Smile-inducing, jaw-dropping nature films that will make you want to get out and explore nature!

Tuesday February 5th, 2019, 7:30 P.M., at the Orangeville Seniors Centre, 26 Bythia St.

Batwoman is coming to Town!

Outdoor adventurer Cylita “Batwoman” Guy of the University of Toronto and Ontario Science Centre will talk about her research on viruses and bats.

November 27, 7:30 pm – 9:00 pm, at our usual meeting place.

Cylita Guy is a PhD Candidate in the Department of Ecology and Evolutionary Biology at the University of Toronto. Her research focuses on bats and their viruses. Using a combination of field and computational approaches she is investigating why bats seem to be good at carrying viruses that they sometimes share with humans, but rarely get sick from themselves.

In her spare time she looks to help others foster their own senses of curiosity and discovery. She works as a Host at the Ontario Science Centre and started a Junior Bat Biologist Program in conjunction with the High Park Nature Centre. You can also read about her hilarious field exploits in the recent general audience book Fieldwork Fail: The Messy Side of Science! In her down time, you’ll find her chasing her next big outdoor adventure.


FoldScope — a functioning origami microscope!

For our final Speakers Night of the season we will be hosting a very unique hands on workshop.
You will get to build and use a  FoldScope, a functioning origami microscope made from paper.
These were developed by Manu Prakash and his associates with intent of making microscopy available to everyone around the world. Here is Prakesh at a TED Talk describing his microscope and how it can revolutionize health care in developing countries. .
FoldScopes have become very popular with professional and amateur scientists and naturalists around the world for exploring the microbiome. The microbiome is a diverse world populated by creatures smaller than the eye can see.
You will be using your FoldScope to look for creatures such as rotifers, nematodes, copepods, vorticella, tardigrades, and other fascinating creatures.
For more info about FoldScopes
Tuesday April 24th at 7:30 P.M. at the Orangeville and District Seniors Centre on 26 Bythia St.
Here are several photos of the folding process of making the FoldScope, as well as one hurried photo of a prepared slide of marine diatoms.  (The prepared slide came with a used microscope I was given in elementary school. The slide is now approaching 70 years old, and is rather faded … I think this view is better than I could see with the cheap microscope back then. Such horrid microscopes are still being sold and bought today …)

Ready to fold the clever ramp (on the right side) used as a focusing mechanism. The left side is the lens stage.

The finished FoldScope, ready for use!

Northern Shrike (by Kevin Tipson)

Comments (by a botanist …)

Of note, the cold weather we’ve been having through much of December meant there was very little open unfrozen water, so the geese and other waterfowl including gulls that cluster around water were mostly absent. Northern visitors (i.e., Dark-eyed Juncos, Snow Buntings and Pine Siskins) were present, but few of the more sporadic irruptives were seen. The most notable of these were the one Northen Shrike, and the one Snowy Owl reported by a non-member south of Orangeville along Highway 10. Crossbills, etc., were not reported. (I suspect the excellent seed and cone production during last summer’s well-watered growing season have kept those birds farther north.)

Approximately three-quarters of the total number of individual birds came from 7 out of the 38 species, mostly from those species that congregate in large flocks in winter often taking advantage of agricultural leftovers, i.e., American Crows, European Starlings, Wild Turkeys.  On the other end, 7 species were represented by only 1 individual bird.

In Area 2, south-east from Caledon, we certainly noticed that over a third of birdfeeders maintained and filled in previous years were inactive. That certainly reduced the number and the diversity of species we saw both in residential areas, and along the rural roads near houses.

Comments from Russ (a birder!)

  • Up Trend:  Highest number of Red-bellied Woodpeckers (20) versus 12 last year which was then the highest count. Red-bellied Woodpeckers were first seen in 2006 (1 bird) and then not seen again until 2010 (2 birds).
  • Down Trend:  House Sparrows at 16. Average the last five years is 30. Average for the first five counts (1987-91) was 441.
  • Not a trend, but, rather surprisingly, we saw record numbers of Juncos, Snow Buntings and Grackles (2).
  • On the Snow Buntings, a large flock was seen in both Areas 4 and 6, which adjoin on Hwy 9. I wonder if it was the same flock (estimated at 340 and 400 birds).

