In reply to buxtoncoffeelover:
I know what you mean but I don't think so - though I'm not 100% on this because birds can do strange things.
I saw the female first and thought it was the male until the male popped up and I could see that he was properly black whereas she's merely very dark brown, (although her crescent does seem to be very prominent).
Also, the scaly effect was obvious on her but not him, and conversely the pale wing panels were visible on him but not her.
I think that's the best I've done so far with my smartphone and an adaptor (discounting the "stationary" sparrowhawk in my garden), the male was through my binoculars - which felt easier to setup than on my small scope.
