Sounds like a male Harrier could also be possible, some males can be very
light underneath. They are slender, and can confuse even the best birders
when seen out of their expected habitat. I remember a Christmas Count many
years ago, three of us were looking at the same bird late in the afternoon.
The bird was very high and flying toward us, we called out every ID, as you
have done, and it was not until it was very close that we could see that it
was a female Harrier!  See Sibley's bird book, there is a special note
talking about just this issue, Harriers confusing birders because of where
they are and how they are flying.

Cheers, George Forsyth
