Thanks to today's visitors for their help spotting and IDing both raptor
and non-raptor species...in the morning we were joined by Rheinhold Pokraka
and Murray Larmour and later on by Bob Johnstone, Norm Holden and Gary
Pembleton.  Thanks also to Jim and Mary for the (as always) great
reports...and Bruce Parker for the Monarch Butterfly information.  

Winds were moderate to strong from the SSW for the day....often bringing
good flight of Osprey and Falcons along the cliff as they take advantage of
the dynamic lift created by the wind pushing up the cliff face. Temp got to
a high of 22 under mostly sunny skies as high pressure builds in over the

Raptor Observations:
The weekend was a hard act to follow. I guess the STRONG SSW WINDS pushed
all the wind surfers (read here Broadwings!!) farther north and only the
strong direct fliers courted the lake shore. After nearly 5600 Broadwings
yesterday...today ZILCH...not a single Broadwing was observed!

Total birds for the day was 128. The count included the typical species
that use lift along the cliff...Osprey (16), N. Harrier (16), Kestrel (90)
and a single Peregrine. The PG was a new bird (probably female) as it was
much larger than the mini model (likely a male) that's been harassing
everything along the lake for the past week.


Local Eagles and TV’s were up early and the legion of Gulls was a bit
annoying when trying to spot the actual raptor migrants.

Non-raptor Observations:
In the avian department, we had a paltry 7 species of Warbler today,
although among those were numerous Magnolias and Redstarts and an adult
male Wilson's in addition to Cape May, Black & white, Ovenbird and Common
Yellowthroat.  In the same area with the warblers were singles of
Philadelphia and Warbling Vireo and several Red-eyed.  As well a
Ruby-crowned Kinglet was noted sharing a tire-rut bird bath with several


Also seen today were Swainson's Thrush and a Veery, a lone Chimney Swift,
4 Common Loons, 2 Great Blue Herons, a Least Flycatcher, and 3 or 4 Tufted
Titmice were scolding this observer along with a mob of Chickadees at the
entrance to the woods. 


The bean field in front of  the mound continues to provide cover for
numerous Song Sparrows and Indigo Buntings.

Although we didn't specifically count Monarchs from the mound (too busy
counting AKs!) we did notice a good movement of Monarchs today and Bruce
managed to tag and weigh 30 over a 3-hour period.  As well, we noticed a
few "mini" roosts in various locations this morning; for example, about a
dozen Monarchs were roosting on a tree at the mound early this morning when
Jim arrived (about 6:45 EST).   Bruce also noted that many were seen
nectaring today, as opposed to blasting through as they have been on some
other days in the past week.

More moderate to strong SW winds predicted again tomorrow...so a similar
flight to today is a good possibility.
