The Bruce Birding Club had a strong turnout of birders and birds on April 1. James Turland reports: Fred and Marilyn scouted the route the day before in mild, foggy conditions, but we woke to below-zero temperatures on hike day. Oh well—we are a hardy bunch. We visited some favourite spots in search of migrating waterfowl and early arrivals. One particular Pied-billed Grebe gave us great views, paddling alongside Ring-necked Ducks at Browns Pond.  At Baie du Dor, strong winds limited our ability to thoroughly check the gulls. On the way home along Bruce Road 20, there were great views of  Tundra Swans.

April 19 – 26 is Volunteer Week and I have learned that these volunteers at Ontario Nature – ‘Lynn Miller, M.K. Malik, Ted Higginbotham, Ron Corkum, Mao Shiba and Jesica Sobers – collaborated with ON Nature’s Editor John Hassell and Communications Technician Noah Cole, to source, scan and format more than 360?back?issues?of Ontario Nature’s periodicals with content spanning from present day to 1932.’
What a discovery for me, to learn that newsletters of the Federation of Ontario Naturalists (F.O.N. – now Ontario Nature)  have also been digitized and are available for viewing. It was quite a treat to see newsletters from the early 1950s with the distinctive artwork of Thoreau MacDonald on the title page.

To close, a poem by an 11 year old Keith Conover, a member of the Toronto Junior Field-Naturalists Club, in October 1950, entitled:           

‘Conservation’

We need our forests for water and wood
For rayon and syrup and other things good.
We need our grassland so we can keep
Good soil and cattle and flocks of sheep.
We need our swamps for they are able
To keep wildlife  and a high water table.
So you can help by planting trees
And leaving swamps like little seas.
And wildlife should be able to thrive
Cause they’re worth more when they’re alive.

The Owen Sound Field Naturalists (OSFN) will be offering up a bumper crop of exciting presentations for Members’ Night 2026, as coordinated by OSFN’s Brian Robin.

Pearl Bumstead shared this report about  ‘Who Made Those Tracks and Why?’ a recent OSFN Tracking Tutorial February 21, with Jeff Kinchen.

Pearl Bumstead shared this report:

“A small group set out on a trek in search of tracks and Jeff led us to plenty.

The day was overcast with a bit of snow in the air, but evidence of a lot of wildlife was present: Skunk, deer, rabbit, and fisher, just to name a few.

Jeff was very knowledgeable, filling us in about the habits and nature of various species that live in the woods on family property near the Bognor Marsh, on Conc 4.

At the end of our trek, Pam Kinchen treated us all to some yummy goodies & hot tea. Thanks so much to Jeff and Pam, and to John Dickson for organizing yet another fabulous outing.”

These past few weeks have been terrific for me to be active outside, mainly skiing on area trails, and within forests on top of the firm snow, as well as beside frozen shorelines.  The sunshine has been a bonus, with high pressure and clear skies for many days in the past four to six weeks.   However, the recent milder Springlike weather has lured

The Owen Sound Field Naturalists (OSFN)  invite you to learn about the Soils of Grey and Bruce, with David Morris.bWhy do we have so many different types of soil? How were they formed? What makes one soil different from another? How do those factors affect the way they are managed? What makes for a “healthy” soil?

 David Morris’ long career included his work with OMAFRA where he also shared his expertise in nutrient management and soil fertility. In addition he was knowledgeable about field crop and corn production practices, and was a prolific author of many reports and  factsheets plus articles in the Ontario Corn Producer Magazine. In his own words “As a Soils and Crops Specialist, my primary function was to advise farmers on matters related to crop production and soil management practices.”

Morris has also been a key member of OSFN’s publication committee and has led many helpful botany themed hikes too.

This event is scheduled for 7pm Thursday February 12 at the Harry Lumley Bayshore Community Centre, with the doors open by 6:30.
 Everyone is welcome, with Admission by Donation and free for OSFN members.  To learn more please visit https://owensoundfieldnaturalists.ca/event/an-introduction-to-the-soils-of-grey-and-bruce-w-david-morris/

Norah Toth reports: The Owen Sound Group of the Bruce Birding Club did a half day tour of bird feeders and Harrison Park on Wednesday, February 4. It was a cold start to the day but the eight of us had a great morning. A Bald Eagle perched in a tree near the Bayshore Community Centre was our first sighting for the morning. This adult eagle looked like a sentinel guarding the mouth of the Sydenham River.

