Join the Christmas Bird Count – A great Citizen Science Opportunity! (Takes Place Between December 14th and January 5th)

Photo: By Jeff Drake, Carolina Chickadee – From the Great Backyard Bird Count

The National Audubon Society’s Christmas Bird Count is one the longest running wildlife censuses in the world. The CBC began on Christmas day in 1900 as a way to conserve America’s natural heritage by counting birds rather than hunting them. This year is the 127th anniversary of that first CBC, when birders across the entire Western Hemisphere will get up early to count birds from December 14 to January 5, 2027.

Participation is free and open to bird enthusiasts of any level. There are two main ways to participate:

  • Feeder Counts: Count all the birds you see or hear from your own backyard or local park at a stationary bird feeder within a CBC circle. No binoculars or hiking required, and you can participate with less time commitment.
  • Field Counts: Survey an area (alone or in groups) during daylight hours and record all the birds you see or hear. Some counts also include nocturnal surveys after dark to record owls and other night-active species.

Visit the CBC Circle Finder to locate a count near you and register to participate. All skill levels are welcome!

Why Count Birds?

It’s a way for volunteers to monitor environmental trends in our local area, identify potential problems and share data with other organizations. Birds are the “canary in the coal mine” for our environment. Their health, abundance and distribution can signal trends in the health of the larger environment. NVBA has a long history of documenting bird life in our community and promoting conservation of birds and wildlife.

Resource managers of parks and other public lands rely on bird count long-term and geographically fixed data in their land management decisions. NVBA sends the count results to organizations—like the Fish and Wildlife Service, Bureau of Land Management, and the National Park Service—who use the information to better manage their natural resources.

Without habitat, we would have no birds.  Eleven percent (11%) or 1,111 of the world’s species of birds are at risk. Two hundred could disappear within 20 years. The primary threat to birds is habitat loss. Since 1967, there’s been a 70% decline in common backyard birds because of habitat fragmentation or development.

Your counting counts! Even if you’ve never participated in a count or survey before, you’ll be matched with more experienced volunteers who can teach you the “tricks of the trade” and help you build new skills that will add to your bird-watching enjoyment. Plus your efforts will make a difference in helping to protect our local habitats.

Mason Neck Canoe-mobile

Dateline 14 October 2026:

FMN enjoyed a most unique day of volunteering for Meadowood Special Recreation Management Area (SRMA) on the Mason Neck peninsula. The event was hosted at Pohick Bay Regional Park on an absolutely beautiful, smooth water fall day. The primary attraction was the Wilderness Inquiry canoe mobile, a traveling troop of young adventurers and paddle guides whose goal it is to bring outdoor paddle adventures to urban youth organizations across the eastern US states. Their home base is Minnesota but so far this year they have traveled from New York to Louisiana and many locations in between floating their mission. They frequently partner with Bureau of Land Management (BLM) for access to public lands. The guests this day included a 60 person public school group from Arlington in the morning and a 30 person homeschool group local to the Lorton area in the afternoon session.

The sideshows included an FMN table featuring  Turtle Talk, FMN Olivia Rivas (with Meadowood) presenting her hognose snakes, Fairfax County Department of Public Works Environmental Services (DPWES), and a birding group with owls. The format was a hour of small groups rotating between the 4 sideshows and then an hour or so in canoes out in the bay.

DoF Acorn Collection – Wrapup

The 2026 acorn collection season is now closed. Many thanks to all the volunteers who donated acorns and nuts; and a special thank you to those that monitored the bins and transported donations to the Warrenton cold storage facility.

DoF sent a nice thank you message to the chapter complimenting FMN’s contribution to the new process. Kendra Esparza-Harris, Forest Landowner Outreach Coordinator said in his message, “I would like to share my sincere gratitude for your partnership and with the Fairfax County Master Naturalist and Vienna Community Center in helping to establish and manage the various collection sites in Northern Virginia for the 2026 Acorn Collection Campaign. This year, DOF tested out a new collection process, in which your chapter was an instrumental part in allowing it to happen”. DoF employees Kinner Ingram, District Forester for Rappahannock and Jacqueline Laconi, Customer Care Specialist, provided resources.

