Thanks Kodiak. I'll take that as a compliment to my skills . But I feel like I was lucky when they flew close enough to me to be able to get these. They were very aware of me and tried to avoid me by keeping their distance.
They are fantastic birds to watch - and I have a spot where I go to see a pair and a juvenile. It's quite funny, because the juvenile is getting to know me. It doesn't venture far from the original nesting site but instead stays perched calling for it's parents all day long (I'm assuming to bring food, but I'm sure it's old enough to find it for itself). It has started dive bombing towards me from high up - but not to within a close distance. I'm hoping I'll get the opportunity of some playful flying again on my future visits. I've noticed that the juvenile seems to play fight with it's parents in the sky too, and sometimes I see it harassing it's parents before a brief 'talon lock' and continuing to fly together. Hopefully I'll get to capture more of their behaviour in the future.