Our first feeder stop was near the Bognor Marsh where over 60 Evening Grosbeaks looked like yellow decorations in the crowns of the trees covered with hoar frost. What a sight! This feeder was busy. Hairy, Downy and Red-bellied woodpeckers, American Goldfinch, White-breasted Nuthatch, Black-capped Chickadee were in abundance and at times they were joined by a lone Dark-eyed Junco.

Our next stop closer to town added a Cooper’s Hawk, Mourning Doves and just after we left, a Red-tailed Hawk. This feeder may currently be a birds of prey lunch spot.

Then to Harrison Park for some ducks. We were not disappointed. With the Sound frozen over, several hundred Mallards had found what little open water they could. They were joined by Canada Geese and Black Ducks; and by three hybrid ducks. The Goldeneye X Hooded Merganser was very distinctive with a completely dark head shaped like a “hoodie” and the very distinctive colouration of a Goldeneye, minus the white cheek patch. Its golden eye sparkled in the sunlight. This duck has been sighted around Owen Sound in the winter for at least two years. It was great to have a photographer along as the other two hybrids may need a bit more assistance to tie down exactly which species their parents had been.

Our final stop was in town where, among a flurry of other species, sat a Carolina Wren. Typically a fairly secretive species found further south, it appeared quite content with the feeder offerings it has been receiving this winter.

Thank you to the people who allowed us to visit their feeders, it was greatly appreciated. Our morning ended with 22 species and 3 hybrids which for a frosty morning in February was quite satisfying.

I had some good bird sightings myself recently while skiing in the Owen Sound area. These included a Great Horned Owl, in a wooded area which just might also be a nesting area at this time of year. The next day I was skiing on the woodland trails at Hibou and encountered a Pileated Woodpecker and also a Hairy Woodpecker, both of which are always a treat to see.

This coming weekend is also the opportunity to participate  in the annual Great Backyard Bird Count    More details are available at this link – https://www.birdcount.org/

Another Agriculture highlight this month is the retirement from Markdale’s Grey Ag Services of Lorie Smith, a former recipient of the Tommy Cooper Award, and for me, the person to call to learn who might be a good fit for a talk or a field trip with a combined Nature and Agriculture theme for OSFN. Lorie Smith was always helpful, supportive and pleasant to interact with too. Congratulations Lorie! 

More accolades here for Lorie come from a former co-worker who told me – “Lorie has been a great person to work with  during the past 20 years. She has done an excellent job at GreyAg. I am so happy to witness the progress that Lorie and the team has achieved and truly proud of the job that Lorie has done at mentoring the current staff that will lead the team and continue the great reputation the Ag Centre has always been recognized for serving the Agricultural Community not only in Grey County but far beyond our boundaries.

Respectfully submitted!!,

Ray Robertson”

Thank You to Marsha Courtney for sharing this Young Naturalists report, and her photos too.

The Young Naturalist group had a fun outing, snowshoeing the trails at our the Eriksens’ property. . Amanda made the bannock and hot chocolate and we enjoyed a nice fire. We also had some cookies and marshmallows available and tracking ‘ hand-outs.’ We only saw bunny tracks and their dogs tracks. I hope everyone enjoyed it as much as I did.

Walter Muma
Many in the Naturalist community were saddened recently to learn that renowned botanist Walter Muma had passed away unexpectedly on January 8, after a brief illness, at the age of 69.

OSFN’s Willy Waterton and Audrey Armstrong shared this tribute to Walter:

” Hi John,
 So shocking to hear of Walter’s passing. Very sad.  He didn’t suffer fools lightly, but  once he knew you were trust-worthy with not sharing locations of rare plants, he went overboard to help us.
Willy”

“Without Walter, the three publications of the OSFN Publications Committee, Orchids Bruce & Grey, Ferns Bruce & Grey and Asters, Goldenrods, Fleabanes Bruce & Grey would not be complete. He helped us so much in the field, finding the rare species for Willy to photograph.
 Audrey Armstrong”

OSFN’s Brian Maher:
So sorry to hear Walter is gone. He was one of the most knowledgeable botanists I’ve ever met. RIP

I too will miss Walter, and share here, in his own words, his delight after one of his recent summertime birthdays –  “Well I had a very nice day out and about on my birthday. I spent the day hiking and botanizing at an undisclosed location. Came upon an orchid I haven’t seen for many years – Dwarf Rattlesnake Plantain. Of course, it is easily overlooked due to its diminutive size. Also the Cardinal Flowers were out in their fullest glory.”

