Interested in the unprecedented impacts humans are having on the natural world? Please join Arlingtonians for a Clean Environment (ACE) for a free talk with the co-editor of “Living in the Anthropocene: Earth in the Age of Humans,” John Kress, curator of botany at the Smithsonian National Museum of Natural History.
Join Greg Butcher for an introduction to waterfowl identification. Get to know some of the many species that winter in the open waters of our region. The workshop costs $20.
Winter is a great time to improve your birding skills. Birds are easier to find since there are no leaves on the trees. In addition, winter brings a wide variety of ducks and geese. Several species of hawks and sparrows also call our region home during our coldest months.
The quarry is a great place to find waterfowl in winter. The woods and lake shore offer good habitat for other winter species, including resident red-headed woodpeckers. Toby Hardwick leads with Rick Purvis co-lead. Sponsored by ASNV.
The ASNV Winter Waterfowl Count will be conducted Saturday and Sunday, February 3 & 4, 2018. Volunteer teams survey the Potomac River from Algonkian Regional Park in Loudoun County south to Quantico Marine Base in Prince William County. Several important inland ponds, lakes, and marshes are also surveyed.
Meet at Lake Newport and carpool or caravan to the other Reston lakes, looking for winter waterfowl. Waterfowl are often the highlight of winter birding, when their variety is far greater than for our summer residents. Sponsored by the Reston Association and The Bird Feeder of Reston.
On February 25, 2018, Dr. Sarah Luttrell will talk about her work on evolution and speciation in the marsh wren (Cistothorus palustris). Dr. Luttrell studies how evolution works by studying subspecies of birds. She will examine how comparing multiple traits like plumage color, size and shape, vocal behavior and genetics in marsh wrens has revealed an exciting pattern of evolution in this bird.

Vulture: The Private Life of an Unloved Bird
Just in time for Halloween! Vultures are often overlooked, underappreciated, and unloved, despite the vital role they play healthy ecosystems. Worldwide, vultures are more likely to be threatened or endangered than any other group of raptor, but in the United States turkey and black vultures may be increasing in number.
Our route will take us past fields and into mixed forest. Different terrains should yield a good variety of species. Toby Hardwick leads. Sponsored by ASNV.
Monarchs and their amazing migration to Mexico are in peril for many reasons. Learn about the monarch life cycle, migration, cycle, how you can attract them to your home garden or favorite public space, and how to raise them to send them on their fall journey. Resources for milkweed and garden design also included.
