Hello Everyone

This past week marks a couple of Monarch firsts for the 2010 season. As many of you know the end of August is the start of the Monarch season. If you’ve come by the Visitor Centre in the past couple of weeks you may have noticed that our Monarch tank has been in full swing with up to 15 caterpillars at one time. I’m happy to say that the first of the chrysalises has successfully hatched into a handsome male Monarch Butterfly. The other first was of course our first tagged butterfly at the park. The butterfly tags arrived this past Wednesday and we wasted no time. Emily Slavik had the honour of the first tag this year, by tagging a male while showing some visitors how and why we tag butterflies.

As much as I enjoy the Monarch season, it does bring a twinge of sadness. Monarch tagging means the summer is coming to a close. The days are noticeably shorter, the summer staff are starting to say their goodbyes and the summer is turning into a fond memory. But summer isn’t the only thing saying goodbye. As August leaves, so must I. I’m taking a leave of absence from Rondeau to go and spend the next 8 months away at Teacher’s College. I’ve had another amazing summer here at the park, met some great people, participated in some great programs and have made many wonderful memories to carry me through until I return next June. I like to say thank you to all the amazing visitors and the awesome staff the made this my best summer here.

But I can’t say goodbye without giving one last creature feature that leaves a lingering impression. And nothing lingers like the sweet, delicate smell of skunk musk. Even their scientific name Mephitis mephitis pays homage to their fragrant nature by translating into “the smell, the smell”. Skunks get the reputation of spraying their stench at the slightest of provocation, but this is simply not true. It takes the skunk energy and time to refill depleted scent glands so the less they spray, the better for them. On top of that, they don’t like the smell any more than we do so they only use this mighty defensive weapon as a last resort.




Striped Skunk


Skunks will give you plenty of warning before spraying. The first thing they will do if you approach too closely is grunt and stomp their feet on the ground. This is skunk-ese for “don’t come any closer”. If you mistake the skunk’s meaning and continue to approach they will turn their body into a U-shape with both their head and rear end pointing at you. This means “GO AWAY NOW!!” Of course, if you don’t follow this blatant body language don’t be surprised if no one wants to come anywhere near you for the next few weeks. The mechanics of the spray are fascinating in their own right. There are two glands that each squirt out a stream of oily, yellow-green fluid. About a foot behind the skunk the two streams collide in mid-air and turn into a nauseating mist. When the skunk sprays, they are typically aiming for the assailant’s eyes. If the mist gets into your eyes it can cause burning blindness for 15-20 minutes, which is more than enough time for the skunk to make an escape.

Don’t fear that your Rondeau Events update is at an end. Laura Penner is graciously taken over as writer in chief. I hope to see you all next summer. Until then, have a fabulous year.

Hello Everyone

It’s sad to think that the summer is coming to an end, but not everything about the end of summer is sad. All I’ve got to say is that the end of summer means BABY TURTLES!! Ryan Bolton, one of the researchers in the park has been incubating turtle eggs all summer and now they’ve started to hatch. Raccoons, skunks and other nest predators take a huge toll on the turtle nests in the park. The odds of an egg making it to adulthood are very low, less than 1%. Ryan’s work helps to give the turtles a better chance by at least getting them to the hatchling stage. Over the course of his work here, he has helped thousands of eggs hatch. But even with all his help, there are still turtle eggs that do it the natural way and hatch in the wild. If you are really lucky you’ll get to see some tiny turtles, the size of a twoonie, making their way across roads and down the beach to the water. So keep a wary eye out as you are driving around and if you see any give them a helping hand on their journey.

But baby turtles aren’t the only reptiles that made the Rondeau headlines this week. We also had a visit from Reptiles at Risk this past weekend. They taught our visitors about the many snakes and turtles that live within Ontario. And to top the whole thing off, everybody who wanted to, was able to hold a snake and discover for themselves what they really feel like. And let me tell you, the staff definitely took advantage of that experience because you don’t often get the chance to hold a Northern Water Snake.

There is another treat at the end of the summer – fall flowers. When most people think about wildflowers it is usually Spring that springs to mind. But there really are some beauties that flower this time of year. One of my favourites is Blazing Star. For me, these plucky little flowers looks like little purple torches that are come hither signs for a lot of our butterfly species. Blazing star has several flowers along a tall flower spike. Unlike many other species with flower spikes, the flowers at the top bloom first and slowly move down the stem. In the middle of their blooming period you can have seeds forming at the top of the stem and flowers blooming at the bottom.

