There was a decent crowd (~20 people) for much of the day, especially after
the Fred Kirn memorial and kiosk dedication, which took place right next to
the count site.

There was partial cloud cover all day, at around 25 percent. We watched a
couple of uniquely long, dark, and thin clouds materialize as if a knife
slowly cut a line through the sky. Winds were from the east and south, and
almost always weak down at our level.

Raptor Observations:
We had more Sharp-shinned Hawks fly over today (154) than on any other day
yet this season. We also matched our best Northern Harrier day, at 20
individuals. Few Broad-winged Hawks flew by within sight. We suspect that
many of the Broad-wings may have flown to the north of us, as winds were
southerly. Further, we spotted a small kettle (a swirling body of hawks,
soaring) far to the north.

Non-raptor Observations:
While looking through the sky, one (and maybe only one!, i.e. the report
writer) can sometimes momentarily mistake the fluttering wings of a
butterfly for the fluttering wing beats of a distant Sharp-shinned Hawk.
Many Monarch butterflies were spotted today, as the gentle, south easterly
winds appeared to be ideal to help ease them on their way south. When life
jerks us around, it may help to think of the tiny, migratory Monarch
butterflies which have so far survived in a windy world! And try to
remember to appreciate favorable wind!!

Scattered rain and thunderstorms are predicted all day tomorrow, and winds
from the west, which will likely not be conditions ideal for much movement.
Though we shall see...
