. This one was with a flock that was happily harvesting the seeds from these late flowering plants. Goldfinches rely on seeds, so they breed late in the summer, unlike most other birds. Once the breeding is over and the young are ready to fly, they will head south to the U.S. for the winter. I hope they have health insurance....

Today in Nature: We are all children of the corn

Corn and the sun in Brampton, Ontario. www.torontonature.com
September 20th: I was in the country today to celebrate my Aunt and Uncle's 60th wedding anniversary. When they got married, corn was just starting to become one of North America's big crops. Scientists had figured out how to take this South American plant and change it so that it could endure being crowded together to increase crop yields. Next, they made the kernels infertile, so each year, farmers have to buy new seed. When my Aunt and Uncle got married, corn was something you ate, when you ate, well, corn. Now it is used to make 1/4 of all the stuff you can buy in the supermarket - it is in soda pop, most cereals, processed foods, and even in the plastic packaging. So if we are what we eat, we are all now children of the corn.

Today in Nature: The Tool-Using Heron

A Green Heron in High Park

September 21st: Today was my birthday, and nature gave me a present, by having this wonderful creature fly across my path as I was riding in High Park. Green Herons are the lest common of the herons in Toronto, and are quite small. But they are smart- they are one of the few bird species that have been observed using tools. They sometimes use twigs or bread in the water to lure fish closer.  So, it was a real treat to see this one today. We are surrounded by wonders....

This day in nature: A glorious Great Blue Heron

A beautiful great blue heron in Humber Bay Shores Park, September 17th, 2014

September 17th: This is why they are called Great *Blue* Herons. What gorgeous plumage. This is a mature heron, who will be leaving us in a month or two to fly down south. If you ever see a Great Blue while on holiday is Florida or Cuba, you may be looking at a fellow Torontonian.

This day in nature: Where do Raccoons sleep?

Sleeping Raccoon in High Park, Toronto
September 16th: I spotted this ball of fur high in a tree today. It is a sleeping raccoon, and since it is alone, it is probably a male. Raccoons have matrilineal societies - mothers sleep with their young, as well as their grown daughtersfrom previous breeding years ( and their young). Males, on the other hand, sleep alone once they are adults, and shift spots every few days. So if you have raccoons in your garage, they may be different ones every few days. Raccoons like to move around, even the mothers and their young.

This day in nature: Galling leaves


September 14th: These strange growths are called 'galls', and when I told my wife what they were, she said they made human sex seem clean, neat and tidy. Here's why: bugs like aphids bite the bottom of the leaf, secreting special chemicals. The leaf reacts by growing the gall, which is like a defence mechanism. What it doesn't realize is that the bug lays eggs within the gall, which serves as the new home for the young ones as they hatch and eat. When the gall turns red, it is ready to burst open, Alien-like, to release the juvenile insects into the world. The good news is that the plant survives all of this just fine. On the up side, it does make human reproduction seem downright neat.

Today in Nature: Tracking Monarch Butterfly Migrations

A tagged monarch butterfly seen in Toronto, Canada.

September 10th: So here is how scientists track the migrations of monarch butterflies. I came across this one in High Park today. The tag is from the University of Kansas, which invites people in North America to affix these tags to the butterflies so their routes can be tracked. I have emailed them with the information, and hopefully they will let us know where this butterfly has been. It is possible it was tagged here. However, it is the right time of year for it to head south for Mexico. If so, this may be one of its last days in our fair city before making its amazing journey southwards. I'll let you know if the University gets back to me about where it was tagged. Cool, eh?

Today in Nature: The Harvest Moon


September 9th: If you look out the window over the next few nights, you'll spot a Harvest Moon. Due to the closeness to the fall equinox on September 23rd, it will seem like we have several nights of bright full moons. The Harvest Moon usually occurs within two weeks before or after the equinox. This year, it is before, which means that while the nights are still reasonably warm you can get a chance to check it out.

This year the moon will even look a little bigger than usual, due to its current position and rotation, making it what astronomers call a Super Moon. But ultimately, it is really just pretty, a beacon in the last nights before fall officially begins.

This day in Nature: Heavenly Grass

Chinese silver grass in Mimico Creek, Toronto

September 8th: This heavenly-looking grass is Chinese Silvergrass. The silver head is beautiful, and full of seeds. Thousands of seeds will be lofted into the air by this stand of plants alone, which may explain how this grass got here. It is an ornamental grass that probably escaped from someone's garden on the wind, and now grows in the sheltered valley of Mimico Creek, far from any house.

How many creatures are in this picture?


September 5th: In honour of this being the first week of school, a picture to share with the kids: how many creatures do you see in this picture, and what are they? Hint: all of them have appeared in the Nature Diary this summer. All answers welcome. Thanks to High Park and serendipity for the image.

Today in Nature: Mating Monarch Butterflies

Mating Monarch Butterflies
Mating Monarch Butterflies
September 3rd: Birds do it, bees do it, and this is how monarch butterflies do it. The male has his wings outstretched. The thin black dot near the bottom of his wing contains a scent which has attracted this female. The fact that this pair is mating means they won't be flying south this fall. Their offspring will do that, being born without active sex organs, so they will have the strength to head to Mexico. If they get there, next spring, they will breed, with newly matured sexual organs. Their parents, seen here, have a lifespan of just 3-5 weeks as butterflies. Their great-great-grandparents arrived in Toronto this past spring. Die young, stay pretty?

This Day in Nature: We have even changed the weeds at the side of the road

Common Reed, Phragmite Australis, along the 401 highway in Ontario
September 2nd: I spent much of yesterday and today on the 401, driving my son to Montreal for school. Along the way, practically every roadside ditch was thick with this plant, known as Phragmite Australis. I wondered why there was so much of it. Turns out, it is an invasive species from Europe that likes brackish ( i.e., salty) water. Scientists suspect that the reason it is so common beside highways is that the salt from the roads keeps the ditch water brackish, an environment this plant loves. Everything really does affect everything else, in ways we can barely fathom....

This Day in Nature: The American Dagger Moth

American dagger moth caterpillar

September 1st: This living, breathing stuffed animal is the caterpillar form of the American dagger moth. It's not much to look at as a moth, butcheck out those black daggers coming out of the Telly Tubby yellow coat! In October this little guy will find a place to create a cocoon, then spend the winter laying low, transforming. In the spring it will fly away as a brown moth.
