September 27, 2022 at 7:00 p.m. – Gaia, a Photographic Celebration of Flora and Fauna with Peter Rasberry

Gaia was the Greek earth goddess, or Mother Earth, who in mythology gave birth to the Mountains, Sea and Sky. Gaia is also Dr. James Lovelock’s theory of Earth as a self-sustaining organism.

June 28, 2022 - Canada’s Rachel Carson: Louise de Kiriline Lawrence and the Mid-Century Songbird Decline with Merilyn Simonds

Through the mid 1900s, amateur ornithologist and nature writer Louise de Kiriline Lawrence tracked the sharp decline in warblers and flycatchers in northern Ontario and linked it to the roadside spraying of toxic chemicals—a decade before Rachel Carson’s Silent Spring sounded the same alarm. Louise emigrated to Canada in 1926, setting up a Red Cross Outpost in Bonfield, Ontario, where she later became nurse-in-charge of the Dionne Quintuplets. Disturbed by the media circus around the infants, she built a log cabin on the Mattawa River and spent the next 50 years studying birdlife and writing almost a hundred articles and six books about species that were diminishing before her eyes.

May 31, 2022 - Ontario Big Year with Geoff Carpentier - Webinar

In 2021 Geoff Carpentier decided to go for an “Ontario Big Year”, a personal quest to see as many bird species as possible in the province over the course of a calendar year. Geoff described the planning & necessary communications, and the dedication required to seek out the rare birds that turned up. Geoff missed a few but was able to find nearly every species he sought out and in the end tallied 343 species, the second highest ever achieved! It was an entertaining account of his year in review.

April 26, 2022 - Wild, Weird and Wacky Weather with David T. Chapman - Webinar

In a country that is so vast and surrounded by large oceans, it is no wonder we have some of the most interesting weather in the world. It offers such a variety all year round because of its terrain, temperature variations and location. Learn about Fallstreak Holes, Superior Mirages and discover how far south the Aurora Borealis can actually be seen. This presentation covers the uniqueness of North America's weather, power and beauty all wrapped up into one great show.

This presentation will explore life histories, how to find moths, the main families and fun facts about them.

James Kamstra is a local ecologist who is familiar with, and has studied many facets of natural history.  Insects are a particular passion.  He started collecting insects more than 50 years ago, but now uses a camera to record his findings.

June 22, 2021 - Oak Ridges Moraine Conservation Plan and the Greenbeltwith Victor Doyle - Webinar

Ontario’s Greenbelt, including the Oak Ridges Moraine Conservation Plan, plays an integral role in conserving Durham Region’s rich natural heritage and biodiversity. Victor Doyle will provide historical and factual insights into the creation of these plans as they apply to the regional landscape while identifying ongoing challenges and opportunities.

From 1988-2017 Victor was at the epicenter of designing and implementing provincial plans in the Greater Golden Horseshoe. Best known as the “architect” of the Greenbelt, he was also instrumental in developing the Oak Ridge Moraine Conservation Plan, Growth Plan and Lake Simcoe Protection Plan

Bats are amazing! But these animals, so critical to our environment and economy, are declining in Canada and abroad. Join bat expert, Karen Vanderwolf from Trent University who will teach us about the wonders of bats, and how their survival is threatened by a deadly fungal disease, White-nose Syndrome. Karen will also explain how the Canadian Bat Box Program is working to conserve bats so our night skies will remain full of these fascinating flying mammals.

April 27, 2021 - Wild Algonquin with Michael Runtz - Webinar

Michael’s association with Algonquin spans nearly 50 years. He has explored the far corners of this famous park and has interacted with, and intimately photographed many of the wild species found there.  He hosted the international television series Wild by Nature, authored and illustrated 14 natural history books including Algonquin Wild.  In addition, Michael has written more than 1,100 natural history articles for newspapers and magazines. When not roaming the wilds, Michael teaches Natural History and Ornithology courses at Carleton University.

March 23rd, 2021 – Life in the Desert by Mark Dorriesfield - Webinar

Deserts may be harsh, dry, unforgiving places, but that doesn’t mean there is nothing to find there! From giant cacti to Joshua Trees, thrashers to roadrunners, rattlesnakes to Gila Monsters, these environments are home to some amazing plants and animals adapted to thrive under these difficult conditions.  Mark will take us through three of North America’s four major deserts, the Great Basin, Mojave, and Sonoran, describing the different habitats and the wildlife found within them. Mark is a biologist who has conducted avian fieldwork throughout North America over the past 9 years. He is particularly fond of the American Southwest, having spent 5 of those seasons working and exploring Nevada and Arizona.

February 23rd, 2021 - The Cross Canada Adventure of Sonya and Sean - Webinar 

Sean and Sonya are passionate about nature, birding and exploring new places. In June 2019 they left their jobs, sold their house, and began walking The Great Trail of Canada from Cape Spear, Newfoundland to Victoria, British Columbia. They will continue the journey north by canoe from Edmonton, Alberta to Tuktoyaktuk, Northwest Territories. They are not just looking for adventure – they are walking and paddling to connect families and youth to nature through birding and to raise awareness of the importance of the boreal forest. This journey is about connections – people to people, people to nature, past to present, and coast to coast to coast. To learn how their adventure is unfolding, join NDN for a webinar presentation at 7:00 p.m. on February 23!

November 24, 2020- Asian Carp with Andrew Reeves  - Webinar

Four species of Carp native to Asia have been introduced into the southeastern U.S. and are wreaking havoc as they overwhelm and alter aquatic ecosystems.  They are likely to invade southern Ontario in the next few years thereby changing our waterways forever.  Andrew will tell the story of these fish, how they got here and what it means. Andrew Reeves is an author and geographer who has recently published "Overrun: Dispatches from the Asian Carp Crisis", a bestseller which examines the history and impact of the four carp species in North America.

September 22nd, 2020 - Bats with Dr. Christina Davy – Webinar

Bats have been long misunderstood and even feared, but research in recent decades has provided much insight into their mysterious lives and their role in the ecosystem. Bat populations have suffered significant population declines from White Nose Syndrome and from wind turbines. Christina will present on issues around bat conservation. Dr. Davy is a research scientist with the Ministry of Natural Resources and Forestry, and is also an adjunct professor at Trent University. Her varied research has involved genetic and behavioural responses of small and declining wildlife populations to environmental changes.  

June 23rd, 2020 - 20 Years of Butterfly Counts with James Kamstra - Webinar

Butterfly counts involve groups of dedicated volunteers who spend an entire day in the field to seek out and count all the butterflies they encounter. After 20 consecutive years of these counts, much data has been assembled and some trends in butterfly populations have become apparent. James will highlight the observed changes in some species and describe how the counts have given us greater understanding of the local butterfly fauna.  James Kamstra is an ecologist who has coordinated two butterfly counts in Durham for the past 20 years. He is the Ontario Regional editor who compiles all of the provincial counts for the North American Butterfly Association.
