Juvenile Black Kite or Yellow-billed Kite - South Africa (1 Viewer)

Hi, I can't decide if these are juvenile Black Kites or juvenile Yellow-billed Kites. My thoughts are
1. is a juvenile Yellow-billed Kite as it was roosting with some adult Yellow-billed Kites, although I know they roost in mixed flocks.
2. I feel is a juvenile Black Kite but was on it's own at the side of a river.

Any thoughts?

Thanks
Kevin

First as aleeady ´ighter bill base, so Yellow-billed, second more difficult

Thanks Tom, anyone else?