Here are some excerpts from recent Christmas Bird Counts (CBCs) in the area, as organized by regional ‘Compilers’ who have kindly shared some of their CBC count reports with me. A sampling of their observations follows here: Owen Sound CBC: 

On December 14th, 41 participants tallied 6,425 individual birds of 57 species. Unusual species from this year’s count included a Ring-necked Duck, a Carolina Wren, and several Red-winged and Rusty Blackbirds. Many species were seen in lower numbers this year compared to usual. Surprisingly, however, even more species were seen in higher numbers thanusual, including Redhead, Greater Scaup, Horned Grebe, Bald Eagle (which set a new record for the count this year), American Tree
Sparrow, Dark-eyed Junco, and several species of finches. The irruption of certain northern species of finches we’ve been seeing this
winter are likely due to food shortages in the north.

The 15th Neyaashiinigmiing CBC was also held December 14, with inclement weather as well as illness resulting in several last-minute cancellations, and only 10 participants ultimately covering the circle. Results: a record low species total of 31, well below the average of 40. The 710 individual birds counted was also a record low, and well below the average of 1,062.

 Notable misses included Common Merganser, Ruffed Grouse (first ever miss), Rock Pigeon and Mourning Dove, and Golden-crowned Kinglet (first ever miss.

Despite their presence elsewhere on the Saugeen Peninsula this winter, no winter finches were recorded.  American Goldfinches were present in average numbers.

Jarmo Jalava and Miptoon (Anthony Chegahno), compilers.

The 52nd Wiarton CBC was held December 21, with 24 participants and one feeder watcher tallying 53 species.  The total of 3,917 individual birds was above the overall average of 3,767, but well below the recent ten-year average of 4,983 and less than half the record total of 8,628 set in 2023.

Only one record high species total was recorded: Dark-eyed Junco (105, previously 102).  

Other good finds included a Gadwall, an Iceland Gull, a Golden Eagle, a Merlin, White-winged Crossbill and a Common Grackle.

Winter finches were limited to White-winged Crossbill (2), Redpoll (43), Pine Grosbeak (23) and Evening Grosbeak (113).  As noted, American Goldfinches were present in above average numbers (351). The small House Finch population persists in Wiarton, with a relatively high tally of 16 individuals this year. 

Jarmo Jalava, Compiler.

---

The 55th Meaford CBC on December 28th and the combined efforts of 6 teams and 5 feeder-watchers resulted in finding 50 species. No new species were added to the all-time cumulative total for this count leaving that number at 129 species.  One new ‘High’ came in, for Horned Grebe with an amazing 72 counted, topping the 52 seen in 2023. In the ‘Unusual’ category, a Yellow-bellied Sapsucker (YBSA) was videoed at a valley property. YBSA has not been recorded on the Count since 1973! A Gray Catbird was photographed at the same property the day before the Count, making it only the second record. Total birds were on the low-average side at 3745 birds, with this number bolstered by approximately 500 over-wintering Canada Geese.  Thanks so very much to everyone, and the best for 2026 to all!

I am looking forward to my next visit to the  Owen Sound and North Grey Union Public Library (OSNGUPL) which supplies me with most of my closing Nature quotes (see below) and which is currently featuring the photography collection of AJ Lawrence, a local photographer inspired by the quiet beauty of local landscapes and public places, and the subtle stories of the natural world.

Living with PTSD, ASD, and Auditory Processing Disorder has shaped AJ’s perspective, strengthened his resilience, and enhanced his ability to work independently–qualities he brings to every photographic project.
AJ’s photography will be on display on display until January 31.

