A University of Georgia biologist will explore the ways in which extinctions are affecting our relationship with the natural world in a presentation at the Oconee Rivers Audubon Society’s next meeting at 7 p.m. Thursday, Nov. 5, at Sandy Creek Nature Center.

Georgia professor Mark Farmer, director of UGA’s Division of Biological Sciences, will give a talk on “The Last Penguin: How Extinction Is Changing Humanity.” Farmer’s presentation will touch on how land use and other human activities are affecting the composition of the atmosphere and the chemistry of the oceans, perhaps contributing to the current wave of plant and animal extinctions.

Farmer will discuss the growing evidence that humans are helping to bring about a sixth mass extinction event, why so many extinctions are changing our relationship to the natural world, and how this wave of die-offs compares to past great extinctions like the meteor strike that many scientists believe doomed most of the dinosaurs on Earth.

The Oconee Rivers Audubon Society will launch its 2015-16 season with a reception and a special presentation about “The Wonderful World of Warblers” by research by scientist Dr. Richard Hall on Thursday, September 3, at UGA’s Odum School of Ecology. Hall, a population ecologist with the Odum School of Ecology, will explore the fascinating lives of more than 30 warbler species that breed in Georgia or migrate through the state.

A lifelong bird-lover, Hall will provide useful pointers about identifying warblers by sight, sound and habitat, offer tips for attracting warblers to your back yard and point out some nearby places to view migrating and nesting warblers.

The chairman of the Oconee River Land Trust (ORLT) board of directors will explain how the organization works to protect critical habitat and important farmland throughout Georgia at the next meeting of the Oconee Rivers Audubon Society, set for 7 p.m. Thursday, May 7, at Sandy Creek Nature Center.

Dan Hope, long-time conservationist and a founder of Sandy Creek Nature Center, will speak on “Someone to Watch Over These,” about the role of the nonprofit ORLT in permanently protecting diverse habitats through the conservation easements it administers in partnership with landowners all over the state. ORLT is coming off a banner year in 2014, when it placed more than 6,000 acres of land in conservation easements, added staff and opened a new office in Athens.

A long-time advocate for a better relationship between beavers and humans will explore the animal’s keystone role in creating and maintaining bird-friendly wetlands at the Oconee Rivers Audubon Society’s next meeting, set for 7 p.m. Thursday, April 2, at Sandy Creek Nature Center.

Bob Kobres, an engineer who retired from University of Georgia Libraries, will give a presentation on “Beavers and Us: How We Can All Benefit from Learning to Coexist with This Ancient Wetland Engineer."

A population ecologist from the University of Georgia will describe conservation efforts to reduce threats to the majestic monarch butterfly – one of her research specialties – at the Oconee Rivers Audubon Society’s next meeting, set for 7 p.m. Thursday, March 5, at Sandy Creek Nature Center.

Dr. Sonia Altizer, whose UGA research focuses on animal migration, monarch butterfly ecology, and host-parasite interactions, will give a talk titled “Monarchs in a Changing World: Status and Conservation of an Iconic Butterfly.”

An ornithologist who’s served as the Altamaha Riverkeeper’s “Coastkeeper” since last spring will describe her work in one of the largest river basins on the Atlantic seaboard and give a status update on American Oystercatchers in the Altamaha delta at the Oconee Rivers Audubon Society’s next meeting, set for 7 p.m. Thursday, Feb. 5, at Sandy Creek Nature Center.

Members will be sharing their birding stories and experiences at a special “Members’ Night” for the Oconee Rivers Audubon Society’s next meeting, at 7 p.m. Thursday, Jan. 8, at Sandy Creek Nature.

Members will share a story, a poem or a series of photos or drawings related to birds or birding in five-minute time slots during Members’ Night. Speakers can give a short presentation on anything from a trip report to an interesting or humorous encounter with a backyard bird; illustrated talks are limited to five PowerPoint slides.
