A missed call, a bad signal for the call back, finally voicemail R-l B just 5 minutes from the house. (Thanks to AMc).
News that the bird had been seen yesterday evening, across the road from my house, was a bit of a surprise. After a rather mixed up morning I finally got news of the Buzzard. When I arrived it had disappeared South out of view. After10 minutes it reappeared from a different area and gave initially good views before drifting high and North.
Despite searching it wasn't relocated. I am sure it will turn up again.
I'm going to keep photographing these until I gt a good shot.