In closing, and as one who first had the pleasure of hiking a section of the Bruce Trail in August of 1970, (from Walters Falls to Inglis Falls), I would like to acknowledge here, the passing of Dr. Philip Gosling, who was the last co-founder of the Bruce Trail Conservancy, when he passed away on December 3, at the age of 97. His conservation leadership earned him several honours, including the Order of Canada and an honorary degree from the University of Guelph. Gosling’s tremendous legacy is also celebrated in these evocative words: By the “…sparkling white cliffs and blue vastness of Georgian Bay we hikers enjoy this, the most spectacular stretch of the Bruce Trail… When we trek back from the bay, we silently thank the hikers and conservation groups who fought  for the Bruce Trail, making it possible to follow this great escarpment from Queenston to Tobermory.”  from The Heart of the Country, (which I borrowed recently from our wonderful library OSNGUPL), written in 1988 by Fred Dahms (also now in his 90s), Professor Emeritus, founding member and former Chair of the Department of Geography, University of Guelph, and Illustrated by his wife Ruth.

Bruce Peninsula Bird Observatory

Posted by Station Scientist Stéphane Menu, October 31, 2025 (Excerpt) “The last week of monitoring offered us many treats, as well as reasonably good weather.  On the last four days, Pine Grosbeaks were detected every day, with a few small flocks (6 or 7 birds) on the 29th and 30th. One Pine Grosbeak was captured and banded on the 28th and a second one on the very last day, the 31st! Both were adult females. It is only the sixth fall season with banding for this species.  This species is a rare visitor from the Boreal Forest and an even more rare privilege to have in-the-hand (they are very soft and fluffy!).

Evening Grosbeaks were also detected almost every day during the final week, with an astonishing group of 55 birds on the morning of the 28th! I have never seen such a big flock. [Of warblers] the treat was a Nashville Warbler captured on the 29th! It is the latest record (both for banding and detection) for this species, with one bird seen on the 28th in 2004.And then, it was the last day, as all things eventually come to an end. The final treat was on the final net check, when we extracted a Redpoll: what a nice little bird! This species has been banded in only six previous fall seasons (one to six birds per season), the last one in 2021.It has been another wonderful bird migration monitoring season at Cabot Head for yours truly. I am so grateful to spend my spring and fall seasons here. But nothing would be possible without the help of the wonderful volunteers who give their time and enthusiasm so generously. Like the birds, they are more treats than tricks.”

Amanda Eriksen reported that the Young Naturalists met in Harrison Park October 26, to learn about aquatic invertebrates, fungi, and other species that inhabit the river area there. 

Special guest Naturalist Elaine van den Kieboom led in explaining what to look for in the water as well as under the microscopes they had set up. In addition to the ‘young humans’ in attendance, a juvenile Turkey Vulture also watched the proceedings – from across the river. Young Naturalists had a great meeting on Sunday. Thanks to Elaine from GSCA for sharing her knowledge!

The proposed upcoming schedule for the Young Naturalists looks very inviting – with future experiences that include hikes, snowshoeing, nature art, astronomy, ferns and more. To learn more please visit https://owensoundfieldnaturalists.ca/young-naturalists/young-naturalist-program/

I always enjoy November, as it generally offers some wonderful colour transitions, in particular those of tamarack trees which really put on a show before dropping their ‘golden needles.’  In addition, I especially enjoy the lovely Paper (white) Birch trees whose trunks can gleam in the sunshine while their leaves of golden yellow are backed up by a blue sky.  Much smaller  are the Wild Asparagus plants I have discovered, with their delicate and feathery golden tresses, sometimes with bright red berries.

Recent bird sightings of note, with OSFN last weekend, included a ‘drift’ of Snow Buntings, swirling near the shoreline some distance away. We had a pleasant surprise however, when we had shifted ourselves from Leith to Hibou, and the snow buntings also ‘drifted’ there, foraging amongst the shoreline rocks and giving us excellent views of these visually striking visitors.  During the afternoon, our luck continued, with Redpolls being seen in two locations – atop  a Paper Birch tree, and at another spot, in low shrubs by the shore of the bay. To top it off,  a mature Bald Eagle flew overhead for us to admire too. November also reveals bird nests that were previously hidden from view. Enjoy!

