Buzzards over Town Moor

Was out in the back garden this afternoon when I heard a Buzzard call.
Managed to spot it high, very high,  so grabbed the bins and was pleased to see three of them soaring above the Town Moor.
Then they suddenly went into losing altitude at some rate in a S.W. direction and out of sight.
This one below is from a different sighting a couple of weeks agao.
