BIRDS
OF THE
CLEAR CREEK VALLEY
(Under
construction)
Clear Creek Lullaby
It is five o'clock in the morning.
I see nothing wrong walking alone
This old Appalachian road - tucked
in by hills - listening to birdsong.
The entire ensemble is playing:
Timpani by ruffed grouse and a chat,
Thrushes silver notes accompanying
The vireo string section in E-flat.
A Carolina wren, cheerful bard,
Yodels from a wooded rill,
Accenting tanager, oriole, bunting,
And a prairie warbler's trill.
Other than myself, the only listeners
Are a flying squirrel in his loge,
And a trio of deer gowned in beige,
Volunteer ushers, I suppose.
The genius composer though unknown
Hints in dark ways I am unaware
Of ice ages, corridors of time flown,
Of secrets insuspected in music so rare.
- Tom Thomson
The Clear Creek Valley is located in northern Hocking
and southern Fairfield counties. It is a beautiful place, the
centerpiece being a meandering, shallow stream which is set in a
landscape of lowland meadows surrounded by solemn wooded hills and
hollows which are accented every now and again by startling and
dramatic outcroppings of Blackhand sandstone. I can truly say without
fear of contradiction that this valley is one of the most beautiful
sites in the state of Ohio. The headwaters of the lovely creek are in
the vicinity of Amanda, Ohio, and the stream empties into the Hocking
River approximately 15 miles from its source to the east (82û 33' 2"
W. longitude; 39û 36' 00" latitude).
The
easiest way to get to the valley is to take U.S. Route 33 to Hocking
County Road 116. This is the Clear Creek Road and it is about 8.8
miles south of Lancaster, Ohio. There is a Shell Station and
convenience store on the corner. From here, the Clear Creek road
follows the stream westward.
If
you are coming from Lancaster, Ohio, when you are in the vicinity of
the small village of Sugar Grove, scrutinize the utility pylons in
the vicinioty of that village for Black Vultures. These electric
utility towers are favorite roosting places for birds of this species
although an occasional Turkey Vulture sometimes joins them. The Black
Vultures will look like little black nubbins setting on various parts
of the towers, sometimes low, sometimes high, sometimes as many as a
dozen or more on one structure.
Sugar Grove is also noteworthy in that it marks the
southernmost advance of the Wisconsin ice sheet in this part of the
state. This glacier as well as others that preceded it had a
tremendous impact in shaping the Clear Creek Valley. But the
Wisconsin most of all, not only because it was the most recent of
these events, but because it was truly the progenitor of the valley,
the shaping hand, the sculptor that bequeathed us the treasures we
cherish today. Consider these facts. Less than a dozen millennia ago
this glacier had smothered two-thirds of Ohio under its awesome
weight of ice. Where Columbus is located it towered higher than the
tallest buildings there now; in Cleveland it was an unbelievable half
a mile deep. Sweeping down from Canada it destroyed or pushed before
it every major vestige of life: ferns, flowering plants, shrubs,
trees, reptiles, amphibians, birds, and mammals. And this continued
for many millennia, how many we are not exactly sure, but not
withdrawing until somewhere around ten or eleven thousand years ago.
I
don't believe in flying saucers, but if there were such things, I
would prefer to think of them as visitors from our far-distant
future, manned ships from our own planet coming back through time,
checking us out, as it were, sometimes now, sometimes at Gettysburg,
sometimes at Waterloo, sometimes in biblical times. Checking out
their own past, their own history, probably wondering how they ever
made it, considering they evolved from such barbarions. If I ever
encounter such a craft and its inhabitants and they invite me for a
ride, I'll happily accept. And when they ask me where I would like to
go, I will have my answer ready: "Let's go to the edge of the
Wisconsin glacier about 12,000 years ago," I will reply. "Somewhere
down near Sugar Grove, Ohio, just north of what we now call Clear
Creek, and let us go in the springtime, perhaps in late April or May,
if that is possible." What a wonderful fantasy this is!

From 1970 through 1999, with the exception of 1973, I
conducted a breeding bird
population study in the valley which has resulted in a total of 115
species and
one sub-species being recorded as nesting birds.
The
study area extended from Route 33 to the covered bridge west of
Revenge,
a distance of 7.5 miles. It was divided into convenient segments of
about one-half mile in length, each of which was transversed on foot
at least twice during each breeding season, sometimes
more often if peculiarities in weather or temperature seemed to be
inhibiting
bird movement or song. All of these trips were conducted during the
early morning
hours, usually between 6 A.M. and 9 A.M.
The
method used in taking the census was to include sight observations of
pairs
of birds, the occasional discovery of nests, observations of parent
birds
feeding their young and, most commonly, the counting of male
birds singing on territory. The latter method was certainly most
practical in counting
the more common species which were recognized breeding birds in the
valley.
In the case of rare nesting birds, including new species added to the
list of breeders,
every effort was made to substantiate evidence of breeding by finding
the nest,
observing the parents feeding the young, or the observation of
fledglings.
The
reliance placed on singing territorial males was felt to be more than
justified, especially so as
to limit interference in nesting activities that might occur from
searching for nests, and
it is a widely used technique in conducting breeding bird surveys.
Years of

Yarrow, Achillea
millefolium
experience in the
field made it possible for me to identify the songs of most birds
heard.
Even so, it is very likely that not all breeding birds were counted.
Many variables are possible
such as non-singing birds, the degree of a birds secretiveness, and
other behavioral characteristics.
The weather and the time of day, as already noted, were factors that
had to be taken
into consideration. There were other things to be considered,
including elements, known and unknown,
that could tilt the census numbers one way or another.
Just a few considerations on any given day might include the presence
of raptors, the ease or
difficulty in obtaining food, the ratios of dominant males to less
dominant ones, the presence
of non-breeding males and, possibly, females; wind and storm damage
done previous
to a count day and, of course, random chance.
