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:
Back in the saddle again. After a day off, due to significant rainfall, we
were back at it. The wind was NNW all day, and a persistent wind it was. It
peaked in midafternoon at fifteen mph, with very healthy gusts, but fell a
little towards day’s end. Curiously, this wind blew the water out of our
end of the lake, perhaps Port Clinton, OH is flooded today, but a sizable
drop in water level is usually associated with a SW wind. Temperatures
neared the mid-fifty range but felt about five degrees cooler. The
barometer was slowly dropping all day. Skies were a little bit of this and
a lot of that. “This” being a blue sky with little cloud cover,
“that” being a leaden stratus layer that gave one a feeling of winter
yet to come. A light rain did finally fall as we departed after spending
extra time counting turkey vultures. 

Raptor Observations:
Turkey vultures took up where they left off, but with more lightly
populated, slower flows today. The winds scattered the flight lines all
over the sky as if they had a multiple-choice question before them with no
wrong answers. In the afternoon hours they picked up the pace a little and
we finished with a total of 4,349. Sharp-shins were the other active mover
today with 233. None of them looked comfortable as they battled their way
into the wind oscillating like yo-yos on an invisible string. Red-tailed
hawks made a respectable showing with thirty of them making the scene. Five
red-shouldered hawks joined them on the journey. Three northern harriers
made the trip today. Peregrine falcons easily cut through the wind, four of
them were counted today. The kestrels were almost MIA with only four being
seen. One broad-winged hawk, maybe the last one, was tallied today. Our
local osprey was still present but not counted. One pleasant surprise today
was our first rough-legged hawk of the season, a light morph. These birds
have been scarce at our site the last two years and we are hoping for a
better count this year.

Non-raptor Observations:
We had another pleasant surprise this afternoon when we spotted a little
gull out by the entrance buoys. We had one stay for a couple of weeks last
year. This one seemed to prefer the company of a few Bonaparte’s gulls
and common terns. The marsh was full of water this morning when we drove in
but all mud flats when we departed due to the drop in the water level of
the lake. The kinglets seem to have arrived in the hedges behind us. A pair
of common mergansers were seen flying out of Dodge this afternoon. Plenty
of swallows are still at work cleaning the skies with a lot of help from
the gulls; there is a lot of biomass in the skies above us. Our first
murders of crows started to pass today, blue jays are still flying but in
diminished numbers.

Predictions:
Another ditto day tomorrow. Winds from the NNW around the ten-mph range,
lots of cloud cover, just under twenty percent chance of rain, barometer
rising slightly, with temperatures in the same zip code as today.
Hopefully, the birds will turn up in the same numbers.