Snow Buntings (by Kevin Tipson)

The Pattern

All of this fits with the pattern reported to Ontario Birds by Josh Vandermuelen, one of the aggregators on that site:
“The unrelenting cold weather that has descended upon even the most southerly reaches of the province has limited the number of lingering bird species being discovered, and as a result the Ontario winter bird list is lower than it has been by this date in previous winters.
“Since my last update on December 14, eight new species have been added to the list, bringing it up to 192. In comparison, last year by this date the winter bird list was 207 species, finishing at 216 species. The new additions since my last update are: Vesper Sparrow (Ottawa, London, Sandbanks), Brewer’s Blackbird (Long Point), Tufted Duck (Mississauga to Toronto), Eastern Meadowlark (multiple locations), Indigo Bunting (Seeley’s Bay), Lincoln’s Sparrow (Toronto), Ovenbird (Toronto) and Rose-breasted Grosbeak (Brantford).
“There are very few remaining expected species. Some of the more likely species to be added to the list over the next two months include Boreal Owl, Fish Crow and Pine Warbler. Other species missing from this winter’s list that are more unusual but still observed most winters include Eared Grebe, Black-headed Gull, California Gull, Slaty-backed Gull, Harris’s Sparrow, Spotted Towhee and Gray-crowned Rosy-Finch.”

Red-bellied Woodpecker (by Kevin Tipson)


All in all, an excellent experience again this year! Important data was gathered and submitted to the Audubon Society. Citizen Science is important! We had good times together. We welcomed new and accomplished members, and welcomed back some great friends whom we’ve not seen much of. I’m sorry to have missed the wonderful potluck and post-count gathering hosted by Kevin and Carol.

Thanks to Ron Jasiuk and Russ Macgillivray for organizing this important UCFNC annual event! (If you wish more complete information, please Contact us!

Christmas Bird Count 2017: Get your binos and warm clothes ready!

UCFNC Christmas Bird Count areas

Across North America naturalists have been participating in Christmas Bird Counts for well over 100 years. One of the first participants was a Toronto birder!

The first UCFN Christmas Bird Count was conducted on 12 Dec 1987. So this is the 30th anniversary. The data gathered by volunteers is used to track changes in populations and ranges of bird species. It’s also a great opportunity to enjoy and become familiar with winter birds. Our bird count area includes Alton, Erin, Inglewood, Orangeville, Mono Mills, and the surrounding areas. The bird count area is divided into six sub-areas each of which is covered by a team.

As well, we welcome the data from others who contribute Feeder Watch data. This event is not only about identifying and counting birds. It’s about sharing our enthusiasms together, both during the actual counting as we drive and walk through our assigned zones, and then afterwards as we gather for an informal potluck dinner and sharing session. Drivers, photographers, recorders, and general naturalists are needed — as well as good birders! (I’m personally fortunate to be linked up with a good birder and a good photographer!) We start in the early morning, and count until a lunch break, getting in and out of cars to more carefully scan significant areas. Some sort of lunch break is arranged within each group. Then, later in the afternoon, we gather to have our potluck sharing session. (For those who want, you are welcome to spend some time Friday evening listening for owls as well!)

Last year, because of our cold weeks earlier in December there was no open water other than in streams and creeks so that waterfowl were all but absent in late 2016. However, this Christmas Bird Could is not about bigger or better numbers — it’s about getting as detailed an inventory each year to build into larger patterns. Let’s see how the numbers from this year turn out!

There are two ways to participate:
1. Area Search
Participants work as a group with an experienced leader. Most searching for birds is conducted by scanning skies, fields and yards by driving along backroads and residential roads. In some areas short sections are covered by foot.
2. Feeder Watch
Participants spend the count day monitoring their feeders, listing species and the greatest number they see at any one time. If your property is outside the count circle your information cannot be included in what we send to Bird Studies Canada, but the club will be interested in what you saw and your sightings will be included in the next club newsletter. Contact us for the form we’re suggesting for gathering data.

