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:
I always say that you have to pay your dues in hawk-watching to receive the
benefits. Yesterday was a dues paying day, today was benefits day. The wind
was moderate to begin with but it began to increase, on an opposite
trajectory to the barometric pressure which fell to possibly our lowest
reading of the season at 29.63 inches. Winds were very favorable at first,
out of the ENE, but then went E and grew to comfortably over ten mph,
relentlessly tightening the skin on our faces as the day progressed. Since
tomorrow looks to be a rain-out, the birds were making the best of the
window of opportunity to exit before it arrived. The sky started off
similar to the last prelude to rain that we had with a solar halo complete
with a sun dog accent making for an attractive morning sky. The clouds took
their time filling in with early wispy maresâ tails splashed on a bright
blue background. Contrails from the planes high overhead spread widely to
create their own form of marker for us to use in locating birds. The late
afternoon hours were filled with darker stratus clouds that looked as if
the rain might arrive ahead of its appointed hour.
Raptor Observations:
It was Birdapalooza for the first few crazy hours as the birds came in big
numbers but in many different flight lines. It might have been better if we
each had three eyes to use. As the wind went more easterly and grew in
strength, some of the action ended up over the lake at a distance which
made it more difficult to record. The turkey vultures led the way of
course, with five thousand, three hundred and fifty specimens noted. The
TVs usually drag along the buteos with them and today was no exception with
five hundred and seventy-six red-tailed hawks and one hundred and
thirty-six red-shouldered hawks making the count. One bald eagle was
counted and five golden eagles flew by on their own individual courses. The
sharp-shins may have been affected by the strength of the wind as they are
normally buffeted even in moderate winds; we notched twenty birds today.
Only three of their bigger brothers, the Cooperâs hawk, were counted.
Another bird that suffers from exposure to high winds, the American
kestrel, was noticeably absent today with only two counted; no other
falcons were seen. Four northern harriers took advantage of the tail wind
to head south. Our first rough-legged hawk of the season made a brief
appearance racing by on the winds as most birds were. They moved so rapidly
that it was difficult to relocate them if you took your eyes off for a
moment.
Non-raptor Observations:
The crows were on the move today with many thousands observed. They took a
distant line over the lake at times making an exact count difficult. It was
difficult to pay much attention to other species today as we were occupied
most of the day with raptors. A flock of Forsterâs terns, consisting of
about twenty plus birds made a brief appearance. The high winds kept most
of the avian flak down out of sight so our vision was not obscured today.
Predictions:
Tomorrow, hmmm, letâs seeâ¦er, rain. Raindrops will be as numerous as
the birds were today. Saturday will be iffy early as showers may continue
in the morning hours. The barometer will start to rebound but the day
should be cloudy all day. Winds will continue to be fairly strong on
Saturday and from a good direction but it remains to be seen if the birds
will move that close to the passing storm. Sunday looks more promising.
