Visitors:
We are still dealing with the residue of the Covid 19 situation. The
workers at the site will be in an enclosed area that is designed for four
people only. We still love to interact and share our love of hawk watching
with visitors. Feel free to ask questions and look over our shoulders to
help you follow the birds. Watch the weather for favorable forecasts as the
birds are predictable to some degree based on weather situations.
One other thing of note this year; the boat-launch bathroom building has
been shut down for the foreseeable future due to plumbing issues. There are
Porta-Johns in the parking lot should you require them.



Weather:
Another day of restless skies with frequent changes in appearance. Half a
sky of foreboding dark morning clouds dropping rain out over the lake
greeted us, it soon changed to cumulus laden chamber of commerce skies,
then to clear blue, and finally the appearance of high icy cirrus clouds
forecast rain to come tomorrow. Against this backdrop an epic struggle was
taking place around us. The Battle of Pelennor Fields was taking place in
miniature as spiders and mysterious flea-like creatures squared off in
mortal combat. Had we stayed longer we might have been fully cocooned in
silk since they had built functioning webs in our camera hoods and on the
scope tripods. The minute but plentiful mystery-bug combatants sought
refuge in the small end of our binoculars and scopes causing some
consternation and occasional ocular discomfit. During all this, the winds
were up and down in strength and moved from W to S throughout the day. The
final S direction moved the flight line off to the north after a fairly
decent day. The morning and early afternoon winds were moderate in strength
and did not affect the flight as much. Temperatures were comfortable as
they rose to seventy degrees from sixties in the morning. The barometer
moved very little but hung around thirty inches most of the day dropping a
little at the end.

Raptor Observations:
Although the viewing conditions were not perfect, with haze and high
humidity causing some issues, it was good enough to see most of the birds
without the gauze effect that we have been dealing with lately. The turkey
vultures were visible today as they moved most of the day. We should be
seeing thousands at this time of year and we finally cracked that nut today
with two thousand, three hundred and ninety black bombers floating by. It
was a little curious that when the vultures took a break, the small birds
seemed to come in droves as sharpies and kestrels came in big numbers. We
ended with one hundred and fifty-two sharp-shins and seventy-three
kestrels. Even these birds were pushed to the north at the end of the day.
We finally got a few buteos today as red-tailed hawks were gliding by,
totaling fifteen in all. We had four merlins today and barely made our
falcon hat trick as a distant peregrine was noticed diving on the lone
red-shouldered hawk as it flew by. We also had three northern harriers high
overhead today. Our intrepid spotter and photographer, Mark Hainen, made a
great discovery on the way home today. He noticed that one of those things
was not like the other and got a shot of a Swainson’s hawk in with the
migrating turkey vultures. Neither of the neighboring hawk watches caught
that bird but most of the vultures were seen at some distance, especially
in the final hours with gull kettles providing cover.

Non-raptor Observations:
Blue jays continue to flood the skies with large flocks passing though.
More blackbirds and starling flocks are being seen. One way to locate
sharpies in the morning hours is to look under a small “starling ball”
as they often gather over an accipiter to mark its presence. Large
murmurations are sometimes seen over Canada. Caspian terns are still here
but their numbers are small. Monarchs numbered thirty-five today. Gulls
were up in significant numbers in kettles hawking insects.

Predictions:
Tomorrow may be a day of two parts. Rain looks probable in the later hours
but the morning may allow us some time to observe the sky, dark though it
may be. Winds will be from the southern quadrant although moderate in
strength. The barometer will be slowly dropping and take a plunge the next
day as more rain is forecast for Friday. I think the best chance for
movement may be Saturday and Sunday when the barometer rebounds after this
wet patch moves through. The winds look more favorable on those days.
