Visitors:
Thanks to all of the observers listed above for staring at a mostly clear
sky all day. Also thanks to Joe and Lillie Luongo and Bobbye Sandahl for
their help, along with others whose names I failed to get.
We were so busy that I didn't pay much attention to the hikers and
sightseers, but there were quite a few on this relatively nice day,
although they didn't stay on the tower very long because of the chilly
wind.


Weather:
Cooler temps (57-72 F) than yesterday, moderate to low humidity. A light
haze left all regular landmarks visible.Winds from the NW to WNW were
stiffer than predicted, with frequent gusts of 12 to 16 mph. The only
clouds were around the periphery.
Raptor Observations:
A good, solid count after 2 days of bupkis. A pleasantly surprising number
of Bald Eagles passed through, including one loose group of 8. There were
no really big kettles of Broad-wings (6, 15, 5, 11, 5, 6, 5, 8, 9, 20, 6,
8, 6, 10, 8, 10, 10, 5 & 11) but birds kept moving through steadily after
9:00 am EST. Many of the birds were distant or very high - tough spotting
with few clouds to help.

Non-migrating raptors: Black Vulture-1, TV-6 (maybe more), Bald Eagle-5,
Red-shoulder-2, Red-tail-4

In celebration of our 50th anniversary year on Wachusett, here's a look
back at events on this date: In 1985, the 22nd largest Broad-wing flight
(4,842), 15th largest
Sharp-shin flight (108) and 20th largest daily count of all raptors (5,050)
in Wachusett Mt history

In 2001, no migrating raptors were counted. Authorities evacuated the
summit, fearing that the communications equipment there might be harmed
after the hijacking and crashing of 4 airliners by terrorists.

In 2017, Rod Chase wrote:
Up until 2pm our hourly counts ranged from 45 to 451. Most kettles formed
and quickly blew apart. Then at 3pm the skies filled with BW's in huge
peels and groups of 250, 370, 515, 650 with a steady supply of smaller
groups high and low! 2700+ BW's in a 1/2 hr. stretch in middle of hour;
3148 birds for the hour and a most beautiful kettle near the end from
ground to clouds in the west!! In the last hour: not one bird of any kind
in the sky; there was a perched Eastern phoebe ... Counter: Rod Chase.
Observers: Paul Roberts, Dave Brown, Kevin Ryan, Mark
Morris, Bill Rasku, Colleen Tank, Bill LaFleche, Christie Restell, Susan
Williamson, Ursula and Dave Goodine, George Cove, Mike Beath, Steve
Farrell, Mark Milnamow, Joseph Drega, Marty McNamara, Steve and Kathy
Olson. (Eric�s note: 4,894 Broad-wings counted, 21st largest in Wachusett
Mt history; 4,935 total raptors, 22nd largest daily count)
Non-raptor Observations:
Blue Jay-1, Comm Raven-19 (all in one group), Cedar WW-5, Gr Catbird-1, D-E
Junco-1, E Towhee-2.

Predictions:
Another cool start to the morning with temps in the upper 50's to lower
70's, with low humidity. Clear skies in the morning and partly cloudy after
noon, with 5-7 mph winds from the SE to SSW. The birds are moving well
now, so mild southerly winds shouldn't be much of an impediment.
