Road Scholars, Massachusetts Audubon staff, and Tom Delaney's hiking group
were among the day's 96 visitors. Thank you, everyone who joined us and
helped pick birds out of the sky!

Far beyond Monadnock, one cirrus cloud became several, and by mid-afternoon
the entire sky was a mosaic of snow and glacier meltwater. The air felt
like anything but the highlands of Alaska, with temperatures brushing 80
and the sun reflecting off the rocks underfoot. The light NW wind gradually
shifted to come straight out of the west by day's end.

Raptor Observations:
Birds took there time getting started again today, with a single
Broad-winged Hawk counted before 10am. Not long thereafter, kettles began
to form to the north and east, starting small but building to 30+ birds by
11am. From then until 4pm, there seemed to be birds within view of the
mountain every second, as thermals filed and emptied and streams of hawks
drifted by, many pausing to kettle overhead. Bald Eagles fell shy of tying
the single day record by one bird, mixing in with the broad-wingeds or
forming their own single-species micro-kettles of twos and threes.

Non-raptor Observations:
Non-raptor migrants:
waterbird sp.- 6
Ruby-throated Hummingbird- 2
Eastern Wood-Pewee- 1
Blackpoll Warbler- 3
Yellow-rumped Warbler- 16
Northern Parula- 2
Black-throated Green Warbler- 1
Black-and-white Warbler- 1
warbler sp.- 4

Monarch Butterfly- 7

Overcast skies, a high of 80F, 5-10mph SW wind, and a slight chance of a
passing shower. Not ideal, but as long as the mountain isn't stuck in the
clouds, there should be birds to see.
