Volunteers sought for annual
citizen-science survey.
Pennsylvania Game Commission officials are urging
wildlife enthusiasts to join the tens of thousands of volunteers throughout the
United States in the Audubon Society’s 114th Annual Christmas Bird Count, which
will take place Dec. 14 through Jan. 5.
The
Christmas Bird Count is the longest-running citizen-science survey in the world,
and the data collected through the count allows researchers, conservation
biologists, and other interested individuals to study the long-term health and
status of bird populations across North America.
Local
counts will occur on one day between Dec. 14 and Jan. 5. Volunteers can pick the
most convenient circle, or participate in more than one count. There is a
specific methodology to the CBC, but everyone can participate. The count takes
place within “Count Circles,” which focus on specific geographical areas. Each
circle is led by a “Count Compiler,” who is an experienced birdwatcher, enabling
beginning birders to learn while they assist.
Those
who live within the boundaries of a Count Circle can even stay at home and
report the birds that visit their backyard feeders.
In
either case, the first step is to locate a Count Circle that’s seeking
participants and contact the local Count Compiler on Audubon’s website,
www.audubon.org, to find out how you can volunteer.
There
is no longer a fee to participate in the Christmas Bird Count.
Dan
Brauning, who heads up the Game Commission’s wildlife diversity division, said
the Christmas Bird Count makes an indispensible contribution to conservation
because it monitors bird species that spend winters in Pennsylvania.
“Some
of these species are much easier to count or monitor in winter because their
breeding ground is so far north in areas where there are few people or roads to
give access to habitat,” Brauning said.
The
rusty blackbird, for instance, migrates from the boreal taiga forests of Canada
and Alaska to the southeastern United States in winter, Brauning said.
Pennsylvania is on the northern edge of its winter range, and it sometimes turns
up in the Christmas Bird Count, he said.
Hawks
also are more easily counted in winter, Brauning
said.
Brauning said the Christmas Bird Count is a good way to
introduce beginners to bird identification. It is much easier in winter to find
birds through your binoculars, he said.
“Birds
are easier to spot because the trees lack the leaves that hide birds from your
eyes in spring and summer,” Brauning said. “And there are fewer bird species
around in winter than at other times of year, so it is easier to learn bird
species identification. In fact, many birders got started in this hobby in
winter in a car with more experienced birders on a Christmas
count.”