Blazing Star isn’t considered an important food source for mammals like deer, but as far as humans are concerned it has a rich history in medicinal uses. The Native Americans used a tea from the roots to treat dysentery and applied the tea to the outside of their horses before a race, claiming that the treatment increased their speed and endurance. The European settlers used the tea as a diuretic and gargled it to help sore throats. In my opinion, the coolest common name this plant has ever had was Rattlesnake Master for its use as a poultice to treat snakebites.

p.s. Although I didn’t mention it this week, our pond and waterfall in the bird garden are up and fully functional. I’d like to send out a big thank you to S. I. Water Gardens for all their help and donations.

Hello Everyone

I’ve decided to take up moonlighting as a carpenter. One of the unofficial goals here at the Visitor Centre is to create two new displays per summer. That way there is always something new to see and learn even if you visit every year. The first new (redesigned) display for this year is the bird/butterfly garden. I take absolutely no credit for the wonderful work that has been done. Most of the credit goes to Laura, Brady and Lauren, but all the staff have pitched in here and there. The newest addition to the garden is a tranquil waterfall that cascades serenely into the back of the pond. The sound of running water is very attractive to many species of birds and we’ve already had both American Goldfinches and Indigo Buntings bathing in the waterfall.

However, none of that explains my desire to moonlight as a carpenter. The second display we’ve decided to create is a new tracking display. Although there technically is already a tracking display, it was created quickly to see if it would be a popular display. The goal was always to build a special table to house the tracks, sand and interpretive information. Therefore I decided to try my hand at carpentry. With a fair amount of trepidation I went out and bought a bunch of wood and hid myself in the maintenance yard. After expecting to create something that looked a lot like a grade 3 craft project, I was pleasantly surprised with the results. There is still some sanding and painting to be done (aka covering up oopsies), and it’s never going to win a table beauty contest. All in all it’s looking pretty good and I hope to have it ready for the public in a week’s time.

The other noteworthy occasion of the last week was the melodious music of Allison Lickley. The crowd at her concert on Saturday evening were treated to some beautiful original music and even sang along to some good campfire classics like Black Socks and The Other Day. More than one of us was reminded of a young Joni Mitchell as we listened to her sing. A big thank you to Allison for gracing us with her presence, to the Friend of Rondeau for bringing her in here and to the Grace Anglican Church for letting us hold the concert there.

Well I figured with all my ravings about carpentry I should keep the theme going and talk about every carpenter’s need – wood. Not just any wood either, but wood in the form of the highly prized Black Walnut tree. Nowadays, Black Walnut is highly prized for its beautiful grain. But it wasn’t always so, old trees (from the pioneer days) were very straight grained. Most of the Black Walnut back then was forest grown. In the shaded woods, the tree grew much slower and therefore had a denser straighter grain. Today Black Walnut is grown out in the open and it gets a much more varied grain. With the help of some skilled cutting, beautiful grain patterns are exposed that are ideal for woodworking.





Black Walnut

However, my favourite thing about walnut trees is that they partake in chemical warfare. Now you don’t have to worry about tear gas falling from their leaves, but if you are a neighbouring plant beware. Walnuts produce a colourless chemical called hydrojuglone. It is perfectly harmless until it is exposed to the air or oxidizing substances released by encroaching roots of nearby plants. Then it is quickly transformed into juglone. One of the most common effects of juglone is ‘walnut wilt’ where nearby plants will start to turn brown and wilt and eventually die – Black Walnut’s way of saying “go away, this is my space”. But never fear, some plants have found a way to fight back. Asters and goldenrods have joined in the chemical warfare battle by producing chemicals that are toxic to walnut seedlings and thereby ensuring their own continued health.

Hello Everyone

They say that gardening is a relaxing pursuit that lifts the spirit. After watching some of the staff work and toil at renovating our bird garden I’m not so sure it’s relaxing. But relaxing or not, it lifts the spirit to see all the great work they’ve been doing. The garden had become overgrown and some non-native species had invaded, so it was high time for a makeover. It might look a little bare right now with most of the plants removed, but with the bird feeders moved, the fence fixed and new paths added; we are just about ready for the replanting stage. And their work hasn’t deterred the birds one little bit. Just the other day a beautiful Indigo Bunting was seen checking out the new digs.

