Visitors:
We welcome visitors to our site and are very willing to share migration
information, photography and ID tips with them. We have cards and
pamphlets, so come and talk to us. However, during times of high traffic,
requiring extra focus and concentration, we would respectfully ask that
everyone use their indoor voices and allow us to fulfill our mission to the
best of our abilities. Thank you.
Weather:
Today was the first day of Hawk Fest at Lake Erie Metropark. Itâs always
on the third weekend of September in the hopes that the broadwings will
provide the awe-inspiring displays for which they are known. Although they
were present in some numbers in the morning, the winds were not in our
favor as they vacillated, then picked up strength from a direction that
pushes them into the hazy sky to the north. Some kettles were visible to
our visitors but it was not the show we wished to present. The clouds did
fill in as predicted, with thin icy cirrus at first, becoming denser with
cumulus, and even alto cumulus later on. Temperatures were near the
seventy-degree mark at their height, and with the cooling breeze, albeit
not our favored wind, it was another benign fall day. The barometer was
falling as a rain system approaches, but it appears to be less threatening
as the blue, wet portion of the graph is shrinking. Although we did have a
fairly decent day, we did reach a point of diminishing returns at the end
of the normal watch hours and, unlike the last three days, no OT was deemed
necessary.
Raptor Observations:
Broadwings, despite their diminished numbers, still led the parade today
with 2153 of them in stealth mode, as per usual, most of them in the
morning hours. The sharp-shinned hawks continue to impress with 544 of them
coming at us from all angles. American kestrels came by in twos and threes,
totaling seventy-three at the end of the day. One merlin and one peregrine
completed the falcon hat-trick. Northern harriers are nearly at last
Septemberâs total only halfway through the month. Today we counted
twenty-five. Turkey vultures are holding back until October before they
begin in earnest, today only thirty-five were noted. Four bald eagles and
three ospreys pumped by; one red-tailed hawk was also tallied.
Non-raptor Observations:
A pair of sandhill cranes have been seen several times along the entrance
road to the park. Today we could see long strings of migrating ducks off in
the eastern sky. Mallards and some blue-winged teal were seen close by. A
single pied-billed grebe is spotted on occasion in the slip, but usually,
we see more of them in a normal season. The cormorants are still seen in
their follow the leader lines low over the water but also, migrating groups
can be seen. The kingfisher continues to be active. Some swallows and
swifts were seen today but not in the large numbers that we have become
accustomed to in seasons past.
Predictions:
Well, it should be cloudy. That is probably the only certainty for
tomorrow. The winds again will probably be a nothing-burger since their
predicted speeds are so low that they will be variable once more. There is
some NNE predicted in the morning but those predictions have meant little
the last few days. Perhaps we will get those winds and those in attendance
at the Hawk Fest will be treated to the show they deserve. Itâs certainly
better than the southerly winds we ended up with today. Sharpies, kestrels
and harriers should continue to pour into the country, ignoring the delays
on the Ambassador Bridge.
