Deffo a Buzzard, we them here, big imposing birds, but nowhere near the size of a Golden Eagle.
I’ve only ever seen a couple. One at the top of Glen Clova and a pair on Lochnagar. They were unmistakeable. I doubt you’d see them on the south coast by the road.
I think a Sea Eagle is even bigger, we saw a couple over the Lomonds once, they were massive.
