Official Counter: Rod Chase

Observers:

Visitors:
Observers: Wendy and Bob Heppler helped at start and Steve Farrell stayed
until 1pm (EST).



Weather:
At 11am: 62F/17C, West wind 0-5mph/0-8kph,
40% overcast with sm. cumulus, Visibility 20mi/32km.
Temp was stable as much larger cumulus rolled in;
by noon 80% o/c and 90% by 2pm.
After 12:30 several small patches of rain moved north
of us about 5 but miles out; Visibility reduced to 5mi/8km
from NW-NE. One dark cloud passed overhead and then poured
on S. Monoosnuc Hill just east of the mountain.
The temp dropped to 60F/17C between 1 & 2pm.
End result was most birds migrated on S side of hill in PM.

Raptor Observations:
Most flights near eyelevel, winds lighter but cold, wet air and heavy
clouds kept thermals to a minimum all afternoon.
Brighter to east so nominal lift available on that side.
Kestrel (male adult) hassled 2 ravens relentlessly for over 5 minutes.
Quite a show.

Local raptors: RT 2, TV 6, Merlin 1.

Non-raptor Observations:
Other locals: 8 ravens up and, with few visitors, we had
several Juncos foraging on the observation deck.

Predictions:
Saturday
Isolated showers after 1pm. Increasing clouds, with a
high near 65. North wind around 8 mph.
