Visitors:
95 - an excellent crowd for a Tuesday! Partly thanks to a rescheduled
raptor release, in which we released rehabilitated immature American
Kestrel and Merlin back to the wild. Thanks to Wings of the Dawn in
Henniker, NH for the care of these birds and their continued partnership.
Great to see many old friends and meet many first-time visitors, too!
Thanks to Dawn, Rebecca, Gigi, Brian and Pat, Rick and Suzanna, a Harris
Center 'Natural History of Autumn' course, and others for spending some
time with us.


Weather:
A gorgeous transition of the seasons day. Mostly sunshine interspersed with
well-spaced clouds, and a cool northeast breeze. Excellent visibility,
especially early and late in the day. Good conditions to produce birds!

Raptor Observations:
A great morning for close windblown birds sailing across the ridge and over
the summit in ones and twos. Signs of the broad-winged flight slowing down,
but they're not all gone yet. Fine day for raptor diversity and numbers of
the late-September species. Perhaps a changing of the guard, with the best
day of the season thus far for Turkey Vultures (11), Cooper's Hawks (9),
and Red-tailed Hawk (2), and another strong kestrel flight (16). Male
kestrels punctuated the day with birds showing at key moments, including
the first minute of the count, two circling overhead just five minutes
before noon (when we released a rehabilitated kestrel back to the wild),
and a final hour bird as the last raptor of the day.

Non-raptor Observations:
2 American Herring Gulls, 1 Northern Flicker, 1 Tufted Titmouse, 8
Blackpoll Warblers, and 1 Rose-breasted Grosbeak (only 4th hawk watch
record).
Monarchs: 15/802

Predictions:
Moderate northeast winds and continued sunny skies could continue to push
birds our way and give them lift.
Clarry Hill had a big day today, and Pack often gets birds following these,
so keep an eye out for a final big push of broad-wings ahead of this
weekend's weather.
