How about an adult N. Goshawk?
They will often take on a tight glide pattern flight and will look very
white-ish from below.

Subject: [VTBIRD] White Raptor over Montpelier
At 12:30PM today there was a white raptor over Montpelier being robbed by
crows. I did not have my glasses on so I did not see this bird well, but it
was circling like a Broad-wing but with a fiestier wing beat and flight. It
was almost the exact same size as the crows. Too quick and and the circles
were too tight for a light Rough-legged, plus there were no markings that I
could see. I thought albino RT but the flight was too strong, fast and
I came away thinking it was a possible white-morph Gyrfalcon
Again, I did not see this bird well, but I am writing this so people will
keep there eyes open in Central Vermont. Whatever it was it was beautiful
and definitely worth finding again.