Not only has this weekend brought in August, it has also heralded in our month of guest speakers. We kicked if off with a fabulous program done by WEEP (Wildlife Education and Environmental Program). Based out of the University of Guelph, WEEP helps to rehabilitate birds of prey. Birds that cannot be released back into the wild become part of their educational program and tour Ontario allowing people to see this fantastic birds up close and personal. Highlights included a Great Horned Owl named Einstein who liked to call at men with beards. She imprinted on a man who had a beard and now thinks she is a bearded man and calls to others of her ‘species’. Also present was Socrates the Turkey Vulture who had an unfortunate run in with a car. Although he broke a wing and couldn’t fly, he and was able to survive on road kill for a few days until he was found. Unfortunately, he lost the wing, but still enjoys the high life of touring around Ontario on one of the presenter’s arms.

But don’t despair if you missed this great program because we’ve jam-packed the rest of the summer with guest speakers. Allison Lickley (musician), Joe Crowley (herpetile atlas of Ontario), Ryan Bolton (turtle researcher) and Andrew Cirtwill (musician) will be joining us over the next 31 days. If that isn’t enough for you, we are also hoping to get Dave Beadle to come back this year and “wow” us with the secret lives of moths. Keep an eye on our upcoming schedule to make sure you don’t miss these awesome events.

Since we just covered special guests that everyone wants to see (I hope), I figured I’d cover the other kind of guests – the one you’d prefer to stay away. And what better example of an annoying guest than the wasps that circles your picnic table. They are a few different types that bother us, but the most famous are probably the Bald-faced Hornets and the Yellowjackets.

Bald-faced Hornet


Yellowjacket



These species of wasps are colonial and build big nests either above or below ground. This in itself is a pretty impressive feat as the nest is built from scratch each year. The only wasps to survive the winter are the pregnant queen. When it warms up enough for her to come out of hibernation she starts looking around for suitable materials to start a new nest. Once she finds some wood she likes she’ll tear it off in strips, chew it up, mix it with her saliva and then spit it back out in the form of paper. She uses that first bit of paper to create a row of cells and she’ll lay a single egg into each one. In about 4-5 weeks those eggs will become worker females who will take over the jobs of building and enlarging the nest, collecting food and caring for the larva. The queen is relegated to an egg laying machine. By the end of the summer, there will be up to 400 wasps in a single nest. As the summer winds down two special types of eggs are laid, unfertilized eggs which will hatch into males and larger fertilized eggs that will hatch into future queens.

Their unwanted guest status comes not when they are out foraging for food for the larva, but when they are out to feed themselves. The larva feed on animal food like caterpillars and flies that they paralyze with their stinger. In the spring and early summer, the adults feed on the same food, but as the summer progresses they feed more and more on nectar and sweet liquids like your can of pop which can lead to those unpleasant interactions we’d prefer to avoid. This switch in diet tends to correspond with the maturing of the males and new queens. Once this happens, the social structure of the nest starts to break down and the worker wasps spend more and more time away from the nest foraging on their own. This is why the wasps seem more numerous as summer draws to a close.

For anyone who has been stung, you’ll know that wasp stings are one of the most painful feelings that come from nature. The reason they feel like your arm is being melted by magma is because wasp venom has a three step process. Step 1, the enzymes break down the cell membranes and let the cell contents leak into your bloodstream. When the cell in question is a nerve cell it tells your brain what is happening by using pain as a communication device. Step 2, a second part of the venom slows down your blood flow which in turn makes the pain last longer. Step 3, a third part of the venom breaks through connective tissue between cells allowing the first part to reach more cells and cause more pain. The whole purpose of this three punch knockout is to convince you (aka nest predators) to leave their larva/babies alone. And surprise, surprise it is a spectacularly effective deterrent for most animals like raccoons, skunks and bears.

Although it is easy to panic and swat at the wasps when they invade our picnics, we are better off (and far less likely to get stung) if we just gently brush them away and then cover any food that they show interest in.


Venomously Yours,
Kip


P.S. This has nothing to do with the wasp, but as I was doing the research I just learned that you can train honey bees to sniff out explosive! How cool is that?!
