Official Counter: Nate Marchessault, Tom Delaney

Observers: Annamarie Saenger, Chuck Carlson, Dot Currier, Judd Nathan,
Mike Gebo, Robin Feustel, Tom Momeyer

Visitors:
60 visitors throughout the day visited and enjoyed the crisp fall air,
including two school groups.


Weather:
The day started clear with winds from the ENE, mostly cloudy skies in the
afternoon, and a chilly start to mild afternoon. Steady winds from the
northeast throughout the day, getting a little calmer in the afternoon.

Raptor Observations:
A decent pulse of activity mid-morning, with a trickle for the rest of the
day. I had high hopes when an Osprey was right on time for the start of the
count at 9 a.m., but the excitement of kettle after kettle was short-lived.

Non-raptor Observations:
Early in the morning an American Pipit and my first Pine Siskin of the fall
flew over. Shortly afterward, a group of cormorants was seen flying west.
Other than that, a Ruby-crowned Kinglet, towhee, Yellow-rumped Warblers,
and White-throated Sparrows were all observed at the watch or around the
summit. Nice flight of Blue Jays early, but it was also short-lived.

Blue Jays: 27/45
Monarchs: 8/810
Ruby-throated Hummingbird: 1/70


Predictions:
Similar weather is predicted for tomorrow, and potentially slightly lighter
winds, which are favorable. This will be the fourth day in a row with
favorable migration conditions, which typically means less birds. There
will be some birds on the move for sure, but as to whether it will be a big
day or not is up to the birds.
