The sunshine took its time pushing back the cloud deck to reach the
mountain, but by the afternoon there were only a few clouds left swept to
the far corners of the horizon. There was a light breeze out of the
northeast, and the temperature rose from just below freezing into the 40s.
There was just enough powder from the flurries overnight to scrape together
the first snowball of the season...

Raptor Observations:
A Red-tailed Hawk soared past the count site first thing in the morning,
followed by nearly half an hour of empty sky that built up anticipation
like a Mark Twain pause. Then in a rush, hawks began to find thermals and
mixed-buteo kettles built on both sides of the ridge. 47 migrants were
counted in the 10am hour alone, more hawks than are seen in total on an
average November day. A gang of 4 young Bald Eagles sparked a tornado of
ravens over North Pack, causing even Nancy to declare, "What a mess!" as we
tried to sort out their intentions to migrate. An immature Golden Eagle
came from the east to join one of the balds as it streamed off towards