Post Count Pot Luck Get Together
Traditionally, count day ends with a pot luck supper for all members regardless whether they were counting or not. It’s a great time to socialize with fellow club members and to share stories about the days’ sightings and adventures. This year we will be gathering December 30th starting between 4:30 and 5:00 P.M. For details, contact us.

If you are interested in participating in the 2016 UCFN CBC do one of the following.
1. Look at the attached CBC area map, identify the area you would like to help with or the
area where your bird feeders are located and via email contact the leader of that particular area to let them know how you would like to help.

Area 1: Ron Jasiuk
Area 2: Mark Whitcombe
Area 3: Linda Lockyear
Area 4: Ron Ritchie
Area 5: Dawn Renfrew
Area 6: Rob Best

2. If you don’t have a preference where you would like to be birding, contact us.

January Nature Movie Festival is changed to January 23rd, 7:30 P.M.

We are taking advantage of a new opportunity for our January meeting: a nature film festival. Check this out and click on the €œFestival Films on Tour.€ We are using mainly short films from Jackson Hole Wild to host an event at the Seniors centre for our members. We’ll provide more details shortly!

Because of renovations at the Seniors’ Centre during the last week of January, we have to move the date away from January 30th to Tuesday, January 23rd at our usual time of 7:30 P.M.

A Glorious Gallimaufry!

Nicola Ross will be speaking to us next Tuesday, November 28th, 7:30 P.M. at the Orangeville Seniors Centre. Nicola will be talking about her latest book Dufferin Hikes: Loops and Lattes. This is the third in her series of local hiking guides, the others being Caledon Hikes, and Halton Hikes.

A number of us have used these books as guides for mostly short half-day hikes. She has cleverly chosen interesting routes that loop back to the starting point — and she caps that off with recommendations of where to have excellent snacks and lunches. I’ve enjoyed the several of her recommended routes that I’ve done. My wife hikes every Wednesday with a group of local women who have nearly completed all of the hikes in Nicola’s first two books, and are now beginning to hike through her Dufferin book. They’re loving the routes she recommends!

Nicola has a fascinating background, including being the editor for one of Ontario’s leading environmental journals. She is a hometown woman, having grown up in this area. She has become part of Caledon’s community landscape. Years spent hiking local trails, wandering down country roads and exploring villages prompted her to start the Caledon Countryside Alliance to help protect the area from urban sprawl. A columnist with In The Hills magazine for almost two decades and the award-winning author of five books including Caledon and Dufferin County, Nicola lends her knowledge of Caledon’s past and present to her familiarity with the trails that crisscross its dramatic landscape.

One of many things that fascinate me about having Nicola speak to us is her ability to combine enthusiasm for and understanding of her home environment with a remarkable ability to take action on her concerns, and then wrap that all in an entrepreneurial flavour as an author. She’s a fine example of how to live her passions. Besides, anyone who can title their blog A glorious gallimaufry of hiking stories, facts, figures and reviews, simply has to be seen and heard!

Nicola will no doubt be bringing copies of her books to sell. I know quite a few people who have or are going to get certain books as presents! …

End of Summer updates

Marvellous stretch of weather, eh?  After such a long lush wet growing season, we’re finally having a true Southern Ontario summer that’s straddling the astronomical boundary between Summer and Fall.

Highlights of my natural history this summer include the amazing diversity and beauty of fungi produced on one old poplar stump right in by backyard! On a twenty-year-old stump that’s only ever had Dryad’s Saddle, Polyporus squamosus, suddenly beginning in the middle of July and continuing to the present, I’ve had a succession of amazing finds, only one of which I’ve ever seen before! The surprises began with the brilliant yellow Creeping Dog-vomit Slime Mold, Fuligo septica — which is the one find I’ve actually had before in my yard. (It’s actually a slime mold, not even related to fungi, but I hope you’ll excuse my sloppy phylogeny …) Then came a large brownish brown-spored gilled fungus that I’ve not been able to identify, along with a small ephemeral pale brown gilled fungus, also unidentified.

