My daughter Ariel and I were out sledding today, and Ariel said "Wow
dad look at those white birds."
I looked right above us expecting to see pigeons or something, instead
what we saw, and very low to see enough detail,
 was two almost solid white eagle/falcons.  I have never seen one
before in my life, let alone to see two of them together.
They circled around over top of us for a bit and then flew off into
the distance.
These were a pair of white gyr falcons.  VERY rare to ever see them in
Pennsylvania, I even researched sighting maps of the United states and
it does not have them listed in PA at all.
They were beautiful.  Here is a photo of one.  I wish I would have had
a camera with me.  I wonder if seeing something like this is good luck
;)
Here is what they looked like.
