Subtle Signs of Evolution in Marsh Wrens *** (new location !!)
This meeting on February 25, 2018 at 2:00 p.m has now moved to a new location here is the revised information.
The basic processes of evolution are happening in every generation in every species, but they are almost impossible to observe. They are typically slow and subtle. 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. Historically, Dyke Marsh was the only known nesting area of the marsh wren in the upper Potomac River tidal zone. Sadly, their numbers have been steadily declining and surveyors have not confirmed breeding marsh wrens since 2014, probably largely because of habitat loss, but the cause has not been definitively determined.
This free, public program will be at 2:00 p.m. at the Mount Vernon Governmental Center, 2511 Parkers Lane, Alexandria 22306. This is between the George Washington/Mount Vernon Memorial Parkway and
U.S. 1, just off Sherwood Hall Lane, behind the Mount Vernon Fire Station. Parking is available here and across the street at Whitman Middle School.
Post-Hurricane Report: How Are The Birds?
People continue to suffer across the Caribbean, Puerto Rico, and the southern United States as the impacts of Hurricanes Irma and Maria linger. At American Bird Conservancy, our hearts go out to everyone affected by these storms.
One question we continue to hear from our community is “How are the birds?” While it’s difficult to gauge exactly how each species is faring at this early stage of recovery, we’ve pulled together a list of some of the bird species that may have been impacted, focusing mostly on those of conservation concern that are top-of-mind for us.

Birding on a Budget: A Complete Guide for Kids and Adults
A friend of the club Laura Pipitone sent us this great link as it relates to birding in general particularly to Youth Birding. She and her daughter, Michelle were doing some research looking for birding tips and ideas for the summer and in finding an educational program and came across our club website. They also came across another page that they used for their project,
This page has some great information about bird watching and they were willing to share it with us case we were interested listing resources for others to find.
A Cup of Joe that’s Also good for the Birds
Most of us can’t begin the day without a cup of coffee. Coffee is a major agricultural crop in many Central and South American countries and a multibillion-dollar industry around the world. Like many other crops, acres of cultivated coffee plants can have a negative effect on its surrounding habitat and wildlife. Deforestation to clear land for coffee in the American tropics means fewer trees for non-migratory birds and the migratory birds that fly south for the winter, impacting the survival of both.
On Earth Day weekend, April 21-23, the Smithsonian will convene the first Earth Optimism Summit, a three-day event focusing on what is working in environmental conservation worldwide and how these efforts can be advanced and replicated. Bird Friendly coffee, an initiative spearheaded by the Smithsonian Migratory Bird Center (SMBC), is one of the conservation success stories that will be shared at the summit.

Help Expand e-Bird Photo ID
The magic of the Photo ID tool comes from the 2.5 million bird photos that eBird users have submitted with their checklists. You can help us expand this amazing tool to new areas, simply by drawing boxes around birds. Each box improves our computer vision algorithms—boosting the accuracy of the Photo ID tools. Who doesn’t like to view cool bird photos and contribute to cutting-edge research at the same time? Help us out! Cornell is looking for more birders to post photos in their e-bird lists, so that the Merlin app for bird ID using photos will have more to learn from. submitted by Dixie Sommers
- Communication options from the Club
Over the last several years the Club has added a range of communication and social media options in addition to continuing some long standing ones. The Board has adopted an Overview and Purposes of NVBC Communications Channels, both to inform members and to record the decisions made about these means of communication. The Overview can be found at this link below:
