Virginia U.S. Senator Mark Warner came to Belle Haven Park/Dyke Marsh on June 22, 2020 and championed the Senate’s June 19 approval of the Great American Outdoors Act.  The bill would fully and permanently fund the Land and Water Conservation Fund (LWCF) at $900 million a year and allocate $9.5 billion to address the maintenance backlog on public lands, including national parks, refuges, U.S forests and other lands.   The National Park Service has a $12 billion maintenance backlog; Virginia parks, $1.1 billion; the George Washington Memorial Parkway, $717 million.

Visitors to Dyke Marsh will find a photography station called Chronolog on the Haul Road trail at the native plant site, DMW-101. Unfortunately, our second station  on the boardwalk across from Tulane Drive, DMW-102, was destroyed twice. Neither FODM or the U. S. Park Police know why it was apparently vandalized. At this time, FODM will not replace it at that site

This station helps document and better visualize landscape changes over time in the preserve. Changes in a landscape can be slow to see, whether they are seasonal changes, results of the restoration project or longer-term changes.

Several talented photographers documented breeding birds in Dyke Marsh this spring, 2020.

Many people have enjoyed warblers migrating through Dyke Marsh this spring, 2020. Many species have bright colors. Some migrate from South America to northern Canada.

Keen observers have watched the parents and two young barred owls (Strix varia) in Dyke Marsh this spring, 2020. Ed Eder captured the two owlets doing mutual preening on April 17 and Ed reported that they usually stick close together.

Barred owls are known for their haunting, baritone night call, “who cooks for you, who cooks for you-all.”  They get their name from their “bars” or striped plumage. Generally, they roost during the day and hunt at night. Adults are around 21 inches in length and a little over a pound in weight. They tend to be in older forests, but are highly adaptable to varied habitats, including mixed forests and disturbed areas. “Barred owls are the opportunists of the owl world,” wrote Leigh Clavez in The Hidden Lives of Owls.

Dyke Marsh has had another first this spring, 2020 -- several sightings of a yellow-headed blackbird (Xanthocephalus xanthocephalus). In fact, it is a record for the George Washington Memorial Parkway according to Brent Steury, the Parkway’s Natural Resources Program Manager.

The beautiful blackbird in Dyke Marsh is a male with a stunning yellow head, black body, yellow breast and white markings on its wings. Females and immature males are brown-black with reduced yellow on the face, throat and brow. These birds typically nest in the West and Midwest in colonies, often alongside red-winged blackbirds in bullrushes or cattails. They forage on insects, grain and wet seeds.

An osprey (Pandion haliaetus) was a victim of a bald eagle (Haliaeetus leucocephalus) attack on Sunday afternoon, March 22, 2020.  The bald eagle may have attacked the osprey trying to defend his or her territory or because of what is called kleptoparisitism when one species steals food from another.  The osprey came to the ground after the attack and was stuck in some bushes.  FODMers Rich Rieger and Sherman Suter extracted the bird and Rich wrapped it up in his coat.  Despite some bleeding, the osprey settled down and Rich placed the bird on a picnic table.  After a moment, the osprey took flight, seemed normal to the human eye and landed in the top of a tree.

On March 20, 2020, around 7 a.m., several FODMers observed that the water in west Dyke Marsh and an unnamed stream flowing in the marsh was neon green.  This part of the marsh is around 15 to 20 acres and west of the George Washington Memorial Parkway.

We contacted local, state and National Park Service officials. Fairfax County sent wastewater and hazardous materials staffers, the Virginia Department of Environmental Quality sent pollution experts and the National Park Service sent a staffer, all to inspect the site.

On March 1, 2020, Shenandoah National Park biologist Rolf Gubler described the peregrine falcon (Falco peregrinus) restoration project to a packed room of 80 enthusiasts.  This project in the park is a partnership of the National Park Service (NPS), William and Mary College’s Center for Conservation Biology (CCB), the Virginia Department of Game and Inland Fisheries (DGIF) and the Virginia Department of Transportation (VDOT).

In early January 2020, FODMer Ed Eder photographed a rare visitor flying over Dyke Marsh, Ross’s goose (Anser rossi), which National Park Service biologist Brent Steury said was a new record sighting for the George Washington Memorial Parkway.

This goose is white with black wingtips and considered the smallest of the "light" or snow geese. Ross's goose has a short neck, rounded head and a stubby bill with no "grin patch" seen in its larger cousins due to their curved tomium, the cutting edge of the bill, Ed explained. More mature birds, particularly males, have warty gray tubercles at the base of their bills, said Ed.

On December 2, 2019, the Fort Hunt Herald newspaper published an interview with FODM President Glenda Booth, in which she discusses the marsh restoration project, emerald ash borer infestation, the native plants project, bald eagles and more.  Visit here to read the entire article.

On November 13, 2019, at FODM’s quarterly meeting, Dr. Sally Valdes outlined several ways that climate change is adversely affecting wildlife.  Introducing the topic, she said that carbon dioxide and other greenhouse gas emissions have risen to levels unprecedented in the last 800,000 years.  Carbon dioxide concentrations have been tracked continuously at the Mauna Loa Observatory in Hawaii since 1958 and the trend has been steadily upward, from about 315 parts per million (ppm) to 414 ppm in the spring of 2019.
