Join the Northern Virginia Bird Alliance and their partners at DC Bird Alliance for a Winter Crow Watch at the Shirlington roost located in Arlington, VA. You’re in for a show as the crows gather here in numbers so large it actually appears on radar!

Plan to meet around 4:30pm at the Shirlington Library, near the Harris Teeter located at 4200 Campbell Ave, Arlington, VA 22206. Here participants will listen to a brief presentation (more details to come soon) before everyone walks together to the viewing point on the top floor of the parking garage at the west end of the Village at Shirlington (about a two-minute walk.)

Here the organizers have binoculars and scopes for participants to use to view the crows as they gather for a noisy social time before heading to the roost for the night. Participants can watch the crows for about 60 minutes, depending on weather conditions and crow activity. Remember to dress warmly!

Pre-registration is not required for NVBA Bird Outings, but it helps us prepare and allows us to contact participants in case of last-minute cancellations (see cancellation policies below.) Otherwise, the outing will take place as scheduled.

Keynote Speaker:

Bill Cullina, The F. Otto Haas Executive Director & Morris Arboretum & Gardens of the University of Pennsylvania

Sugar, Sex, and Poison: Shocking Plant Secrets Caught on Camera

Are we humans masters of our world, or are plants really the ones in charge? What they lack in locomotion, they compensate for in structure and chemistry. Celebrated author and botanist Bill Cullina, Executive Director, Morris Arboretum and Gardens, will explain why plant life is at the center of a carefully balanced natural economy that is critical to the functioning of our ecosystems. Through photosynthesis, plants produce the energy that powers the food chain. And although eaten by others, they are far from helpless prey, having evolved a dizzying arsenal of relationships to create ecologically sound landscapes.

Black-Footed Ferrets: The Road to Recovery, January 20th

Tuesday, January 20, 2026
7:00pm – 8:30pm

Sign up on Zoom to watch live stream or on demand

Free

Speaker: Paul Marinari, retired biologist of the Smithsonian’s National Zoo and Conservation Biology Institute

Half a century ago, scientists believed the last black-footed ferrets—the only ferrets native to North America—had gone extinct. Today, their recovery marks one of the most hopeful conservation stories of the 20th and 21st centuries. In this kickoff lecture of 2026, discover how this endangered species rebounded with Paul Marinari, a retired biologist with the Smithsonian’s National Zoo who assisted in the ferret’s recovery for much of his career. Paul will discuss how black-footed ferrets are a unique part of the North America Great Plains and what led them to become endangered. He will also highlight the role the Smithsonian and its scientific research played in their reproduction, genetics and animal husbandry, and offer an update on recovery efforts to date.

This event is part of the Smithsonian Environmental Research Center (SERC)’s free evening science talks, and it will be recorded. Closed captions will be available during the live stream and on the recording. By signing up on Zoom, you’ll be able to watch live and receive a link to the recording a few days after the live stream. SERC seeks to showcase a wide variety of topics and perspectives for its evening science talks. Views expressed during these talks belong to the individual speakers and not the Smithsonian.

Woodmarsh Trail Observation Deck at Elizabeth Hartwell Refuge

Tundra Swans are known for their striking white plumage and long, graceful necks, making them a favorite among birdwatchers. Each year, these incredible birds undertake a remarkable migration from their Arctic tundra breeding grounds to warmer winter habitats. Along the way, they face numerous challenges, including harsh weather and the need to find suitable feeding areas. During your visit, you’ll learn about their impressive strength and stamina as they fly thousands of miles to return to the tundra they call home.

Meet rangers stationed at the observation deck at the Woodmarsh Trail within the Elizabeth Hartwell Mason Neck National Wildlife Refuge. The Woodmarsh Trail Observation platform is approximately 1 mile from the parking lot. The trail is unpaved with slight elevation changes. The trail offers a longer loop to the observation platform if you like.   Please stay tuned to the website for any weather-related changes to the program.
