Total observation time: 6 hours

Official Counter: Rod Chase

Observers: Bill Rasku, Ted Mara

Observers: Ted Mara and Bill Rasku enjoyed the 1st hour and I arrived for
the slightly better 2nd. Movement died down after that but we were elated
about this August flight as well as the antics of the local birds.
Visitors: The flow of hikers and a few drivers was slow and we frequently
had only 1 or 2 small groups on the observation deck.
This made for nice chats and good question/answer periods. Maybe 80 total

Temp was 73F/23C at 9am and climbed steadily thru the day to 77/25. Winds
also fairly uniform: 5-10mph/8-16kph during the 1st hour then 3-5mph/5-8kph
with occ. gusts to 8m/13k until the last hour which was steadier at
Wind direction started from NW and varied to WNW and back for hours before
shifting to West for last hour.
Visibility approx. 5mi/8km at start but by 2nd hour mist burned off ...
leaving the smoke so visibility was about 8mi/13km for rest of day.
Overcast 20% at start slowly increased to 50% by end of watch.

Raptor Observations:
Broad-winged hawks created the big rush early with 23 and 21 migrating in
the 1st two hours; then only 3 more for the rest of the day.
2 Ospreys passed to east & then SW in the 2nd hour as well as 'The Migrant
of the Day': a juv. male Northern Harrier was spotted in the NE by Ted and
we followed his darkish form thru to the SW.
The 11am hr. had 1 BW and then 2 adult Bald Eagles at 11:57went thru at
same time: 1 to W and 1 further out to SW.
No migrants from 12-1pm; 2 BW's passed from 1-2pm but the hour was great
due to "The Locals of the Day!" One and then a second Merlin appeared and
repeatedly challenged a Peregrine who was, apparently, flying over their
territory. PG was nonchalant at first but, once his temper flared, artfully
drove the Merlins repeatedly down to the treetops.
As the peregrine disappeared towards Worcester the Merlins disappeared
nearby below the treetops. They probably thought they'd won the dispute? It
was a memorable show!
Last hour had 2 OS moving together from ESE to SW.
Locals: 2 appearances of the local Cooper's Hawk (or
Hawks?) Also 8 TV's; 4 BW's; 1 each imm. and adult BE in 1st hr; 1 BE adult
1:45pm on E/SE side; and 8 imm. RT's and 1 adult.

Non-raptor Observations:
Local: 2 appearances of the local Cooper's Hawk (or
Hawks?) Also 8 TV's; 4 BW's; 1 each imm. and adult BE in
1st hr; 1 BE adult 1:45pm on E/SE side; and 8 imm. RT's
and 1 adult

Mostly sunny, with a high near 92. West wind 7 to 11 mph
with gusts as high as 24 mph. Winds and heat's not ideal
but, of course, one never knows for sure.
