Initial Summary of Ft Belvoir CBC, 1/2/05
The Fort Belvoir CBC took place Sunday, Jan 2, 2005. This was the 61st count
for the modern circle established by Jackson Abbott in 1941 and centered nr
Pohick Church in Fairfax Co. The following summary is based upon preliminary
reports; nearly all teams and Sectors have reported. A total of 116 species
were tallied for the circle (pending acceptance of documentation for at least
one); average = 116 (N=20).
The highlight of the count was 2 Common Ravens over the BLM Meadowood Property
near Gunston Rd in Fairfax Co – there are no prior records of this species in
the circle. Congratulations to Chris Kessler, Ron Staley and Lucy Uncu for
finding these birds! The addition of Common Raven brings the total number of
historical species found to 175.
The following unusual species (noted 5 times or less in the previous 20 counts)
were reported.
American Bittern, 2/20, last = 12/31/95, Occoquan Bay NWR in Prince William Co
by Jay Keller and Kurt Gaskill, called during commotion of King Rails
responding to our audio playback.

The following hard-to-find or irruptive species (11 to 18 times in the last 20
yrs) were reported: Black Vulture (13/20, easy to find NOW - great example of
winter range expansion; 15 years ago you would be hard pressed to find Black
Vulture in the circle!), Snow Goose (16/20), Mute Swan (14/20, Prince Georges
Co), Wild Turkey (11/20, recently established breeding population in several
locations), King Rail (11/20, last = 1/4/04, 3 individuals at OBNWR noted),

Special thanks to the Sector Leaders who once again did an outstanding job:
Georg Morduch, Mary-Carroll Potter, PJ Dunn, Sherman Suter, Greg Fleming, Bart
Hutchinson, Linda Millington, Larry Brindza, Jim Waggener, Carol Ghebelian, and
Rich Rieger. I also owe over 140 thank you’s to a fantastic group of
volunteers who came out and beat the bushes to find birds and add to our
understanding of winter bird life in this metropolitan area. Also, I must
mention my appreciation to Charles Studholme of One Good Tern for sponsoring
this CBC. Lastly, special thanks to Cher who provided homemade potato-leak
soup, ham sandwiches, a selection of dips, brownies and cheesecake (from
Linda), and various beverages to the lot of us who made the species tally and
joked about who fell into what mud hole.
Great Times!
See ya-all next year!
