The Glade Springs VA Christmas Bird Count begins tonight (Fri.) at midnight
with most count parties going afield at dawn Saturday to find pleasant weather
and good birding conditions. However, birders should be cautious of possible
pre-dawn fog and early daylight fog in the count area.
Point Forecast: 1 Miles SW Chilhowie VA
36.81N -81.7W (Elev. 2099 ft)
Saturday: Partly sunny, with a high near 53. West wind between 5 and 10 mph.
A rapidly moving weather front is passing through our area at 6:00 p.m. Friday.
It will continue to move northeast at 45 mph across Northeast Tennessee and
Southwest Virginia. Behind it comes a high pressure which will likely produce
active birding. It will provide improving conditions.
The Bristol Christmas Bird Count should be productive with large numbers of
birders and many talented and proven birders in all parties. Waterfowl and
other related water birds are in the area in good numbers with the possibility
of valuable diversity. The passing front clearing Saturday may shift the
population of ducks by Sunday's count but the dependable gull, buffleheads,
ring-necks and mergansers should hold. Quick snapshots of key wintering areas
in the count circle suggests they are in good numbers and concentrations facing
into count day.
