Patterson’s current research focuses on the population dynamics of deer, moose, and caribou – plus their predators. Brent Patterson joined the Ontario Ministry of Natural Resources as a research scientist in 2001 and has been an adjunct professor at Trent University since that time as well. He also holds academic appointments at several other universities to facilitate his research with graduate students and other academics. Along with his students and colleagues he has published more than 130 scientific papers on wolves, coyotes, caribou, deer and moose in Ontario and beyond. Patterson presented to OSFN in 2012, and again in 2020, to a full house, with a focus on Wolves and Coyotes.

When he’s not working, he enjoys spending as much time as possible in the woods and on the water with family and friends.This Moose talk is scheduled for 7pm Thursday, April 9, at the Harry Lumley Bayshore Community Centre.Doors open at 6:30 to browse amongst the OSFN merchandise, learn about memberships and future activities, etc.Of special interest are many nature books from the extensive collection of the late Walter Muma, available by donation to OSFN.

This American kestrel was hanging on in the wind! She seemed to enjoy the whole situation. April 3.
Now that Spring is finally here, I was especially delighted recently to go for a pleasant run and hear the beautiful warbling song of several Eastern Meadowlarks. But, I am still waiting to see them – as they were all hidden in the fog that day.
There are many other Nature themed events and talks being offered in the coming weeks: Grey Roots Spring Lectures will feature Allen Smutylo at 1pm Wednesday April 8, with his new book ‘Gold of Another Kind – The Lost Legacy of Georgian Bay.’ Details are here – https://greyroots.com/exhibit-event-program/spring-lecture-series-2026

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.
