Last night’s forecast for high temps and humidex today was right on.  Wind
direction was SW and the highest wind speed we experienced today was 10 km
/ hr, so very little breeze came by the observation knoll.  The heat was
compounded by the lack of shade on the knoll except for a couple of hours
following the noon hour.  Nevertheless, both raptors and observers were on
hand and the pace was steady until the last hour.  Cloud cover was variable
throughout the day and folks on the knoll even heard some thunder around
mid-day.  By 2:00 PM, there were clouds on the horizons, but above and in
front of observers was clear, cerulean blue.  

Raptor Observations:
We tallied a total of 134 raptors today composed of 5 species.  These were
Osprey (3), Northern Harrier (13), Sharp-shinned Hawk (22), American
Kestrel (95), Merlin (1).  The only Merlin came through in the last hour,
taking time out to chase a local Bald Eagle seen in “the bite”, an opening
in the line of willows that runs north starting right at the cliff’s edge. 
After that quick diversion, the Merlin got back on course and zoomed
westward along the cliff, over the treeline and out of sight.  The AKs were
fairly steady throughout the day but peaked during the 11 o’clock hour at
24, then dropped off to just 3 between 12 and 1; with numbers rising again
through the last 2 hours of the watch.
Bald Eagles cruised back and forth very low at the cliff throughout the
watch.  Observers are beginning to recognize individuals, having seen them
so often in the past few days.

Non-raptor Observations:
Monarch Butterflies were on the move again today with 33 counted between
7:30 AM and 2:00 PM.  
On the avian front, observers reported a total of 3 New Species today,
starting with Shorebirds; From the observation knoll, observers spotted a
large shorebird as it flew east along the cliff, and was identified by
Derek as a Whimbrel.  The Whimbrel flew down below the cliff but not before
giving the observers a really good view.  Shortly thereafter, a
Black-Bellied Plover landed in the field!  Around mid-day, the “heritage”
mulberry tree was a very active spot with numerous warblers, including the
third New Species for this season which was a Black-throated Green Warbler.
 Other warbler species were Magnolia, Cape May, Blackpoll, Canada, Black &
White , Tennessee Warblers plus Am. Redstart and Ovenbird.  In addition,
birders in that location had a great view of a male Scarlett Tanager.  
Other species seen today included Chimney Swift, Baltimore Oriole,
Swainson’s Thrush, Rose-breasted Grosbeak, Ruby-throated Hummingbird, Gray
Catbird, Eastern Towhee, Red-eyed and Warbling Vireos, Red-breasted and
Downy Woodpeckers, House Wren, Least Flycatcher and Great Crested
Rodents were also represented today, as a groundhog provided good looks for
folks on the knoll.  

A few clouds are expected overnight with tomorrow’s weather much like
today’s except that highs are expected to reach and exceed 30 degrees
Celsius by 12:00 PM.  Winds will be a bit stronger than today reaching 18
to 20 km / hr. There is the possibility of a thunder shower tomorrow
evening and again Tuesday morning with very light winds from the N / NE,
shifting late morning to, once again, a southerly flow.  This isn’t a great
forecast for migrating raptors, but the birds kept coming through yesterday
and today; numbers aren’t likely to be any higher than the past two days’
