Bird Nerd Diary: Yellow-headed blackbird highlights Balsam bird count By
Don Hendershot
The
Carolina Field birders, friends and volunteers conducted their fourth
annual Audubon Christmas Bird Count on Thursday, Dec. 29.
According to count compiler Bob Olthoff, 22 birders participated
in this year’s count. Counters tallied a record 77 species,
besting last year’s record by two species. A yellow-headed
blackbird spotted at the test farm along Ratcliff Cove Road was
the rare bird for this year’s count. The bird was discovered
by Marilyn Westphal, Tony Scardaci, Charlotte Goedsche and Tim Carsten
as they scanned the mixed flocks of blackbirds, cowbirds and starlings.
Thanks to modern technology the bird was digitally documented.
Westphal called count compiler Bob Olthoff by cell phone. Bob and
Wayne Forsythe joined her group at the test farm and the bird was
relocated. Thankfully it was not camera shy and undoubtedly does
not have that “blurry” gene that has foiled attempts
at documenting the ivory-billed woodpecker. Forsythe was able to
get photos with one of those shirt-pocket digital cameras. Bob and
Wayne identified the bird as a first-year male.
The yellow-headed blackbird generally nests from western and central
Canada, east to the Great Lakes and south to northern Baja, California
and Arizona. It is a neotropical migrant and winters from the southwestern
U.S. to Costa Rica. The bird is a bit of a wanderer and is found
as a rare spring and fall migrant throughout the eastern U.S.
Lake Junaluska and its environs proved quite productive. Beth
Brinson and Cathy King, Junaluska section leaders, reported 50 species
from their section. Some highlights from Lake Junaluska included
canvasback, common loon, Bonaparte’s gull and snow goose.
Audubon’s Christmas Bird Count is the prototype citizen
science project. With more than 100 years of continuing data, it
is a window on the world of avian distribution and population dynamics.
This data is used by Audubon to designate Important Bird Areas and
create WatchList. Through WatchList, Audubon monitors more than
100 species of birds whose numbers are declining.
It’s the citizen science aspect that makes the annual bird
count different from most outings. Most birders, myself included,
are generally intent on seeing as many species as possible on an
outing — the more rare species, the better.
That’s not what the Christmas Bird Count is about. Audubon’s
bird count is composed of 15-mile diameter circles from all around
the world. These count circles stay constant, and participants annually
scoured them to record the number and abundance of species. Now
don’t get me wrong; there’s not a birder out there who’s
not looking for the next species, and rarities are always a thrill.
But from Audubon’s perspective, it is just as important to
record how many European starlings, brown-headed cowbirds and red-winged
blackbirds are in a mixed flock as it is to discover a yellow-headed
blackbird among them.
I have to remind myself of this scientific focus. My section of
the annual bird count is the Balsam Mountain Preserve, which I co-led
this year with Balsam Mountain Trust Chief Naturalist Blair Ogburn.
Now the Balsam Mountain Preserve is a pretty birdy place. It boasts
more than 50 species of nesting birds, and the last fall migrant
survey turned up more than 70 species. But the Balsam Mountain Preserve
in the dead of winter is a different story.
At this point in time, one can expect the winter population of
birds in the Balsam Mountain Preserve to produce a species count
in the mid-20s. As development (golf course and residential) continues
at the Balsam Mountain Preserve, this number may change. By having
a Christmas Bird Count already established at the Balsam Mountain
Preserve, biologists will be able to document how these habitat
changes affect the wintering population of birds there.
Interior forest species are currently the mainstay of the Balsam
Mountain Preserve, and while we only recorded 23 species for the
section, we did add two species – brown creeper and ruffed
grouse – to the overall list. While the yellow-headed blackbird
was surely out of its normal range, the award for long-distance
migrant this year might actually go to J.R. (Dennis) Crouse, a birder
from upstate New York who was visiting family in Waynesville. Crouse
belongs to a birding club near Buffalo and generally participates
in the annual Christmas Bird Count. Travel plans put him in Waynesville
this year on his club’s bird count date, but he was able to
get his bird count fix by calling Olthoff and volunteering for the
Balsam count.
