Weather:
A vwry pleasant day overall, with very little cloud cover to start, NE
winds and increasing cloud as the day went on.  However, we didn't get rain
until the very end of the 1:00 hour, and that was only a sprinkle.  Cloud
cover was 100% by then, though, and for mid-afternoon, it was pretty dark. 
Then at the top of the hour, it looked like the cloud was clearing again,
just enough to let a few last-minute migrants blow through, then the rain
began, this time in earnest. Temperatures ranged from 14 C. to 24 C., then
slid back to 22 degrees Celsius. 

Raptor Observations:
What a day!  We tallied 633 birds today composed of 10 species including
Osprey (8), Bald Eagle (7), Northern Harrier (12), Sharp-shinned Hawks
(113), Cooper's Hawk (2), Broad-winged Hawk (382), Red-tailed Hawk (7),
American Kestrel (98), Merlin (2) and Peregrine Falcon (2).  Almost all of
the birds were very high up, a result of the easterly component of today's
wind, although in the last hour, the flight began to descend to lower
altitudes, making viewing much easier.  We had a few sprinkles of rain
right at the end of the hour, and clouds had thickened making it very dark
around 2:00 PM, so we decided to shut things down.  Then suddenly, several
raptors decided to make a last dash across the field.  Another half hour's
watch yielded 30 more birds, some right at eye level and even the last 6
AKs were flying about halfway up the field instead of their usual route at
this time of the year which is along the cliff.  



Non-raptor Observations:
Things were very quiet along the roadside and in the woods.  One observer
ventured along the pond path this afternoon, but the only sighting there
was an immature Bald Eagle, plus a few Monarch Butterflies.  

Highlights from today were Great Blue Heron, 15 Wild Turkeys in the field
just north of the ravine, a raucous Caspian Tern, Red-eyed and Philadelphia
Vireo in the ravine, Tree Swallows plus Am. Goldfinches flying westward in
flocks across the field and a Pileated  Woodpecker that flew across the
knoll. Eastern Bluebirds were seen on Fairview Rd on the way to the cliff
this morning early (just north of Sparta Ln), and later, Bluebirds were
heard calling near the observation knoll, probably in the field just west
of the parking area.  

Predictions:
Northerly winds are expected throughout the weekend with considerable cloud
to start on Saturday morning, brightening somewhat by afternoon.  With the
wind speed predicted to be 15 tp 20 km / hr, and mainly from the north, it
should be a great weekend for hawkwatching, especially for those
Broadwings!
