Marsh warbler at frodsham marsh?
I went to see the possible marsh warbler last night. It was very difficult to see well but I managed a fairly decent view front on whilst it sang low in the reeds. It did seem to have a greyish cast to its brown peaked head. Its white throat stood out. I did not get any good views of the wings or legs. It seemed to like the hawthorn bushes as much as the reeds
Its song was like reed warbler at times and at other times it mimicry was astounding when it got going . I have no experience of marsh warbler in this country and have only seen them a couple of times abroad so I will have to let other more able birders decide if this bird really is one.
