Discovering Bats in the Night Sky, October 1st

/in , , /by

Article and Photos by FMN Laura Anderko

On October 1, 2023, FMN offered a hike to its members to learn about and view bats, with expert Deborah Hammerer. The group met at Dyke Marsh trail in Alexandria, VA to discover the many bats native to the area. Deb used a sonar detector to hear the bats echolocating as they hunt for insects. The group was not disappointed! We were treated to dozens of bats including Little brown bats and big brown bats. Adding to the suspense, a barred owl called out into the night while the bats were in flight, catching insects – these birds are hunters of bats….

Deborah offered insights and information about bats. Bats belong to a group of animals called Chiroptera (Kir-op-tera), which means “hand wing.” Bats are the only flying mammal. Using a bat puppet, she described how bats fly.  Deborah described a bat’s wing resembling a human hand — with a flexible skin membrane that extends between each long finger bone and many movable joints. This makes bats acrobatic in their flight, helping them catch insects. They also use echolocation – sending out waves of sound to locate insects during flight. Each night, bats can eat their body weight in insects, numbering in the thousands, reducing disease and helping farmers. Bats are important pollinators too – over 500 plant species rely on bats to pollinate their flowers including mango, banana, guava, and agave. Bats are incredible creatures!

The evening ended with a beautiful moonrise over the Potomac…

Join us as Naturalist and award-winning Interpretive Manager Suzanne Holland presents on Southern Flying Squirrels (Glaucomys volans) – a native of Virginia. Flying squirrels are technically not fliers, but expert gliders, using the membrane between their ribs and ankles to glide. They can cover 150 feet in a single glide!  After the presentation, we will have an opportunity to observe flying squirrels from their feeding boxes.

Suzanne Holland has served Fairfax County residents for over 30 years and was honored by the County for her outstanding contributions when she retired in November 2022. Suzanne was among the first to broaden engagement to diverse communities and to train others about the importance of nature for children and families. She partnered with the Office for Children for over a decade of “teaching the teacher” programs, leading diverse county preschool teachers on methods of teaching about nature. In addition, as a member of the Mason District Task Force on Equity, Suzanne worked with Hidden Oaks Nature Center staff to create opportunities for equity programming for local Latino and Asian communities.

For millennia, owls have captivated and intrigued us. With their forward gaze and quiet flight, owls are often a symbol of wisdom, knowledge, and foresight. But what does an owl really know? And what do we really know about owls? Though our fascination goes back centuries, scientists only have recently begun to understand in detail the complex nature of these extraordinary birds.

Join Jennifer Ackerman, author of The Genius of Birds, for an author talk about her latest book, in which she illuminates the rich biology and natural history of owls and reveals remarkable new scientific discoveries about their brains and behavior. What an Owl Knows is a fascinating exploration of owls across the globe and through human history, including an account of their astonishing hunting skills, communication, and sensory prowess.

Jennifer Ackerman has been writing about science and nature for almost three decades. Her New York Times bestseller, The Genius of Birds, has been translated into 25 languages and was named one of the best nonfiction books of 2016 by The Wall Street Journal, a Best Science Book by National Public Radio’s “Science Friday”, and a Nature Book of the Year by the London Sunday Times. Her other books include Birds by the Shore: Observing the Natural Life of the Atlantic Coast (2019 reissue by Penguin Press of her first book, Notes from the Shore), Sex Sleep Eat Drink Dream: A Day in the Life of Your Body, and Chance in the House of Fate: A Natural History of Heredity. Ackerman’s articles and essays have appeared in National Geographic, The New York Times Magazine, Scientific American, and many other publications.

Thursday, November 2, 2023
7:00 PM – 8:00 PM

Virtual Meeting

Registration is required.

Fee: ASNV Members, $10; ASNV Non-members, $15

Join the Audubon Society of Northern Virginia (ASNV) for an author event and learn about the man behind the ground-breaking, 1918 Migratory Bird Treaty Act. It’s one of the country’s first and most important conservation laws and has saved billions of birds.

Will McLean Greeley will provide an overview of his new biography, A Connecticut Yankee Goes to Washington: Senator George P. McLean, Birdman of the Senate. This is the story of how Connecticut’s George P. McLean helped establish lasting legal protections for birds that is still in effect today. Greeley, McLean’s great-great-nephew, puts McLean’s victory for birds in the context of his distinguished forty-five-year career marked by many acts of reform during a time of widespread corruption and political instability.

Will McLean Greeley grew up in western Michigan with a passion for American history, politics, and birds. He earned a bachelor’s degree in political science from the University of Michigan, followed by a master’s degree in archives administration. After retiring from a thirty-five-year career in government and corporate market research, he embarked on a three-year journey of research and writing to produce the story of his great-great-uncle George P. McLean and his legacy. Greeley, married and the father of two sons, and twice a grandfather, lives in Midland, Michigan. A Connecticut Yankee Goes to Washington is his first book.

Zoom, hosted by Smithsonian Environmental Research Center (SERC)
Register here.

Our food systems have become increasingly fragile in the face of climate change, ongoing conflicts and the long-tail of the COVID-19 pandemic. More frequent—and more intense—extreme events challenge food production, storage and transportation. At the same time, how we grow, process, package and transport our food often harms the environment, further accelerating climate change and biodiversity loss. Fixing this requires bridging the gap between food policies and climate policies. Join Dr. Jessica Fanzo for a look at sustainable food practices for a hotter, more turbulent world. Fanzo directs the Food for Humanity Initiative at the Columbia University Climate School. In this talk, she’ll reveal the must-do actions to nourish 9.7 billion people by 2050.

Cownose rays are enigmatic, and sometimes controversial, summertime inhabitants of Chesapeake Bay. Smithsonian Environmental Research Center’s Fisheries Conservation Lab has been tagging cownose rays and tracking their long-distance migrations since 2014. On Sept. 19 Dr. Matt Ogburn, head of the Fisheries Conservation Lab, will reveal some of the discoveries from this 9-year tracking effort. Their studies have uncovered the rays’ overwintering habitat, documented the different migration patterns of males and females, and revealed the environmental cues that help rays know when to start migrating. These findings are helping support conservation and management of this often misunderstood and overlooked stingray.

This webinar will be recorded! Closed captioning will be available during the live event and on the recording. By signing up on Zoom, you’ll be able to join live and receive a link to the recording approximately one week after it airs.
