CHIMNEY ROCK:
THE LITTLE KNOWN HAWK WATCH
It was early autumn of 1990. I had
just left my position as naturalist at
Scherman/Hoffman Sanctuaries to
pursue a master's degree and was looking
forward to spending free time afield with
my binoculars. I made all kinds of plans
to "bird" and hawk watch in Cape May
and Sandy Hook, as well as Montclair
and Raccoon Ridge. It was while I was
piecing together my proposed birding and
hawk watching trips, that a friend of
mine, Henry Kielblock, called and asked
if I was interested in doing a little
"birding"? As most people who know
me will tell you, this is the same as
asking me whether or not I would like to
win a $10 million lottery. I asked Henry
if he wanted to head up to Montclair to
do some hawk-watching. But Henry
didn't seem overly enthused about the
thirty-five mile drive up there from
Somerville. Yet he was still anxious to
see some hawks, It was then that the
magical words came from Henry's
mouth, "Hey Chris, you ever been up to
Chimney Rock to hawk watch?"
"Chimney what?" I asked. "Chimney
Rock, ya' know, over in Martinsville,"
Henry replied.
When I explained to him that I had
never even heard of it, he told me that he
would pick me up in a half hour to go
there.
When we arrived, I was amazed at the
extraordinary view I was offered from
the lookout, which is approximately 400
feet up on a bluff at the end of the first
Watchung ridge. I could see nearly
twenty miles out into the distance, and
immediately started playing the "name
the landmark game," just as one does
when he goes to the top of the Empire
State Building for the first time.
"Look, Henry, isn't that the 3M factory
over in the Sourlands Preservation in
Belle Mead? And what about that over
there, that looks like the Holiday Inn
over in Somerset!"
I was really getting into this. But, I had
not come up here to appreciate the view.
I was here to see hawks. Within minutes
of redirecting our binoculars from the
scenery to the heavens, a pair of
"sharpies," flew over us heading in a
southwesterly direction, making them our
first two official migrant raptors of that
early autumn. Soon, many more were
passing over us, mixed with kestrels and
the occasional osprey. By the end of our
five-hour visit, we had chalked up some
fifty-three birds; not bad for the seventh
day of September at a hawk watch I had
never even heard of. Along with the
migrants, we were overly impressed with
the four black vultures, that mixed in
with the many resident turkey vultures,
circling over our heads for most of the
day. On the way home, I thought, "Well,
maybe it was just an accident; it couldn't
possibly be that good and be just ten
minutes from my house."
I decided to go back up bright and
early the next day. When I arrived, the
wooded lot surrounding Chimney Rock
was jammed full of warblers. Within an
hour I had counted fourteen species, and
I had not even made it out to the actual
hawk watch yet! I knew there had been a
small weather front from the northwest
that had pushed through within the last
forty-eight hours, but this was amazing!
Before my eyes in one field of view were
three black-throated blue warblers, two
black-throated greens, and two oven-
birds. I began to wonder now if I might
have found a truly special place. This
was soon answered when I finally made
it out to the lookout. The hawks were
really moving for such an early September
day. Sharp-shinneds, in particular,
were exhibiting extremely good numbers,
not to mention the merlin who flew
directly out of the woodland from where
I had come and proceeded to do a beeline
for my head, veering to avoid me only at
the last minute with a most impressive
mid-air 90-degree angle turn.
I was having a great time. Better than I
had ever had at any other hawk watch.
At first I didn't really know why I was so
enthusiastic about this site. Was it
because it was my first visit there and it
had the fresh appeal of a new place?
Maybe. But there was something else.
Gradually I began to realize what it was:
low-flying birds. Not just that typical
low-flying merlin, but the vast majority
of the birds passing over me were right
over my head; most were identifiable
without binoculars. Some people have
speculated that this is because Chimney
Rock is located near the western end of
the Watchung ridge, where the birds may
be descending in anticipation of changing
their flight course from a westerly direc-
tion to a southwesterly one.
Whatever it is, the low altitude flight
remained very consistent and rewarding,
especially so when later that day an
immature bald eagle passed over me at
no more than 80 feet, heading southwest.
I could literally see him looking back
down at me as if to say, "You ain't seen
nothing yet." He was right. By the end of
that following October, Henry, George
Hall, and I had logged three more of
these "low flying" bald eagles for a total
of four in a very limited amount of time
at the lookout, along with impressive
totals of all the other typical raptors.
During the next couple of months after
the watch at Chimney Rock, I thought
about just how good the raptor flight had
been, not to mention the warbler fallouts
that had occurred. With this in mind, I
decided that Chimney Rock was certainly
worthy of a "formal hawkwatch." So
after making the necessary arrangements
with the Somerset County Park Commission,
I prepared for the following fall.
When September 1991 arrived, I was
ready. Accompanied by a good number
of hawkwatching friends, plenty of free
time during the day, and a tolerance for
standing in one place by myself for long
periods of time, I set out to conquer the
hawks of Chimney Rock. But would the
numbers be anything like the year before?
Had 1990 just been a good year for
hawks along the western Watchung
ridge? I needed to know. Fifty-five
manned days later, (twenty days each in
September and October, and fifteen in
November), we know: It was not an
accident. By November 20, we had
logged 1495 sharp-shinneds, 525 kestrels,
198 ospreys, 10 peregrine falcons (in-
cluding 5 in one day), 10 bald eagles, and
4 golden eagles. We also had counted
approximately 9 percent of the total
broad-winged hawk flight that had passed
through New Jersey that fall. This is not
to mention the hordes of warblers and
other passerines that once again frequented
the vicinity of the lookout
throughout September and into October.
(See Spring 1992 issue of Records of New
Jersey Birds for totals of all individual
species recorded at the Chimney Rock
Hawk watch.)
When all the hawks had been tallied,
the total stood at 5,740. A number I
never really imagined possible. But then,
probably anything is possible at Chimney
Rock.