To close, a quote from Beyond the Trees, by Adam Shoalts: “I needed to do some serious thinking. Whenever I was confronted with some momentous decision, I preferred to go where my mind was clearest – to the place I knew best, where I’d grown up, the woods of my childhood… I felt sure I’d know what to do.”

The Owen Sound Field Naturalists (OSFN) are pleased to welcome to an Owen Sound audience on October 9, renowned Wildlife Biologist Dr. Martyn Obbard with his presentation about the Black Bear population of the Saugeen Bruce Peninsula.

A dedicated Research Scientist, Martyn Obbard will discuss the ecology and behaviour of the small, at risk, genetically isolated and unique population of black bears on the Saugeen Bruce Peninsula and how these bears differ from bears elsewhere in Ontario. The presentation will draw on results of a long-term research study conducted jointly by the Ontario Ministry of Natural Resources, Parks Canada and graduate students from Trent University in Peterborough.

Dr. Martyn Obbard is an Emeritus Research Scientist with the Ontario Ministry of Natural Resources, and adjunct professor in the Environmental and Life Sciences Graduate Program at Trent University.

During his long career as a wildlife biologist Dr. Obbard has engaged with many different species and programmes: “As an undergraduate student, I worked on research projects studying Canada Geese and Snow Geese, and Northern Cardinals. My graduate work was on snapping turtles. In my career with OMNR I studied both black bears and polar bears.  As an adjunct at Trent University, I didn’t do any undergraduate teaching but mentored several graduate students, including several who were part of the Saugeen/Bruce Peninsula black bear project.”
This event is scheduled for 7pm Thursday October 9, at the Harry Lumley Bayshore Community Centre. This event is also open to the general public, with admission by donation. It is also to be shared on zoom – with a link to be found at https://owensoundfieldnaturalists.ca/event/black-bears-of-the-saugeen-bruce-peninsula-w-martyn-obbard/

The doors will be open by 6:30pm for meeting friends, membership purchases, and to check out the many items for purchase – clothing, and award winning publications too, etc.

Kudos to Mike Campbell and his team, supporters and cyclists at the Bruce Peninsula Biosphere for staging the 7th Annual Gravel Gran Fondo  on Sunday October 5.  A cycling event from Lighthouse to Lighthouse (from Lion’s Head to Cabot Head), this very successful event is in support of their cause  – Protecting the Bruce Peninsula Biosphere. All funds raised by the Fondo will go to the Bruce Peninsula Biosphere Association (a charitable non-profit organization) to undertake environmental projects on the Bruce. Check out www.bpba.ca for more information. 

Coincidentally, Just this morning I was speaking to someone who cycled it last year, and had a memorable sighting, observing a healthy young Black Bear stretched out on a limb of an apple tree, enjoying a feed of apples from a former orchard along one section of the route, while cyclists pedalled by. The weather also cooperated for a great ride and a wonderful experience too. Bravo!

Young Naturalists report from Amanda Eriksen:

On September 28, the Young Naturalists had a beautiful day to clean out the bird boxes. There were no signs of  bluebirds but someone “laid” some acorns. We did check out the salmon in the river as well, but I was too busy keeping kids dry to take photos! Seems like there are a lot of fish this year!” The club, aimed at ages 7 to 12 (with some leeway), generally meet from 2 to 4pm on the last Sunday of the month, from September to June, with some adjustments for holidays, etc.

Bruce Peninsula Bird Observatory An excerpt from this weeks’ blog 
Posted by Stéphane Menu, September 26, 2025

The past week, September 20-26, marked a radical change from all the previous weeks of this fall season: there were very, very, very few birds captured in our nets. So few that the week total is actually the lowest ever in 24 fall seasons for the week, with only 63 birds banded, five less than the previous lowest totals (in 2017 and 2018). It is such a contrast from the week before (September 13-19), when the banding total came within a few feathers of breaking the record for that week (249 birds in 2024, 246 in 2025!): the higher the climb, the harder they fall!

To close, a quote from The Book of Hope, by the  esteemed primatologist and conservationist Jane Goodall.  Goodall died on October 1, aged 91, while continuing to tour with her important messages, 

including slowing the growth of the human population:  “By destroying habitats we force animals into closer contact with people… And as the human population grows, people and their livestock are penetrating ever deeper into remaining wilderness areas, wanting more space to expand their villages and to farm.”
