April 13, 2010:
There was much activity over the reed beds today with up to three birds seen in the air at one time. Often they appeared to scan the area for likely nesting sites, settling on the ground briefly before taking off again and repeating the process. Despite that, there was no sign of nesting material being carried in.
There were several occasions of aerial display, twisting and turning acrobatically. On one occasion a bird perched far out in the middle of the fen on an alder shrub . They are providing considerable interest with cars pulling into the laybys at the roadside to watch.
