Thanks for the comments on my previous post of sketches of this bird! My sketches were probably the male (he was very high on a power line -- I don't have any binoculars).
This photo is probably the female a juvenile on a branch near the nest. Not sure if it's a Mississippi kite or some kind of falcon, but it is a bird-eater. Over the weekend the male flew close over my head --- I'd say the wind span is about 24".
