Buzzard

We fairly often see a bird of prey circling over the fields on the hill opposite us. It's brown and brown-grey and we think it's probably a buzzard. While on the roof today we saw it twice and my eldest shot some clips. 

It soared away over the trees behind us and then reappeared an hour later, back over the fields in front.

This time it was followed by a crow (where the relative wingspans help to prove it is indeed a buzzard). Crows often do this, and usually try to chase away the buzzard as well. We're well out of nesting season with no chicks to protect, so I suppose it must be a territorial thing.
