Official Counter: Chris Eddy

Observers: Alicia Carrillo, Bill Rasku, Eric Mueller, Jim Kirchhoffer,
Joanne Hart, John Edmondson, Kim Hewitt, Marilyn Cugini,
Steve Smith, Ted Purcell, Tom Gottschang

Visitors:
We had a very nice turnout of observers today. Many thanks to both those
listed above, and to Rose Stewart, Andrew Leal, John Byers, Bobbey Samdahl
and John Sisk. With the gloomy weather conditions, there were relatively
few hikers and sightseers.


Weather:
After 3 days of rain, there was plenty of moisture left in the air and it
manifested itself as low clouds that covered the summit until 9:30 EST, and
that never rose high enough to uncover the top 1/3 of Mt Monadnock. Small
sunlit patches appeared here and there on the landscape, but there appeared
to be too little sunshine to generate much of any thermal lift. Visibility
was limited to the Boston skyline, the southern NH hills as far east as the
Uncanoonucks, and Mt Grace to the WNW. Winds were from the NNW to NW at 4-7
mph with some gusts to 12 mph in the morning. Temps rose from 55 to 64 F.

Raptor Observations:
The low cloud cover kept the birds low in general, although we lost some
birds that climbed into the cloud cover. Bill spotted one kettle of 10
Broad-wings that popped up to our south. Northern Harriers didn't seem to
mind the relative lack of lift, but we think that if the cloud cover had
risen normally, we would have seen many more birds migrating. Turkey
Vultures continue to move through in small numbers. Some unidentified
raptors passed by at great distance.

Non-migrating raptors: TV-4, Bald Eagle-2, Red-tail-1, Amer Kestrel-1.

In celebration of our 50th anniversary year on Wachusett, here's a look
back at events on this date in previous years:
In 2008, Steve Olson wrote:
An odd day for the birds to get lift. A few thermals but not many. When the
sun came out, a few birds flew. Birds had been rained on for three days and
were probably drying out. Most of the birds were very far out and account
for the UR category. (Eric�s note: 31 total raptors including 8 Unknown
Raptors. This day sounds quite like today.)

In 2014, the 3rd highest daily count of Peregrine Falcons (6) in Wachusett
Mt history, tied with 9/16/17.

In 2021, the 5th highest daily count of American Kestrels (26) in Wachusett
Mt history, tied with 9/10/95 and 9/22/18.

In 2022, the highest daily count ever of Cooper�s Hawks (26) in Wachusett
Mt history.

Non-raptor Observations:
Non-raptors: D-C Cormorant-1, Hairy WP-1, Blue Jay-11 (9 migrating), Comm
Raven-7, R-C Kinglet-1, B-C Chickadee-2, Gray Catbird-2, R-E Vireo-1, D-E
Junco-8, Blackpoll Warb-1, E Towhee-3 (looks like they bred successfully.)

Predictions:
Different weather apps disagree with each other, but we're expecting more
sunshine than today in the morning, with increased cloudiness in the
afternoon. Temperatures similar to today with a high around 65-66 F, and
slightly lower humidity. Winds are expected to be light at 3-5 mph,
starting from the NW in the morning and moving to WSW by the early
afternoon. The key to the migration will be the height of the cloud base
and the actual amount of sunshine in the morning. Fingers crossed...
