Official Counter: Rod Chase

Observers: Bill Rasku, Rod Chase, Tom Gottschang

Visitors:
On the deck: Rod Chase, Bill Rasku, Tom Gottschang,
George Russell and a newcomer (with good eyes!) Linda
Ferraresso. Familiar and new hikers as well as visitors all seeking updates
on the count! Also two, names not procured but will be able to e-mail the
'intro to hawkwatch at Wachusett' that I send to all who show an interest.


Weather:
A 61F start gradually warmed to 68F at the end while a
light but constant NW+/- wind maxed at 8-12mph with light
gusts 15 in the 9am hour. Then 5-10 mph for all but the
last hour of 0-5mph.
Visibility of 5mi. at start improved quickly to 10 miles
from 9am until 2pm. Cloudiness started and ended at 70%,
with a low of 50% midmorning.
Great breeze and conditions blessed us with '7bpr'
(birds per hour) thru noon. The drop in wind speed at noon
seems the only change that shut down the flight.

Raptor Observations:
8:30am--2pm; 5.5 hrs.
Right from the start we had a steady trickle of migrants
appearing from NW thru NE; estimate 80% ended up passing
on west side of peak. Both kinds of lift were used though
orographic out played the short lived thermals.

BE's: sub-adlt 8:51; sub-adlt 10:10; juv. 11:55.

Locals: ad. BE north; ad. PG north; imm. BE far to NE.
(all were in the 10am hour.) Also 2 ad and 6 imm RT's --
the immatures were up at same time. TV's 8.

Non-raptor Observations:
9 Common Ravens were also up at once -- and around all
day again.
24 Monarchs.

Predictions:
Wednesday
A slight chance of light rain after 2pm. Partly sunny,
with a high near 64. North wind around 6 mph becoming
northeast in the afternoon. Chance of precip. is 20%.
Sounds promising plus Clarry Hill 321 today. ... igottawork :-(
