Visitors:
201. It was great to share the day with so many other hawkwatchers and
visitors; lots of excited exclamations, big smiles, and sheer wonder.


Weather:
Crisp September day with excellent visibility all the way to Mount
Washington. Mostly sunny at first, with high cloud cover moving in late
morning. Light northerly breeze at the start; otherwise mostly calm. Temps
rising from low forties to high fifties.

Raptor Observations:
Woohoo! Ideal weather conditions, combined with perfect timing, resulted in
an incredible, record-breaking day on the mountain. Activity picked up
shortly after 11am, with kettle after kettle getting called out across the
sky and being fed by seemingly endless streams of birds from the east. An
exceptional 4,435 broad-wings passed by during the 12 o'clock hour alone,
including one long river of birds flying low behind the trees near the
summit. There were many amazing kettles in the hundreds that often appeared
over North Pack or the Uncanoonuc hills and re-formed right above us. The
last kettle of 210 birds came through during the 3 o'clock hour and then no
more raptors were seen after that. We ended with a new single day high
count for broad-wings, breaking the previous record of 5,208 broad-wings in
2011. And we have now passed 13,000 total raptors for the season!

Non-raptor Observations:
Several woodpecker species including a Northern Flicker perching on top of
a spruce, Pileated Woodpecker flying by low, and juvenile Downy Woodpecker
foraging in a birch. One Ring-billed Gull flying towards the east.

Monarchs: 87/763
Ruby-throated Hummingbirds: 2/69

Predictions:
Rain tomorrow with better weather coming Monday.
