March 2021


March 5, 2021 @ 7:00 pm - 8:00 pm

Maine’s iconic American chestnut trees were decimated by an introduced blight during the early 20th century. Today, plant scientists are using modern genomic techniques along with traditional backcross breeding methods to produce healthy seedlings that can both resist the blight, and withstand Maine’s harsh winters. Al Faust, President of the Maine Chapter of the  American Chestnut Foundation, will discuss the current status of the restoration process, and how volunteers can help with the replanting and seed collection effort in eastern…

Birding Cuba by Ron & Lee Davis and Nancy Larson

March 16, 2021 @ 7:00 pm - 8:00 pm

In January 2020, Ron, Lee, and Nancy traveled through much of Cuba with a group of American birders for 13 days.  They found about half of the large tropical island's 350 species.  Among those seen and photographed were 22 of Cuba's 26 endemics—most of which are of concern for survival.  At the same time, the three Mainers experienced a culture and economy different from ours, yet only 95 miles away. Free for members, $7 for non-members. Please register online at…

Roads, Rain, and a Couple Thousand Amphibians – Call it a Big Night!

April 6, 2021 @ 4:00 pm - 5:00 pm

Big Nights are fascinating and unique natural events that occur every spring. With spring rain and warming temperatures, frogs and salamanders move to their breeding grounds by the truckload. However, these miniature migrations often put them in harm's way on roads. How we can assist and protect these ancient populations will be the subject of this presentation.  Greg LeClair is a graduate student in Ecology and Environmental Science at the University of Maine. As the creator of the "Maine Big…

Maine’s Great Migration

April 26, 2021 @ 7:00 pm - 8:00 pm

Each spring, millions of adult alewives make their way up Maine’s rivers and streams and into their natal lakes to spawn.  Along the way, these determined members of the herring family attract the attention of a wide range of wildlife.  Join David Lamon as he leads you through one of Maine’s great natural history events.   We’ll discuss the conservation successes and challenges of restoring Maine’s migratory waterways. Free for members, $7 for non-members. Please register online at www. https://maineaudubon.org/events/ NOTE:…

May 2021


May 7, 2021 @ 7:00 pm - 8:30 pm

Wood turtles are endangered in Maine, listed as a Priority I Species of Greatest Conservation Need.  However, they are difficult to monitor in the wild using standard visual surveys.  Environmental DNA (eDNA) is a relatively new technique that allows scientists to identify species DNA (from feces, blood, saliva, etc.) found in water samples taken from areas with suitable habitat.  This allows for a much more accurate population estimate of difficult-to-detect species.  However, the technique has not been closely studied for…

June 2021


June 20, 2021 @ 12:30 pm - 6:00 pm

Seal Island National Wildlife Refuge offers ideal habitat for a large colony of Atlantic puffins.  Razorbills, black guillemots, common and Arctic terns, and common eiders also nest here, and it’s the southernmost breeding colony for the great cormorant. Northern gannets and common murres are occasionally seen diving for fish in the rich waters that surround the island.  Periodically, a hungry merlin or peregrine falcon will make a pass in search of a seabird meal.  We also expect to have good…
