With somewhat seasonable temperatures and fairly calm winds to start the
day, it is a great surprise so few people made their way to the platform to
take advantage of the morning before the rain. Nevertheless, 13 visitors
eventually found their way to the platform to ask questions with the

Autumn weather in New England is a lot like a mixed pack of craft brew from
your favorite local brewer. Across the season you can encounter everything
from light and crisp or wet and unfiltered to something darker and heavier.
Sometimes you can encounter all of these in the same day! Today’s weather
was a lot like this and it even included a few limited-edition one-offs.
Outside of snow, just about every type of fall weather was encountered or
viewed today from the platform. Overcast and gray, the air was still to
start, with maybe the slightest of a SE breeze bringing a rustling sound of
dried leaves to the observatory platform. Temperatures ranged from 3-11C
(37-52F) throughout the duration of the count and it remained very
seasonable without much wind. The threat of rain to the platform was
palpable all afternoon and reports of downpours nearby likely limited any
raptors from the platform even though it didn’t rain until sometime during
the last two hours of the day. Eventually, thick cloud cover, rain, and
even thunder pushed the counter from the platform and down the mountain. It
was perfect timing as within the half hour of making it into town the sky
was nighttime dark, lightening flashed, thunder roared, and pea-sized hail
coated the local roadways like the first slushy coating of snow.

Raptor Observations:
Due to the impending rain, the air felt and looked surprisingly thick and
hazy today. Even with visibility out for miles, the air was so thick and
dark it made scanning for low-flying raptors against the landscape
virtually impossible. With little to no wind to start, raptors were slow in
taking to the air and even then, were far from numerous. Three migrating
Northern Harriers (all adult females) bookended the day while a lone
Sharp-shinned Hawk (presumed adult male), found its way onto the data
sheet. A local immature Red-shouldered Hawk represented the closest raptor
to the platform today while distant Red-tailed Hawks continue their stint
around their favorite haunt of North Pack.

Non-raptor Observations:
Non-raptor avian highlights today included the following: Canada Goose
(85), Downy Woodpecker (1), Black-capped Chickadee (8), Red-breasted
Nuthatch (1), Golden-crowned Kinglet (2), Hermit Thrush (1), Pine Siskin
(3), and Yellow-rumped Warbler (3). Fall, is really setting in across the
mountain top and is starting to show the precursors of the winter to come
in the birds we are seeing consistently.

At this moment, showers are predicted during the first part of tomorrow’s
count and even if they end up not being a big threat, any associated clouds
from that system may limit visibility. Fortunately, there should be some
afternoon clearing. Temperatures are predicted to be in the 40s (F) with
winds from the NNW. With recent precipitation, continuing cool
temperatures, and winds returning to a more favorable direction, we should
hopefully see more activity than we had today.