As you recall FMN had five sites, Mt Vernon, Hidden Oaks Nature Center, Vienna Community Center, Walker Nature Center in Reston, and Fairfax City municipal center. These sites were conveniently spread around the FMN domain area so collection was fruitful. The cover photo shows storage trailers at Warrenton. Trailer on the right is for Black walnuts that do not need cold storage. Trailer in the center is the cold storage unit for all other nuts. Cold storage helps delay the acorns from sprouting until they can be transported to DoF tree farms. Trailer on the left is not currently in use.

As a way to measure success, bin stewards collected some statistics as follows:

The Mt Vernon government center bin collected approximately 90 pounds of acorns covering seven species – White oak, Shagbark hickory, Willow oak, Bur oak, Red oak, Chinese chestnut, and Pin oak.

Sarah Mayhew transported donations from multiple sites one day reporting a load of at least 40 pounds of different species. Two small bags containing chestnuts (3 lbs each), a small bag containing Bur Oak (3 lbs), a couple of small bags with Pin Oak (3 lbs), a big bag of white oak from Vienna (10 lbs), and two large bags of Red oak acorns that were probably 8 or 9 pounds each.

Bill Hafker also transported donations from Hidden Oaks Nature Center. Combined estimates from Bill, Sarah, and Kristina Watts came in as follows – Chestnut Oak 40 lbs, Pin Oak 5, White Oak 110, Red Oak 10, and Black Oak 5.

Charles Colby was the primary transporter of acorns collected at Walker Nature Center. He reported finding some nice restaurants in Warrenton he and his wife enjoyed after transporting approximately 144 pounds of acorns broken out as follows:

Total for Location: (29 bags)

  • Black Oak — 1 pound
  • Cherry Bark Oak — 2 pounds
  • Chestnut Oak — 66 pounds
  • Pin Oak — 3 pounds
  • Red Oak — 7 pounds
  • Red Southern Oak – 1 pound
  • Sawtooth Oak — 20 pounds
  • Scarlett oak — 1 pound
  • White Oak — 22 pounds
  • Walnut — 11 pounds
  • Unidentified — 10 pounds
  • Total 144 pounds

Last but certainly not least, many thanks to Fairfax City Urban Forestry employee, Sophie Chapin, who managed the bins at Fairfax City municipal center and transported a large quantity of various acorns and nuts to Warrenton. We did not get estimations as to the totals but we know they collected a significant amount. She was very helpful unloading donations at the Warrenton site as well.

Woodland Sanctuary Workday for Hidden Oaks Nature Center, November 8th

Woodland Sanctuary Workday for Hidden Oaks Nature Center

Join volunteers to help restore an area within FCPA’s Annandale Park that was formerly designated a “Native Garden maintained by Fairfax Master Naturalists.” They are turning it into a Woodland Sanctuary that can be used for educational purposes and habitat protection.  They need help installing native plants on Sunday, November 8, 9 a.m. to 12 p.m.  Earn service hours!

Please dress for the weather, bring garden gloves and water to drink. RSVP to Laura Anderko at dr.laura.anderko@gmail.com.  Please park at the playground/picnic shelter parking lot in Annandale Community Park (4030 Hummer Road) and walk up the path toward the nature center- participants will be near the campfire area.

This project is funded by Fairfax Master Naturalists 2026 mini-grant.  Hidden Oaks Nature Center staff expect that the woodland sanctuary will be visited by community members, school groups, scouts, class and camp participants, artists, and senior groups, and will bridge a connection between viewers and nature, with emphasis on the habitats and ecosystems. Because it is located on an already ADA-accessible path, the area will provide outdoor interpretation opportunities for those with limited mobility who may not otherwise be able to participate in guided outdoor walks and activities.
