This large bird was circling fairly low over an area of vineyards and scrub. It slowly spiralled upwards in a way very unlike a buzzard.
No interactions present.
One of my favourite raptors. The chequered pattern on the underwing is also quite a useful feature. Nice long wings in proportion to the body too.
