Lovely video of the dawn departure. There were a similar number roosting to the easteen end of Loxons that morning, along with an active Sparrowhawk that nearly took my head off.

Ham Wall RSPB.13 October. 6-30am.
My Wife and I left the Shapwick corner car park and cycled along the track to Tor Hide in the dark ,settled down on the benches in hope of seeing the Starlings take to the air, a Great white Egret appeared from the shadows and flew across the water to settle in the reed bed ,as the light gradually increased a murmur arose from the reeds increasing with the dawn light ,a sudden roar and the air was full of swirling birds ,back and forth they flew then they were gone leaving a shadowy bird floating over the reeds, the Marsh Harrier no doubt soon found its morning prey.A short video. click on link.
