Yeah, I was wondering about that. But I've found some images of other females that seem to have a darker loral area, although not black. I wonder if it looks black because of the light.
I was going on the yellow, as opposed to orange-yellow colours - compare the bottom bird with the top. And look at the lack of yellow/orange at the base of the flight feathers, which is something I'd expect even a young male to have (again, compare with the top bird).
