Breeding buzzards

I've been listening to this guy for weeks without being able to see him - buzzard nest completely invisible in clump of Lawson Cypress 70m from the back of my house on my neighbour's property. Finally he's fledged and is exploring the area, flying OK but landing in trees still needs a little work. I only found the nest when he flew back to it. 

We have the buzzards and local ravens to thank for the failure of the rooks' attempt to re-establish themselves here after being partially displaced from Milton Manor.
