Visitors:
We welcome visitors to our site as we are eager to share the joys of hawk
watching with one and all. Although there may be times in which we are all
very busy and need alone-time to concentrate, those are the times that are
most enjoyable for visitors as the skies are filled with migrating raptors.

Weather:
“The voice of the turtle is heard in our land”, as the late, great
Ernie Harwell would recite every year, opening a new season for the Detroit
Tigers. Today we opened a new season of hawk counting at the Lake Erie
Metro Park, and staying in the baseball idiom, riding on the shoulders of a
northerly starting wind, we won the opening-day game. The past few years
have been a coin toss as to whether we would sit through a blazing hot
remnant of summer, or hopefully, have a hint-of-fall day with favorable
winds. We lucked out this year with the latter. The winds did take quite a
swing around the compass, starting north and ending southeast, probably
hurting our totals. The wind strength was in our sweet spot of seven to
nine mph. As the wind was passing through the easterly stage, the
convective cumulus clouds that form on the edge of the lake became more
prominent in the sky over us, darkening on the bottom to an almost ominous
shade of blue-gray, although I don’t think any of us actually felt
threatened. Temperatures reached a peak of seventy-six degrees, which was
tempered in our location as the wind blew off the lake in the afternoon
hours. A reminder that when hawk-watching, you should keep two more layers
than you think necessary in the car just as best practice. The barometer is
beginning a gradual decline which should culminate in a rainy period in a
couple of days. It stayed in the 30.2” range today but the downward trend
had begun by late afternoon. It was a pleasant Labor Day, made more
pleasant by the reunion with old friends, all of whom had managed to
suppress the memories of more malign days sitting for hours in freezing
winds with little to show for it.

Raptor Observations:
It’s always good to see broadwings on the first day as the waft their way
south, taking their time at a pace we wish we could emulate in our own
frenetic lives. We managed to put twenty-two of them on the clicker today,
usually two or three at a time. Seven red-tails flew over, although we are
a little wary that there may be locals patrolling their territories, as
some were headed in the wrong direction and were not counted. Three
kestrels scooted by and there may have been a fourth as we got a brief
glimpse of another small falcon with not enough time to determine whether
kestrel or merlin. The kestrels appeared dark today due to lighting
conditions and that is usually an indication of merlin so it remained an
Unknown Falcon. We had one harrier in the late afternoon. We did see bald
eagles and osprey but those were deemed local and not counted. Cooper’s
hawks were present, but they were seen multiple times in the usual haunts
for our local birds.

Non-raptor Observations:
The non-raptor side of things was interesting. We were greeted by the sight
of hundreds of purple martins amassed in the dead trees close to the hawk
watch. They seem to disburse during the day as is their wont, but swifts
and swallows of various persuasions took their place, although in smaller
numbers. Warblers were reported on the trails. Cormorants are there in some
numbers but not the large conglomerations that seem to form a little later
in the season. A kingfisher made a few appearances. Both a great blue heron
and great egret flew by. The largest wingspans we saw belonged to a flight
of approximately forty-five American white pelicans headed north out over
the lake. Pied-billed grebes, a common sighting at the watch, were also
noted. Three mute swans made a cameo appearance. A yellow -shafted northern
flicker undulated over. Today was a very good day for monarch butterflies
as we notched 129 of them.

Predictions:
Tomorrow has a favorable wind… during the early morning predawn hours.
Unfortunately, when we begin the watch, the wind will shift to the
southeast side of things and grow in strength, staying in the five to eight
mph range. Usually, this carries the wind-surfing birds (broadwings) to the
north of us. Although we generally don’t expect large numbers of them
this early, the premature evacuators are flying already in twos and threes
as we witnessed today.  Sunny skies are expected with temps about the same
as today. The barometer will be falling, crossing the 30-inch barrier late
in the afternoon.
