A nice analysis by Dave Leatherman. I'd also point out that part of what gives Prairie Falcons a dark-armpitted look in flight, the contrastingly dark flanks, is also quite apparent while perched. This is demonstrated well by Dave's images; compare the even streaking/barring through the Gyrfalcon's underparts to the Prairie Falcon's denser-streaked flanks.
