Sunday, September 24, 2023
2:30 – 4:30 PM

National Wildlife Federation Building 
11100 Wildlife Center Drive
Reston, VA 20190


Mark your calendar now for the next Audubon Afternoon on September 24. After catching up with your ASNV friends, you will enjoy a presentation by the Smithsonian’s Nathan Cooper. He will discuss his research on North America’s rarest songbird, the Kirtland’s Warbler. Over the past few decades, Kirtland’s Warblers have undergone a remarkable recovery, from just 167 males in the world in 1987 to more than 2,200 males today. In addition to having a compelling conservation story, its small population size and restricted breeding and winter ranges provide an opportunity to learn more about the fascinating and interconnected annual cycles of songbirds. Cooper will take the attendees on a journey through the annual cycle of the Kirtland’s Warbler and share what we have learned from this rare species. FREE! No registration required, but you may wish to register to get an email reminder of the event.

Join your friends on Sunday afternoon for this quarterly live Audubon Afternoon at the National Wildlife Federation Building, 11100 Wildlife Center Drive in Reston.

There will be an informal gathering starting at 2:30 so you have an opportunity to reconnect with everyone. Please feel free to bring any food and drink you would like to share with everyone during the informal portion of the program. At 3:00 PM, we’ll have a presentation by the Smithsonian’s Nathan Cooper.

Nathan Cooper is a behavioral ecologist and conservation biologist. He studies how migratory birds interact with each other and their environments throughout the annual cycle. He is primarily focused on the ecology and conservation of the Kirtland’s Warbler, and is currently involved in several science- and conservation-based projects with this recently delisted species. Cooper earned a B.S. in Fisheries and Wildlife from Michigan State University, an M.S. in Biology from Portland State University, and a Ph.D. in Ecology and Evolutionary Biology from Tulane University. He first joined the Smithsonian Migratory Bird Center as a Ph.D. student in 2008, and was awarded both Predoctoral and Postdoctoral Fellowships there, before being promoted to Research Ecologist in 2020.

Registration is not required, please bring friends, family, neighbors, etc!



ASNV Presents Fall Butterfly Identification with Larry Meade, September 5th

Click here for registration information.

The sight of butterflies fluttering around on a warm day is one of the most iconic signs of summer, but they can still be found well into the fall months. These beautiful insects usually live for only a few weeks as adults, but they make quite an impression while they are in their full glory. There is a large variety of butterfly species in our area. Larry Meade will walk participants through the common species and help us differentiate some of the trickier look-a-like species.

Participants are encouraged to register for the North American Butterfly Association (NABA) Count to be held on September 10, 2023.

A good way to prepare this program is to review Butterflies of the Mid-Atlantic, a Field Guide, by Robert Blakney and Judy Gallagher. Judy Gallagher is a member of the ASNV Board, and the field guide is available for purchase on the ASNV website.

Larry Meade is president of the Northern Virginia Bird Club and a member of the ASNV Adult Education Committee. He is a frequent bird walk leader and has been involved in numerous Audubon Christmas Bird Counts and North America Butterfly Association (NABA) Butterfly Counts. He is the compiler of the Alexandria Circle NABA Butterfly Count.

This program is FREE for members of Audubon Society of Northern Virginia and members of the Northern Virginia Bird Club.


Understanding the Climate Crisis with Bill Young, Five Sessions: September 19th, 21st, 26th, 28th and October 3rd

The climate crisis is the biggest issue facing humans and the natural environment in the 21st century.

This five-part course will help people be better informed about the scope of the crisis and the science behind this issue. Each class will last about an hour and a half, with opportunity for discussion. Our speaker, Bill Young, has a great thirst for knowledge and the ability to communicate complex issues in an understandable narrative.

Topics to be covered include:

  • Overview of climate concepts and issues

  • Greenhouse gases

  • Effects on birds and biodiversity

  • Fossil fuels

  • Transportation and agriculture

This class will be followed on Thursday, October 5, by a free Climate Crisis Action & Advocacy Workshop with Bill Young and Board Member Tom Wood. This program is open to all. Please post to social media and invite your friends & family to participate. The workshop will provide participants with suggestions for actions that we can all take to push back on the effects of climate change. We hope that participants in this lecture series will attend that workshop.

Bill Young is a writer who lives in Arlington. He is the co-creator (with Ashley Bradford) of the website, and he has taught numerous classes for ASNV.

Your ticket will cover all five sessions, 7.5 hours of program time. This program will be held on September 19, 21, 26, 28, and Oct 3, 7:00 – 8:30 PM. You will get a zoom link on September 19 that will be the same link for all five sessions. Sessions will be recorded and the videos will be shared with all registered participants.

VMN Continuing Education Webinar: Community Generated Data Informs Our Understanding Of the Vulnerability Of Frog and Toad Species To Climate Change, July 24th

Monday, July 24, 2023
12:00-1:00 PM

Pre-registration required

Description: To mitigate climate change-driven biodiversity loss using limited resources, conservation biologists and wildlife managers often use assessments to prioritize species that are at risk of extinction. But some assessments require a lot of data which isn’t available for all species. These data-poor species might be overlooked, delaying actions that could reduce their extinction risk. In this webinar, you’ll see how community generated data aids assessments of climate change vulnerability by placing data-poor species on the same scale as data-rich species through an example for 90 species of frogs and toads in the US.

Presenter: Traci DuBose is an ecologist who enjoys working to conserve animals with complex life cycles for future generations. After receiving a PhD from the University of Oklahoma studying stream ecosystems, she leveraged available data to inform the conservation of frogs, toads, and red cockaded woodpeckers at Virginia Tech. She currently is an Oak Ridge Institute for Science and Education program post-doctoral fellow investigating the cause of enigmatic freshwater mussel declines as a part of a large interdisciplinary team.

*Note: As always, the VMN CE Webinar will be recorded, and the recording will be available on the VMN Continuing Education Webinar Series webpage within two weeks of the webinar.

Blue Ridge PRISM Summer Meeting: “These Are Not Your Grandpa’s Quail”, July 19th

Wednesday, July 19, 2023
11:30 am – 1:00 pm
via Zoom


The northern bobwhite aka bobwhite quail (Colinus virginianus) is the only quail native to eastern North America. Its clear, whistled call was once a common sound throughout its range. You hear its call much less often now because of a steep decline in the bobwhite quail population, mostly due to habitat loss. For its Summer Meeting, Blue Ridge PRISM will welcome Marc Puckett, a certified wildlife biologist and the Small Game Project Leader for the Virginia Department of Wildlife Resources. He will discuss the bobwhite quail and how to manage its habitat in multiple scenarios so that these birds can thrive.

This is a free online event and includes a question & answer period with the audience. Those who register will receive access to the recording.

This event is put on by the Blue Ridge PRISM. Please direct any questions to them.

Vernal Pools: Introduction to a Unique Wetland Habitat, August 2nd

Vernal pools, also known as ephemeral or seasonal pools, are an important yet often overlooked wetland. As the name suggests, they are temporary pools only holding water for a brief time each year. During that time, they are home to mysterious shrimp, developing dragonfly larvae, and are critical breeding grounds for several of our local salamander and frog species. These vernal pools are in rapid decline due to development. Join Loudoun Wildlife Conservancy’s Jenny Erickson for a look into the wildlife that utilize these pools and what we can all do to help protect these sensitive wetlands. This program is co-sponsored with the Loudoun County Public Library.