Elegant Stinkhorn, Mutinus elegans, with Greenbottle Fly

One morning in late July I noticed something scarlet red appearing around the base of the stump. I was able to immediately recognize it as a Stinkhorn, and then more precisely identify it as Mutinus elegans, Elegant Stinkhorn, on the basis of the crimson tip and the brownish-green slime at the tip. At first, one Stinkhorn would come up, and within two days would collapse, only to be followed by another. Then, as many as six would erupt at once. Two months later, I’m still getting days with three or four fruiting at the same time. The fungus appears first in a white ‘egg’ at the surface of the ground, sometimes taking weeks to slowly break free of the white covering which forms a volva cup at the base of the stalk. In due time, the actual stalk and the crimson tip appear literally overnight — within 10 hours! The stalk is beautifully lacy and reticulate, clearly the result of a quick uptake of water to expand the cells that preform in the ‘egg’. The top of the stack appears with the stinky foetid browny-green slime that smells of a combination of rotting salmon and faeces! In the morning, various flies cover the slime, eating it off within several hours, exposing the brilliant crimson tip. The spores of this basidiomycete fungus are in the slime. Thus the flies spread the spores around as they clamber across other rotting wood. I’ve seen at least six species of flies, ranging from Greenbottles, and Bluebottles, and Cluster flies, to various smallish muscid flies like small House Flies, and even Fruit Flies on the slime. Yet another interesting fact is that Stinkhorns seem to be the first fungi described by Europeans in North America, by the British missionary John Bannister in 1679. (I wonder what he made of the striking phallic shape. Perhaps that’s where one of the alternate names of Devil’s Dipstick comes from …)

There have since been at least two other species of mushroom appeared on this stump, including another small unidentified brown-spored basidiomycete. The largest of the summer’s mushrooms has been the striking large cinnamon-coloured Laughing Cap mushroom, Gymnopilus spectabilis. It’s a beauty in its own right, but is definitely eclipsed by the Elegant Stinkhorn in photographic beauty. I’ve no idea where the ‘laughing’ comes from, other than that to most people, the mushroom is poisonous and perhaps hallucingenic, since some strains contain psylocybin. The Korean name translates to bronze clown mushroom.

It seems to me that all of these mushrooms must specialize in the late-stage decay of dead wood. The most difficult of the lignin components of wood are what remains after the 20 years of decay of this poplar stump. Combined with the extreme wetness of this summer, this particular stump has crumbled to the point where I can crush the remaining wood with my bare hands, sometimes squeezing water out of pieces of it.

Ichneumonid Megarhyssa wasp parasitic on horntail wasps in sugar maple tree

Perhaps the other most exciting observation of the summer is also associated with late stages of rotting wood. Just a week ago, I noticed an ichneumonid wasp laying eggs on a dying maple tree on our neighbour’s property along our fence line. These fascinating beauties are often portrayed in introductory entomology books, but I’ve never seen one alive. I’ve since seen at least five on this one tree! (I will show several videos at our upcoming Members’ Night on Tuesday October 25th.) Briefly, this wasp is almost 15 cm long, from the tip of its slender antennae, to the end of the almost 10 cm long ovipositor and sheath. The body alone of this wasp is 5 cm! Various Megarhyssa species live in our area, all of specializing as parasitoids of another wasp, the Horntail Pigeon Wasp, Tremex columba — which I have seen in years past on our property! The female pictured here took over 30 minutes to probe around with her ovipositor, repeatedly pushing it into the softened white-rotted wood inside the sugar maple to search out the Horntail larvae on which to lay her eggs. The Horntail wasp lays her eggs on dead wood and includes spores from a specific fungus which lives on dead wood. The developing Horntail larvae feed on the fungus. Along comes the ichneumon wasps and lays her eggs on the Horntail. The ichneumon larvae live externally on the parasitized larvae, eating them from the outside but leaving the most critical components of the Horntail alive until the the ichneumon is ready to pupate!

Here’s another sighting from our backyard this summer. Can you guess how these particular shapes were formed?
