Large Bird of Prey Romney Marsh

Hi, over the past couple of weeks my partner has noticed a few mentions of a large bird of prey on the marsh, all within a few miles radius, mainly between Brenzett and Lydd. We saw one sat on a fence about 30ft from the road, unfortunately i was driving so did'nt get a good look other than it was brown and large. On the same stretch of road someone said they saw it land on the road a little way in front of them and when it took off it had an all brown underside and they thought it was an eagle ! I have since seen what i assume is the same bird cruising high over farmland and the road i was on and to me it looked like a buzzard with a dark brown underside but again i was driving so could'nt have a really good look. Has anyone else seen it ?
