We had a small group join us today, with a maximum of ten guests at one
time. Apparently, many people knew that the winds would not be favorable
for Broad-winged Hawks to fly over us today!

The cloud cover increased from virtually none when we arrived to about 80
percent by 11. For the rest of the day the cloud cover held steady. The
wind was mostly very weak, coming primarily from from the east, and
sometimes the south. 

Raptor Observations:
We had our best Sharp-shinned Hawk day of the season, with peak activity
between 9 and 1, and 322 birds counted total. All of the Broad-winged
Hawks spotted today were to the north of us, or moving that way. After
spotting a couple sizable groups at around 10, we spent the rest of the day
counting a steady and slow trickle of distant 'Broads', streaming along the
northern tree-line. Several kestrels and harriers were also spotted today. 

Non-raptor Observations:
We counted 85 Monarch butterflies, and 973 Blue Jays. The latter can be
confused with Broad-wings, for an instant, at a distance! Unlike
Broad-winged Hawks, Blue Jays flap constantly, and seem to be less equally
spaced than are streaming Broad-winged Hawks. Red-winged Blackbirds were
also migrating today, and we noted 50. Ruby-throated Hummingbirds are still
moving south, too.

The Weather Channel says that tomorrow will likely be mostly sunny, with
winds from the south and west. At the very least, we will likely have
Sharpies flying over us tomorrow.
